Research On The Teaching Of Chemistry For Senior One Based On PBL Tutorial Case

At present,many primary and secondary schools in various provinces and cities across the country are using tutorials,but as far as the status quo of tutorials is concerned,most of the tutorials are practice questions such as filling in blanks,multiple choice questions,etc.Then,students can easily find answers in textbooks without thinking.This study improves this traditional study case,through the "PBL-based study case(question-based study case)" applied to the teaching of compulsory element and compound knowledge of senior high school chemistry,so as to explore whether "PBL-based study guide" can improve chemistry teaching Effectiveness,whether it has a positive impact on students.In the specific research process,this article uses the experimental method to implement the teaching process in the experimental class and the control class,the experimental class uses the "PBL-based study plan" teaching,and the control class adopts the traditional "five-year simulation,three-year college entrance examination" teaching plan.Finally,through a series of empirical studies such as pre-test,survey questionnaires,interviews,post-test,and observation and analysis of learning situation to analyze the positive impact of the "PBL-based tutorial case" in the teaching process.The thesis consists of four chapters:The first chapter is "Introduction",it mainly explains the background of the topic,the significance and value of this research,the current status of research at home and abroad,and the content and methods of research.The second chapter is "Related Concepts and Theoretical Basis",introduced the concept of PBL,the concept of study case,and the concept of PBL-based study case,and take constructivist learning,recent development zone theory,meaningful learning as the theoretical support of this thesis.The third chapter is "Chemistry Classroom Construction Based on the PBL Study Guide",it mainly introduces the general links of the application of tutorials before,during,and after class and the early analysis of the chemistry classroom based on the PBL tutorial.The fourth chapter is "Research on the Teaching Practice of Elements and Compounds Based on the PBL Guidance Case".The research results are formed mainly through post-studyinvestigation and interview analysis of the research,observation and analysis of the learning situation of the research object and analysis of student achievements during the course of teaching.Finally,the research conclusions and deficiencies of this paper are formed.The conclusions show that after using PBL-based tutorials for teaching,students' learning attitude,learning habits,and teaching effects have been improved.
