课堂教学作为整个教学过程的中心环节,具有很强的科学性和联系性,事前必须做充分的准备,否则就不能取得理想的效果。所以无论教师的教龄长或短,教学经验多或少,课前准备是必须的。对于青年的教师来说,课前准备更是教师从事教学不可缺少的基础工作。本文作者对生物教师对课前的准备工作发表了自己的见解。 Classroom teaching, as the central part of the whole teaching process, is highly scientific and relevant. It must be fully prepared in advance, otherwise it will not achieve the desired result. Therefore, regardless of the teacher’s teaching age or short, more or less teaching experience, pre-class preparation is necessary. For young teachers, pre-class preparation is more essential for teaching teachers to do the basic work. The author gives his own opinion on the preparation of the biology teacher for the class.
