Smart classroom is a classroom answering system specially designed for college students. Students only need to use the mobile phone client to answer questions in class, which can improve the active atmosphere in class.
Smart classroom is a new classroom form with deep integration of information technology and subject teaching. However, at present, classroom interaction is mostly the interaction of shallow cognitive input such as answering questions, praising and uploading homework. Lack of debate, games, reflection and cooperative problem-solving can promote students' interaction in the deep processing of knowledge, while the superficial "positive" and "active" interaction can not promote the development of students' thinking ability and creativity.
