论文摘要
我们报告了一项研究的结果，旨在确定本科生对实验物理学的看法与他们参与实验室课程的多周项目之间的联系。使用调查和访谈，我们探讨了学生是否认为特定的课堂活动是实验物理实践的特征。我们专注于18种活动，包括维护实验室笔记本，制造零件以及向其他人寻求帮助。受访者将与项目执行相关的活动确定为基于受访者自己项目中这些活动的高流行率的实验物理实践的内在性。基于项目之间的差异，面向制造的活动被确定为实验的条件特征，这归因于项目资源的差异。人际活动也被视为实验的条件特征，取决于一个人的地位或专家的地位。我们的发现表明，学生对实验物理学的看法是由自己项目的亲身经历和其他人的二手经历所塑造的。
We report results from a study designed to identify links between undergraduate students' views about experimental physics and their engagement in multiweek projects in lab courses. Using surveys and interviews, we explored whether students perceived particular classroom activities to be features of experimental physics practice. We focused on 18 activities, including maintaining lab notebooks, fabricating parts, and asking others for help. Interviewees identified activities related to project execution as intrinsic to experimental physics practice based on high prevalence of those activities in interviewees' own projects. Fabrication-oriented activities were identified as conditional features of experimentation based on differences between projects, which interviewees attributed to variations in project resources. Interpersonal activities were also viewed as conditional features of experimentation, dependent upon one's status as novice or expert. Our findings suggest that students' views about experimental physics are shaped by firsthand experiences of their own projects and secondhand experiences of those of others.
