小学升入初中的学生,刚开始对各学科都有着浓厚的兴趣,可是有的学生上数学课没多久,兴趣就慢慢消失,这几乎成了初一数学教学的一个普遍性的问题。《数学课程标准》中指出:“学生的数学学习内容要有利于学生主动地进行观察、实验、猜测、验证、推理与交流等数学活动。”但通过教学,我发现初一的学生主动观察、实验、猜测、验证、推理与交流的能力相对薄弱,如果加以训练,学生可在一年内逐步形成这样的能力。为使学生形成主动观察、实验、猜测、验证、推理与交流的能力, Primary and junior high school students, initially beginning to have a strong interest in all subjects, but some students math classes soon, the interest gradually disappeared, which became almost the first math teaching a universal problem. The standard of mathematics curriculum states: “The mathematics learning content of students should be conducive to students’ initiative in observing, experimenting, speculating, verifying, reasoning and exchanging math.” But through teaching, I found that the first-day students take the initiative The ability to observe, experiment, guess, verify, reason and communicate is relatively weak, and if trained, students can gradually develop such abilities within a year. In order to enable students to take the initiative to observe, experiment, guess, verify, reasoning and communication skills,
