一、充分利用和开发现有的教学资源,创设优良的教学情境,激发学生的认知热情1.积极创造条件开展实验探究教学,让学生在实践中获得更深的情感体验,激发学生的认知情趣。学生对化学兴趣大多起源于对化学实验的好奇。化学实验将化学现象直观地展现在学生面前,当学生面对颜色、形态、气味,光热等多种变化交织在一起的化学现象时,多种感觉器官同时受到刺激,很容易促进他们的思维进入积极的兴奋状态。尤其是在初中阶段学生形象思维占主导地位,学生的注意力很容易被一些明显有趣的事物所吸引。
First, make full use of and develop existing teaching resources, create excellent teaching situations and stimulate students ’cognitive enthusiasm 1. Actively create conditions to carry out experimental inquiry teaching so that students can obtain deeper emotional experience in practice and stimulate students’ cognition Fun. Most of the students’ interest in chemistry stems from the curiosity of chemistry experiments. Chemistry Experiments Visualize chemical phenomena in front of students. When students face chemical phenomena in which colors, morphologies, scents, photothermal and other changes are intertwined, a variety of sensory organs are simultaneously stimulated to easily promote their thinking Into a positive state of excitement. Especially in the junior high school image of students dominated thinking, the student’s attention can easily be attracted by some obvious interesting things.
