摘要:

我们报告的结果,从一项研究,旨在确定本科生的意见之间的联系,实验物理和他们在实验室课程的多周项目的参与。通过问卷调查和访谈,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点。我们专注于18项活动,包括维护实验室笔记本,制造零件和寻求他人的帮助。受访者认为,与项目执行相关的活动是实验物理实践的固有内容,因为这些活动在受访者自己的项目中普遍存在。装配为导向的活动被确定为有条件的功能实验的基础上项目之间的差异,受访者归因于项目资源的变化。人际交往活动也被视为实验的条件特征,取决于一个人作为新手或专家的地位。我们的研究结果表明,学生对实验物理的看法是由自己的项目的第一手经验和他人的二手经验形成的。

英文摘要:

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.
