在几年职业高中的化学教学实践中,我们结合职中的特点,紧密联系生产、生活实际进行化学教学,大大提高了学生学习化学课的积极性,收到了良好的效果。我们的作法是: 一、用生活中的事例激发学生对化学的兴趣入学后的第一节课我们没有进行新课,一上课就向学生提了生活与化学有关的问题。如:为什么焰火五颜六色?为什么变色镜一见阳光就会变色?为什么电视机一通电,荧光屏就会显示图象?为什么近些年全
In the practice of chemistry teaching in vocational high schools over the past few years, we combined the characteristics of the post and closely linked production and life to chemistry teaching, which greatly improved the enthusiasm of students in learning chemistry courses and received good results. Our approach is: First, to stimulate students’ interest in chemistry with examples of life In the first lesson after entering school, we did not conduct a new class. When a class started, students were asked questions related to life and chemistry. Such as: Why is the fireworks colorful? Why does the photochromic lens change color when it sees the sun? Why does the TV set display an image when it is powered on? Why is it so recent?
