This thesis researches the basic principles of junior high school biology scene teaching collection. Biology is an important subject in the junior high school biology classroom. In the junior high school classroom, when encountering obscure knowledge points, it is inevitable to use situational teaching. Situational teaching is conducive to stimulating students' interest in learning and improving students' thinking and understanding. Help students correctly understand emotions. In the context of teaching, the collection of teaching materials is indispensable. Then, when collecting teaching materials, how should teachers observe those principles? This thesis takes the "Life of Angiosperm" in the junior high school biology and human education edition as an example to study and discuss the basic principles of teaching material collection. <br>The basic principles of the collection of teaching materials include: individuality, economy, safety, effectiveness, sharing and other principles. Through research, explore the basic principles of situational teaching material collection, hoping to enable teachers to have a further understanding of the collection of situational teaching materials, and hope that in the use of situational teaching materials, teachers can better introduce students into situational teaching, better Broaden students’ horizons, stimulate interest in learning, and improve learning efficiency.

This paper studies the basic principles of biology situation teaching collection in junior high school.

Through the research, this paper discusses the basic principles of situational teaching materials collection, hoping to make teachers have a further understanding of the collection of situational teaching materials. At the same time, it is hoped that in the application of situational teaching materials, teachers can better introduce students into situational teaching, better broaden students' horizons, stimulate learning interest and improve learning efficiency.<br>
