Research On Element Compounds Teaching Strategy Of High School

Element compounds are an important part of middle school chemistry teaching content, accounting for 60 percent of the chemistry teaching content of middle schools.The knowledge of element compounds will provide the necessary foundation for modern life,study,production and research. Element compounds in the teaching process,can penetrate STSE education, to lead students to address the concerns of life related to chemical,guides the student to the correct understanding of the relation between science,technology,environment,society,improve the students' scientific literacy,gradually form the thought of sustainable development. In addition, the element of compound knowledge learning is an effective way to cultivate and improve students' chemistry subject ability, can help students better understand the basic concepts and basic chemical theory, so as to lay a foundation for the cultivation of the students' ability to migrate.However, because of the new curriculum standard experiment textbook highlighted elements compound knowledge application in the production and living, has weakened the concept of family, led to the textbook arrangement is not a system, so there are some shortcomings in knowledge of systematic. Plus in the process of teaching,many teachers only pay attention to imparting knowledge, does not pay attention to the guidance of the learning method, before and after the knowledge of cohesion, and do not pay attention to the experimental teaching, the above a variety of reasons led to the students' mastery of the knowledge base learning element compounds is not strong, not comprehensive,knowledge cannot be networked, and much less integrated use of knowledge to solve practical problems. How to find the right teaching strategies to improve the teaching efficiency of the element compounds is the problem for this article.The research methods used in this article are mainly based on the research method of action, and also use the literature method, questionnaire survey method, interview method and so on. This paper selects five targeted teaching strategies, and preliminary research shows that these strategies are effective.The full text is divided into five chapters:The first chapter is introduction. Mainly includes: the problem is proposed, the research present situation, the research content and significance, research ideas and methods.The second chapter is the core concepts and theoretical basis.Including the meaning of teaching strategies and the relationship with related fields, characteristics,classification and related theoretical basis.The third chapter is a high school chemistry element compounds to the investigation of present situation of teaching and learning. Through questionnaire investigation,interview and listening to lectures, understand the elements of compound teaching and learning situation.The fourth chapter is a high school chemistry element compound teaching strategy selection and application. First choose the principle of teaching strategy is introduced,and then select the teaching strategy. Strategy a: class leading case auxiliary preview teaching strategy; Strategy 2: use a variety of ways to stimulate students interest in learning teaching strategy, strategy 3: teaching strategies that relate to students'knowledge;Strategy 4: the experiment inquiry teaching strategy, strategy of five: through the problems lead to cultivate students ability of independent exploring teaching strategies. And according to the teaching strategy in teaching experiment, and finally the result analysis.The fifth chapter is conclusion and reflection.
