初中数学是基础性的学科内容,其教学的主要目的在于引导学生掌握一定的数学学习方法和学习思路,培养学生较强的逻辑推理能力。过去传统的题海战术过于理论性、枯燥,学生不能够根本性地掌握知识和学习思维方法。对此,教师需要找到一种激发学生乐趣,让学生感受数学本质乐趣的方法。变式教学作为一种解题思路,教学方法主要是以拓展形式出现的,它是对原本内容范畴的拓宽,以变来展示数学知识的不变、灵活等,不仅能够激发学生学习的兴趣,而且还能够系统性地提升学生数学的综合技能。基于此,本文从一题多解、一题多变、一法多用三个方面探讨变式教学在初中数学课堂教学中的有效应用。
Junior high school mathematics is a basic subject content, the main purpose of teaching is to guide students to master a certain number of mathematical learning methods and learning ideas, develop students strong logical reasoning ability. The traditional problem-solving tactics in the past were too theoretical and boring. Students could not fundamentally acquire knowledge and learning thinking methods. In this regard, teachers need to find a way to stimulate student fun, let students feel the essence of mathematical fun. Variant teaching as a problem-solving ideas, teaching methods mainly in the form of expanded, it is to broaden the scope of the original content, in order to demonstrate the same mathematical knowledge, flexibility, etc., not only to stimulate student interest in learning, But also systematically enhance the overall skills of student math. Based on this, this article discusses the effective application of variant teaching in junior high school mathematics classroom teaching from three aspects: one problem multiple solution, one question changeable, one method multiple use.
