The introduction of new courses is one of the important links for teachers to teach new textbooks, and it is also a teaching art. As the saying goes, a good beginning is half the battle. Good classroom lead-in can stimulate students' interest in learning, make students prepare lessons purposefully, and effectively guide students to concentrate their thinking, thus laying a good foundation for the whole class.

There are several common ways to effectively introduce new courses in junior middle school history teaching.

First, review the lead-in method. Review lead-in is the most commonly used guiding method in traditional history teaching. According to the logical relationship between knowledge, it looks for the connection point between old and new knowledge, and learns the new by introducing the old or reviewing the old, which has the function of connecting the preceding with the following. Although this kind of guidance is often lacking in interest, history is a course with strong time coherence. Carefully designed according to the specific teaching content, introducing new lessons by reviewing old lessons is conducive to the connection of knowledge, enabling students to understand the causal relationship of historical concepts, thus making their understanding more comprehensive. For example, when studying the history of Xia, Shang and Zhou dynasties, it would be better to guide people with the brutal rule of tyrants. Xia Jie's fatuity, the brutality of Shang and Zhou Dynasties and the autocracy of Zhou Liwang led to the demise of one dynasty and directly or indirectly promoted the establishment of a new dynasty. This kind of connection, care before and after, and natural transition makes it easy for students to transfer their previous knowledge to the classroom they are about to learn.
