The authors developed this remote experiment with the objective to study the Hooke's law through the analysis of the coil spring. The remote experiment is available in a website, where the students can manipulate and observe the educational press and confirm Hooke's statements with the output information. In addition, the students will have the opportunity to read in the website about the educational press, the physical law, and the use of the press in industrial processes. This remote experimentation exerts a force in the mechanical spring creating a deformation. In the defined point, the microcomputer will collect the data from the sensors, and it will save this data in the database. After the process execution, a graph with the data will be plotted in the website. The tests confirm that the educational press has informational potential because it returned values consistent with Hooke's law and the experiment presented repetition in all tests realized.展开更多
以来自Web of Science数据库有关体育教育主题的4 178篇文献记录为研究对象,通过CiteSpaceⅢ软件对相关数据进行分析和处理。以知识图谱的方式,梳理了体育教育研究的发文量、国家分布和主要研究期刊,以关键路径算法(Pathfinder)呈现高...以来自Web of Science数据库有关体育教育主题的4 178篇文献记录为研究对象,通过CiteSpaceⅢ软件对相关数据进行分析和处理。以知识图谱的方式,梳理了体育教育研究的发文量、国家分布和主要研究期刊,以关键路径算法(Pathfinder)呈现高产机构、高产作者与合作情况及研究焦点。本研究得出以下结论,体育教育研究的年发文数量呈波浪式增长趋势;国家分布与主要载文期刊主要集中在美国、巴西、英国等国;高产机构主要由美、英两国构成;高产作者有相当一部分领军人物为华人,且与高产机构对比发现,高产作者大部分都就职于顶尖的高产机构;符合Power Law的分布规律,这些作者与机构都有一定的倾向性研究领域。展开更多
