El objetivo propuesto en el presente estudio fue determinar el tipo de motivación, desde la perspectiva de la autodeterminación, en estudiantes de enseñanza media, hacia la clase de Educación Física del Liceo Antonio Varas de la Barra en Arica, Chile, y su relación entre nivel de estudios y sexo. Participaron 717 estudiantes de 1ro a 4to medio. El instrumento utilizado fue la Escala del Locus Percibido de Causalidad en Educación Física (adaptación española). Entre los resultados se hallaron resultados medios-altos (5.09 y 5.22) para las dimensiones de Motivación Intrínseca y Regulación Identificada, respectivamente; mientras que las dimensiones Regulación Introyectada y Regulación Externa presentaron valores medios, 4.49 para la Regulación Introyectada y 4.72 para la Regulación Externa. Por su parte, la no motivación alcanzó un valor medio-bajo (3.70). Genéricamente, los varones aparentaron valores más alto que las damas, en todas las dimensiones, excepto en no motivación, sin embargo, estas diferencias no resultaron ser significativas estadísticamente. Se arribó a la conclusión de que la Motivación Intrínseca, la Regulación Identificada caracterizan a la población estudiada, la no motivación mostró resultados bajos, por lo que los alumnos de enseñanza media, sobre todo, los hombres de niveles superiores, se hallan motivados por la clase de Educación Física. Abstract. The objective proposed in the present study was to determine the type of motivation, from the perspective of self-determination, in high school students, towards the Physical Education class of the Antonio Varas de la Barra High School in Arica, Chile, and its relationship between level of studies and sex. 717 students from 1st to 4th grade participated. The instrument used was the Scale of the Perceived Locus of Causality in Physical Education (Spanish adaptation). Among the results, medium-high results (5.09 and 5.22) were found for the dimensions of Intrinsic Motivation and Identified Regulation, respectively; while the Introjected Regulation and External Regulation dimensions presented average values, 4.49 for Introjected Regulation and 4.72 for External Regulation. For its part, non-motivation reached a medium-low value (3.70). Generically, men appeared higher values ​​than women, in all dimensions, except non-motivation, however, these differences were not statistically significant. It was concluded that Intrinsic Motivation, Identified Regulation characterize the studied population, non-motivation showed low results, so that high school students, especially men of higher levels, are motivated by the P.E. Class.

Information and Communication Technology has changed the way of learning and sharing the knowledge in the education sector. Students prefer to participate and learn in web based environment. But they can be benefitted in this environment only if they have internet self-efficacy. The objective of this paper is to construct an "Internet Self-efficacy Scale" which can be used to determine the internet related ability and skills of secondary school students. The internet self-efficacy scale was administered to 350 students studying in ninth and tenth grades. Initially a preliminary draft of scale comprising 51 statements was constructed. After review and evaluation of statements by the experts, statements were reduced to 33. The 17 statements were retained in the final draft of the scale. The results of test-retest reliability indicate that the scale is reliable with reliability coefficient 0.89. Content validity was calculated and the scale developed was found to be valid.

Teenage pregnancy is one of the social problems in South Africa and is of great significance, as it affects the education of young girls. Previous studies indicate that pregnant teenagers are more likely to be at risk of complications of pregnancy than older women. The aim of this study was to investigate the knowledge and attitudes toward teenage pregnancy among high school learners. A sample of 181 learners was taken from three selected schools in Eastern Cape. The learners were recruited and served as study participants. Data was collected using a self-administered questionnaire, which was designed to measure the knowledge and attitudes toward teenage pregnancy. Descriptive and inferential statistics were used to analyze the data. The results showed an 11.7 percent prevalence of teenage pregnancy among the learners. The learners sampled from the three selected schools were found to have positive knowledge and attitudes regarding teenage pregnancy. The results of the study may inform teenage pregnancy prevention and intervention strategies aimed at high school learners.

The objective of this systematic review was: to identify the main results achieved by research evaluating body composition in children of different ethnicities living at high altitudes. A systematic review was carried out using the prism method, searching for information in databases such as PUDMED, SCOPUS, and SCIELO. The elements used for the search were: population, children, adolescents, obesity, overweight, ethnic groups, altitude and characteristics of body composition. Among the main results, it was found that 4345 (78.8%) boys and girls had normal weight, while 15.43 percent were overweight and obese. Concluding that, in indigenous populations with age groups from 0 to 14 years, there was a predominance of normal weight, observing high values of overweight and obesity in preschool ages.
