ABSTRACT

The aims of this study were to identify profiles of sedentary behaviour (SB) patterns, based on leisure-time self-reported SB modalities (screen, educative, social, and relaxing) and to evaluate changes in these profiles over 2 years among Spanish youth aged 8–18 years. Latent profile analysis (LPA), a data-driven analytic approach, was used to identify groups of boys and girls (n = 1553; 48% girls; mean±SD age: 12.56 ± 2.49 y) with distinct SB profiles using the SB modalities (time/d) as input variables. Latent transition analysis, an extension of LPA that uses longitudinal data, was used to analyse 2-year changes in these profiles. At baseline, four and three SB profiles were found among boys (labelled: screen, educative, social, and relaxing) and girls (labelled: screen/social, educative, and relaxing), respectively. Overall, more girls (range: 48%-67%) had the same profile over time, than boys (40%-52%). Participants with a screen or relaxing SB profile at baseline were more likely to have an educative profile after 2 years. Youth with a social and an educative SB profile at baseline were more likely to transition to profiles characterized by higher screen and social SB, respectively. Using a novel and person-centered approach, this study identified gender-specific SB profiles that were moderately stable over time.  相似文献   

Predicting transition and adjustment to college: biomedical and behavioral science aspirants’ and minority students’ first year of college

The purpose of this study is to explore key factors that impact the college transition of aspiring underrepresented minority students in the biomedical and behavioral sciences, in comparison with White, Asian students and non-science minority students. We examined successful management of the academic environment and sense of belonging during the first college year. Longitudinal data were derived from the Higher Education Research Institute’s (HERI) 2004 Cooperative Institutional Research Program (CIRP) Freshman Survey and the 2005 Your First College Year (YFCY) Survey. Using a reformulation of the integration model (Nora, Barlow, and Crisp, 2005), we find concerns about college financing, negotiating family support and responsibility, and campus racial dynamics (perceived and behavioral) affect student adjustment and sense of integration in the first year. This study was made possible by the support of the National Institute of General Medical Sciences, NIH Grant Number 1 RO1 GMO71968-01.

Paulo Freire’s ideas as an alternative to higher education neo-liberal reforms in Latin America     

Oscar Espinoza 《Journal of moral education》2017,46(4):435-448

This article examines the principal arguments found in the work of Paulo Freire concerning policy and ethics in the field of higher education in Latin America. It critically analyzes the university reform in Latin America dominated by the thought and practice promoted by various international financial institutions (such as the World Bank and the Inter-American Development Bank [IDB]) beginning in the 1980s and then looks at the feasibility of an alternative Freirian view. The work of Paulo Freire celebrated the liberating role that public university education should play in the training of citizens and professionals, that is with a critical and ethical conscience, committed to the needs of the locality, region and the world. All this is in clear opposition to what has happened to Latin American universities, influenced by neo-liberal reforms over the last decades.  相似文献

Validation of the Instructional Materials Motivation Survey (IMMS) in a self‐directed instructional setting aimed at working with technology          下载免费PDF全文

The ARCS Model of Motivational Design has been used myriad times to design motivational instructions that focus on attention, relevance, confidence and satisfaction in order to motivate students. The Instructional Materials Motivation Survey (IMMS) is a 36‐item situational measure of people's reactions to instructional materials in the light of the ARCS model. Although the IMMS has been used often, both as a pretest and a posttest tool serving as either a motivational needs assessment prior to instruction or a measure of people's reactions to instructional materials afterward, the IMMS so far has not been validated extensively, taking statistical and theoretical aspects of the survey into account. This paper describes such an extensive validation study, for which the IMMS was used in a self‐directed instructional setting aimed at working with technology (a cellular telephone). Results of structural equation modeling show that the IMMS can be reduced to 12 items. This Reduced Instructional Materials Motivation Survey IMMS (RIMMS) is preferred over the original IMMS. The parsimonious RIMMS measures the four constructs attention, relevance, confidence and satisfaction of the ARCS model well, and reflects its conditional nature.  相似文献   

The Use of Digital Educational Technology and Third Spaces with Foreign-Born Latinos     

Oscar Guerra-Nunez 《Journal of Latinos & Education》2017,16(4):323-337

This article addresses the concept of educational third spaces that move beyond the paternalistic concept of a teacher as a font of knowledge filling the empty vessels of the students’ minds, especially for foreign-born Latino (FBL) students. These students often struggle and lag behind their native-born peers as they master the new language of instruction while acculturating to a new and challenging environment. However, as digital natives, current elementary FBL students have the potential to empower themselves via the use of educational technology. In organic third spaces, educational technology can foster active learning and personal empowerment.  相似文献

Neoliberalism,education and the integration of ICT in schools. A critical reading     

Oscar Moltó Egea 《Technology, Pedagogy and Education》2014,23(2):267-283

This article explores a contemporary perspective of education that aims to radically re-construct schools through the integration of information and communication technologies (ICT). Through the analysis of key texts produced by the Organisation for Economic Co-operation and Development, leading ICT industries, and international educational researchers, the article looks at the apparently neutral and desirable regime of truth surrounding education, where concrete problems are created and certain solutions provided. The findings discuss how the integration of ICT in schools is embedded in a perspective of education based on: new modalities of soft government, the centrality of a self-regulated and entrepreneur learner, and the representation of schools as flexible, autonomous and non-hierarchical environments organised around non-standardised modalities of public ‘accountability’.  相似文献   

Effects of Individualized Instruction on Control Expectancy: A Field Test     

John E. Roueche  Dr. Oscar G. Mink  Michael L. Abbott 《Community College Journal of Research & Practice》2013,37(2):111-118

Abstract

This study was conducted in order to determine whether or not one semester of individualized instruction is enough time to create in students an increased sense of being able to control payoffs in life and to lead students to develop a more realistic appraisal of their ability to control payoffs in an academic environment. Paradoxically, the converse may occur. When first confronted with a success-oriented instructional process and opportunities for self-pacing, students with failure histories may become more external, anxious, or uncertain. In order to examine these notions, a sample of 126 educationally deficient students who were beginning their first semester of study in a community college were selected from 18 different sections of math, English, and history and tested twice—once at the beginning of the term and again late in the term just prior to finals.  相似文献
