教学实验室是本科物理课程的基础，但它们可能的学习目标是巨大的，支持任何特定目标的证据有限。在这项研究中，我们评估了不同的目标和结构的实验室对学生的批判性思维能力和对实验的看法的有效性，使用了来自100多所机构的20000多名学生的广泛的调查响应数据库。在这里，我们表明，实验室专注于发展实验技能，提高学生的批判性思维能力和实验观点相比，实验室专注于加强讲座的概念。我们进一步证明了基于技能的实验室对基于概念的实验室对学生性别和种族或民族的这些结果的积极影响。我们的分析还表明，活动，以支持学生的决策和沟通解释超过一半和三分之一的skillsbased实验室对学生的批判性思维能力和实验观点的影响，分别，而建模活动只有一个小的影响性能。
Instructional labs are fundamental to an undergraduate physics curriculum, but their possible learning goals are vast with limited evidence to support any particular goal. In this study, we evaluate the efficacy of labs with different goals and structures on students' critical thinking skills and views about experimentation, using an extensive database of survey responses from over 20 000 students at over 100 institutions. Here, we show that labs focused on developing experimentation skills improve students' critical thinking skills and experimentation views compared to labs focused on reinforcing lecture concepts. We further demonstrate the positive impacts of skills-based labs over concepts-based labs on these outcomes across students' gender and race or ethnicity. Our analysis also shows that activities to support students' decision making and communication explain over one-half and one-third of the effect of skillsbased labs on students' critical thinking skills and experimentation views, respectively, while modeling activities have only a small effect on performance.
