In junior high school mathematics teaching, strengthening concept teaching is the basis of learning mathematics well, the premise of understanding mathematical knowledge, the basis of learning theorems, formulas, rules and mathematical ideas well, and the key to improving problem-solving ability. Therefore, mathematical concepts are the basis of mathematical knowledge and the carrier of mathematical thinking methods, so concept teaching is particularly important. Let's talk about the superficial understanding of concept teaching. First, create a situation, pay attention to concept introduction, and successfully teach a new concept class. Attention should be focused on creating scenarios and designing problems, so that students can learn to observe, analyze, reveal and summarize the problem scenarios created by teachers. Teachers should provide students with as much free space as possible for thinking, exploring, discovering and innovating, and help students understand the process of concept formation, development and generalization.
