2. Abandon the old teaching concept and establish a brand-new teaching concept. In teaching, I changed the protagonist of previous classroom teaching: I made up a "script" for myself, told what I wanted to talk about, and then performed it in the forum to instill knowledge in students. Now, it is to compile a "script" for students, create a learning situation for students, let students play the leading role in class, perform deduction under the guidance of teachers, and acquire knowledge independently and cooperatively.
3. Facts have proved that the implementation of this teaching concept has fundamentally changed the boring learning mode that teachers tell students that there is no interaction between teachers and students, greatly improved the enthusiasm of students to participate in learning, and the learning effect is self-evident. For example, in the teaching of "rational number addition and subtraction algorithm", the conventional teaching method is "walk a few meters east and west, and finally walk a few meters east or west, and then learn the law of rational number subtraction into addition, and finally calculate according to the law" to summarize the law of rational number addition, and everyone knows very well that the law of rational number addition in textbooks is very complicated and difficult for students who have just entered junior high school. Determining the absolute value of sum is divided into adding or subtracting the absolute values of two addends. Students here have several difficulties:
