在高中二期课改中,生命科学教材的很大一个变革是实验,不但实验的量大大增加,而且很多实验由原来的验证性实验转变成了现在的探究性实验。探究性实验就是教师指导学生自己去设计,去操作,形成一种自由地表达和选择创意的氛围,能培养学生开拓创新的精神,这就对学生提出了更高的能力要求。生命科学本身就是一门实验学科,是通过实验让学生认识生命现象,理解生命科学的概念和规律,因此实验 In the second grade of high school curriculum reform, a great change in the life sciences textbooks was experimentation. Not only did the amount of experiments increase greatly, but many experiments changed from the original verification experiment to the current inquiry experiment. The exploratory experiment is that the teacher instructs the students to design, operate, and form an atmosphere of free expression and choice of creativity. This can cultivate students’ spirit of pioneering and innovating, which puts forward higher requirements for students. Life science itself is an experimental discipline. It is through experiments that students understand the phenomena of life and understand the concepts and laws of life sciences.
