“基因控制蛋白质的合成”这一教学内容,一直是教学中的难点,学生学习这部分知识时都感到抽象、困难,因此我制作了一框活动投影片,实践证明效果很好.现将制作和使用方法介绍如下.一、材料用具明胶片、透明彩色墨水、硬纸板、塑料铆钉(可自制,即将塑料丝的两端烫成钉帽)、绘制用具等.二、制作这框投影片由A、B、C、D四张单片复合而成.其中A片为定片,B、C、D为动片.B片的画面内容为一条信使RNA(图中b),C片的画面
The teaching content of “Gene Control Protein Synthesis” has always been a difficulty in teaching. When students learn this part of the knowledge, they feel abstract and difficult. Therefore, I made a frame of activity slides. The practice proved to be very effective. And use methods are described as follows. First, materials, materials, film, transparent color ink, cardboard, plastic rivets (can be self-made, that is, the two ends of the plastic wire into a screw cap), drawing equipment, etc. Second, the production of this box slide by A, B, C, and D are composed of four single pieces. Among them, A piece is a fixed piece, B, C, and D are dynamic pieces. The picture of B piece is a messenger RNA (b in the figure), and the picture of C piece is
