Abstract

Although Web 2.0 has changed students’ roles, placing them at the centre of the teaching-learning process, attitudes towards Web 2.0 have been observed to have a relation with its use in a formal academic context. An instrument was applied to higher education students in Mexico to explore their perceptions by collecting information on students’ attitudes, training and use of Web 2.0, and its impact on higher education. The findings showed that training in Web 2.0 determines use of it, as well as the attitudes towards it and the possible impact these can have on teaching-learning processes. No differences were found regarding participants’ gender in relation to their perceptions of the use of Web 2.0 as a learning environment.  相似文献

Unemployment and Work Interruption among African American Single Mothers: Effects on Parenting and Adolescent Socioemotional Functioning   总被引：12，自引：0，他引：12  

Vonnie C. McLoyd  Toby Epstein Jayaratne  Rosario Ceballo  Julio Borquez 《Child development》1994,65(2):562-589

Using interview data from a sample of 241 single African American mothers and their seventh- and eighth-grade children, this study tests a model of how 2 economic stressors, maternal unemployment and work interruption, influence adolescent socioemotional functioning. In general, these economic stressors affected adolescent socioemotional functioning indirectly, rather than directly, through their impact on mothers' psychological functioning and, in turn, parenting behavior and mother-child relations. Current unemployment, but not past work interruption, had a direct effect on depressive symptomatology in mothers. As expected, depressive symptomatology in mothers predicted more frequent maternal punishment of adolescents, and this relation was fully mediated by mothers' negative perceptions of the maternal role. More frequent maternal punishment was associated with increased cognitive distress and depressive symptoms in adolescents, and consistent with predictions, these relations were partially mediated by adolescents' perceptions of the quality of relations with their mothers. Increased availability of instrumental support, as perceived by mothers, predicted fewer depressive symptoms in mothers, less punishment of adolescents, and less negativity about the maternal role. Both economic stressors were associated with higher levels of perceived financial strain in mothers, which in turn predicted adolescents' perceptions of economic hardship. Adolescents who perceived their families as experiencing more severe economic hardship reported higher anxiety, more cognitive distress, and lower self-esteem.  相似文献   

W5″ Test: A simple method for measuring mean power output in the bench press exercise     

Julio Tous-Fajardo  Gerard Moras  Sergio Rodríguez-Jiménez  Albert Busquets  Iñigo Mujika 《European Journal of Sport Science》2016,16(8):940-947

The aims of the present study were to assess the validity and reliability of a novel simple test [Five Seconds Power Test (W5″ Test)] for estimating the mean power output during the bench press exercise at different loads, and its sensitivity to detect training-induced changes. Thirty trained young men completed as many repetitions as possible in a time of ≈5?s at 25%, 45%, 65% and 85% of one-repetition maximum (1RM) in two test sessions separated by four days. The number of repetitions, linear displacement of the bar and time needed to complete the test were recorded by two independent testers, and a linear encoder was used as the criterion measure. For each load, the mean power output was calculated in the W5″ Test as mechanical work per time unit and compared with that obtained from the linear encoder. Subsequently, 20 additional subjects (10 training group vs. 10 control group) were assessed before and after completing a seven-week training programme designed to improve maximal power. Results showed that both assessment methods correlated highly in estimating mean power output at different loads (r range: 0.86–0.94; p?R²: 0.78). Good to excellent intra-tester (intraclass correlation coefficient (ICC) range: 0.81–0.97) and excellent inter-tester (ICC range: 0.96–0.99; coefficient of variation range: 2.4–4.1%) reliability was found for all loads. The W5″ Test was shown to be a valid, reliable and sensitive method for measuring mean power output during the bench press exercise in subjects who have previous resistance training experience.  相似文献   

Innovative Training of In-service Teachers for Active Learning: A Short Teacher Development Course Based on Physics Education Research     

Genaro Zavala  Hugo Alarcón  Julio Benegas 《Journal of Science Teacher Education》2007,18(4):559-572

In this contribution we describe a short development course for in-service physics teachers. The course structure and materials are based on the results of educational research, and its main objective is to provide in-service teachers with a first contact with the active learning strategy “Tutorials in Introductory Physics,” developed by the Physics Education Research Group at the University of Washington. The course was organized in a constructivist, active learning environment, so that teachers have first to experience, as regular students, the whole Tutorial sequence of activities: Tutorial pre-test, Tutorial, and Tutorial Homework. After each Tutorial, teachers reflect on, and recognize their own students’ learning difficulties, discussing their teaching experiences with their colleagues in small collaborative groups first and the whole class later. Finally they read and discuss specific Physics Education Research literature, where these learning difficulties have been extensively studied by researchers. At the beginning and at the end of the course the participants were given the conceptual multiple-choice test Force Concept Inventory (FCI). The pre-/post-instruction FCI data were presented as a practical example of the use of a research-based test widely used in educational research and in formative assessment processes designed to improve instruction.  相似文献   

Strategy and factors for success: The Mexican handicraft sector     

Jos de la Paz Hernndez Girn  María Luisa Domínguez Hernndez  M. C. Julio Cesar Jimnez Castaeda 《Performance Improvement》2007,46(8):16-26

This study analyzed the success factors in the Mexican handicraft sector on the basis of marketing strategies. As a result of this work, 23 factors for success that artisans use as marketing strategies were determined. The most important, because it was related to all of the other elements of success, was a pricing strategy oriented to profits. The second most important strategy was to use personal recommendations to promote the products. Product diversification and the information artisans gave to customers were, respectively, the third and fourth strategies.  相似文献   

Short-term optimal load training vs a modified complex training in semi-professional basketball players     

Tomás T. Freitas  Julio Calleja-González  Jorge Carlos-Vivas  Elena Marín-Cascales 《Journal of sports sciences》2019,37(4):434-442

This study investigated the effects on neuromuscular performance of a 6-week Optimal Load Training (OLT) and a novel modified Complex Training (MCT) (complex pairs: the same exercise using a moderate and an OL) in basketball players, in-season. Eighteen male athletes were randomly assigned to one of the protocols. Anthropometric measurements were taken to evaluate body composition. Lower- and upper-body maximum dynamic strength, countermovement jump (CMJ), standing long jump (SLJ), 10-m sprint and change of direction (COD) were also assessed. Moderate-to-large strength gains (presented as percentage change ± 90% confidence limits) were obtained for half-squat (OLT: 10.8 ± 5.3%; MCT: 17.2 ± 11.6%) and hip thrust (OLT: 23.5 ± 17.7%; MCT: 28.2 ± 19.0%). OLT athletes achieved likely small improvements in sprint (1.6 ± 1.6%) and COD (3.0 ± 3.2%). Players in the MCT attained likely moderate improvements in COD (3.0 ± 2.0%) and possibly small in SLJ (2.5 ± 4.6%). No protocol relevantly affected CMJ or body composition. An ANCOVA test revealed unclear between-group differences. In conclusion, both protocols increased basketball players’ strength without the use of heavy loads (> 85% 1RM) and without impairing sprint, CMJ and SLJ performance. These findings suggest that basketball strength and conditioning professionals may use either method to counteract strength losses during the season.  相似文献
