运用思维导图构建初中化学知识体系的策略探究

初中化学是化学学习的入门阶段,具有基础性和启蒙性,让学生掌握最基础的化学知识与技能,能够从化学的角度认识物质,提高学生运用化学知识解决实际问题的能力。正是这样的学科特点,初中教学内容比较基础,记忆知识较多,这就需要学生具有发散性思维和科学思维能力。但在课堂教学中教师一般采用媒体和语言讲述传授知识,虽然学生能听懂,但过后对知识的认识却模糊不清,加上本身缺乏衔接性和逻辑性,没有形成网络体系,很难迅速理清知识点之间的逻辑关系,导致无法有效提取所学知识,最终导致无法灵活运用于实际问题。对教师如何引导学生在正确理解所学知识的基础上进行有效记忆和运用提出了更高要求。教师采用思维导图法教学,透过思维导图的分析和构建,启发学生对教学内容的理解,不仅可以帮助学生发挥潜能,更能刺激创造性思维。

junior high school chemistry is the beginning stage of chemistry learning,with basic and enlightening,let students master the most basic chemical knowledge and skills,can understand the material from the perspective of chemistry,improve students'ability to use chemical knowledge to solve practical problems.It is this kind of subject characteristic that junior middle school teaching content is more basic,memory knowledge is more,this needs the student to have divergent thinking and scientific thinking ability.But teachers usually use in the classroom teaching media and language knowledge,while the students can understand,but after the understanding of knowledge is unclear,and lack of cohesion and logic,not form a network system,it is difficult to quickly clarify the logical relationship between the knowledge points,result in unable to extract knowledge effectively,eventually lead to cannot be flexibly applied to practical problems.It puts forward higher requirements for teachers to guide students to remember and use the knowledge effectively on the basis of correct understanding.Teachers use mind map teaching method,through the analysis and construction of mind map,to inspire students'understanding of the teaching content,can not only help students develop their potential,but also stimulate creative thinking.
