最近,我很荣幸地参加了重庆市生物实验录像课比赛,面对这一次难得的锻炼机会,经过反复推敲,我最终选做的课题是探究实验《光对鼠妇生活的影响》。此实验是人教版初中生物学教材七年级上册《环境对生物的影响》一节中的实验部分。我选择这堂课的理由如下:一、理解此课在初中生物学教学中的特殊地位《光对鼠妇生活的影响》这个实验是初中生第一次接触探究实验,对认识和掌握探究实验的基本步骤方法有着重要意义。实验不仅在于让学生认识到光对鼠妇生活是否造成影响,更重要的是让
Recently, I was honored to participate in the Chongqing Experimental Biology Video Contest. In the face of this rare opportunity for exercise, after repeated scrutiny, my final project was to explore the impact of the experiment on the life of the woman. This experiment is the experimental part of the seventh edition of the PEP textbook for junior high school of the People’s Education PEP “Environmental Impact on Biology”. I chose this lesson for the following reasons: First, to understand this lesson in the special status of junior high school biology teaching “light on the impact of life of the mouse woman,” This experiment is the first time junior high school students to explore research, understanding and master of inquiry The basic steps of the experiment are of great significance. The experiment is not only to make students realize whether light has an impact on the life of a rat woman, but more importantly,
