Abstract

The purpose of the present study was to investigate the socio-demographic and lifestyle determinants of physical activity practice, as well as the motivations for being or not being physically active in Spanish university students. A representative sample of students from a Spanish university (n = 2,051; 42.1% males; mean age 21.9, s = 4.8 years) participated in the present cross-sectional study. A questionnaire including questions regarding lifestyle, dietary habits, parents' characteristics, and physical activity habits was administered to the students. The socio-demographic and lifestyle determinants of physical activity practice were assessed using multivariable logistic regression. 68.4% of men and 48.4% of women reported to practise physical activity in the present sample. Those who practised physical activity consumed more fruits and were less likely to be smokers compared to non-physically active students. Also, physically inactive men spent more time in front of the computer and physically inactive women spent more time in front of the TV and were more likely to be frequent alcohol consumers. Maternal educational level and maternal physical activity habits were also important determinants of physical activity practice among men and women respectively. In conclusion, physically active students tended to engage in other healthy habits in the present population, suggesting the clustering of healthy or unhealthy lifestyle factors among specific subgroups.  相似文献   

Tensiomyography parameters and jumping and sprinting performance in Brazilian elite soccer players

Tensiomyography has been suggested as an indirect marker of muscle stiffness, which is associated with strength/power performance. Therefore, it is reasonable to suggest that tensiomyography parameters could be associated with power-related motor tasks. The purpose of this study was to investigate the association between tensiomyography parameters (from rectus and biceps femoris) and jumping and sprinting abilities in elite soccer players. In addition, we used tensiomyography parameters to compare the lateral symmetry between dominant and non-dominant legs. Twenty elite soccer players (age: 23.3 ± 4.8 years; height: 183.5 ± 6.6 cm; weight: 77.8 ± 7.5 kg) volunteered to participate in the study. Significant moderate negative correlations between biceps femoris displacement and contact time (r = –0.5, p = 0.03), rectus femoris displacement and contact time (r = –0.51, p = 0.02), and a significant moderate correlation between biceps femoris displacement and reactive strength index (r = 0.5, p = 0.03) were found. There were no correlations between tensiomyography parameters and power-related motor tasks. In addition, no differences in tensiomyography parameters between dominant and non-dominant legs were found. Our data suggest that tensiomyography parameters are not associated with power-related motor tasks performance in elite soccer players.  相似文献

Adding automatic evaluation to interactive virtual labs     

Gonzalo Farias  David Muñoz de la Peña  Fabio Gómez-Estern  Luis De la Torre  Carlos Sánchez  Sebastián Dormido 《Interactive Learning Environments》2016,24(7):1456-1476

Automatic evaluation is a challenging field that has been addressed by the academic community in order to reduce the assessment workload. In this work we present a new element for the authoring tool Easy Java Simulations (EJS). This element, which is named automatic evaluation element (AEE), provides automatic evaluation to virtual and remote laboratories built with EJS by using the server application Goodle grading management system (GMS). The integration of both tools entitles a professor to create interactive virtual and remote laboratories and automatically evaluate the work of their students. As a test bed two case studies are presented; a non-linear controller design virtual laboratory used in an advanced control master course and a servomechanism virtual laboratory used in an undergraduate basic control course.  相似文献   

Impact of Adding Internet Technology on Student Performance and Perception of Autonomy in Fundamentals of Electronics Course     

Carlos Andrés Rosero-Zambrano  Alba Avila  Luz Adriana Osorio  Sandra Aguirre 《Journal of Science Education and Technology》2018,27(2):177-187

The coupling of the traditional classroom instruction and a virtual learning environment (VLE) in an engineering course is critical to stimulating the learning process and to encouraging students to develop competencies outside of the classroom. This can be achieved through planned activities and the use of information and communication technologies (ICTs), resources designed to complement students’ autonomous learning needs. A quantitative analysis of students’ academic performance using final course grades was performed for a fundamentals of electronics course and we examine students’ perception of their autonomy using surveys. The students’ progress and attitudes were monitored over four consecutive semesters. The first began with the design of the intervention and the following three consisted in the implementation. The strategy was focused on the development of course competencies through autonomous learning with ICT tools presented in the VLE. Findings indicate that the students who did the activities in the VLE showed an increase in performance scores in comparison with students who did not do them. The strategy used in this study, which enhanced perceived autonomy, was associated with a positive effect on their learning process. This research shows that a technology-enhanced course supported by ICT activities can both improve academic performance and foster autonomy in students.  相似文献   

Dissemination of public health information: key tools utilised by the NECOBELAC network in Europe and Latin America     

De Castro P  Marsili D  Poltronieri E  Calderón CA 《Health information and libraries journal》2012,29(2):119-130

Background: Open Access (OA) to scientific information is an important step forward in communication patterns, yet we still need to reinforce OA principles to promote a cultural change of traditional publishing practices. The advantages of free access to scientific information are even more evident in public health where knowledge is directly associated with human wellbeing. Objectives: An OA ‘consolidation’ initiative in public health is presented to show how the involvement of people and institutions is fundamental to create awareness on OA and promote a cultural change. This initiative is developed within the project NEtwork of COllaboration Between Europe and Latin American Caribbean countries (NECOBELAC), financed by the European Commission. Methods: Three actions are envisaged: Capacity building through a flexible and sustainable training programme on scientific writing and OA publishing; creation of training tools based on semantic web technologies; development of a network of supporting institutions. Results: In 2010–2011, 23 training initiatives were performed involving 856 participants from 15 countries; topic maps on scientific publication and OA were produced; 195 institutions are included in the network. Conclusions: Cultural change in scientific dissemination practices is a long process requiring a flexible approach and strong commitment by all stakeholders.  相似文献   

Relational engagement: Proportional reasoning with bilingual Latino/a students     

Higinio Dominguez  Carlos A. LópezLeiva  Lena Licón Khisty 《Educational Studies in Mathematics》2014,85(1):143-160

In this paper, we explored how engagement developed over time during a proportional reasoning unit for a group of US bilingual Latino/a students, with particular attention to aspects of social and cultural activity that supported students’ engagement. Our findings suggest that student mathematical engagement developed primarily as a relational process characterized by students’ social relations across time, their understandings about their relationships with mathematics, and the important relations emerging across proportional reasoning ideas.  相似文献   

History of education in Brazil: the construction of a knowledge field     

José Gonçalves Gondra  Carlos Eduardo Vieira  Regina Helena Silva Simões  Claudia Engler Cury 《Paedagogica Historica: International Journal of the History of Education》2014,50(6):822-829

This article analyses the general characteristics of the construction of the field of history of education in Brazil. To do so, it highlights the existing historiography and aims to describe the process of institutionalisation of this knowledge field, which, in general terms, has been focused on the area of teacher training. Since the nineteenth century, however, it has also been possible to identify systematic historiographical efforts in Brazil that are not directly related to the school system, but rather to the teaching of and research into the history of education within Brazilian universities. The article addresses the organisation of the field, the ways in which it has been structured and the strategies of academic legitimisation employed to achieve this. These include the regular production of dissertations and doctoral theses, the publication of books and journals, academic events and the creation of research groups and scientific associations, through which research findings have found national and international circulation. This set of indicators creates conditions for an understanding of the expansion and reconfiguration of the field of history of education that began in the 1980s, as well as of the challenges this phenomenon presents to current historiography and teacher training in Brazil.  相似文献   

Are teachers’ approaches to teaching responsive to individual student variation? A two-level structural equation modeling     

Pedro Rosário  José Carlos Núñez  Guilermo Vallejo  Olímpia Paiva  António Valle  Sonia Fuentes  Ricardo Pinto 《European Journal of Psychology of Education - EJPE》2014,29(4):577-601

In the framework of teacher’s approaches to teaching, this study investigates the relationship between student-related variables (i.e., study time, class absence, domain knowledge, and homework completion), students’ approaches to learning, and teachers’ approaches to teaching using structural equation modeling (SEM) with two independent data samples. The participants were 61 biology teachers and their corresponding 1,518 high school students (12th grade). The first sample was used to fit the model, and the second sample was used to analyze the consistency of the data derived from the first sample. Using a two-level SEM analysis, we established whether the effects found at the individual level varied significantly at class level. The students’ approaches to learning were related to the teachers’ approaches to teaching as a function of the hypotheses established in the model, although the effect size was smaller than expected. However, approximately 48 % of the variance of the surface approach and 46 % of the deep approach sat at class level. At the individual level, the results of this study suggest that students’ approaches to learning significantly explain their teachers’ approaches to teaching and, thus, constitute important contextual variables. At the class level, the way students learn appears to be closely associated with class-related variables. Our data stresses the importance of promoting educational opportunities (e.g., school-based courses) for teachers to reflect upon the teaching methodologies used in class.  相似文献
