论文摘要
有多种教学方法来促进本科物理课程中的协作和个人工作。但是,很少有教育研究试图了解学生如何通过需要数学建模和实验的开放式活动来学习和应用新知识,这些活动集中在环境问题上。在这项工作中,我们提出了一个新型的家庭实验,以模拟温度反转下颗粒物的动力学,并将其模拟为抑制谐波运动。在设计和开发实验后,二十六名第一年的学生参加了STEM专业的学生,回答了六个定性问题。这些问题有助于分析学生关于其物理主题学习过程及其应用的认识论信念。结果表明,这种开放式实验可以促进学生对物理现象的理解。此外,该实验表明,它可以通过使学生有机会寻找不同的知识来源并成为自学者,而不是将教授视为认识论权威,从而帮助物理教授促进学生认识论发展。最后,学生将这项活动描述为一种积极的经历,帮助他们实现了在环境不同情况下应用物理主题的替代方法。
There are diverse teaching methodologies to promote both collaborative and individual work in undergraduate physics courses. However, few educational studies seek to understand how students learn and apply new knowledge through open-ended activities that require mathematical modeling and experimentation focused on environmental problems. In this work, we propose a novel home experiment to simulate the dynamics of a particulate under temperature inversion and model it as damped harmonic motion. Twenty six first year students enrolled in STEM majors answered six qualitative questions after designing and developing the experiment. These questions helped analyze the students epistemological beliefs about their learning process of physics topics and its applications. Results showed that this type of open-ended experiments could facilitate the students understanding of physics phenomena. In addition, this experiment showed that it could help physics professors to promote students epistemological development by giving their students the opportunity to search for different sources of knowledge and becoming self-learners instead of looking at the professor as the epistemological authority. At the end, students described this activity as a positive experience that helped them realize alternative ways to apply physics topics in different contexts of their environment.
