学生在学习过程中,比较注重概念和规律的理解,对文本的理解比较到位,但对课本的插图很容易忽视。通过对电磁波的发射和接收插图的解读,希望教师能关注插图、研究插图、解读插图,学生能更容易接受图象所表达的信息。 Students in the learning process, pay more attention to the concept and the understanding of the law, understanding of the text in place, but illustrations of textbooks is easy to ignore. Through the interpretation of the electromagnetic wave emission and reception illustrations, we hope that teachers can focus on illustrations, study illustrations, interpret illustrations, and students can more easily accept the information expressed in the images.
