Undergraduate research experience is the process where undergraduates contribute to the development of a subject field through their inquiry-based learning (IBL). IBL is a student-centered learning strategy. Students work as professional scientists do, through inquiry. This article presents approaches to IBL and practices of an instructor from China for strengthening and facilitating IBL in geographical information science (GIS). Two paths were proposed for the development of the students on the basis of four modes of IBL. The practical experience was introduced in two parts: course design and IBL tool development for classroom teaching, and undergraduate mentoring outside of the classroom.
