摘要

贡献：这项工作旨在确定物理远程实验室遥控实验在教育背景下的有效性，特别是在工程专业学生中的有效性。背景：2012 年，巴西伊塔朱巴联邦大学开始开发物理远程实验室，这是一个集合了遥控教学实验的实验室。从那时起的一段时间里，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答复。大流行病造成的限制为评估这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。第一个问题是遥控实验是否可被视为有效的教学工具。第二个问题是要确定这些数字对象在非典型情况下的有效性。实验方法：采用前测--干预--后测的设计方法，分为三组，共 145 名来自工程学课程的学生。这些小组接受了基于遥控实验、视频分析和运动学模拟的干预。采用非参数统计检验来检查各组是否存在偏差，并比较干预前后的结果。研究结果：结果表明，尽管大流行病的情况特殊，但所有三项干预措施都对各组产生了重大影响。与其他组相比，遥控实验组的结果表明，遥控实验与模拟或视频分析一样有效，与预测成绩相比，该组学生对概念的理解更透彻。

Computer-Aided Experiments (CAE): A Study Regarding a Remote-Controlled Experiment, Video Analysis, and Simulation on Kinematics

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.

期刊介绍： The IEEE Transactions on Education (ToE) publishes significant and original scholarly contributions to education in electrical and electronics engineering, computer engineering, computer science, and other fields within the scope of interest of IEEE. Contributions must address discovery, integration, and/or application of knowledge in education in these fields. Articles must support contributions and assertions with compelling evidence and provide explicit, transparent descriptions of the processes through which the evidence is collected, analyzed, and interpreted. While characteristics of compelling evidence cannot be described to address every conceivable situation, generally assessment of the work being reported must go beyond student self-report and attitudinal data.
