验证我们所知道的:理解物理学实验室中有问题的研究实践

Confirming what we know: Understanding questionable research practices in intro physics labs

Martin M. Stein, Emily M. Smith, N. G. Holmes

摘要:

许多机构正在改变他们的入门物理实验室的重点,从验证物理内容转向教授学生科学的技能和性质。随着教学的变化,学生在实验室的方法和行为也会发生变化。在这项研究中,我们评估了学生的实验笔记,从早期的活动,在实验为重点的实验课程。我们发现,大约30%的学生团体(来自三个机构的107个团体)在他们的实验室笔记中记录了有问题的研究实践,例如对结果的主观解释或操纵设备和数据。这些实践中的绝大多数都与验证性目标有关,我们怀疑这些目标源于学生之前对验证实验室的接触。我们提出了以实验为重点的实验室,以更好地让学生在负责任的研究和真实的科学实践行为的方式。

英文摘要:

Many institutions are changing the focus of their introductory physics labs from verifying physics content towards teaching students about the skills and nature of science. As instruction shifts, so too will the ways students approach and behave in the labs. In this study, we evaluated students' lab notes from an early activity in an experimentation-focused lab course. We found that about 30% of student groups (out of 107 groups at three institutions) recorded questionable research practices in their lab notes, such as subjective interpretations of results or manipulating equipment and data. The large majority of these practices were associated with confirmatory goals, which we suspect stem from students' prior exposure to verification labs. We propose ways for experimentation-focused labs to better engage students in the responsible conduct of research and authentic scientific practice.
