The fragmentation of knowledge in physical education

The study aimed at diagnosing the conceptual formation in physical education in Chilean high school students. The study used a descriptive cross-sectional methodology. A total of 659 students participated, 54% boys and 46% girls, aged between 13 and 14 years old, from the three educational units in the country; public schools (36.4%), subsidized schools (37.8%) and private schools (25.8%). A stratified probabilistic sampling was performed based on students' educational dependence and gender. For the data collection, a questionnaire designed and validated with students of the Chilean curriculum was applied. The main results indicate that there are statistically significant differences between educational units, with specific results from Anova off= 48,584 p <.05 in favor of private schools. In conclusion, the study shows a low disciplinary domain of the students in the different educational units, highlighting once more the need to seek innovative methodologies within this discipline in order to improve the learning of its conceptual dimension

Association between the Sociodemographic Characteristics of Parents with Health-Related and Lifestyle Markers of Children in Three Different Spanish-Speaking Countries: An Inter-Continental Study at OECD Country Level

The purpose of this cross-cultural study was to determine the association between the sociodemographic background of a child's parents (i.e., their socioeconomic level, marital status, and educational level) with the child's lifestyle (i.e., Mediterranean diet (MD), physical activity (PA) and screen time (ST)), and health markers. Material: This cross-sectional study included 1273 children, from Chile (n = 496), Colombia (n = 340), and Spain (n = 437). The sociodemographic information together with the lifestyle and health markers of the children were measured. There was an inverse association between a low or medium-low socioeconomic level for the parents of Chilean children and handgrip strength (beta -0.61, p = 4 h per day (OR 1.82, p = 0.020). In conclusion, in Spanish-speaking children, the lifestyle and health markers of the children are affected by the sociodemographic background of their parents; however, these effects could be moderated by the socio-cultural and economic status of their countries as members of the OCDE; therefore, it is essential to develop policies that decrease these gaps, so that children who are under-resourced can reach their full potential
