The Effect of a Multi-Component Consultation Intervention on the Pragmatic Language Skills of Students with Symptoms of Attention Deficit Hyperactivity Disorder

The purpose of this research was to determine if a multi-component consultation intervention was effective in improving pragmatic performance in students with ADHD. Participants for this study consisted of 7 children for whom 3 data points were obtained by a parent or 2 data points by a teacher. Changes in pragmatic performance were measured by comparing reports provided by parents or teachers pre- and post- intervention. Descriptive analysis procedures were completed to summarize changes in pragmatic behavior. Results revealed the mean overall change in pragmatic behavior for children in the MCC condition (Χ=1.133) was greater than the change seen in the CAU condition (.334) after 2 months of intervention as per parent reported data. Data indicated improvement in each behavior but incongruence between teachers and parents was found. Results support the hypothesis that the multi-component consultation intervention is effective in improving the pragmatic language performance of children with ADHD.

The Relationship of Culturally Responsive Instruction and the Reading Comprehension and Attitude of Struggling Urban Adolescent Readers

Culturally responsive instruction refers to the identification of relevant cultural aspects of students’ lives and infusion of these into the curriculum. This instructional approach assumes that a culturally appropriate curriculum can potentially motivate, engage, and lead students to higher rates of achievement. This quasi-experimental study (N=44) investigated the relationship of culturally responsive instruction and the reading comprehension and attitude of struggling urban adolescent readers. The study incorporated the use of culturally responsive instruction using culturally relevant literature (CRL), the Bluford Series Novels, as authentic texts of instruction. Participants were seventh grade reading students at a Title I middle school in South Florida. After a baseline period, two different classes were taught for 8 weeks using different methods. One class formed the experimental group (n=22) and the other class formed the comparison group (n=22). The CRI curriculum for the experimental group embraced the socio-cultural perspective through the use of small discussion groups in which students read and constructed meaning with peers through interaction with the Bluford Series Novels; gave written responses to multiple strategies according to SCRAP – Summarize, Connect, Reflect, Ask Questions, Predict; responded to literal and inferential questions, while at the same time validating their responses through evidence from the text. The Read XL (basal reader) curriculum of the comparison group utilized a traditional form of instruction which incorporated the reading of passages followed by responses to comprehension questions, and teacher-led whole group discussion. The main sources of data were collected from the Gates-MacGinitie Reading Tests, the Florida Assessments for Instruction in Reading (FAIR), and the Rhody Secondary Reading Attitude Assessment. Statistical analyses were performed using Repeated Measures ANOVAs. Findings from the study revealed that the experimental participants’ reading attitudes and FAIR comprehension scores increased when compared to the comparison group. Overall, the results from the study revealed that culturally responsive instruction can potentially foster reading comprehension and a more positive attitude towards reading. However, a replication of this study in other settings with a larger, more randomized sample size and a greater ethnic variation is needed in order to make full generalizations.

The Relationship of Instructor Technical Literacy to the Academic Performance of Students in Career Academies

Career Academy instructors’ technical literacy is vital to the academic success of students. This nonexperimental ex post facto study examined the relationships between the level of technical literacy of instructors in career academies and student academic performance. It was also undertaken to explore the relationship between the pedagogical training of instructors and the academic performance of students. Out of a heterogeneous population of 564 teachers in six targeted schools, 136 teachers (26.0 %) responded to an online survey. The survey was designed to gather demographic and teaching experience data. Each demographic item was linked by researchers to teachers’ technology use in the classroom. Student achievement was measured by student learning gains as assessed by the reading section of the FCAT from the previous to the present school year. Linear and hierarchical regressions were conducted to examine the research questions. To clarify the possibility of teacher gender and teacher race/ethnic group differences by research variable, a series of one-way ANOVAs were conducted. As revealed by the ANOVA results, there were not statistically significant group differences in any of the research variables by teacher gender or teacher race/ethnicity. Greater student learning gains were associated with greater teacher technical expertise integrating computers and technology into the classroom, even after controlling for teacher attitude towards computers. Neither teacher attitude toward technology integration nor years of experience in integrating computers into the curriculum significantly predicted student learning gains in the regression models. Implications for HRD theory, research, and practice suggest that identifying teacher levels of technical literacy may help improve student academic performance by facilitating professional development strategies and new parameters for defining highly qualified instructors with 21st century skills. District professional development programs can benefit by increasing their offerings to include more computer and information communication technology courses. Teacher preparation programs can benefit by including technical literacy as part of their curriculum. State certification requirements could be expanded to include formal surveys to assess teacher use of technology.

Peer interaction in mixed age groups: a study in the computer area of an early childhood education center in Portugal

The study was developed as a teacher-research project during initial teacher education – Masters Degree of Early Childhood and Primary Education, in Portugal. It analysed the interactions between children of 3 to 6 years old, during the use of the computer as a free choice activity, confronting situations between peers of the same age and situations between peers of different ages. The focus of the analysis was the collaborative interactions. This was a qualitative study. Children could choose the computer, amongst other interest areas, and work for around an hour in pairs. In the computer, children used mainly educational games. During four weeks, the interactions between the pairs were audio recorded. Field notes and informal interviews to the children were also used to collect data. Eleven children were involved in the study with ages ranging from 3 to 6 years old. Baseline data on children’s basic computer proficiency was collected using the Individualized Computer Proficiency Checklist (ICPC) by Hyun. The recorded interactions were analysed using the types of talk offered by Scrimshaw and Perkins and Wegerif and Scrimshaw: cumulative talk, exploratory talk, disputational talk, and tutorial talk. This framework was already used in a study in an early childhood education context in Portugal by Amante. The results reveal differences in computer use and characterize the observed interactions. Seven different pairs of children's interactions were analysed. More than a third of the interactions were cumulative talk, followed by exploratory talk, tutorial talk and disputational talk. Comparing same and mixed age pairs, we observed that cumulative talk is the more present interaction, but in same age pairs this is followed by exploratory talk whereas in the mixed age pairs it is tutorial talk that has the second largest percentage. The pairs formed by the children were very asymmetrical in terms of age and computer proficiency. This lead to the more tutorial interactions, where one children showed the other or directed him/her on how to play. The results show that collaboration is present during the use of a computer area in early childhood education. The free choice of the children means the adults can only suggest pairing suited to specific interactions between the children. Another way to support children in more exploratory talk interactions could be by discussing the way the older children can help the younger ones beyond directing or correcting their work.

Why Physical Geography? An analysis of justifications in teacher magazines in Germany

School geography is often quite different from academic geography and there are good reasons for that, as school is preparing young people to be able to lead the life they value instead of just training them to learn specific subject contents. In some countries school geography is understood as being mainly a social science. Nonetheless physical geography often plays an important part in textbooks and in everyday teaching in these countries. This presentation will examine how physical geography topics are justified in specialist teacher magazines in Germany. Are they justified by simply pointing at the value of the academic knowledge itself? Are they justified by claiming students’ special interest in these topics? Or are they justified by showing the value of physical geography in promoting social aims such as sustainable development, freedom or equality?

L’interaction comme méthode d’apprentissage du Français langue étrangère (FLE) en Suède

Mon travail s’inspire de l’idée de la Direction nationale de l’enseignement scolaire suédoise (Skolverket, 2011) qui suggère que « les élèves doivent avoir la possibilité de développer une capacité de communication et de compréhension de la langue ». Mon mémoire commence par une introduction générale, continue avec une analyse des manuels utilisés dans l’apprentissage du FLE et des activités favorisant l’interaction - échange réciproque verbale ou non verbale, pour terminer par une conclusion générale. Comme il n’existe pas d’enseignement sans méthodes appropriées, il existe des manuels qu’on peut utiliser afin de faciliter l’apprentissage par l’interaction de la langue cible. Les activités de communication orale et écrite d’ordre pédagogique sont indispensables. Tout comme l’écrit Revue française de pédagogie (1994 :133) « La classe est un système social complexe dont les parties sont en interaction dynamique, acteurs (enseignant et élève[s]), situation, matière selon des statuts sociaux. ». Pour effectuer mes recherches, j’ai porté mon attention sur l’analyse des manuels scolaires qu’il m’a été permis de consulter. Il s’agit des manuels d’entraide comme : Mais oui 3 et Escalade littéraire. Concernant l’analyse du matériel didactique favorisant l’interaction, ces deux manuels proposent des exercices de réflexion selon le niveau de l’apprenant. Dans mon travail, je m’intéresse à l’aspect didactique et linguistique de ces deux manuels scolaires.

Vidéos contre lectures: Une évaluation de l'utilisation de vidéos pour accomplir la construction initiale de connaissances

Abstract : The goal of this study was to determine whether providing videos for students to watch before class would be more effective than assigning readings. The study took place within a flipped classroom: a methodology designed to engage students in the initial construction of knowledge before class, freeing up classroom time for active learning pedagogies. Preparing for class by watching videos should require less of the students’ time than doing readings, and they should respond better to videos than to readings because these more closely mimic this generation’s interactions with information and media. Consequently, flipped classroom students provided with videos should perceive a lower workload, which could translate into more positive learning outcomes. From an instructor’s perspective, however, developing and organizing videos is extremely time consuming. Thus, a teacher giving consideration to flipping their class would likely want to know whether videos would lead to positive outcomes for their students before actually committing to developing these. However, no research to date was identified which has examined the question of whether flipped class videos would be more effective than readings. The hypotheses for the study were that videos would result in measurable learning gains for the students, and would lead to lower time demands and perceived workloads, as well as more positive attitudes. These were tested using a quasi-experimental design involving a convenience sample of two small college General Biology 1 courses taught by the same teacher. One group had videos to watch before class for the first 1/3 of the course (treatment; Class A), during which the other was assigned readings (control; Class B). Following this, both groups were provided with videos. Student scores were compared on pre-instruction and in-class quizzes, activities, four unit tests, and a final exam. Further, students completed a 44 item survey as well as a demographic questionnaire. Results suggest greater learning gains for students provided with videos. Certainly, students from Class B improved significantly when provided with videos, especially as compared to Class A, whose improvement over the same time span was marginal. However, conclusions based on these results are somewhat tentative, as Class A performed rather poorly on all summative assessments, and this could have driven the patterns observed, at least partially. From the surveys, Class B students reported that they spent more time preparing for class, were less likely to do the necessary preparations, and generally perceived their effort and workload levels to be higher. These factors were significant enough that they contributed to four students from Class B (10% of the class) dropping the course over the semester. In addition, students from both groups also reported more positive attitudes towards videos than readings, although they did not necessarily feel that videos were (or would be) a more effective study and learning tool. The results of this study suggest that any effort on the part of an instructor to prepare or organize videos as pre-class instructional tools would likely be well spent. However, even outside of the context of a flipped classroom, this study provides an indication that assigned readings can place heavy workload requirements on students, which should give cause for any instructor employing mandatory readings to reassess their approach. Finally, since both groups were statistically equivalent across all measured demographic variables, it appears that some of the observed disparities in assessment scores may have been driven by differences in group dynamics. Consequently, the suggestion is made that an instrument to measure classroom climate should be incorporated into any research design comparing two or more interacting groups of students, as group dynamics have the potential to play a key role in any outcomes.||Résumé : L'objectif de cette étude était de déterminer si fournir des vidéos aux étudiants avant une classe serait plus efficace comme méthode d’apprentissage individuel que de leur donner une liste de lectures à compléter. L'étude a eu lieu dans une classe renversée – une stratégie plus reconnu sous le nom de «classroom flipping» – ce qui ce trouve à être une méthodologie qui vise à obliger les élèves d’accomplir le transfert de connaissances initial avant la classe, en vue de libérer du temps de classe pour des activités pédagogiques plus approfondie. En théorie, pour les élèves, se préparer pour une classe renversé en regardant des vidéos devrait exiger moins de temps que d’être obligé à apprendre le matériel en lisant. En plus, présenter le matériel d’un cours avec des vidéos imite de plus près les genres d’interactions qu’on les étudiants de cette génération avec de l'information et les médias, ce qui devrait faciliter leur tâche. Par conséquent, les élèves d’une classe renversée fournies avec des vidéos devraient percevoir une charge de travail moins élevée, et ceci pourrait se traduire en bilans d'apprentissage plus positifs. Cependant, du point de vue du professeur, avoir à développer et organiser des vidéos se présente comme un gros défi, surtout en vue du temps et de l’effort qui sont requis. Ainsi, un enseignant qui songe à renversée sa classe voudrait probablement savoir si le fait d’offrir des vidéos mène à des résultats positifs avant de réellement s'engager dans le développement de ces derniers. Par contre, lors de l’écriture de ce texte, aucune étude n’a été identifié qui répond à cette question, et aucune publication compare la performance des étudiants lorsqu’ils ont des vidéos à regarder avec lorsqu’ils sont obligés de faire de la lecture pour se préparer. Alors, les hypothèses de l'étude étaient que des étudiants ayant accès à des vidéos démontreraient des gains d’apprentissages évidents, qu’ils apercevraient des requêtes de temps moins encombrantes et une charge de travail plus faible, et, en vue de ces derniers, que les étudiants auraient des attitudes plus positives envers le cours et le matériel. Les hypothèses ont été testés à l'aide d'un modèle quasi-expérimental, avec comme échantillon deux classes collégiales de Biologie générale 1, tout les deux enseignés par le même professeur. Un de ces groupes avaient accès à des vidéos pour se préparer pour chaque classe lors du premier tiers du cours, alors que l’autre groupe étaient obligé de faire de la lecture. Après le premier tiers du cours, ce qui fut 10 des 30 classes du semestre, les deux groupes ont été fournis avec des vidéos pour le restant du cours. Des notes ont été ramassées et comparées sur des mini-examens préparatoires avant et durant les classes, sur des activités complétées en classe, sur quatre examens en classe, et un examen final. En outre, les étudiants ont rempli un questionnaire composé de 44 items, ainsi qu’un autre questionnaire démographique. Les résultats de l’étude suggèrent qu’une décision d’offrir des vidéos aux élèves peut mener à des gains d'apprentissage plus élevés comparativement à l’option lecture. En particulier, les élèves du groupe initial de lecture se sont considérablement améliorées lorsqu'ils ont été fournis avec des vidéos, surtout par rapport au groupe initial de vidéos, dont l’amélioration durant la même période était marginale. Cependant, ces conclusions sont un peu incertaines, parce que la performance du groupe initial de vidéos était globalement médiocre, ce qui aurait pu mener aux résultats observés. Par contre, les résultats obtenus des questionnaires étaient moins incertains, et indiquent que les élèves qui se sont vues attribués des lectures passaient plus de temps pour préparer leurs classes, étaient plus aptes à ne pas faire les préparatifs nécessaires, et ont aperçus leurs niveaux d'efforts et leurs charges de travails comme étant plus élevés. Ces facteurs étaient suffisamment importants qu'ils ont contribué au fait que quatre étudiants du groupe de lecture, soit 10% de la classe, ont abandonnés le cours durant le premier tiers du semestre. Finalement, les élèves ont démontrés des attitudes plus positives envers les vidéos, bien qu'ils ne trouvaient pas nécessairement que ceux-ci étaient plus efficaces que les lectures lorsqu’ils voulaient étudier pour les examens. Basé sur ces résultats, il est possible de conclure que tout effort de la part d'un instructeur pour préparer ou organiser des vidéos pédagogiques serait probablement un bon investissement. En plus, et même en dehors du contexte d'une classe renversée, cette étude offre une indication qu’une stratégie pédagogique qui oblige les étudiants à faire beaucoup de lecture peut imposer des exigences et une charge de travail très élevée pour les étudiants, ce qui devrait donner cause à tout instructeur qui attribue des lectures à réévaluer leur approche. Enfin, puisque les deux groupes étaient équivalents d’un point de vue statistique sur toutes les mesures démographiques, il semble que certaines disparités entre les deux groupes dans les notes d'évaluation et d’examens peuvent possiblement avoir été entraînées par des différentes dynamiques dans chaque group. Par conséquent, il est suggéré que des mesures de relations entre étudiants et de dynamiques de groupes devraient être incorporé dans n’importe qu’elle recherche comparant deux ou plusieurs groupes d’étudiants, et surtout quand ces étudiants sont en interaction, parce-que en toute apparence les dynamiques de groupes ont le potentiel de jouer un rôle clé dans les résultats obtenus.

ESL teacher profiles of ICT integration in their classroom practices and assessment activities : a portrait viewed through the lens of some Quebec teachers’ social representations

Abstract : Information and communication technologies (ICTs, henceforth) have become ubiquitous in our society. The plethora of devices competing with the computer, from iPads to the Interactive whiteboard, just to name a few, has provided teachers and students alike with the ability to communicate and access information with unprecedented accessibility and speed. It is only logical that schools reflect these changes given that their purpose is to prepare students for the future. Surprisingly enough, research indicates that ICT integration into teaching activities is still marginal. Many elementary and secondary schoolteachers are not making effective use of ICTs in their teaching activities as well as in their assessment practices. The purpose of the current study is a) to describe Quebec ESL teachers’ profiles of using ICTs in their daily teaching activities; b) to describe teachers’ ICT integration and assessment practices; and c) to describe teachers’ social representations regarding the utility and relevance of ICT use in their daily teaching activities and assessment practices. In order to attain our objectives, we based our theoretical framework, principally, on the social representations (SR, henceforth) theory and we defined most related constructs which were deemed fundamental to the current thesis. We also collected data from 28 ESL elementary and secondary school teachers working in public and private sectors. The interview guide used to that end included a range of items to elicit teachers’ SR in terms of ICT daily use in teaching activities as well as in assessment practices. In addition, we carried out our data analyses from a textual statistics perspective, a particular mode of content analysis, in order to extract the indicators underlying teachers’ representations of the teachers. The findings suggest that although almost all participants use a wide range of ICT tools in their practices, ICT implementation is seemingly not exploited to its fullest potential and, correspondingly, is likely to produce limited effects on students’ learning. Moreover, none of the interviewees claim that they use ICTs in their assessment practices and they still hold to the traditional paper-based assessment (PBA, henceforth) approach of assessing students’ learning. Teachers’ common discourse reveals a gap between the positive standpoint with regards to ICT integration, on the one hand, and the actual uses of instructional technology, on the other. These results are useful for better understanding the way ESL teachers in Quebec currently view their use of ICTs, particularly for evaluation purposes. In fact, they provide a starting place for reconsidering the implementation of ICTs in elementary and secondary schools. They may also be useful to open up avenues for the development of a future research program in this regard.

the health and well-being of nursing students in clinical practice . what prevents it? what promotes it?

Introduction: The training of nursing students in the context of clinical practice, is characterized by educational experiences, subject to various emotional stress (stress, ambivalence, frustration, conflict), sometimes making it very vulnerable student.However not all students use the same strategies minimizing their meanings and negative effects on the level of your health and well-being Objetiv:To analyze the perception that nursing students have about the determinants of their health status and well-being in clinical practice Methods: Exploratory research Results:The results reveal the complexity of the teaching / learning process in clinical practice, identified determinants that limit and / or promote health and well-being of students, or not contributing to their motivation, self-confidence and learning. All students value the presence of the following dimensions: affective-emotional (humanization in learning experiences); relational dynamics (interactions developed with all stakeholders); methods used (professional competence of the clinical supervisor and teacher); school curriculum (adaptation of learning in theory); socialization to the profession (become nurse).Conclusions: The results indicate, that although all students evidencing the dimensions described as fundamental to learning in clinical practice, the study results are dichotomous and ambivalent. Students 2nd and 3ºanos refer a low perception in clinical practice, the indicated dimensions, and for these source of concern and uncertainty in learning, such as limiting their health condition and well-being. For students of the 4th year, these dimensions are percecionadas as gifts, and sources of motivation, learning and catalysts such as promoting their health and well-being.

The Students’ Perspective of Geometry Teaching and Learning in High School

The purpose of this article is to present the results obtained from a questionnaire applied to Costa Rican high school students, in order to know their perspectives about geometry teaching and learning. The results show that geometry classes in high school education have been based on a traditional system of teaching, where the teacher presents the theory; he presents examples and exercises that should be solved by students, which emphasize in the application and memorization of formulas. As a consequence, visualization processes, argumentation and justification don’t have a preponderant role. Geometry is presented to students like a group of definitions, formulas, and theorems completely far from their reality and, where the examples and exercises don’t possess any relationship with their context. As a result, it is considered not important, because it is not applicable to real life situations. Also, the students consider that, to be successful in geometry, it is necessary to know how to use the calculator, to carry out calculations, to have capacity to memorize definitions, formulas and theorems, to possess capacity to understand the geometric drawings and to carry out clever exercises to develop a practical ability.

Communication in the Seventh Grade Classroom

Reflections on communication in the learning process at the level of the seventh year of secondary education based on the methodological and pedagogical approaches, considered in research of a multidisciplinary team of the CIDE of UNA (National University), with the aim of building the “teaching performance profile for the seventh year of Costa Rican education”. It demonstrates the role of teachers to ensure favorable communication links to the learning process, not only to capture the attention and interest of students through varied and systematic motivations, but also by the honesty, openness, personal example and involvement in the task, problems and aspirations of students.

Pedagogical Mediation for the Autonomy of Future Professionals in Teacher Training

This article studies the importance of pedagogical mediation in helping first-year students in the Teacher Training area to advance from intellectual heteronomy to intellectual autonomy. It explains some strategies and experiences implemented by the authors. It focuses on the need of paying attention to students in order to understand their expectations, opinions and previous experiences as a basis for developing different topics and concepts, to favor an actual free participation in the pedagogical mediation dynamics and, consequently, opportunities for students to express themselves with autonomy. The aforementioned strategies allow for the transition from a pedagogy centered on teaching to a pedagogy centered on learning, in such a way that the future educator becomes a protagonist in his/her formation and constructs his/her own intellectual identity, based on the concept of action-reflection-action. The authors of this article consider that the first year in higher education is a privileged opportunity to develop the autonomy of future teachers, and, as stated by Freire (2004), the respect for autonomy is an ethical imperative.

Competencies Required in Education Research and Teaching Systematization according to Students from the Preschool, Primary and Secondary Education Programs of the University of Costa Rica

The purpose of this paper is to present the results of two online forums carried out with the participation of 42 students of the Licenciaturas  in Preschool Education, Primary Education and Secondary Education of the University of Costa Rica. The main purpose of the forums was to determine the insights of the participant students about the competencies they have achieved in the field of education research, and which have been the essential tools for them to systematize their own teaching practices. The discussion forums were part of the course FD5091 Métodos de Investigación Educativa [Education Research Methods] of the School of Teacher Education, delivered from March-April 2010.  Of the sample, 60 percent were students of the Preschool teaching program, 35 percent were from the Primary Education teaching program and 5 percent were from the Secondary Education teaching program in the fields of Science, Mathematics and Social Studies. According to the insights and beliefs showed by the participants –both, the future teachers and the profession practitioners–, there are no opportunities for research or systematization of their own teaching mediation, in the current work situation.(1) Translator’s Note: In Costa Rica, the “Licenciatura” is a one-year post-Bachelor study program, usually including thesis. “Primary Education” refers to students from the 1st to 6th grades, and “Secondary Education” refers to students from the 7th to 11th grades.

Thermodynamic Study Of The Micellization Of Zwitterionic Surfactants And Their Interaction With Polymers In Water By Isothermal Titration Calorimetry.

The micellization of a homologous series of zwitterionic surfactants, a group of sulfobetaines, was studied using isothermal titration calorimetry (ITC) in the temperature range from 15 to 65 °C. The increase in both temperature and the alkyl chain length leads to more negative values of ΔGmic(0) , favoring the micellization. The entropic term (ΔSmic(0)) is predominant at lower temperatures, and above ca. 55-65 °C, the enthalpic term (ΔHmic(0)) becomes prevalent, figuring a jointly driven process as the temperature increases. The interaction of these sulfobetaines with different polymers was also studied by ITC. Among the polymers studied, only two induced the formation of micellar aggregates at lower surfactant concentration: poly(acrylic acid), PAA, probably due to the formation of hydrogen bonds between the carboxylic group of the polymer and the sulfonate group of the surfactant, and poly(sodium 4-styrenesulfonate), PSS, probably due to the incorporation of the hydrophobic styrene group into the micelles. The prevalence of the hydrophobic and not the electrostatic contributions to the interaction between sulfobetaine and PSS was confirmed by an increased interaction enthalpy in the presence of electrolytes (NaCl) and by the observation of a significant temperature dependence, the latter consistent with the proposed removal of hydrophobic groups from water.

Effects Of Programmed Physical Activity On Body Composition In Post-pubertal Schoolchildren.

To assess body composition modifications in post-pubertal schoolchildren after practice of a physical activity program during one school year. The sample consisted of 386 students aged between 15 and 17 years and divided into two groups: the study group (SG) comprised 195 students and the control group (CG), 191. The SG was submitted to a physical activity program and the CG attended conventional physical education classes. Body composition was assessed using body mass index (BMI), percentage of body fat (%BF), fat mass (FM), and lean mass (LM). A positive effect of the physical activity program on body composition in the SG (p<0.001) was observed, as well as on the interaction time x group in all the variables analyzed in both genders. A reduction in %BF (mean of differences = -5.58%) and waist circumference (-2.33cm), as well as an increase in LM (+2.05kg) were observed in the SG for both genders, whereas the opposite was observed in the CG. The practice of programmed physical activity promotes significant reduction of body fat in post-pubertal schoolchildren.
