开放式物理实验中的能动感、性别与学生感知
Sense of agency, gender, and students' perception in open-ended physics labs
摘要：
教学物理实验室是许多STEM专业的关键节点，以发展对科学实验的理解。学生可以获得有用的实验技能，并成长为科学家的身份。然而，许多传统教学的实验室并不一定在他们的课程中涉及真实的物理实验功能。最近的研究呼吁改革本科实验室，在学习过程中纳入更多的学生代理和选择。在我们的机构，我们已经采取了开放式的实验室教学在物理导论课程。通过使用改革后的课程，提供更高的学生代理，我们分析了大约100名学生在介绍级实验室课程，以检查他们对开放式物理实验室的看法。在学期开始和结束之间，我们发现学生对实验室活动所提供的代理的看法在统计上有显著的变化。我们还检查了学生对“你最喜欢哪个实验单元，为什么？”".分析显示，大部分学生更喜欢Project Lab，它具有最高的学生代理，编码分析显示，“自由”是学生选择Project Lab的最常见原因。最后，我们还检查了学生的意见，跨性别和发现没有显着的性别影响学生的代理感。
英文摘要：
Instructional physics labs are critical junctures for many STEM majors to develop an understanding of experimentation in the sciences. Students can acquire useful experimental skills and grow their identities as scientists. However, many traditionally-instructed labs do not necessarily involve authentic physics experimentation features in their curricula. Recent research calls for a reformation in undergraduate labs to incorporate more student agency and choice in the learning processes. In our institution, we have adopted open-ended lab teaching in the introductory physics courses. By using reformed curricula that provide higher student agency, we analyzed approximately 100 students in the introductory-level lab courses to examine their views towards the open-ended physics labs. Between the start and the end of the semester, we found a statistically significant shift in students' perceptions about the agency afforded in lab activities. We also examined students' responses to "Which lab unit was your favorite and why?". The analysis showed that majority of the students preferred Project Lab, which had the highest student agency and coding analysis showed that "freedom" was the most frequent response for students' reason for picking Project Lab. Finally, we also examined student views across gender and found no significant gender effect on students' sense of agency.
