Through consulting papers and related books, I found that scholars have given "large unit teaching" different connotations based on their own perspectives and positions (such as the position of curriculum development and the position of teaching design), which all illustrate the importance of implementing literacy goals.

In my opinion, large-unit teaching is a teaching process that takes units as learning units, considers, designs and organizes the implementation of teaching contents around a certain theme or activity (big concept, big task and big project) according to curriculum standards.

The purpose is to promote the structuring of teaching content and construct the overall consciousness of teaching, so as to achieve "the whole is greater than the sum of parts", improve teaching efficiency and implement the core literacy of the subject.
