In the classroom, students' questioning is an important form of students' classroom participation, and it is also a display of students' active exploration, independent thinking and creation. This paper is divided into three parts: The first part introduces the background of the topic and discusses the necessity of inspiring students to ask questions in junior high school mathematics classroom teaching under the new curriculum reform. The second part, classroom teaching at home and abroad inspires students to ask questions and the support of related theories. The third part, through the questionnaire survey of junior middle school students, interviews with teachers, and case analysis of inspiring students to ask questions in junior middle school mathematics classroom teaching, discusses the main factors affecting the implementation of questioning research in junior middle school classroom teaching. It is concluded that cultivating junior high school students' problem consciousness, creating mathematics situations in various ways, paying attention to students' classroom questioning and feedback, and strengthening the effective demonstration of teachers' questioning are the keys to stimulate students' questioning in junior high school mathematics classroom teaching.
