The Scientific Teaching (ST) pedagogical framework provides various approaches for science instructors to teach in a way that more closely emulates how science is practiced by actively and inclusively engaging students in their own learning and by making instructional decisions based on student performance data. Fully understanding the impact of ST requires having mechanisms to quantify its implementation. While many useful instruments exist to document teaching practices, these instruments only partially align with the range of practices specified by ST, as described in a recently published taxonomy. Here, we describe the development, validation, and implementation of the Measurement Instrument for Scientific Teaching (MIST), a survey derived from the ST taxonomy and designed to gauge the frequencies of ST practices in undergraduate science courses. MIST showed acceptable validity and reliability based on results from 7767 students in 87 courses at nine institutions. We used factor analyses to identify eight subcategories of ST practices and used these categories to develop a short version of the instrument amenable to joint administration with other research instruments. We further discuss how MIST can be used by instructors, departments, researchers, and professional development programs to quantify and track changes in ST practices.
科学教学(ST)教学框架为科学教师提供了多种方法,以更紧密地模拟科学实践的方式进行教学,积极并包容地让学生参与自己的学习,并根据学生表现数据做出教学决策。要充分了解 ST 的影响,需要有量化其实施的机制。虽然有许多有用的工具可以记录教学实践,但这些工具仅部分符合 ST 所规定的实践范围,如最近发表的分类法所述。在这里,我们描述了科学教学测量工具(MIST)的开发、验证和实施,这是一个源自 ST 分类法的调查,旨在衡量本科科学课程中 ST 实践的频率。MIST 在来自 9 个机构的 87 门课程的 7767 名学生的结果基础上表现出了可接受的有效性和可靠性。我们使用因子分析来确定 ST 实践的八个亚类,并使用这些类别来开发一个简短的工具版本,便于与其他研究工具一起管理。我们还进一步讨论了 MIST 如何被教师、系、研究人员和专业发展计划用来量化和跟踪 ST 实践的变化。
