With the reform of college entrance examinations, knowledge of physics on the part of high school students in different places is different, and it is of great significance to study the connection between teachings of high school physics and college physics. Taking 84 sophomores as the research objects, we conducted teaching research on the connection between college physics and middle school physics through targeted teaching mode of pre-test and post-test, classroom teaching and practice questions. The study shows that enhancing formative assessment is helpful to assess students' learning and teachers' work, and improve the connection between middle school and college education of physics.
