在政治课教学过程中,我们会遇到各种各样的疑难问题,特别是高二哲学常识课本中的重点、难点知识。而以往的传统教学过程中,教师往往采用罗列各个已知的真实判断作为论据的方式,直接肯定该命题是正确的。但是,虽经老师反复阐述,学生仍似懂非懂,模棱两可,影响了课堂教学的实际效果。如何改变教法,使学生从抽象的理解变为理性的升华,我运用数学的“反证法”进行尝试,大大提高了教学效果。“反证法”是从结论的反面入手,即先假设命题的结论不成 During the teaching of political classes, we will encounter various difficult problems, especially the key and difficult knowledge in the textbooks of the Philosophy of Senior High School. In the traditional teaching process of the past, teachers often used the method of listing all known true judgments as arguments to directly confirm that the proposition was correct. However, despite repeated explanations by the teacher, students still seem to be ignorant and ambiguous, affecting the actual effect of classroom teaching. How to change the teaching method, so that students from the abstract understanding into a rational sublimation, I use mathematical “anti-evidence” to try, greatly improving the teaching effect. The “anti-evidence method” starts from the opposite of the conclusion, that is, it presupposes that the conclusion of the proposition is not
