Taking voltage measurement as an example, this paper explores the effective connection between university physics experiment teaching and secondary school physics. While strengthening the basic experiment teaching, it fully utilizes the secondary school physics foundation that students already have, appropriately raises the starting point of the teaching content, adds design-oriented experiments, and opens up comprehensive experiments. This enhances students' interest in learning physics experiments and guides them to consciously think scientifically about the methods of physics experiments. It cultivates students' scientific thinking and innovative consciousness, and lays a favorable foundation for training innovative composite talents with a broad interdisciplinary background under the new engineering context.
