The invention can be applied to middle school physics classroom teaching, middle school textbook compilation and solving of actual physics problems, can accurately identify hand-drawn circuit diagrams, standardize the drawn components and print them on the screen, which is convenient and practical.

Description

technical field [0001] The invention relates to the field of middle school physics teaching, in particular to a circuit teaching system and method based on pen interaction. Background technique [0002] In middle school physics classroom teaching activities, the teaching of circuit problems is both important and difficult. Nowadays, the traditional teaching method of teachers drawing circuit diagrams directly with chalk on the blackboard is usually used. Lecture content to complete the learning of circuit knowledge or understanding of circuit topics. However, in actual teaching activities, the teaching time of each class is limited. When teaching new circuit knowledge, middle school physics teachers need to temporarily draw different circuit diagrams according to the different knowledge points. Temporarily draw different circuit diagrams, so that teachers need to draw a large number of different circuit diagrams within a class. Due to time constraints, there are problems s...

Problems solved by technology

However, in actual teaching activities, the teaching time of each class is limited. When teaching new circuit knowledge, middle school physics teachers need to temporarily draw different circuit diagrams according to the different knowledge points. Temporarily draw different circuit diagrams, so that teachers need to draw a large number of different circuit diagrams within a class

Due to time constraints, there are problems such as inaccurate drawing of components, ambiguity in related data of components, wrong connection of wires, etc., which is not conducive to the correct understanding of circuit diagrams for middle school students, and the teaching effect of classroom teaching knowledge is greatly reduced
