初中科学是一门囊括理化生等基础自然学科在内的综合性学科,里面包含了内容丰富的自然科学知识及抽象的概念和规律现象,所以,教学过程中许多学生会感到难以理解,甚至枯燥乏味。这就需要一线教师认真分析学生的实际认知规律并发挥教学内容的优势来激活学生认知兴趣,然后设置有计划、有步骤、有针对性的教学方案和流程来引导学生进行自主探究,通过设置关键问题来完善师生互动,让学生在探索实践中,完成知识内化和迁移,最终提高课堂效率。结合多年教学实践经验,对怎样完善课堂流程,提高课堂效率进行探索与研究。
Junior high school science is a comprehensive discipline that includes the basic natural sciences such as physics, chemistry and chemistry. It contains rich content of natural science and abstract concepts and laws. Therefore, many students in the teaching process find it hard to understand or even dull . This requires front-line teachers to carefully analyze the students ’actual cognitive rules and give full play to the advantages of teaching content to activate students’ cognitive interests. Then they set up planned, step-by-step and targeted teaching programs and procedures to guide students to conduct autonomous exploration through Set key issues to improve the interaction between teachers and students, so that students in the exploration practice, the completion of knowledge internalization and migration, and ultimately improve classroom efficiency. Combined with years of teaching experience, how to improve the classroom process, improve classroom efficiency to explore and research.
