《普通高中生物课程标准》指出,学生是学习的主人,而教师只是一个组织者、引导者和鼓励者,因此在教学过程中,教师要为学生创设各种情境,激发学生的思维,促进其自主学习,并且提供充分的活动机会,引导他们在自主探究和合作交流的过程中,真正理解和掌握基本的生物知识和技能、生物思想和方法,获得生物活动经验,从而提高他们学习生物的兴趣和效率。 According to the “Standard of Biology Curriculum for Common Senior High Schools”, students are the masters of learning and the teacher is only an organizer, guider and encourager. Therefore, during the teaching process, teachers should create various situations for students to stimulate their thinking and promote their Self-study, and provide full opportunities for activities to guide them in truly understanding and mastering basic biological knowledge and skills, biological thoughts and methods, and gaining experience in biological activities so as to enhance their interest in learning biology And efficiency.
