La calidad en la educación abierta y a distancia en México

Abstract

Since 1947, distance education in Mexico has had an important role for nonconventional populations. Considering that distance education is a heterogeneous and dynamic field, it is important to reflect on the need to improve quality as measured by our own standards. With that perspective in mind, a national meeting was organized to start a self‐diagnosis in which quality and access were the main concerns. Five hundred and twenty specialists from fifty‐one institutions participated in a national interactive synchronous meeting held in four regions. As a result of the meeting, thirty‐five criteria and 230 parameters of quality were established. The main conclusion of the meeting refers to the need for the elaboration of our own indicators for open and distance education.     

Transformative Pedagogy: Emergent Bilinguals and Perspective Taking

This study contributes to the limited research on emergent bilinguals, perspective taking, and second language reading of informative text. The explicit integration of Freire’s (1993) notion of conscientizacao, or consciousness-raising, with the constructs of empathy and embodiment (Gee, 2001; Hurtado, 1996) and with translanguaging (García, 2009) represented conceptual frameworks that explicitly guided the pedagogical approaches implemented in the study. The findings indicated that the incorporation of the integrated conceptual frameworks with the prescribed fourth grade social studies curriculum enabled emergent bilinguals to generate their own perspectives concerning social justice and equity when studying about slavery in Texas.     

Dynamic Transition Patterns in Acculturation Among Hispanic Adolescents

Acculturation consists of multiple domains (i.e., cultural practices, identifications, and values). However, less is known about how acculturation processes influence each other across multiple domains of acculturation. This study was designed to investigate transition patterns of acculturative processes within and across domains in a sample of 302 recent-immigrant Hispanic adolescents, M_age (SD) = 14.51 years (0.88) at baseline; male = 53%). Adolescents were assessed six times over a 3-year period. Latent profile analyses identified two profiles (high [or increasing] vs. low) for each domain at each timepoint. We found largely stable transition patterns in each domain over six timepoints. Importantly, sequential associations among profiles in acculturation domains were also detected. Implication for acculturation theory and research are discussed.     

Effect of 6-weeks WBVT on the behaviour of the lower limb muscle fibres during vertical jumping

The purpose of the current study was to examine the effect of 6 weeks of whole body vibration training (WBVT) on body composition, muscle activity of the gastrocnemius and vastus lateralis, gastrocnemius muscle architecture (static and dynamic) and ground reaction forces (performance jump) during the take-off phase of a countermovement jump in young healthy adult males. A total of 33 men (23.31 ± 5.62 years) were randomly assigned to a whole body vibration group (experimental group, EG_WBVT: n = 17; 22.11 ± 4.97 years) or a control group (CG: n = 16; 24.5 ± 6.27 years). The total duration of the intervention phase (WBVT) was 6 weeks with a frequency of 3 sessions per week. Statistically significant differences were observed (P ≤ 0.05) between pre- and post-test in the power peak (Δ 1.91 W · kg^?1; P = 0.001), take-off velocity (0.1 cm · s^?1; P = 0.002) and jump height (Δ 0.4 cm; P = 0.002) for EG_WBVT. There were no statistically significant differences in any of the body composition and muscle architecture variables. Moreover, no significant differences were found between EG_WBVT and CG nor changes in muscle activity during take-off phase of the gastrocnemius and vastus lateralis pre- versus post-training. This study suggests that a 6-week WBVT programme with increasing intensity improves jump performance but does not alter muscle activity nor muscle architecture in healthy young men.     

Becoming a teacher: the thoughts of undergraduates training to work in Primary Education and ideas for their university education

ABSTRACT

What makes a good teacher and what motivates a person to want to teach are timeless questions that concern us all. This study focuses on those who are currently training to become teachers, more specifically undergraduates studying a degree in Primary Education in the universities of Catalonia. It adopts a quantitative methodology based on a self-administered questionnaire conducted with a representative sample. Participants’ open-ended responses are recorded and codified. Three main categories are constructed: personal, authentic teacher; the teacher as story teller; and, the teacher as motivator of learning. Results highlight important differences between these categories, extolling above all the authentic, personal teacher, who leaves a mark thanks to their character and way of being. This, together with other findings, raises various considerations for the university training of future teachers.     

La diferencia de sexo en la resolución de problemas aritméticos: un estudio transversal

Resumen

En este trabajo se estudia la diferencia entre los sexos en la resolución de problemas aritméticos verbales. Participaron 1.078 escolares de los grados 3.°, 4.°, 5.°, 6.° y 8.° de E.G.B. Se aplicó una prueba de 17 problemas aritméticos a los escolares de 3°, 4° y 5° en dos sesiones. También se aplicó una prueba de 4 problemas aritméticos a los escolares de 6.° y 8.° Los resultados indican que sólo en 8.° los varones son más hábiles que las mujeres resolviendo este tipo de problemas. Se hacen algunas consideraciones adicionales sobre los factores del contexto familiar y escolar que puedan incidir sobre los resultados.
