The teaching methods of the computer curriculum must look for a new way in higher vocational education. The case-based teaching approach plays an important role in the computer teaching and has the advantage compared to the traditional teaching method. Business Website Development is a course which emphasizes the practice and application of making business websites. The traditional teaching approach is not conductive to reflect the function of double subjects that are the teacher and the student. The paper presented the application of project-driven case-based teaching approach in the curriculum of business website development. The approach mainly included the following steps: actual project selection, case task partitioning, scenario designing, question proposed, problem solving in group and communication evaluation. This is good for reforming traditional infiltration teaching mode, motivating students' participation and communication initiative, enhancing teachers working level, and students' abilities of analyzing and solving problems. In the process of case teaching, it can guide the students to study and fuel the students' initiative of learning by project-driven case-based teaching.
