Supporting computer-mediated learning: A case study in online staff development and classroom learning environment assessment     

Luis Miguel Villar Angulo  Olga María Alegre de la Rosa 《Learning Environments Research》2008,11(3):211-226

The rapid growth of online learning has led to the development of staff inservice evaluation models that are geared towards improving degree programs. Based on best practices in student online assessment, the Online Faculty Development and Classroom Learning Environment Assessment course was designed to serve the dual purpose of staff development and classroom learning environment assessment. Results of analyses showed that the course maximised the potential of online staff development for encouraging staff to reflect on Curriculum and Teaching Capacities (CTC). Implications are discussed in terms of emphasising the process of online CTC learning and incorporating perspectives to capture a comprehensive view of staff teaching attitudes and their association with student perceptions of the classroom learning environment.  相似文献   

Associations between prolonged sedentary time and breaks in sedentary time with cardiometabolic risk in 10–14-year-old children: The HAPPY study

This study examines the association between prolonged sedentary time and breaks in sedentary time with cardiometabolic risk in 10–14-year-old children. This cross-sectional design study analysed accelerometry-determined sedentary behaviour and physical activity collected over 7 days from 111 (66 girls) UK schoolchildren. Objective outcome measures included waist circumference, fasting lipids, fasting glucose, blood pressure, and cardiorespiratory fitness. Logistic regression was used for the main data analysis. After adjustment for confounders, the odds of having hypertriglyceridaemia (P = 0.03) and an increased clustered cardiometabolic risk score (P = 0.05) were significantly higher in children who engaged in more prolonged sedentary bouts per day. The number of breaks in sedentary time per day was not associated with any cardiometabolic risk factor, but longer mean duration of daily breaks in sedentary time were associated with a lower odds of having abdominal adiposity (P = 0.04) and elevated diastolic blood pressure (P = 0.01). These associations may be mediated by engagement in light activity. This study provides evidence that avoiding periods of prolonged uninterrupted sedentary time may be important for reducing cardiometabolic disease risk in children.  相似文献   

Messy but meaningful: exploring the transition to reform-based pedagogy with teachers of mathematics and coordinators in Ontario,Canada     

Daniel Jarvis 《Teacher Development》2016,20(1):18-39

The RE4MUL8 Project involved the creation of an online/mobile resource for Intermediate Division (Grade 7 and 8) teachers of mathematics. This resource showcases video documentaries of seven key mathematics topic lessons (fractions, integers, proportional reasoning, composite shapes and solids, solving equations, and, patterning and algebraic thinking), as delivered by seven teachers in Ontario, Canada who were nominated by their respective District School Boards as being, or becoming, highly effective practitioners in the area of reform-based mathematics education. As part of a qualitative case study research design, these teachers, often along with their math coordinators, were then interviewed following the lesson, and shared reflections on the lesson itself and, more generally, on their ongoing journey towards reform-based mathematics teaching. This paper reports on three major themes that emerged from these discussions, namely, problem-based learning, the reality and necessity of ‘messy time’ transition to reform-based pedagogy, and, balancing instructional planning and practices.  相似文献

Acute intraocular pressure responses to high-intensity interval-training protocols in men and women     

Jesús Vera  Beatríz Redondo  David Cárdenas  Bryon R McKay  Amador García-Ramos 《Journal of sports sciences》2019,37(7):803-809

We aimed (1) to test the acute impact of two high-intensity interval-training (HIIT) protocols differing in the level of effort on intraocular pressure (IOP) responses, and (2) to elucidate whether the IOP responses differ between men and women. Twenty-four physically active collegiate (12 men and 12 women) performed three protocols: low-fatigue HIIT (eight 30-m sprints with 60-s of rest), high-fatigue HIIT (eight 30-m sprints with 30-s of rest), and control (walking). IOP was taken at baseline, after sprints and recovery by rebound tonometry. Our data revealed an acute IOP reduction during both HIIT protocols compared to the control condition (effect size [ES]:0.81–1.65). The differences between both HIIT protocols were generally negligible (ES<0.30), however, the reduction of IOP was moderately higher for the low-fatigue HIIT protocol after the 7th (ES: 0.67) and 8th (ES: 0.74) sprints. Women showed a more prominent lowering effect on IOP during the control condition (ES: 0.42–1.02), and during the two first sprints of both HIIT protocols (ES: 0.54–1.03). These findings highlight that a time-efficient HIIT protocol may acutely reduce IOP levels, while low-fatigue HIIT protocol could be recommended since it induced a higher reduction on IOP than the high-fatigue HIIT protocol.  相似文献   

Socio‐scientific controversies and students' conceptions about scientists     

Cecília Galvão 《International Journal of Science Education》2013,35(13):1621-1633

This article discusses the results of a mainly qualitative study into possible impacts of recent controversial socio‐scientific issues on a group of Portuguese secondary school students regarding their conceptions about scientists. The 86 participants: (1) answered a questionnaire with open‐ended questions; and (2) wrote a science fiction story involving a group of scientists working on a particular situation of her/his choice. Next, semi‐structured interviews were carried out to clarify and discuss the ideas embodied in the stories and mentioned in the questionnaire. All data underwent a process of content analysis. The socio‐scientific controversies recently discussed, and the way science and scientists are depicted in the media, seem to have produced some impact on students' conceptions about scientists. Based on the results obtained, some remarks and educational implications are discussed.  相似文献   

El control de la conducta de los niños en clase     

Ildefonso Valleio García 《Infancia y Aprendizaje》2013,36(9):122-128

RESUMEN

En este artículo el autor demuestra experimentalmente la hipótesis de que la desaprobación a las conductas indeseadas del niño no consiguen reducirlas ni eliminarlas, sino que incluso pueden aumentarlas. Sin embargo con la aprobación de las conductas deseadas disminuyen notablemente las indeseadas.  相似文献
