UNLABELLED Though widely considered to reduce physical exposures and increase exposure variation, there is limited evidence that rotating between tasks is effective in reducing the risk of work-related musculoskeletal disorders (WMSDs). The purpose of this study was to assess the effects of rotation, specifically focusing on rotation frequency and task(More)
1 Second through fifth authors are listed in an alphabetical order. Abstract In this paper, we describe a ludic simulation designed for middle school space science and examine its use to support students' learning and motivation. The participants were 383 sixth graders and 447 seventh graders. The findings of this study showed that sixth-and seventh-graders(More)
Though widely considered to reduce the risk of work-related musculoskeletal disorders, there is limited evidence suggesting that rotating between tasks is effective in doing so. The purpose of the current study was to quantify the effects of rotation and parameters of rotation (frequency and task order) on muscle fatigue and performance. This was done using(More)
Algorithm visualizations (AVs) have become a popular teaching aid in classes on algorithms and data structures. The AlgoViz Project attempts to provide an online venue for educators, students, developers,researchers, and other AV users. The Project is comprised of two websites. The first, the AlgoViz Portal, provides two major informational resources: an AV(More)
