Abstract

In this work, we estimate the impact over five semesters of a methodology based on Just in Time Teaching in Physics for Engineering laboratory courses. The research question explored here is as follows: what is the impact of Just in Time Teaching (JiTT) implementation on student academic achievements as measured by the grades obtained by engineering students in physics laboratories? We examined the research question by statistical analysis of the grades obtained by students before and after the implementation of the JiTT strategy. The statistical analysis showed an increase in the percentage of students with grades over 4.0/5.0 upon the implementation of this strategy. A significant difference between the grades obtained before and after implementation in the Physics I and Physics II laboratories was confirmed by ANOVA (p < 0.005); in contrast, in Physics III laboratories, we observed similar grades before and after the implementation. We conclude that the implementation of JiTT improves the grade distribution over higher values, suggesting that students have better learning outcomes; more efforts are needed in Physics III laboratories to achieve a similar (or greater) increase in grades than in Physics I and II.

通过即时教学(jit)提高工科学生物理学习效果

在这项工作中，我们估计了基于工程物理实验课程实时教学方法的五个学期的影响。本文探讨的研究问题是:以工科学生在物理实验室取得的成绩衡量，jit教学的实施对学生的学业成绩有什么影响?我们通过统计分析学生在实施JiTT策略之前和之后获得的成绩来检验研究问题。统计分析表明，在实施该策略后，成绩在4.0/5.0以上的学生比例有所增加。采用方差分析(ANOVA)证实，物理一和物理二实验室在实施前和实施后取得的成绩有显著差异(p < 0.005);相比之下，在物理III实验室中，我们观察到实施前后的成绩相似。我们的结论是，JiTT的实施改善了较高值上的年级分布，这表明学生有更好的学习成果;物理三的实验室要取得与物理一和物理二相似(或更高)的成绩，需要付出更多的努力。

期刊介绍： Accounts of Chemical Research presents short, concise and critical articles offering easy-to-read overviews of basic research and applications in all areas of chemistry and biochemistry. These short reviews focus on research from the author’s own laboratory and are designed to teach the reader about a research project. In addition, Accounts of Chemical Research publishes commentaries that give an informed opinion on a current research problem. Special Issues online are devoted to a single topic of unusual activity and significance. Accounts of Chemical Research replaces the traditional article abstract with an article "Conspectus." These entries synopsize the research affording the reader a closer look at the content and significance of an article. Through this provision of a more detailed description of the article contents, the Conspectus enhances the article's discoverability by search engines and the exposure for the research.
