很多中学生在学习过程中都会遇到偏科的问题,往往这部分学生数学成绩都不太理想。在他们看来,数学是很难学的,不仅枯燥无味,而且抽象难懂。事实上,数学是一种认识科学的工具,在科学研究中有着举足轻重的地位,早在1687年艾莎克·牛顿的著作《自然哲学的数学原理》发表的时候,数学就与科学紧密相连。造成学生对数学的偏见得原因有两个,一是学生的学习方法不正确,二是是教师的教学方法出了问题。学生学习方法不正确,导致学习效率低,学生越学越没信心。教师教学方法不合适,学生就越学越困难,事倍功半。在教学中,教师需要良好的教学方法。,本文通过讨论分类讨论在教学中的应用,来发现问题,指导教学工作。
Many middle school students in the learning process will encounter the problem of partial subjects, often this part of the students math results are not ideal. In their opinion, mathematics is hard to learn, not only boring but also abstractly difficult to understand. In fact, mathematics is a tool for understanding science and plays a decisive role in scientific research. As early as 1687, when Ishak Newton’s The Mathematical Principles of Natural Philosophy was published, mathematics was closely linked with science. There are two reasons why students prejudice mathematics. One is that students ’learning methods are not correct, and the other is that teachers’ teaching methods have a problem. Students ’learning methods are not correct, resulting in low learning efficiency and lack of confidence in students’ learning. Teachers inappropriate teaching methods, students learn more difficult, less effective. In teaching, teachers need good teaching methods. This article discusses the application of the classification discussion in teaching to find out the problems and guide the teaching work.
