In this study, we describe participant characteristics, conversation content, and program success of an online mentoring program for northern Canadian youth. We investigate the associations between demographics and program success. The profiles and conversations of students and mentors that participated in the program between 2009 and 2013 were analyzed. Students were categorized into two groups (high and low engagement) based on the number of words written to their mentors. The high group contained proportionally more urban than rural students and equal proportions of Aboriginal and non-Aboriginal students, while the low group contained equal numbers of rural and urban students and proportionally more Aboriginal than non-Aboriginal students. This study provides valuable information on the use of online mentoring in northern communities. 相似文献

Popularity of videos for classroom instruction has increased over the years due to affordability and user-friendliness of today’s digital video cameras. This prevalence has led to an increase in flipped, K-12 classrooms countrywide. However, quantitative data establishing the appropriate video length to foster authentic learning is limited, particularly in middle-level classrooms. We focus on this aspect of video technology in two flipped science classrooms at the middle school level to determine the optimal video length to enable learning, increase retention and support student motivation. Our results indicate that while assessments directly following short videos were slightly higher, these findings were not significantly different from scores following longer videos. While short-term retention of material did not seem to be influenced by video length, longer-term retention for males and students with learning disabilities was higher following short videos compared to long as assessed on summative assessments. Students self-report that they were more engaged, had enhanced focus, and had a perceived higher retention of content following shorter videos. This study has important implications for student learning, application of content, and the development of critical thinking skills. This is particularly paramount in an era where content knowledge is just a search engine away. 相似文献

Getting the Most From Your Interactive Whiteboard Investment: Three Guiding Principles for Designing Effective Professional Development 总被引:1,自引:0,他引:1
Josh DeSantis 《Clearing house (Menasha, Wis.)》2013,86(2):51-55
The adoption of interactive whiteboards (IWB) in many schools outpaced the delivery of adequate professional development on their use. Many teachers receive IWBs without adequate training on methods to use the technology to improve their instruction. Consequently, IWBs remain an underutilized resource in many classrooms. Teachers who are given IWBs require purposeful, scaffolded, and sustained professional development to maximize the IWB's potential. This article identifies three promising professional development practices for teaching educators how to use IWBs effectively. The literature describing effective technology professional development suggests it should (1) build efficacy by scaffolding the instruction of new tasks, (2) establish long-term collaborative partnerships among teachers, and (3) include positive supervision that encourages teacher self-reflection and measures student engagement with digital media using the IWB. Professional-development designers can increase the effectiveness of their instruction by incorporating these principles into their training. 相似文献

The recent next generation science standards in the United States have emphasized learning about complex systems as a core feature of science learning. Over the past 15 years, a number of educational tools and theories have been investigated to help students learn about complex systems; but surprisingly, little research has been devoted to identifying the supports that teachers need to teach about complex systems in the classroom. In this paper, we aim to address this gap in the literature. We describe a 2-year professional development study in which we gathered data on teachers’ abilities and perceptions regarding the delivery of computer-supported complex systems curricula. We present results across the 2 years of the project and demonstrate the need for particular instructional supports to improve implementation efforts, including providing differentiated opportunities to build expertise and addressing teacher beliefs about whether computational-model construction belongs in the science classroom. Results from students’ classroom experiences and learning over the 2 years are offered to further illustrate the impact of these instructional supports. 相似文献

This study compared accuracy of energy expenditure (EE) prediction models from accelerometer data collected in structured and simulated free-living settings. Twenty-four adults (mean age 45.8 years, 50% female) performed two sessions of 11 to 21 activities, wearing four ActiGraph GT9X Link activity monitors (right hip, ankle, both wrists) and a metabolic analyzer (EE criterion). Visit 1 (V1) involved structured, 5-min activities dictated by researchers; Visit 2 (V2) allowed participants activity choice and duration (simulated free-living). EE prediction models were developed incorporating data from one setting (V1/V2; V2/V2) or both settings (V1V2/V2). The V1V2/V2 method had the lowest root mean square error (RMSE) for EE prediction (1.04–1.23 vs. 1.10–1.34 METs for V1/V2, V2/V2), and the ankle-worn accelerometer had the lowest RMSE of all accelerometers (1.04–1.18 vs. 1.17–1.34 METs for other placements). The ankle-worn accelerometer and associated EE prediction models developed using data from both structured and simulated free-living settings should be considered for optimal EE prediction accuracy. 相似文献
