Abstract: Geochemistry is one of the pillar subjects of earth science. It has become an urgent task to strengthen the geochemical practical ability cultivation of undergraduates majoring in geology. Based on the situation of weak chemistry foundation and weak practice teaching of geochemistry course for college students majoring in earth science, this paper discusses the ways and methods to increase practices of geochemistry course. The methods include using small class teaching, geochemistry case teaching and other means to strengthen the classroom practice teaching; increasing extra-curricular practice, experiments, participation in scientific research projects and other methods to strengthen extra-curricular experiments and practices; improving the proportion of practice ability in the assessment, and so on. The purpose is to promote the comprehensive improvement of the practical ability of the undergraduates majoring in geochemistry.
