2015～2020 Shanxi Province Senior High School Entrance Examination Questions Research And Teaching Suggestions

The senior high school entrance examination is a final exam in the nine-year compulsory education stage.Chemistry is one of the subjects of the academic proficiency test.The experimental content is the focus of the annual Shaanxi senior high school entrance examination.However,there are relatively few researches on the chemistry experiment questions in the Shaanxi Senior High School Entrance Examination.Therefore,we choose to study the chemistry experiment questions in the past 6 years in the Shaanxi Province Senior High School Entrance Examination,analyze their proposition characteristics,and count the key points of the chemistry experiment questions in the Shaanxi Middle School Entrance Examination,combined with the chemistry of junior middle school students.Review the status quo,put forward corresponding teaching strategies for students’ problems and design chemistry experiment review teaching cases,and then apply this to actual teaching,and finally put forward corresponding teaching suggestions,hoping to provide useful practice for middle school chemistry teaching and students’ efficient preparation for exams reference.The main research contents are as follows:First,clarify the research background of the thesis through analysis and collation of relevant literature.By summarizing the status quo of research on chemistry test questions in the domestic senior high school entrance examination,it is found that there are large differences in the preparation of middle school examination questions in different regions in China,and there is less research on chemistry test questions in the Shaanxi senior high school entrance examination.Therefore,the experimental questions with higher scores in the chemistry questions of the Shaanxi Senior High School Entrance Examination in the past 6 years are selected for systematic research,and the basic ideas of the thesis are constructed to clarify the purpose and significance of the research.Then,in order to standardize the research content of the thesis,the related research content of the thesis is defined,and the chemistry experiment questions of the high school entrance examination and the middle school entrance examination and the teaching strategy of chemistry review are clarified.On this basis,taking the chemistry test questions in the Shaanxi Senior High School Entrance Examination in the past 6 years as the research object,it conducts research and analysis on the middle school examination questions from the basic overview of Shaanxi Senior High School Entrance Examination,the distribution of question type scores,and the content dimensions of the experimental test questions.The study concluded that the reform of Shaanxi’s junior high school level examination in 2020 has increased the total score of the chemistry subject;in the past six years,the proportion of chemistry experiment questions in the Shaanxi high school entrance examination has been relatively large,indicating that the content of chemistry experiments occupies an important position in the Shaanxi high school entrance examination chemistry examination questions;The content of the experimental questions in the Shaanxi Senior High School Entrance Examination is basically in line with the requirements of the curriculum standards,and the chemistry question setting reflects the characteristics of basic,comprehensive,and daily life.Finally,in order to solve the problems of students’ chemistry review,such as easy to forget knowledge,low learning efficiency,and inability to systematize,structure,and network the learned knowledge;use text analysis and mind mapping methods,and use constructivist theories,Supported by cognitive transfer theory and education evaluation theory,the high-frequency examination chapters are used as the basis for the selection of the thesis teaching cases,including three review cases "Entering the chemical world","The air around us","O2 and CO2 laboratory"Preparation".In order to examine the effect of the teaching case in actual teaching,two parallel classes of a middle school in Jingbian County,Yulin City are selected for research,and test questions related to the teaching case are selected as post-test questions,and the students in the two parallel classes are quantitatively analyzed and compared.For the results,the average scores of the two post-test questions are 41.38 and 38.43,respectively,and there is a difference in the mean;the T test shows that the post-test scores of the two classes are significantly different.It shows that applying the enlightenment gained from the analysis of test papers to the third grade chemistry experiment review class can help students deepen the consolidation of chemistry knowledge,form a systematic knowledge network,and improve students ’ problem-solving ability.At the same time,through teacher-student interviews,it is found that the combination of mind map review can improve students’ enthusiasm and learning ability.Therefore,this research has certain practical reference value for junior middle school chemistry teaching.
