Contribution: This work seeks to ascertain the validity of a remote-controlled experiment of the Physics Remote Lab in the educational context, specifically among students from engineering courses. Background: In 2012, it has been started the development of the Physics Remote Lab at the Federal University of Itajubá, Brazil, a laboratory with a collection of didactical remote-controlled experiments. For a while since then, efforts have been directed mainly to technical matters and so, many questions regarding the effectiveness of these experiments as a teaching resource have not been satisfactorily answered yet. The restrictions imposed by the pandemic have provided suitable conditions to assess the effectiveness of this kind of resource. Research Questions: There are two points to be addressed. The first refers to whether remotely controlled experiments can be regarded as a valid didactical tool. The second seeks to ascertain the effectiveness of these digital objects in a very atypical scenario. Methodology: A pretest-intervention-posttest design was chosen, with three groups that totaled 145 students from engineering courses. The groups were submitted to interventions based on a remote-controlled experiment, video analysis, and simulation on kinematics. Nonparametric statistical tests were applied to check for biased groups and to compare the results before and after the intervention. Findings: The results show that all three interventions had a significant impact on the groups and the established I-index suggests that the effects were positive in all of them, despite the peculiar circumstances regarding the pandemic. Compared to other groups, the results for the remote-controlled experiment group showed that it can be as effective as a simulation or a video analysis and the students in this group achieved a better understanding of the concepts as compared to their performance on the pretest.

计算机辅助实验（CAE）：关于远程控制实验、视频分析和运动学仿真的研究

贡献：这项工作旨在确定物理远程实验室远程控制实验在教育背景下的有效性，特别是在工程课程的学生中。背景：2012年，巴西伊塔茹巴联邦大学开始开发物理远程实验室，该实验室拥有一系列教学远程控制实验。此后一段时间，工作主要集中在技术问题上，因此，有关这些实验作为教学资源的有效性的许多问题尚未得到令人满意的解答。疫情造成的限制为评估此类资源的有效性提供了合适的条件。研究问题：有两点需要解决。第一个涉及远程控制实验是否可以被视为有效的教学工具。第二个旨在确定这些数字对象在非常非典型场景中的有效性。方法：选择了前测-干预-后测设计，分为三组，共计 145 名工程课程学生。这些小组接受基于远程控制实验、视频分析和运动学模拟的干预措施。应用非参数统计检验来检查有偏见的群体并比较干预前后的结果。研究结果：结果表明，所有三项干预措施都对这些群体产生了重大影响，并且既定的 I 指数表明，尽管大流行的情况特殊，但所有干预措施的影响都是积极的。与其他组相比，远程控制实验组的结果表明，它可以像模拟或视频分析一样有效，并且与预测试中的表现相比，该组学生对概念有了更好的理解。
