In mathematics teaching, there are constantly teachers complaining: “hey! Infuriating, this class was unable to complete the teaching plan because of the students’ difficult questions.” “ Problems endless debate, the result did not complete the task of teaching. ”And after each test or examination, there are teachers wonder: the content of the talk about the class, the practice is also practiced, each completed a teaching plan, How to test a slight change in the type of questions, students can not start, can not test good grades, how can students improve their math results? ... The reason, teachers in mathematics teaching, is generally from the analysis of teaching tasks to determine The original level of students and clear teaching objectives began, and then design teaching methods and implementation of teaching activities, and finally teaching
