微实验指的是根据教学需要,由学生课后独立完成的微型实验,目的在于拓展学生的思维,巩固学生的知识基础。实验是学生获取生物知识的重要途径,因为学生可以通过实验深入探究生物世界的奥秘,从而积极参与生物学习活动,不断提高自身的实践能力、合作能力和逻辑分析能力。而有限的课堂时间往往难以为学生创造充足的实践机会,很多生物实验难以顺利开展,对学生更深入地理解生物知识形成了一定程度的阻碍。所以,利用课外时间,结合学 Micro-experiment refers to the mini-experiment independently completed by students after class according to the teaching needs, the purpose is to expand students ’thinking and consolidate the students’ knowledge base. Experimentation is an important way for students to acquire biological knowledge because students can explore the mysteries of the biological world through experiments and actively participate in biological learning activities to continuously improve their practical ability, cooperative ability and logical analysis ability. The limited classroom time is often difficult to create enough practical opportunities for students, many biological experiments is difficult to carry out, to students a more in-depth understanding of biological knowledge formed a certain degree of obstruction. Therefore, the use of extra-curricular time, combined with learning
