Abstract: When college students do their homework, they often encounter some problems that are perplexing and difficult to solve. If teachers can answer questions in time, they can effectively improve the teaching outcome. Therefore, this paper puts forward the e-homework timely feedback mode based on Internet+mind map and carries out teaching practice. This mode breaks the traditional homework mode in teaching and realizes online correction and repeated feedback of homework. As an extension and expansion of mixed teaching, it can effectively realize the seamless connection between in-class teaching and extracurricular homework, and create a new teaching model that is student-centered pedagogies and problem-solving oriented.
