Abstract: Data structure course is a basic course of computer science. In the teaching process, students feel that the content is too abstract and difficult to learn. Promoting students'practice through online question banks can effectively evaluate their learning status, improve their learning efficiency, and expand their learning depth. Based on the teaching experiences, a question bank suitable for hybrid teaching mode is constructed, and the teaching mode is designed. The results indicate that the online question bank can improve the convenience of answering questions and the flexibility of test composition, which is conducive to efficient teaching feedback and interaction, optimize teaching content. Through the practice of online question bank, students can understand the knowledge better and improve their comprehensive ability, which is of great help to improve their grades.
