The Teaching Design And Research Of “Issue-driven Guidance Case” About Chemistry In Senior High School

With the advancement of curriculum reform,there have been many teaching models in our country,where the case study guide and problem-driven education is one of the representatives.And we proposed a "problem-driven Guidance case" teaching model,fusing the advantages of the two teaching modes in this paper.The proposal of this model is based on constructivist learning theory,according to students' existing knowledge and experience,taking questions as a starting point and the problem as the main support.Furthermore,it can cultivate the enthusiasm of students' self-learning and the ability of problem-solving independently through the guidance of teachers,making students establish confidence in learning and develop healthily.The first part of this paper is an introduction,analyzing the background of "issue-driven guidance case",the status quo and the research method.Simultaneously,the first part also reviews the problems in issue-driven teaching and the guidance case teaching.The second part analyzes the related concepts and research status of the "problem-driven guidance case".First,we define the concept of "problem-driven guidance case".Then we analyze the present situation of the research about "problem-driven guidance case" in China.The third part is the theoretical foundation,elaborated the guiding significance of constructivism theory,zone of proximal development theory,discovery learning theory and problem-driven teaching thought to the research.The fourth part is questionnaires and teacher interviews,investigating the usage of chemical guidance case and the ability of the students' self-learning,to give an insight into guidance case and issue-driven teaching models' application in teaching through interviews with teachers.The fifth part makes the design and implementation about "problem-driven guidance case",expounding the strategy of "problem-driven guidance case" on design,the teaching process,how to employ problem-driven in the process of teaching and the analysis of the effect of the implementation as well.The sixth part is the result of research and discussion,which the results show that after using the case study guide,students' self-learning ability is generally improving.
