标题： Peer Influence on Physics Self-Efficacy and Grades: A comparative study of students in an introductory calculus-based course who typically worked alone or in groups before and during the pandemic

摘要： 与同学进行有意义的合作，无论是在课堂内还是课堂外，都能显著增强学生对物理和其他STEM学科的理解。 我们分析了通常独自工作与与同学合作的学生的特征，在基于微积分的入门物理课程中，比较了疫情前的传统面对面课程与疫情期间基于Zoom的课程。 我们通过考虑学生的先前学术准备、他们的物理成绩和物理自我效能感，以及他们对同伴合作对其物理自我效能感的有效性的看法来讨论我们的发现。 我们还将我们的结果与第一学期基于代数的入门物理课程进行了比较。 显示英文摘要

摘要： Engaging in meaningful collaborations with peers, both inside and outside the classroom, can greatly enhance students' understanding of physics and other STEM disciplines. We analyzed the characteristics of women and men who typically worked alone versus those who collaborated with peers in a calculus-based introductory physics course comparing pre pandemic traditional in-person classes to Zoom based pandemic classes. We discuss our findings by considering students' prior academic preparation, their physics grades and physics self-efficacy, as well as their perceptions of how effective peer collaboration is for their physics self-efficacy. We also compared our results to the first-semester algebra-based introductory physics course.
