Research-based Evaluation and Improvement of Physics Instructions

发展了科学的数据分析和评价方法，以改进物理课堂教学。在大学一年级和高中生的物理入门课程中都实施了同伴指导。实验前的测试数据和同伴教学效率的数据被用来定量分析学生对物理的理解和学生讨论的有效性。我们的结果表明，通过这些科学的定量分析和评价讲课的方法，建立一个改进物理讲课的循环是可能的。

Scientific methods of data analysis and evaluation for improving physics lectures have been developed. Peer Instruction has been implemented in the introductory physics course for freshmen as well as for high-school students. Data obtained from the pre-post tests and from the Peer-Instruction Efficiency have been used for quantitative analyses of students’ understanding of physics and the effectiveness of discussion among students. Our results suggest that it is possible to establish a loop of improving physics lectures by these scientific methods of quantitative analysis and evaluation of lectures.
