Abstract: To improve undergraduates' practical ability during the teaching of geophysics, the thinking and exploration of how to teach will be carried out from the following four aspects. First of all, we need stimulate their learning interest. The MATLAB can be linked with PPT in the way of "fast, easy and intuitive" through PPT hyperlinks to get the numerical calculation and graphic display of a complex problem, which will increase students' interest in learning and curiosity in solving problems. To improve students' programming ability, some easy geophysical problems are selected and the students are encouraged to participate in the programming. To make full use of extracurricular activities, teachers can let students to participate in programming to carry out inversion and simulation of stratigraphic parameters using real geophysical data. This will further train students' ability of independent work and programming, and improve their comprehensive quality. In the fieldwork, students are organized to design the experimental scheme and principles by themselves, appropriate instruments are needed to be selected to organize the measurement of geophysical parameters. This cultivates students' practical ability and teamwork cooperation, which achieve the teaching goal of improving students' ability in solving practical problems.

Key words: Geophysics, Practical ability, MATLAB, Numerical simulation
