A Comparative Study On After-Class Exercises In Chemistry Textbooks In Chinese And Mongolian High Schools

Chemistry is a central subject and serves as a link between the past and the next in the scientific system.In high school,it is closely related to the college entrance examination.Chemistry textbooks are one of the important materials for learning chemistry,and exercises in chemistry textbooks are also an important part of learning,consolidating and applying chemical knowledge.Students can practice the textbook exercises after class according to the teacher’s explanation.In this paper,literature study,comparative study,data analysis and other methods are used to compare the common high school chemistry textbooks "Chemistry Required Volume 1","Chemistry Required Volume 2"(hereinafter referred to as the teaching materials for People’s Education Press)and the Mongolian high school chemistry textbooks “ΧИМИ IX”,“ΧИМИX”,“ΧИМИ XI”.(hereinafter referred to as Mongolian textbooks)after school exercises part of the number,type,difficulty comparison and analysis.Through the analysis of exercises in Mongolian teaching materials,learning from the advantages of Mongolian teaching materials to improve the advantages of the integration,for China’s people’s education version of the teaching material to provide available suggestions,put forward reasonable suggestions to the front line teachers,so that the front line teachers broaden their horizons,break the traditional way of teaching.Based on the comparative analysis of the number,type and difficulty of after-class exercises in chemistry textbooks of the two countries,the characteristics and differences of after-class exercises in chemistry textbooks of the two countries are summarized,and reasonable suggestions are put forward for the compilation of after-class exercises in chemistry textbooks of our country.In this way,front-line chemistry teachers can make better use of after-class exercises for teaching,at the same time to improve students can better use of knowledge to analyze and solve problems.Through comparative analysis,it is found that the two countries have their own characteristics of teaching material exercises.In terms of the number of exercises,there are757 exercises in the chemistry textbooks of Mongolia,such as “ΧИМИ IX”,“ΧИМИX”,“ΧИМИ XI”,there are 292 exercises in the chemistry textbooks of senior high schools published by the Peoples Education Press(peoples Education Press).The difficulty of the chemistry textbooks of senior high schools in Mongolia is slightly higher than that of the chemistry textbooks published by the Peoples Education Press(peoples Education Press),however,the difficulty of the background level and the reasoning level is slightly lower than that of the chemistry textbook published by the Peoples Education Press.According to the research results,the following suggestions are provided:1.Reasonably supplement the number of exercises at the same time increase the number of targeted exercises.2.Will exercise the life,increase from the production life,the scientific exercise.3.Increase the proportion of open-ended questions and practical questions.
