在力学导论中实施和评估计算建模

Implementing and assessing computational modeling in introductory mechanics

Marcos D. Caballero, Matthew A. Kohlmyer, Michael F. Schatz

摘要:

学习物理学入门课程的学生很少接触计算建模。在佐治亚理工学院的一个学期的大型讲座介绍基于微积分的力学课程中,学生们学会了使用VPython编程环境解决物理问题。在本学期,1357名学生在这门课程解决了一套十四个计算建模家庭作业的问题,使用在线商业课程管理系统。他们的熟练程度与计算建模进行了评估,在监考环境中使用一种新的中心力问题。大部分学生(60.4%)成功完成了评估。对学生提交的错误程序的分析表明,一小部分学生的错误解释了为什么大多数程序失败。我们讨论了计算建模作业和评估的设计和实施,从评估的结果和在STEM入门课程的计算建模教学的影响。

英文摘要:

Students taking introductory physics are rarely exposed to computational modeling. In a one-semester large lecture introductory calculus-based mechanics course at Georgia Tech, students learned to solve physics problems using the VPython programming environment. During the term 1357 students in this course solved a suite of fourteen computational modeling homework questions delivered using an online commercial course management system. Their proficiency with computational modeling was evaluated in a proctored environment using a novel central force problem. The majority of students (60.4%) successfully completed the evaluation. Analysis of erroneous student-submitted programs indicated that a small set of student errors explained why most programs failed. We discuss the design and implementation of the computational modeling homework and evaluation, the results from the evaluation and the implications for instruction in computational modeling in introductory STEM courses.
