Teaching Design of Senior High School Physical Logic Gate Circuit

In the section on “Logic Circuit” in senior high school physics, both textbooks and existing teaching research on this aspect are more focused on the principle analysis of logic circuit structure. Although a few studies involve the making of relevant teaching instruments, the layout and wiring of the device are not standardized, and its operational compatibility is low, so students do not have a comprehensive understanding of this aspect of knowledge. In order to solve this problem, I use the relevant knowledge of electronic technology to make a simple “AND” gate circuit to assist the explanation of the logic circuit, the effect of teaching and demonstration is good. In the meantime, it also provides a kind of idea of self-made teaching instruments for teachers when explaining the relevant content.
