笔者从生物实验教学的实际需要出发,利用普及的数码相机拍摄、整理出大量的实验教学素材,在生物实验教学素材库的构建方面,进行了探索和尝试。一、进行案例记录和研究素材的记录过程是一个信息收集的过程,同时也是研究的过程。每一个实验记录的素材就是一个案例。拍摄的素材除了能展现教材实验基本过程和内容,还应该尽量有所拓展。如七年级上册中“种子萌发的环境条件”实验,发现不同学生对教材描述的“洒一点水,使纸变得潮湿,不能使纸浸泡在水中”和“倒
Based on the actual needs of biological experiment teaching, the author uses a popular digital camera to shoot and sort out a large amount of experimental teaching material, and explores and attempts to build a biological experimental teaching material library. First, the case record and research material recording process is a process of information collection, but also the research process. The material for each experiment record is a case. In addition to shooting the material to demonstrate the basic process of teaching materials and content, but also should try to be expanded. Such as the seventh grade on the ”seed germination environmental conditions “ experiment and found that different students on the textbook description ”sprinkle a little water, so that the paper becomes damp, can not make the paper soaked in water “ and ”down
