Effects of 6-month soccer and traditional physical activity programmes on body composition,cardiometabolic risk factors,inflammatory, oxidative stress markers and cardiorespiratory fitness in obese boys

Physical activity is important in obesity prevention, but the effectiveness of different physical activity modalities remains to be determined among children. The main purpose of this study was to compare the effects of a 6-month soccer programme and a traditional physical activity programme on changes in body composition, cardiometabolic risk factors, inflammatory and oxidative markers, cardiorespiratory fitness and perceived psychological status in obese boys. Eighty-eight boys (8–12 years; BMI > +2 standard deviations of WHO reference values) participated in one of three groups: soccer, traditional activity and control. Soccer and traditional activity programmes involved 3 sessions per week for 60–90 min at an average intensity of 70–80% of maximal heart rate. Control group participated in activities of normal daily living. All boys participated in school physical education, two sessions per week of 45–90-min. Measurements were taken at baseline and after 6 months, and included body size and composition, cardiometabolic risk factors, inflammatory and oxidative markers, cardiorespiratory fitness and perceived psychological status. Physical activity and dietary intake were assessed before and immediately following the intervention. The three groups had similar characteristics at baseline. After 6 months, both intervention groups had significantly lower relative fatness (% fat), waist circumference and total cholesterol, and higher cardiorespiratory fitness, self-esteem, perceived physical competence and attraction to physical activity compared with control group. In conclusion, physical activity interventions over 6 months positively influenced several indicators of health status among obese boys. The results also suggested that soccer has the potential as an effective tool for the prevention and reduction of childhood obesity and associated consequences.     

Effects of an intervention programme with teachers on the development of positive behaviours in Spanish physical education classes

Background: The physical education (PE) context has been emphasised as an ideal environment for developing positive behaviours among students. Under the Positive Youth Development paradigm, various initiatives have been conducted with the aim of promoting personal and social responsibility among adolescents. Self-Determination Theory has been widely used to analyse students’ motivational processes during PE classes.

Purpose: This study aimed to measure the effects of a multidisciplinary intervention with teachers on the development of positive behaviours in PE classes.

Participants: Twenty PE teachers participated in the study (M_age?=?35 years; SD?=?2.32) along with 777 of their students (M_age?=?12.81 years; SD?=?.93). The teachers (male?=?16; female?=?4) were between the ages of 29 and 48 years (M?=?35.2 years; SD?=?2.32). The students who participated in this study (male?=?377; female?=?400) were divided into 52 classes and were between the ages of 12 and 16 years (M?=?12.81; SD?=?.93).

Research design: A quasi-experimental design was used that consisted of a control group and three groups in which an intervention was developed. In the control group, the teachers did not receive any type of intervention; in the second group, the teachers received a training programme to develop strategies for supporting basic psychological needs and promoting positive behaviours; in the third group, the teachers received a didactic unit to promote positive behaviours; and in the last group the teachers received a combination of the two previous interventions.

Data analysis: A repeated-measures ANCOVA (analysis of covariance) was used for every dependent variable included in the study to analyse the effect of Group?×?Time interaction, including Gender and Grade Level as covariates. The fixed effects caused by Intercept, Group, Time, and the Group?×?Time interaction were calculated using compound symmetry as the type of covariance and restricted maximum likelihood as the estimation method.

Findings: By examining the differences between pre-test and post-test, it was determined that in comparison with the students in the control group, the students from the three experimental groups had generally improved scores on the variables related to positive behaviours, such as perceptions of the teacher's support, as well as the development of the targeted behaviours.

Conclusions: These results provide information about the efficacy of an intervention programme with teachers that consists of strategies for developing positive behaviour and support for basic psychological needs to promote the development of positive student behaviour.     

The impact of the university context on European students' learning approaches and learning environment preferences

This article describesexperiences of 610 Dutch students and 241students from other European countries whostudied at least three months abroad within theframework of an international exchange program.The Dutch students went to a university inanother European country and the foreignstudents went to a Dutch university. By meansof a questionnaire students' perceptions ofthree main characteristics of the universitylearning environment were measured concerningthe home university, the host university andthe ideal learning environment. The studentswere also asked about their way of learning atthe home university and at the host university,in particular about the extent of constructivelearning and reproductive learning. Evidencewas found for the influence of aspects of thelearning environment on the two learningapproaches; e.g., a learning environmentcharacterized as student-oriented discouragesreproductive learning and promotes constructivelearning, especially when conceptual andepistemological relations within the learningdomain are stressed. The learning environmentpreferences of the students were partly relatedto their learning orientations at the homeuniversity, but they were strikingly similarfor students from different countries. Therewas a strong preference for those learningenvironment aspects that promote constructivelearning.     

The recent process of decentralization and democratic management of education in Brazil

Brazilian society is beginning a new historical period in which the principle of decentralization is beginning to predominate over centralization, which held sway during the last 25 years. In contrast to recent Brazilian history, there is now a search for political, democratic and participatory decentralization more consonant with grass-roots aspirations. The first section of this article presents a brief analysis of some decentralization policies implemented by the military regime of 1964, and discusses relevant facts related to the resistance of civil society to state authoritarianism, and to the struggle for the democratization and organization of civil society up to the end of the 1970s. The second section analyzes some new experiences of democratic public school administration initiated in the 1970s and 1980s. The final section discusses the move toward decentralization and democratization of public school administration in the new Federal and State Constitutions, and in the draft of the new Law of National Education.

Zusammenfassung Die brasilianische Gesellschaft beginnt einen neuen Abschnitt in ihrer Geschichte, in dem das Prinzip der Dezentralisierung über die in den letzten 25 Jahren vorherrschende Zentralisierung dominiert. Im Gegensatz zur jüngsten brasilianischen Geschichte wird nunmehr eine politische, demokratische und partizipatorische Dezentralisierung gesucht, die mit den regionalen Bestrebungen besser vereinbar ist. Der erste Teil dieses Artikels enthält eine kurze Analyse einiger 1964 vom Militärregime eingeführter Dezentralisierungmaßnahmen und untersucht relevante Fakten, die mit dem Widerstand der zivilen Gesellschaft gegen die Staatsgewalt und mit dem Kampf um Demokratisierung und eine Organisation der zivilen Gesellschaft bis Ende der 70er Jahre zusammenhängen. Im zweiten Teil werden einige neue Erfahrungen den in der 70er und 80er Jahren eingeführten Verwaltung öffentlicher demokratischer Schulen analysiert. Im Schlußteil geht es um die Entwicklung zur Dezentralisierung und Demokratisierung der öffentlichen Schulverwaltung in den neuen Bundes- und Staatsverfassungen und im Entwurf des neuen Gesetzes zu Nationaler Bildung.

Résumé La société brésilienne entame une nouvelle ère historique caractérisée par une prédominance du principe de décentralisation sur celui de centralisation, qui a prévalu durant les 25 dernières années. Par comparaison à l'histoire brésilienne moderne, on vise actuellement une décentralisation politique, démocratique et fondée sur la participation, qui soit plus en harmonie avec les aspirations du peuple. La première partie du présent article contient une brève analyse des politiques de décentralisation appliquées par le régime militaire de 1964, et discute les faits pertinents relatifs à la résistance de la société civile à l'autoritarisme de l'Etat, et à la lutte pour la démocratisation et l'organisation de la société civile jusqu'à la fin des années 70. La deuxième partie analyse quelques expériences récentes concernant la démocratisation de l'administration de l'école publique, inaugurée dans les années 70 et 80. La dernière partie examine le passage à la décentralisation et à la démocratisation dans l'administration de l'école publique dans la nouvelle constitution fédérale et dans celles des Etats fédérés, ainsi que dans le nouveau projet de loi sur l'Education nationale.

     

The new educational pluralism in Latin America

Conclusion Education is, however, already beginning to reflect the whole range of pluralisms that constitute the relatively complex, urbanized and semi-industrialized societies of most of Latin America.Modernity in these societies assumes the form of cultural pluralism with a centrifugal and fragmented social basis, in which deep divisions of class and social strata still exist alongside emerging tensions due to the spread of markets, privatization in civil society, the disintegration of the traditional state, the rapid internationalization of communications and expectations, and the consolidation of liberal-democratic regimes that enable all this diversity to be expressed more freely.The new pluralism of Latin American education has therefore more to do with the modernization of societies and their cultures than with the more restrictive notion of complementarity among well-structured socio-cultural elements that fight to preserve their identity and that attain a form of expression recognized by the state in the field of education. The latter type of pluralism, found in more stable and better structured societies, is replaced in Latin America by a more fluid and ambiguous educational pluralism which, in the final analysis, reflects a process of construction of modernity that began only recently but is now in full swing.

Spiral and Project-Based Learning with Peer Assessment in a Computer Science Project Management Course

Different learning methods such as project-based learning, spiral learning and peer assessment have been implemented in science disciplines with different outcomes. This paper presents a proposal for a project management course in the context of a computer science degree. Our proposal combines three well-known methods: project-based learning, spiral learning and peer assessment. Namely, the course is articulated during a semester through the structured (progressive and incremental) development of a sequence of four projects, whose duration, scope and difficulty of management increase as the student gains theoretical and instrumental knowledge related to planning, monitoring and controlling projects. Moreover, the proposal is complemented using peer assessment. The proposal has already been implemented and validated for the last 3 years in two different universities. In the first year, project-based learning and spiral learning methods were combined. Such a combination was also employed in the other 2 years; but additionally, students had the opportunity to assess projects developed by university partners and by students of the other university. A total of 154 students have participated in the study. We obtain a gain in the quality of the subsequently projects derived from the spiral project-based learning. Moreover, this gain is significantly bigger when peer assessment is introduced. In addition, high-performance students take advantage of peer assessment from the first moment, whereas the improvement in poor-performance students is delayed.     

Evolution in Freedom? The Meanings of ‘Free School’ in Chile

This article examines the background in which enterprises called free schools, as well as complementary educational activities, have taken root in Chile. Two kinds of recently burgeoning free schools are identified; one supplementing regular schooling with a social justice focus, and another that is a fully fledged alternative to other schooling. The history of freedom itself in Chile is explored from a historical perspective, contrasting somewhat with freedom as it is understood in more developed countries. Parallels to Anglophone free schools such as AS Neill’s Summerhill are also discussed, as well as the sociopolitical context in which Chilean free schools continue to develop.     

Automated summary evaluation with inbuilt rubric method: An alternative to constructed responses and multiple-choice tests assessments

Automated summary evaluation is proposed as an alternative to rubrics and multiple-choice tests in knowledge assessment. Inbuilt rubric is a recent Latent Semantic Analysis (LSA) method that implements rubrics in an artificially-generated semantic space. It was compared with classical LSA’s cosine-based methods assessing knowledge in a within-subjects design regarding two validation sources: a comparison with the results of rubric scores and multiple-choice tests, and the sensitivity of predicting the academic level of the test-taker. Results showed a higher reliability for inbuilt rubric (from Pearson correlation coefficient .81 to .49) over the classical LSA method (from .61 to .34), and a higher sensitivity using binary logistic regressions and effect sizes to predict academic level. It is concluded that inbuilt rubric has a qualitatively higher reliability and validity than classical LSA methods in a way that is complementary to models based on semantic networks. Thus, it is concluded that new automated summary evaluation approaches such as the inbuilt rubric method can be practical in terms of reliability and efficiency, and, thus, they can offer an affordable and valuable form of knowledge assessment in different educational levels.     

The Effectiveness of Teaching Geometry to Enhance Mathematical Understanding in Children with Down Syndrome

ABSTRACT

It is widely known that people with Down syndrome have difficulties transitioning from a basic understanding of counting and cardinality to more advanced arithmetic skills. This is commonly addressed by resorting to the mechanical use of algorithms, which hinders the acquisition of mathematical concepts. For this reason some authors have recently proposed a shift in the focus of learning from arithmetic to more fertile fields, in terms of understanding. In this paper we claim geometry fits this profile, especially suited for initiating children with Down syndrome into mathematics. To support this we resort to historical, epistemological, and cognitive reasons: the work of Séguin and his intuition on the central role of geometry in the development of abstract thinking in the so-called idiot children, the ideas of René Thom about the role of continuum intuition in the emergence of conscious thinking, and finally the two strengths people with Down syndrome display: visual learning abilities and interest in abstract symbols. To support these ideas we present the main findings of qualitative research on elementary mathematics teaching to a group of seven children (3–8) with Down syndrome in Spain. The didactic method used, naturally enhance their naïve geometrical conceptions.
