What's in It for Me? Incentives,Learning, and Completion in Massive Open Online Courses     

Todd D. Reeves  Andrew A. Tawfik  Fortunata Msilu  Irfan Şimşek 《Journal of Research on Technology in Education》2017,49(3-4):245-259

This study investigated the distribution of incentives (e.g., certificates, badges) for massive open online course (MOOC) completion, and relationships between incentives and MOOC outcomes. Participants were 779 MOOC students internationally who participated in at least 303 different MOOCs offered by at least 12 providers. MOOC participants most commonly intended to receive, and in actuality received, free and paid course certificates of completion; other incentives (e.g., digital badges, postsecondary credits) were far less common. In addition, MOOC participants' intentions to receive both free and paid certificates were consistently and positively related to perceived learning and course completion, net other factors. (Keywords: massive open online courses, MOOCs, motivation, incentives, microcredentials, certificates of completion)  相似文献   

A Cross-Age Study of the Understanding of Three Genetic Concepts: How Do They Image the Gene, DNA and Chromosome?     

Arzu Saka  Lale Cerrah  Ali Rıza Akdeniz  Alipaşa Ayas 《Journal of Science Education and Technology》2006,15(2):192-202

The study was carried out with 175 Turkish students by using drawings at different ages understanding of gene, DNA and chromosome concepts. Students from 8th, 9th, 11th grades and, science and biology student teachers were simply asked to draw the structure of gene, DNA and chromosome in a cell and also to give explanations about these three concepts. Differences in understanding between the age groups were found to be significant for the concepts of gene and DNA. None of the groups exhibit sound understanding and regardless of the age levels, students in all groups had alternative ideas about the three concepts investigated.  相似文献

用Multisim辅助《电路分析》实验   总被引：2，自引：0，他引：2  

潘正坤 《遵义师范学院学报》2003,5(4):60-61

现代电路分析与设计任务的实现越来越多地借助于计算机手段,电路分析、设计与仿真密不可分。软件的分析和仿真功能不受实验室条件的限制,学生可以用灵活的方式,对复杂的电路,用接近实际的参数来分析仿真,可以观察到波形和响应曲线。作者通过一个简单电路的分析来阐述用EDA软件Multisim仿真紧密结合理论教学的优势,弥补手工计算习题和传统电路实验的不足,增强学生分析和解决问题的能力。  相似文献
