许多研究表明，学生在运动学中对图形的理解存在困难。一些作者认为，我们可以使用不同的教学策略，以减少这些困难。基于这些研究，我们使用教育机器人技术开发并应用了一个教学序列，以教授恒速维度运动的图形分析。在这项工作中，我们将通过学生在活动前后进行的测试中获得的分数来分析一个序列的结果。我们使用Wilcoxon测试来评估学生在前测试和后测试中的分数之间是否存在统计差异，我们还分析了学生对每个问题的回答。我们确定了存在的统计差异的学生在测试中获得的分数和进化的可能性，在理解使用图形的分析的动作。
Many researches show that students have difficulties in understanding graphics in kinematics. Some authors argue that we can use different instructional strategies to reduce these difficulties. Based on these studies, we developed and applied a didactic sequence using educational robotics to teach graphic analysis in movements in a dimension with constant speed. In this work, we will analyse the results of a sequence through the scores obtained by students in the tests applied before and after the activities. We used the Wilcoxon test to assess the existence of statistical differences between the scores of students in the pre- and post-tests, and we also analyse students’ answers to each question. We identified the existence of a statistical difference between the scores obtained by the students in the tests and the possibility of evolution in the understanding of the use of graphs for the analysis of the movements.
