\r\n\tIntegrated circuit (IC) forming from the integration of large numbers of very tiny electronic components into a small chip plays a key role in the nowadays circuit industries. Similarly, the circuit board (e.g., the printed circuit board) assembling with many electronic devices and IC components plays a significant role to enrich sciences, technologies and thus the daily applications in the world. A consumer electronic system usually needs a circuit board to integrate all the necessary components for performing the designed functions, such as a personal computer or a smartphone, for example. Consider the advanced developments and applications, the related challenges of manufacturing circuit boards may include materials, very high frequency, electromagnetic interference, energy strategy, flexible manufacture, bio/optic/electronic combination, 3D printing, standards, operating characteristics, recycling issues and so on. This book project intends to provide the reader with a comprehensive overview of the current state-of-the-art of circuit boards including materials and manufacturing technologies, developments and applications as well as the related issues.

In earlier years, physical wedges were typically constructed from high-density materials and fixed to certain wedge angles; they were standard accessories shipped with linear accelerators. Such wedges are usually mounted externally or internally in the gantry head of the linear accelerators. Nonphysical wedges, first proposed in the late 1970s by Kijewski et al., produce modulated dose distributions that were similar to those of physical wedges [1]. They rely on the dynamic movements of a pair of independent collimating jaws during treatment and have been widely implemented in modern radiotherapy machines. Both modalities possess unique advantages and limitations in terms of dosimetric characteristics, treatment accuracy, and efficiency.
\nIn this chapter, we discuss and compare the clinical implementation and application of wedge techniques in radiation therapy.
In radiation therapy, wedge filters are commonly used to improve dose uniformity toward the target volume [2]. A physical wedge is usually constructed from a high-density material, such as lead or steel, which attenuates the beam progressively across the entire field. A nonphysical wedge generates a sloping dose distribution by moving one of the jaws with variable speed, while the opposite jaw remains steady. Nonphysical wedges inherently have no beam attenuation or beam hardening effect and thus offer more flexibility than physical wedges [3, 4]. According to the International Commission on Radiation Units and Measurements, the wedge angle is defined as the angle at which an isodose curve is tilted at the central axis of the beam at a specified depth (usually 10 cm) [5].
\nBefore deciding on physical or nonphysical wedges during clinical treatment planning, the treatment planning system (TPS) requires obtaining a number of measurements from each wedge system. In general, the TPS requires data on the percentage depth-dose (PDD), beam profiles, and wedge factors of the X-ray beams [6]. As an example, Figure 1 shows the profile curve measurements when physical or nonphysical wedges at 30° and 60° were used (field size 10 × 10 cm2).
\nThe profile curves of 10 MV X-ray beams using (a) 30° or (b) 60° of physical or nonphysical wedges under a source-surface distance of 100 cm and depth of 10 cm in water. The red line indicates profile curves of nonphysical wedges; the black line indicates that of physical wedges.
The results show that nonphysical wedges have straighter profile curve lines than physical wedges, which are desirable in clinical practice. These results are consistent with those previously described [7, 8]. Ahmad et al. reported that differences in profiles between physical and nonphysical wedges were most evident in larger fields, shallow depths, thicker wedges, and when using a low-energy beam [8].
\nOn the other hand, the presence of a wedge filter in the path of a radiation beam decreases its intensity; this must be taken into account when calculating treatment doses. When physical wedges were used, photon energy fluence is reduced in the wedged beam compared to the open beam; this effect is more pronounced when increasing the wedge angle [9]. It has also been shown that a physical wedge factor has a stronger depth dependence than a nonphysical wedge factor owing to beam hardening [2].
Before wedge filters are installed in clinical practice, several measurements must be incorporated into the TPS for beam modeling. The modeling method for the TPS varies between manufacturers and also between calculation algorithms, as the mechanism of motion of the nonphysical wedges is different for every manufacturer. In this section, the Eclipse planning system (Varian Medical Systems, Palo Alto, CA, USA) and the Enhanced Dynamic Wedge (EDW, Varian Medical Systems, Palo Alto, CA, USA) are mainly described.
\nA physical wedge changes the beam energy fluence of the primary X-ray beam through the insertion of a metallic filter at the gantry head. This effect is modeled via a wedge transmission curve; specifically, depth doses, wedge profiles, and longitudinal profiles are used for such modeling. In the Eclipse system, the energy fluence of the primary X-ray beam is modeled as a two-dimensional spectrum that considers the mass-energy attenuation coefficient, which is calculated based on the wedge filter material and thickness. Furthermore, the physical wedge produces secondary radiation when interacting with the primary X-ray beam. Eclipse hence considers the wedge a source of scatter, and modeling is performed using a dual Gaussian plane. Moreover, when physical wedges are used in the Eclipse system, a separate electron contamination source model is applied to the calculation; it is necessary to verify the precision of the final model by comparing it to the acquired data before the wedge filters are installed in clinical practice.
\nFogliata et al. compared the calculation models and measurement data using the analytical anisotropic algorithm (AAA) [10–13] and the Acuros XB (AXB) [14–16], which is built into Eclipse (version 10.0) [17]. Six and 15 MV X-rays were validated in their study; measurements were performed in water using the PTW-MP3 phantom with a 0.125 cm2 cylindrical ionization chamber (Semiflex, PTW). Next, depth-dose curves were investigated for several field sizes. In the wedged field along the central axis, the difference in absolute dose between calculated vs. measured values revealed deviations (including standard deviations) smaller than 1%. Moreover, the profile curves were investigated in some field sizes at depths of dmax, 5, 10, 20, and 30 cm. In the central beam region, the average difference in profile curves between calculations and measurements was smaller than 1%, with a standard deviation lower than 1%. Output factor and monitor unit (MU) calculations were also investigated in some field sizes at a source-surface distance (SSD) of 90 cm and a depth of 5 cm in water. The difference between the calculated and measured MUs to deliver a fixed dose to the isocenter exhibited a maximum deviation of 0.2%. Therefore, when using AAA or AXB under reference conditions, it is possible to model correctly. However, when considering clinical use, validation in non-reference conditions is also necessary. Van Esch et al. validated depth-dose curves at SSDs of 80, 90, and 100 cm to verify the accuracy of modeling of the electron contamination as a function of source-to-skin distance [18]. For depth-dose curves involving different SSDs, they reported that the disagreement between calculated and measured data in the buildup region was high under conditions of higher energy and small SSD. In wedge profiles for 60° physical wedges using 18 MV for the selection of asymmetric fields (X = 15 cm, Y1 = 7.5 cm, Y2 = −5 cm), deviations up to 4% in the absolute dose at the center of the field were observed. Hence, accurate modeling using this method is difficult because the wedge produces numerous scattered photons and electrons. For tolerance settings at the time of modeling, please refer to Refs. [19, 20].
\nThe nonphysical wedge produces a distribution similar to that of a physical wedge by moving the collimator jaw and/or modifying the dose rate. In the Varian EDW, only a single jaw is moved; moreover, the dose rate for the Siemens virtual wedge is varied. The EDW uses the segmented treatment table (STT) when planning the position of the moving jaw and corresponding doses. The golden STT (GSTT) is used for a wedge angle of 60°, which controls all other wedge fields (i.e., all the field sizes and the wedge angles) as well as the center axis dose of the open field [21]. In other words, EDW settings do not require any input data for beam configuration other than the open beam data. The movement of the collimator in the EDW affects the primary radiation and scatter components, as well as the backscatter of the collimator. Therefore, it is necessary to verify the accuracy of the modeling by comparing calculated estimates to the measured data.
\nFor the EDW, Fogliata et al. also compared the calculations to the measurements using the AAA and AXB [17]. Moreover, depth-dose curves were investigated in field sizes of 20 × 20 cm2. In wedge fields along the central axis, the difference in absolute dose between the calculations and measurements presented deviations (including standard deviations) smaller than 1%. Furthermore, profile curves were investigated in a field size of 20 × 20 cm2 at depths of dmax, 5, 10, 20, and 30 cm. In the central beam region, the average differences of profile curves between calculations and measurements were smaller than 1%; standard deviations were lower than 1%. Furthermore, output factors and MU calculations were investigated in some field sizes at SSDs of 90 cm and a depth of 5 cm in water. The difference between the calculated and measured MUs when delivering a fixed dose to the isocenter presented a maximum deviation of 0.2%. Validation in a selection of asymmetric fields (X = 15 cm, Y1 = 7.5 cm, Y2 = −5 cm) indicated deviations up to 1.5% in the absolute dose at the center of the field [18]. Furthermore, in a Monte Carlo simulation study, the surface dose of TPS produced large errors of up to 40% compared to Monte Carlo simulation in depth-dose curves [22]. This was attributed to two reasons: First, the calculation of PDDs with TPS is based on ionization chamber measurement data; the measurements of this chamber could be affected by contaminated electrons produced by the moving collimators. Second, the measured surface dose may be averaged incorrectly owing to the erroneous calculation of the ion chamber volume because of the partial volume effect. Monte Carlo simulation indicated that there are significant TPS errors at the outer regions of the field; the maximum relative error of the position difference between TPS and the actual measurements is 20%. Lateral electronic disequilibrium exists in the penumbra regions of the dose profile, especially for smaller field sizes. As mentioned in the American Association of Physicists in Medicine report, TPS cannot accurately calculate backscatter, multiple scattering, or electron disequilibrium in AAA [23]. It is necessary to take into account the calculation precision in the region indicated by the black arrows in Figure 2.

The green line indicates TPS data, the red dots indicate measurement data, and the black line indicates the percentage of error between the TPS and actual measurements.
Tumor motion (i.e., intrafractional organ motion) is an important consideration during radiotherapy [24]. Intrafractional motion can be caused by the respiratory, skeletal muscular, cardiac, and gastrointestinal systems. Respiratory motion in particular affects all tumor sites in the thorax and abdomen; the disease of most relevance in this case is lung cancer, as shown in Figure 3. Of note, respiratory motion is just one potential source of error in radiotherapy [25]. Chen et al. reported that lung tumor motion varies from 0 to 5 cm [26]; Shirato et al. reported that the average amplitude of liver tumor motion was up to 1.9 cm [27], while Hamlet et al. reported that the larynx elevates approximately 2 cm while swallowing [28].
\nThe change over time of tumor motion in the lung between exhalation and inhalation. The red line indicates the contour of the tumor during exhalation; the tumor moves up and down markedly during breathing.
Intrafractional organ motion can result in two types of effect. The first is the “dose-blurring effect,” which results in the over/under dosage of the tumor with radiation. The second is termed the “interplay effect,” which is only a problem in the case of dynamic delivery of intensity-modulated radiation therapy or dynamic treatments with nonphysical wedges. This effect is the result of interplay between the moving tumor and the motion of the radiation beam as defined by the nonphysical wedges [29, 30] and can result in dose discrepancy.
\nThe respiratory-based interplay effects for nonphysical wedges have previously been studied; it was reported that approximately 50% of the organ receives a dose 5–15% higher than that prescribed when the collimator is moved from the caudal to the cranial direction. Conversely, collimator movement in the opposite direction results in under-dosing [29]. Moreover, Kakakhel et al. estimated the interplay effects for nonphysical wedges in a phantom study and reported that more than 90% of the area of the target region was covered by the prescribed dose when the phantom was rested. However, for a moving phantom, less than 70% of the target region was covered by the prescribed dose [24].
\nFor the reasons stated above, nonphysical wedges should be considered with caution before utilization for treatment in cases of respiratory organ motion. On the other hand, physical wedges have limited field sizes, densities, and composition materials; hence, they create more low-energy electrons and photon-scattering radiation than nonphysical wedges [31]. Furthermore, the dose outside the field using nonphysical wedges is half that of physical wedges [32].
The choice of physical vs. nonphysical wedges is critical in several clinical situations. As mentioned above, nonphysical wedges have more liabilities than physical wedges for the treatment of moving tumors. In contrast, physical wedges create more secondary radiation than nonphysical wedges. Petrovic et al. reported that the peripheral dose of the nonphysical wedge field is half that of the physical wedge field; this is owing to scatter outside the physical wedge field that arises from the interaction of the beam with the material of the physical wedge (such interactions include Compton scattering).
\nClinically, this provides an advantage to the nonphysical wedge field [32]. The effect of secondary radiation outside the field is an important consideration for breast cancer treatment. For example, Figure 4 shows how the low-dose area was expanded to the opposite breast when using physical wedges; such secondary radiation exposure may precipitate the development of another tumor. Warlic et al. reported that the average dose outside of the field with a nonphysical wedge was 2.7–2.8%, whereas the dose was 4.0–4.7% with a physical wedge. The nonphysical wedge is hence a practical advance that improves the dose distribution in patients undergoing breast conservation while simultaneously minimizing the dose to the contralateral breast, thereby reducing potential carcinogenic effects [33].
\nThe dose distributions of radiotherapy in a breast cancer patient using (a) physical wedges or (b) nonphysical wedges. Each line indicates the dose corresponding to each treatment intensity planning.
Nonphysical wedges have significant benefits for both the therapists and patients. Saminathan et al. reported that the number of MUs used to deliver a particular dose using a nonphysical wedge field is less than that used for a physical wedge field [2]. Moreover, Njeh reported that using nonphysical wedges results in significant dose reductions to areas outside of the treatment field [34]. The reduction of MUs can also result in minimizing treatment times; this benefits patients who have worse performance statuses.
Each of the two wedge types, physical and nonphysical, has several characteristics that produce both advantages and disadvantages under specific conditions. Clinicians should choose between physical and nonphysical wedges with careful consideration to tumor motion, the effect of secondary radiation, and the performance status of the patient.
The traditional Socratic method (method of Elenchus), has been a form of cooperative argumentative dialog used at learning institutions to stimulate critical thinking for many years. With the development of new technologies in the past 100 years, teaching and learning methods have evolved to add new perspectives and theories. These events have caused lecturers and students to become more active and participative, creating new ways to interact. Nowadays the learning process includes active learning to avoid students receiving passive information that does not relate to their needs. There are considerable studies involving formal education and active learning, but in the case of non-formal education, the information is more limited.
\nThe chapter will describe how non-formal education is used to achieve active learning. The scouting method will be explained and discussed since the scouting movement is the largest youth non-formal active learning community in the world. Subjects such as how semiotic take an important role in this method will be mentioned, and also how the scouting movement uses esthetics and dialogism to achieve the scout’s (learners) development goals.
\nNon-formal education has been described [1] as a flexible education process with a defined methodology and most important, capable of adapting to the needs and interests of students. In this kind of process, time is not a pre-established factor because it is defined by the student’s pace, and it does not seek to provide a formal certification or scholar degree.
\nTo understand the development of non-formal education, it is required to describe formal and informal education. Formal education is a model that has a systematic organized and structured curriculum, which is rather rigid. This process necessarily involves the presence of a teacher, a student, and an institution. Educational institutions administer the curricula and the final goal is to provide some kind of certification or degree [1].
\nInformal education, on the other hand, has no defined structure, it has no curricula and it takes place through experience. It consists of accidental or purposeful ways of collaborating with other persons and acquiring new information and everyday skills [1].
\nIn the beginning, the boundaries between formal, non-formal, and informal education were well defined, but changes are being made due to the COVID-19 pandemic and the normal method evolution. Formal education has adopted non-formal methods to solve some of the online demands of students. At the same time, non-formal education is now using assessment recognition programs (ARCNIL) to get a certification. Svetlik [2], relates that non-formal education has become a social issue. It is mentioned that in order to achieve a more efficient knowledge transfer, formal education has become increasingly dependent, and organized. Non-formal education provides relief of bureaucracy issues. Additionally, non-formal education provides knowledge, but the formalization requirements have increased due to the demand for qualified employees. This has led in some cases to the need of creating some sort of certification for this process.
\nNew knowledge demands require internal labor, and training markets allow the development of individuals with knowledge and skills as core workers. Organizations have established training using non-formal methods that transfer knowledge, and most important “skills” to workers. Svetlik [2], mentions that the assumption that formal knowledge and training could fluently bring formal curriculum and convey students, has been misled. It is argued that this is because teachers tend to overlook interdisciplinary knowledge. There might also be communication barriers between schools or researchers, also some companies might resist sharing firm-specific knowledge to preserve a competitive advantage. Polanyi, 1996 cited by Svetlik [2] mentions: “it is difficult to express a great deal of knowledge in an explicit form, and convey it with school teaching methods” Ideological biases and blindness can also be experimented by formal curricula. Finally, access to certain information can remain restricted due to a limited number of participants.
\nThe information presented so far, leads to believe that formal education must be complemented with non-formal education, to seek not only knowledge but the development of real-life “in situ” skills. Since non-formal education is based on “learn by doing” it develops real-life skills by allowing participants to experience their learning, this is where active learning becomes an important factor for knowledge to take place. To exemplify the relation between non-formal education and active learning, this chapter will describe concepts as they are applied in the World Organization of the Scout Movement (WOSM), which is the largest non-formal education organization in the world.
\nDue to the problems of strategies that formal education programs may experiment to accomplish an integrated formation, non-formal education has been essential.
\nEducational institutions or other types of organizations, favor goal achievements in different areas to contribute to self-realization of the individual.
\nNowadays, young generations have a lack of motor, emotional, and social skills. It seems they are more aggressive, anxious, dependent, and less creative [3]. These are some of the reasons why it is imperative that children, adolescents, and young adults are submerged in extracurricular activities. These activities not only give them tools for life, but they also contribute to the awareness of their learning process, so it can be applied in a formal-educational environment.
\nLearning is a process that implies the way in which people acquire knowledge, or modify the knowledge and skills they possess, in order to improve their task performance [4]. It is an active mechanism that depends on the learner’s cognitive activities. It is facilitated by the analysis and reformulation of previous knowledge, and it results from the interaction and adaptation with the environment, in order to get holistically integrated into the world [5].
\nThe Experiential Learning Theory described by Kolb, D. in 1984 [6], enhances the role of experience in the learning process, and its transformative power to create knowledge. It complements the benefits of active learning since the latter is defined as an engagement of activities to assess people’s understanding and skills. This enables them to handle a particular situation, and keep active in their learning by evaluating, analyzing, and taking action [7]. In this manner, it is important to acknowledge the benefits of deep, meaningful learning, facilitated by this process, since it is a more effective means of education.
\nScouting is a worldwide movement that involves more than 50 million people, distributed in over 200 countries and territories. It is the biggest youth organization in the world, and its mission is to contribute to the self-fulfillment of individuals in order to help them play a constructive role in society [8]. This is made possible by the implementation of a non-formal education process that helps develop capabilities throughout life, in order to make autonomous, supportive, responsible, and committed individuals [9]. Although in some countries or territories, scouting is not necessarily related to academic activities, in some places, scouting is part of the extracurricular activities of elementary (elementary school), secondary (junior high school), and high (senior high school) [10, 11, 12].
\nToday its educational program involves the holistic development of the children, adolescents, and young adults in six basic areas: affectivity, character, creativity, sociability, physical conditioning, and spirituality. Affectivity development is gained by the exploration, identification, and management of emotions, as well as the recognition of their wise use of liberty. Character growth is related to their ability to be congruent with their principles and values. Creativity is obtained through imagination, finding different routes of problem-solving, innovating, project development. In general terms, practicing their thought process. Sociability is developed by solidarity, meaning the identification of common interests and goals through empathy, thus creating a sense of belonging to a social circle. Physical conditioning involves not only the practice of physical activity, acknowledgment of the individual’s limits, and general good health habits, but also contact with nature. This is a very important part of scouting, since it encourages to appreciate the environment’s resources, and how to respect and use them intelligently. Spirituality is gained by the identification of self as a small but important part of the world, creating a sense of inner peace and peace with others.
\nSince the foundation of the scout movement over 110 years ago, the educational program has evolved to attend the youth’s needs, adapting itself to fulfill the requirements of the constantly changing generations. Nevertheless, the way that the program is implemented is based on a system that has been essentially the same since it was originated, and it is key to the organization’s success: the scout method.
\nThe scout method (SM) is defined by the WOSM as a “system of progressive self-education activities”. It is based on the interaction of equally important elements that work together as a cohesive system. The elements are:
\nCommunity involvement: Active exploration and commitment to communities and the wider world, fostering greater appreciation and understanding between people.
\nNature: Learning opportunities in the outdoors encourage a better understanding of the relationships with the environment.
\nLearn by doing: The use of practical actions (real-life experiences) and reflection(s) to facilitate ongoing learning and development.
\nSymbolic framework: A unifying structure of themes and symbols to facilitate learning and the development of a unique identity as a Scout.
\nThe scout promise and law: A personal voluntary commitment to a set of shared values, which are the foundation of everything a Scout does and wants to be. The Promise and Law have a central role in the Scout Method.
\nPersonal progression: A progressive learning journey focused on motivating and challenging an individual to continually develop, through a wide variety of learning opportunities.
\nAdult support: Adults facilitating and supporting young people to create learning opportunities, and through a culture of partnership to turn these opportunities into meaningful experiences.
\nTeam systems: The use of small teams as a way to participate in collaborative learning, with the aim of developing effective teamwork, interpersonal skills, leadership as well as building a sense of responsibility and belonging.
Felder & Brent [13] mention that active learning is a way in which participants assume a dynamic role. They retain more knowledge when they experiment and reflect than just receiving passive information through their senses. Active learning takes time since participants are expected to take action, demonstrate, make models or review information, and finally review their findings.
\nThe SM encourages participants to take an active role, develop skills, work by teams, learn by doing, and most important to make a self-commitment. This aspect becomes fundamental since participants oath to do their best. This concept reinforces active learning since it is the active learner who seeks to develop his full potential.
\nAnother fundamental issue is the work of small groups, young people get to create their own natural team in which they are all friends and each scout has the opportunity to become a leader. These friendship bonds usually last a lifetime since they do not form regular teams as in in formal education. Scout teams called patrols, live experiences that mark them for life, and the stronger the experiences, the stronger the bond that unites them. The patrol becomes the fundamental place in which active learning takes place, they decide which activities to do and ask the adult leaders to help them reach their goals. Patrols interact with each other and constitute a troop and the adults only act as facilitators and advisors for their activities.
\nWOSM has been exploring international development programs in which scouts have been earning Badges by developing projects that are created to solve the needs of the communities where they live. These programs are called “Better World framework”. It’s based on the United Nations Sustainable Development Goals (SDGS). UN [14] states “The Sustainable Development Goals are the blueprint to achieve a better and more sustainable future for all. They address the global challenges we face, including poverty, inequality, climate change, environmental degradation, peace, and justice.”
\nWOSM is part of the United Nations (UN), therefore the adoption of these goals was an organization prerogative. This action created a worldwide active learning community in which youngsters collaborate in a very dynamic way with scouts from other countries. Global awareness became evident and the following international programs were created:
\nMessengers of peace. It’s a scouting initiative, which encourages scouts to do community service and tell the story of their experience in order to inspire others.
\nScouts of the world. Scouting encourages young adults to take action by learning about local problems, creating a service project, and then taking action in the form of voluntary service.
\nDialog for peace. By recognizing that the world is diverse, the scouting movement encourages scouts to learn to find similarities unnoticed before and even come to respect and sometimes appreciate differences to find inclusive solutions to shared problems.
\nInterreligious dialog. This program shows scouts that each form of religion must be respected and its active practice encouraged, scouts may have the opportunity to develop the spirit of mutual goodwill and understanding.
\nScouts Go Solar. It’s an initiative that shows scouts how to harvest solar power and seek to use natural sources of energy.
\nThe World Scout Environment Program. It has been designed to provide scouts with environmental awareness and take action to connect with nature in order to stop pollution and protect the planet.
\nUNESCO World Heritage Recognition. It’s a program that seeks to recognize scouts that promote sustainable development actions.
\nHe for She Program. This program sponsored by the UN teaches scouts that women and men are equal and fundamental to achieve gender equality and allow women empowerment.
Scouting experience in different parts of the world is unique. The culture, economic, social, and security status, influence the ideal execution of the program.
\nCulture plays a transcendental role since not all educational objectives can be developed in the same manner, in countries that have distinctive sets of values, traditions, and customs. Even in the same country, language and family dynamics in different ethnic groups can influence the capability of developing certain goals in an area of interest. This is balanced by the program adaptation in conditions where the culture is not only respected but promoted as well. In many cases, economic status determines the permanence in the movement, where the administrative and operative activities have a cost. As with other institutions, membership fees are adjusted according to budgets, and economic strategies at different structural levels of the institution are suggested in order to minimize the financial burden. Social status, determined by the relationship between people of a broad spectrum of ages and genders, influences their capability of being involved in decision making and their opportunities to develop leadership skills. From the moment their cognitive abilities provide a sense of judgment on the youth, their participation in decision making organs is promoted and guided by the adult volunteers that facilitate their education. Nevertheless, there are still areas of opportunity, inequality is still present in different facets since it is a condition in evolution all around the globe. Security status affects the decision-making process. An inadequate satisfaction of basic necessities such as food and health sets aside the educational activities or modifies their application strategies. A practical example is a condition derived from the Covid-19 pandemic, where in the best-case scenario, people have to adapt to an online environment in order to carry on their education. But since there are areas of personal growth that involve social interaction and physical contact, the program execution gets compromised and it’s more difficult to deliver.
\nThe holistic character of scouting is determined by the growth of different areas of the being. But since its educational program is a balanced set of activities within and outside the scouting environment, there is much to consider in terms of its effectiveness influenced by the social and physical environment status.
\nFriedman & Thellefsen [15] define semiotics as a way to represent knowledge using symbols, this refers to the production and conversion of meaning through the use of ideograms, images, or symbols. These authors mention that there are several systems used to organize and represent knowledge. They imply that a symbolic language may fulfill the following roles:
\nAn interpretative approach, in which each individual might attribute meaning to a symbol by making a correlation between the symbol and some relevant event. This might include a socio-cognitive approach, semiotics, and pragmatics.
\nA descriptive/objectivist approach, where the learning process is guided by a facilitator and might include cognitive science, linguistics, and concept theory.
\nNon-formal education as it is used by the WOSM, uses both of the previous roles with one difference.
\nThe objectivist approach defines the use of specific symbols that transfer knowledge. The meaning of these symbols has been defined by scouting authorities. Since non-formal education as used by the WOSM, has very well-defined educational goals, “badges” have been developed by National Scout Organizations (NSO) around the world to be awarded to youngsters that have achieved an educational objective. This badge is the formal recognition of achievement by the NSO and it is known by the international scouting community. This acknowledgment represents an extra stimulus on the youngster and reinforces the non-formal knowledge acquisition process. The objectivist approach defines the extrinsic representation of the badge. The rules that the youngsters need to comply with to get this badge and the acquaintance that young people are expected to have.
\nThe interpretative approach represents the intrinsic meaning of the achievement. This is one of the most important tools of non-formal education, that has been implemented by the WOSM. Most of these achievement badges are delivered in a ceremonial environment which adds meaning to the occasion. Complex symbolic frameworks are created so youngsters receive an unforgettable ceremony. In this process, the personal esthetic meaning gets added to the learning experience.
\nThe perfect example of semiotics it’s the world scout emblem (fleur de lis) it is worn by scouts and scout liders around the world to indicate their membership. The Scouting movement founder, Lord Robert Baden Powell of Gilwell, selected this emblem (\nFigure 1\n) to represent scouts around the world.
\nWorld scout emblem explained. Copyright WOSM.
As you can appreciate, the world crest is an ideogram that receives an interpretative approach, this interpretation changes depending on which national scout organization uses the emblem. In Latin America National Scout Organizations, this crest also represents the scout oath, and the meaning attributed to it does not represent only an objectivist approach but it goes much further since it becomes enriched by an interpretative meaning often surrounded by an esthetic environment.
\nCasey, et al. [16] mention that an esthetic experience is lived and felt individually, and it relates to a sensory experience in which the person establishes beauty standards. It is a process where the esthetic object exists to be perceived by the audiences. Spectators become witnesses of various forms of sensory data input that is found pleasing to the senses. The important part is that each esthetic experience gets completed only in the consciousness of the spectator, it is an active perceptual engagement between the object and the spectator. It is the personal perception, reflection, and feelings of the person who is experiencing the esthetic phenomenon.
\nNon-formal education as applied by the WOSM provides designed environments to exploit subjectivity. This allows the viewers to become an active part of the action, favoring the appearance of feelings that will be processed by the participant as embodied cognition. This will allow the youngsters to include high-level mental constructs and perform various cognitive tasks that will add personal meaning to the occasion. The SM gets enriched when youngsters not only get recognition for their work but also create personal bonds with other scouts and develop feelings associated with the events in which they were immersed.
\nAdded esthetic value can be found not only in the meaning of the badge given to the youngsters but also by asking their loved ones to be present. In this way, family and friends can be present throughout the entire educational process and provide continuous support.
\nJamail-Nesari [17] cites Bakhtin, M. when he defines dialogism as the process in which meaning is evolved out of interactions among the author, the work, and the listener. These elements are affected by the contexts in which they are placed. Bakhtin argues that understanding cannot be reached if a monologism approach is used, since it will only show an objectified world that corresponds to a single and unified consciousness. Bakhtin comments that monologs turn off the process of dialog, but are often used by formal education as the dominant approach for educational situations since education cannot be purely monological because there is always another perspective present in the classroom. Bakhtin proposes a different approach called Dialogism.
\nJamail-Nesari [17] mentions that dialogism is a model of conversation used to practice speaking and provide examples of language usage. Bakhtin cited by Jamail-Nesari [17] proposes a different meaning for dialogism. It is mentioned “Any utterance, whether spoken or written, that people use in communication with each other is internally dialogic”. For Bakhtin dialog exists not only in spoken words but also in all sorts of expressions, movements, and interactions made to communicate information. Bakhtin proposes that dialogism is a process in which all participants must communicate with each other, there is always room for arguing because dialogism seeks that every person expresses a point of view. This process allows a great deal of freedom for interaction among participants, Bakhtin called this process polyphony (multivoicedness).
\nNon-formal Education as used by WOSM develops polyphony on different scales. The first one and most basic is when the youngsters get to pick their small group (part of the scouting method). Scouts not only choose their team but also their leader and the rules of their patrol, this is done eminently through dialog. Youngsters assign a formal definition of the duties of each member and seek to fulfill them at any time (meaning that scouts will always try to follow the scout principles). This is where most of the active learning occurs, right inside the smallest group, because each patrol member must work directly with other members to develop projects and seek to enhance their knowledge of various subjects. The next level called council level is where different groups get together in a specific region. At this level, Polyphony is worked in a different way through the use of youth forums, in which youngsters get selected by their scout mates to represent them. In these forums, scouts learn about current topics and develop communication skills with adults and other scouts from their region. National forums occur once a year, selected youth participants initiate different communication protocols, they also discuss the problems they are facing and how to solve them. Finally, every four years the biggest scout event in the world unites scouts from over 250 countries and territories to experience the ultimate polyphony discussion. In the World Scout Jamboree, thousands of youngsters get together and adopt the model of the UN to work on the problems their communities and the world are facing. Some topics are decent labor, rights of persons with disabilities (inclusion), human rights, environmental actions, migrants and refugees, gender equity, youth, peace, and security. Each scout representative gets selected to speak about his own country and all the opinions, and conclusions are collected by the WOSM and then shared with the NSO and other institutions that express interest.
\nWOSM has been divided into six regions worldwide, different actions have been taken by all these regions due to the COVID-19 pandemic.
\nAs the pandemic was unexpected, many countries were unprepared to deal with the requirements and the coordination needed to overcome this disease. In response, every NSO started to involve scouts to respond actively to the needs of the community. Several examples of the Better World Framework projects will be mentioned below, with emphasis of the ones developed in the Asia Pacific Scout Region.
\nAfghanistan scouts created public awareness campaigns through the distribution of flyers and social media. Older scouts participated in the disinfection of public spaces, vehicles, residential areas, and orphanages. They also helped with the distribution of food and hygiene packages to families facing starvation due to the lockdown. Additionally, entire scout families got involved in sewing and distribution of face masks to police and medical personnel [18].
\nScouts from Bhutan have done several health awareness actions, giving information to the communities, preparing postcards for handwashing and general prevention Covid 19 prevention messages, to assist in breaking the chain of transmission. Also, generating spaces of experience sharing after illness, in order to help psychological health, and volunteering to do Covid 19 surveillance duty with school teachers and general public [18].
\nScouts from India distributed masks and sanitizers in their communities, organized rallies, door to door campaigns and graphic material for Covid and good health awareness, and posters for local commercial prohibiting entry without masks. They also made food distribution programs for people in need derived from the pandemic, as well as for street animals [18].
\nIn Cambodia, scouts raised funds and organized a food relief operation. Scouts of China issued a COVID 19 guideline and shared it with other countries, they also volunteered to help pack medical masks. Scouts of Fiji focused on homeless people to help them understand the situation and to give them protective equipment. In Kenya, scouts provided families with resources for online school classes, and gave conferences to parents in order to assist their children’s education. The Philippines gathered masks, shields, and raised money to help their communities. Scouts from Sri-Lanka distributed dry foods and vegetables for dozens of families facing difficulties from the pandemic. Many countries have changed their entire program activity set to virtual to avoid more infections, and have similar experiences in the development of projects in order to contribute to the resolution of the pandemic.
\nOne of the most important part of the scouting method involves community engagement, this is where active learning takes place since scouting encourages youngsters not only to develop skills but to support their communities in a practical way. All this indoctrination is made using dialogism, in which scouts find personal meaning to specific words, ideas or even experiences as the ones mentioned above.
\nWhen scouts from all over the world realized that COVID 19 pandemic had exceeded the health sector capacity of Covid prevention and/or treatment, initiatives where taken without waiting instruction of scout leaders. Youth immediately searched for adult guide to identify ways to help persons in need. With the help of their families, they crafted face masks using their own funds, and donated them to hospitals and police stations. Scouts felt better because they were helping the cause and soon started to seek other ways to help the community, this is where esthetics comes in place since scouts are experiencing that they are doing something beautiful that makes them feel proud. Scouts were able to see the results of their work, so they even became more engaged to help the community.
\nAs months passed by, scouting activities have changed, scouts continued to develop prevention materials making face masks and helping with sanitization of public places, thermal screening, and stress management in underprivileged shelter homes. All this process is being documented and it is being presented to the NSO. So participant scouts can get the international badge known as “Messengers of Peace” (MOP). This is where semiotics take place since all the persons who bear the MOP have contributed to the development of their own communities through a project. Scouts who earned the MOP badge attribute a special meaning to it, since it represents their own effort to help and participate in an active learning procedure in which they overcome all sorts of obstacles to fulfill their goal. These five elements combined, act directly into the youngster’s development and learning objectives.
\nActive learning is one of the best ways to potentiate learning. Involvement creates interactions that enable youngsters to have a better understanding of different learning processes that they should go through. Non-formal education was designed to learn “in situ”, and one of the most important cornerstones of it is “learn by doing”, making non-formal education a foundation for active learning.
\nThe program and SM of WOSM has proven for over 110 years to be one of the best places for active learning in the world. Millions of scouts work daily to ensure this, not only creating local interactions and regional activities but working with other scouts worldwide to develop joint projects that seek to answer their community needs.
\nThis chapter presented how the world scout movement uses non-formal education and active learning to develop educational goals worldwide. It also explained the program, methodology, and core foundations of scouting. This gives a better understanding of how active learning is used in scouting, and the elements that the scouting movement developed over a century ago that helped build the largest youth community in the world.
\nThe pandemic of COVID 19 changed the entire social and economic scenario. The scouting movement was not prepared to work entirely online. Scouting program was designed based on a face to face interaction, in this sense, adjustments had to be done worldwide to ensure the continuation of the movement. Despite this, online scouting is a reality and need to keep adjusting to youth’s needs and interests. This also means that there is an opportunity area within adult training, because of the lack of abilities on information technologies and social networks. Even additional educational strategies that do not rely on technology can be helpful, in order to avoid the issues of lack of resources such as computer equipment or internet access.
\nFinally, one of the biggest contributions of scouting to active learning has been to develop a methodology that involves playing and learning at the same time, in this way, youth has an enjoyable time while learning actively and helping others.
