The anticipation of the beginning of Elementary School for six-year-old children, recently imposed by the Brazilian federal law, brought controversies and debates about the organization of the curriculum, routines, contents and activities, spaces and objects, conduct of behavior of teachers and parents, as well as about the policies of teachers’ training, amongst other issues. The present article, supported by advances of scientific production on children formal education, considers the changes in the concepts of children education and, consequently, in curricular practices. For this purpose, games and fun are taken as object of analysis and discussion, and the playfulness is proposed as a central curricular axle in the initial years of Elementary Education.

This paper intends to reflect on the search, in the process of teaching formation, of pre-defined contents for the teaching of Geography and History in the series of primary school. This desire for clarity about the appropriated contents for the various series often overshadows the real need to clarify what is the goal of teaching this or that content. It is necessary, in the teacher training, resume and historically contextualize this search for curriculum contents. The risk of prioritizing the discussion about contents is transforming the contents itself into the content goals of education. Reifying the contents contributes to the common process of disconnect teaching from learning. In this case, the educational process becomes a contest of teaching contents, not bothering if these contents were or not learned by the students, which makes education extremely conservative. This phenomenon has it origins in the 1970s, during the curriculum discussions of the various areas of school knowledge. Since then, the concept of didactic transposition has been questioned progressively, in which the curricula were designed as adapted teaching to lower levels of scientific knowledge produced in universities – the place for higher education. The school knowledge, since the 1970s, is considered as autonomous. In other words, knowledge in dialogue with university science, but with typical characteristics of education in school systems. If the curriculum of primary and secondary educations is not the result of the didactic transposition, what content it should be made of? The current paper touches this issue, but subordinates it to most relevant questions about the purposes of learning in inseparable connection with teaching.

This survey attempted to find out whether or not the management styles adopted by schools can be associated with teacher stress. The study considered 175 teachers working with 1st‑to 4th grades in twelve public schools. The instruments first identified the leadership style predominant in the schools, then sought to identify the presence of stress in the teachers. Although stress was present in the majority of the teachers, an association with specific management styles could not be confirmed. This can be linked to the fact that the stress was already present in the teachers and did not allow the identification of additional influence by the schools’ leadership style

This cross-sectional study aimed to evaluate the load carried by students in primary and secondary schools, state Vespasian /MG, and quantify the percentage established between backpack weight and body mass of these young people carry every day. The study included 916 students of both genders. Ages ranged from 10-19 years. 541 students (59.06%) carried the load backpack ranging from 10.02 to 33.43% of his body mass. Students with younger age, female students and those who opted for the backpack model designed dorsal attachment tended to carry a load higher than 10% of his body weight. 224 (24.45%) students complain of back pain and shoulder. It was concluded that the cargo is inadequate from the point of view of biomechanics and ergonomics, especially for younger individuals and females, since they are in growth phase, and this exposes them to an overhead increased risk of spinal injuries, with consequent repercussions in adulthood.

This paper seeks to understand the mediation of cultural products devoted to childhood in the children's play culture. This research focused on a dialogue between the TV cartoons, which are foods to playfulness and fantasy that characterize childhood cultures; the ethics, because the questioning of symbolic mediators (ideas, values, norms, rules) are essential to reflect on the society we want to live, and Physical Education as a curriculum component, shall contribute to the critical mediation of the body culture and the sports arising out from the media, which has close relation with the practical and moral problems that arise in the classroom. To analyze the narrative structures of cartoons we have adopted the comprehensive methodology of Joan Ferrés. Such method suggests a hermeneuticphenomenological approach, which allowed to access Paul Ricoeur’s hermeneutics; as one interpretative method, it allows the reflection on our values, and also the values presented by the audiovisual product, and possible changes. Successive readings indicate that the narrative structure of TV cartoons responds to a double moral standard, which are constructed from stereotyped models between good and evil, right and wrong, villain and hero, and propose universal role models of conduct. However, some cartoons, mostly based on animé productions, have broader visions of the human common living experiences. We concluded that the current symbolic production of childhood cultures proposes one challenge to the Physical Education teacher: the critical mediation of values related to the movement body culture. Along with the support of moral philosophy, it can target his/her practice for understanding the different manners of (re)creation of the ways, and the living in society.

This work aims presenting and discussing the conceptual (re)construction of the Biological Sciences undergraduate students on the genotype-phenotype relationship. Data collection occurred through a group of researchers systematic monitoring, at weekly discussion meetings. The data were analyzed and discussed based on Bachelard epistemology foundations. The analysis of the results suggests that the inclusion of discussions of historical and epistemological issues, in that research group, favored reflections that contributed to the expansion of the thinking about the genotype-phenotype relationship.

The objectives this research are: (a) describing positive interactions established between teacher and student, considering clinical group to behavior problems and non-clinical one; (b) describing behavior repertoire (social skills and behavior problems) of children with and without clinical classification to behavior problems, according to TRF, teacher version. The participants this study were 16 female teachers who indicated and evaluated 32 students - 16 of them presented behavior problems (with BP – clinical group), whereas the other 16 did not (without BP – non clinical group). Students aged 6 years were enrolled in the first year of elementary school. Data collection was conducted through the application of three instruments: TRF, RE-HSE-Pr and QRSH-Pr, as an interview with teachers. Data were categorized and analyzed to compare the clinical and nonclinical groups (Mann-Whitney Test). Overall, this research found that female teachers exert different practices among students who have behavior problems that do not show, being more skilled in the interactions with children without behavior problems and more agressive to those with behavioral problems. Implications for interventions and public policies are discussed.
