Research On Teaching Design Of Elemental Compounds Based On Problem Chain

Classroom is an important platform for presenting knowledge.Classroom teaching should highlight its basic,contemporary and humanistic characteristics.Teachers should pay attention to arousing students' thinking and solving doubts in problem situations,and cultivate students' inquiry ability by constructing diversified learning methods.Therefore,in classroom teaching,teachers should control the dialectical relationship between questioning and inquiry,through the introduction of question chain,build a systematic inquiry framework around key knowledge,promote the change of learning style,and cultivate students' self-learning ability.Based on this,this paper focuses on the design of high school chemistry classroom problem chain,using literature research,case analysis and interviews and other research methods to explore teaching practice.The paper consists of five parts.The first part elaborates the background,significance,problems and main methods of the research,and summarizes the latest achievements and trends of the research on the problem chain at home and abroad by sorting out the relevant literature.The second part puts forward the theoretical basis of the application of the problem chain in high school chemistry classroom teaching,and explores the process and design ideas of the case development of the problem chain teaching.The third part is based on the theoretical level,analyzing the design of the high school chemistry teaching case with the problem chain as the core;the fourth part is based on the practical level,through the design and organization of the teaching case,analyzing the practical application of the problem chain in the high school chemistry classroom teaching;the fifth part elaborates the main research conclusions of this paper.Through the research,it is found that guiding students to study and explore independently in high school chemistry class by question chain can help improve students' ability to discover,raise and solve problems,enhance students' thinking level,stimulate their interest in learning,enhance their awareness of inquiry and innovation,and is of great significance for optimizing teaching process,expanding teaching theory and enriching teaching practice of question chain.
