中学生物课,是学习生物体和生物界发生发展规律的一门基础课程。生物课的教学目的之一,是使学生了解生物学知识在农业、医学、工业等方面的应用,并为学生参加工农业生产和进一步学习打下基础。若教师照本宣科,让学生死记硬背,是学不好的。只有让学生结合实际,动脑、动手、动口,生动活泼地学习,才能激发他们的学习热情,培养他们浓厚的学习兴趣,使他们积极主动地去思考、去发现,才能获得真正的知识。实践证明,凡是学生亲自观察过、亲自动手操作过的知识就不易遗忘。只有有了丰富的感性知识,对于原理、概念就容易掌握。
The biology class in middle school is a basic course for studying the law of development in biology and biology. One of the objectives of the biology class is to enable students to understand the application of biological knowledge in agriculture, medicine, industry, etc., and lay a foundation for students to participate in industrial and agricultural production and further study. If teachers follow this book, it is not good for students to memorize. Only by allowing students to combine practicality, brains, hands, gestures, and lively learning, can they stimulate their enthusiasm for learning and cultivate their strong interest in learning so that they can actively think and discover, and they can acquire real knowledge. Practice has proved that any knowledge that students have personally observed and manipulated by hand is not easy to forget. Only with a wealth of emotional knowledge, it is easy to grasp the principles and concepts.
