新课程改革背景下,初中数学教学呈现出了许多亮点,取得了一系列令人可喜的成绩。在长期的教学实践过程中,越来越多的初中数学教师逐渐改变了传统的教学思维和模式,开始与新的实际情况相结合,探索出了多样化的教学方法。其中,对学生逆向思维培养成为众多一线教师关注和思考的话题。在当前的初中数学教学中,学生中不缺乏基础扎实、能力超强的人,但具有科学的、完整的数学思维的学生却很少,尤其是具有逆向思维的学生更是凤毛麟角。大多数学生在平时的学习中仍然按照传统的解题思路,降低了解题效率。 Under the background of new curriculum reform, junior high school mathematics teaching has shown many bright spots and made a series of gratifying achievements. During the long-term teaching practice, more and more junior middle school math teachers gradually changed their traditional teaching thinking and mode, started to combine with the new situation and explored diversified teaching methods. Among them, the training of students to reverse thinking has become the topic of concern for many front-line teachers and thinking. In the current middle school mathematics teaching, the students do not lack a solid foundation and super-capable people. However, there are only a few students who have a scientific and complete mathematical thinking. In particular, students with reverse thinking are even rarer. Most students in the usual learning is still in accordance with the traditional problem-solving ideas to reduce the problem-solving efficiency.
