案例背景数学是一门抽象的科学,对于初中生来说,这种抽象会影响学生的学习情绪,使他们经常处于一种被动的学习情境中。被动地接受知识,久而久之就会失去对数学学习的兴趣,但兴趣是最好的老师,有了兴趣,学生在学习的过程中就会自觉地克服困难,排除干扰,积极主动学习,失去兴趣,就失去了推动学生学习最有利动力。因此,在课堂教学过程中,如何使学生对所要学习的内容产生兴趣,显然比如何枯燥地讲 Case background Mathematics is an abstract science, for junior high school students, this abstraction will affect the students’ learning sentiment, so that they are often in a passive learning situation. Passively accept the knowledge over time will lose interest in mathematics learning, but interest is the best teacher, with interest in the process of learning students will consciously overcome difficulties, eliminate interference, active learning, loss of interest, It lost the most favorable motivation to promote student learning.
