Design And Implementation Of Problem-solving Teaching Mode For Chemistry In Junior Middle School

From theoretical study of psychology to combining with subject teaching practices,problem resolution has developed for a long time with relatively mature theoretical results and valuable practical experience.Grade three in middle school is the enlightenment stage of chemistry.Aiming at chemistry for grade three students in middle school,the author designed problem resolution teaching designs in line with the learning characteristics of middle school students in grade three,analyzed and reflected on teaching application,summarized problem resolution teaching modes adapting to classroom teaching to make it easy for students to learn high school chemistry.The paper has five parts.By putting forward chemistry problem resolution teaching research,analyzing basic theories of problem resolution and investigating the situation of problem resolution,the author constructed chemistry problem resolution teaching design modes,designed chemistry problem resolution teaching designs of different course types and implemented them,conducted a comprehensive analysis about the implementation results of different cases and drew a conclusion.The author put forward research object,briefly described research objectives,significance,research status and research methods in the first part.The second part is about the basic theories of middle school chemistry problem resolution.The author mainly analyzed basic concepts,described the characteristics and psychoanalysis of middle school chemistry problem resolution,summarized the types of middle school chemistry problem resolution and put forward the educational value of chemistry problem resolution teaching design based on former outstanding achievements.The third part is about the teaching status of middle school chemistry problem resolution.The author conducted a questionnaire survey about the understanding of all middle school chemistry teachers in the survey area toward problem resolution and the application of problem resolution and analyzed the survey results.The fourth part is about the construction of chemistry problem resolution teaching models and the design and analysis of specific cases.The author put forward the general patterns of middle school chemistry problem resolution teaching design,analyzed the requirements of middle school chemistry problem resolution teaching models towards textbooks,teachers and students.Then the author carried out four types of problem resolution teaching designs including basic theoretical knowledge,experiment,calculation and experiment exploration,summarized the notes when designing.The author did a test in a experimental class,conducted teaching reflection and research analysis after the test,and then proposed recommendations of middle school chemistry problem resolution teaching design.The fifth part is the research summary and outlook.Of course,teaching design is careful and rigorous theoretically,but there are many unexpected situations in the actual teaching process.So teachers need to analyze specific issues or utilize them to make classroom teaching more real and interesting.
