新课程要求教师:“要关注每一位学生的发展。”科学课教学中教师应正确把握好学生自主学习与教师指导的关系,针对探究的不同阶段适时给予学生恰当的指导,成功扮演探究活动的组织者和引领者角色,不断推动学生开展有效科学探究。新课程要求让学生动手实验、观察。学生制订探究活动的方案是科学课教学的重要环节之一,关系到探究是否能如期有效完成。但学生由于受自身知识和能力所限,科学概念基础比较薄弱,考虑问题和制订方案时缺乏周密性和科学性,所以在设计实验方案时需要教师必要的方法性指导。当然教师的指导并不能直接告诉学生应该怎么去做,而是让学生在充分思考的基础上提出自己的 The new curriculum requires teachers: “To pay attention to the development of every student. ” Teachers in science teaching should correctly grasp the relationship between student self-learning and instructor guidance, appropriate guidance for students at different stages of inquiry, the successful play Explore the role of organizer and leader of the activity, and constantly promote students to carry out effective scientific inquiry. The new curriculum requires students to experiment and observe. One of the most important aspects of teaching science is to develop a program of inquiry activities for students, which is related to whether the inquiry can be effectively completed on schedule. However, due to their limited knowledge and ability, students have a weak foundation of scientific concepts. Due to their lack of thoroughness and scientificalness in considering problems and formulating programs, students need the necessary methodological guidance in designing experimental programs. Of course, the guidance of teachers and students can not directly tell how to do it, but let students on the basis of full consideration put forward their own
