一、问题的提出 目前的生物学教学,由于诸多原因,往往忽视学生动手能力、观察能力和思维能力的培养,不科学的学习方法常常会影响教学效果。当前教育由应试教育向素质教育转轨过程中,生物学教学更应注重培养学生观察、分析问题的能力,能独立思考,有创造性思维的本领,同时并通过教学,教会学生将学到的知识应用到实际中去,能理论联系实际,能适应社会发展的需要。为此,我们课题组根据初中学生对知识的获取是从感性认识到理性认识认知规律,将初级 First, the problem proposed The current biology teaching, due to many reasons, often overlook students’ hands-on ability, observation ability and thinking ability training, unscientific learning methods often affect the effectiveness of teaching. At present, education shifts from exam-oriented education to quality education. Biology teaching should focus on cultivating students’ ability to observe and analyze problems, and be able to think independently and have creative thinking skills. At the same time, through teaching, students are taught to apply the knowledge they have learned. When we go into practice, we can connect theory with reality and adapt to the needs of social development. To this end, our task force has learned from the perceptual knowledge to the rational cognitive cognition, based on the junior students’ knowledge acquisition.
