The Design And Practice Of Problem Chain In High School Chemistry Teaching

"The high school chemistry curriculum standard" pointed out: "pay attention to the traditional teaching process into question,found the problem and problem-solving process,pay attention to the development of students’ thinking ability and the cultivation of interest in learning." The important task of talent cultivation today is to cultivate a group of creative and thinking talents,which requires the school education to arouse students’ thinking and cultivate students’ thinking ability.Obviously,good questions can promote the development of thinking and play the role of throwing bricks.However,in the line of teaching,the teacher put forward the problem of the quality is not high,the problem between the lack of systemic problems in the design of a difficult or very shallow,so have a negative effect on the development of students’ thinking.Therefore,this research focuses on the design of the problem chain in high school chemistry teaching,aiming at enlightening the students’ thinking and improving the teaching efficiency.According to the literature review,some experts and teachers have studied the basic theory of problem chain design,including principles,types and functions,but the practical level is relatively lacking.Based on a large number of literatures and summarizing others’ research,this study conducted the following research.First,the problem chain is redefined,and the general principles,types and strategies of teaching chain design are summarized,and the problem chain teaching model is designed.Secondly,it focuses on the case development of the problem chain of the high school chemistry compulsory 1,and the teaching practice is carried out in a class in a high school in shenyang city.Thirdly,it collects data through observation,questionnaire survey and interview method,and detects and analyzes the teaching effect and feasibility of chain teaching.It is found that the application of problem chain teaching in chemistry classroom teaching can improve the teaching efficiency,create a relaxed and lively learning atmosphere,and help teachers to achieve the teaching goal and break through the heavy and difficult points.Problem at the same time,a series of interlocking chain can cultivate students’ problem awareness,arouse students’ thirst for knowledge,and can also improve students mastery of knowledge,and can promote the development of students’ thinking leap.
