Comparative Study On Experiments In Chemistry Textbooks Of Mainland And Hong Kong High Schools

Chemical experiment is the main way to learn chemistry,is also the main tool to master chemical knowledge,understand the material world,is one of the core contents of high school chemistry curriculum,and the process of experimental inquiry is also an important process from the rise of perceptual knowledge to rational knowledge.In this paper,Comparative Law,literature research method,action research method,empirical research method and content analysis method,through the comparison of the People's Education press published in the General high school curriculum standard experimental textbook Chemistry Experiment and Hong Kong mainstream textbook "New 21st century Chemistry" in the experimental choreography concept and some typical experimental design scheme,The characteristics of the present experiments are studied.Under the background of the new curriculum standard,this paper draws lessons from the relatively excellent experimental design concept and more reasonable arrangement in Hong Kong's new 21st century chemistry,and puts forward more reasonable suggestions and improvement measures for better writing the chemistry experiment in the Humanistic edition,stimulating students ' interest in learning chemistry,and improving the core accomplishment of students' subjects.This article is divided into six parts:Part I:Introduction.Firstly,we understand the background of the comparative study of chemistry textbooks and chemistry textbooks in Chinese high school,and secondly,from the historical status quo of textbook research,the comparison of different versions of high school chemistry textbooks in China,the comparison of chemistry textbooks in high schools in mainland China,the comparison of the experimental parts of high school chemistry textbooks,and the further understanding of the purpose and significance Determine the research object and research method.Finally,through the literature review,the reasonable construction of the basic structure of this paper to guide the smooth expansion and writing of the paper.The second part:The overall comparison of experimental writing.This paper makes a comprehensive comparative study of the teaching materials and the chemistry of the 21st century in Hong Kong from the aspects of the whole textbook,the type,quantity and distribution of the experiment,and the curriculum objectives.The third part:the comparative empirical study of typical experiments.The main features of the two edition of the chemical textbook were obtained by empirical study and comparative analysis in three groups of typical experiments,such as distillation,standard solution preparation of a certain amount of material,and neutralization titration of strong acid and strong alkali in the Chinese version of the chemistry textbook.Part IV:Practice and exploration of typical experiments in teaching.On the basis of comparative analysis,the distillation experiment is selected to practice and explore in teaching.The distillation experiment in two versions of teaching materials was brought to the real teaching classroom,and according to the teaching teachers,experimental students and teachers,the paper collected and collated the feedback information from many angles,and finally,the objective analysis and evaluation concluded that there were significant differences between the design concept and the design of the experimental scheme and the human version of the teaching materials in Hong Kong.Part V:Experimental Reference and transformation.On the basis of the comparative study of the two edition teaching materials,using the idea of summarizing the experimental device diagram,introducing the molecular polarity experiment,improving the original battery experiment and drawing lessons from the mobile experiment of colored ions,we can draw lessons from some of the better experimental design ideas and experimental devices in the new 21st century chemistry of Hong Kong,make bold improvements,and put more scientific and The experiment which is more favorable to the development of students' core accomplishment is introduced into the teaching materials in order to improve the efficiency of chemistry teaching.Part VI:Research conclusions and prospects.Through the overall comparison of experiments,the typical experiment contrasts with empirical research,the practice and inquiry of typical experiments in teaching,and the reference and transformation of experiments,and draws the idea that the chemistry teaching materials in Hong Kong pay more attention to the diversification of experimental design and pay more attention to helping students to prepare for their future life than the human teaching version of Chemistry teaching materials.Pay more attention to the color collocation of experimental content typesetting,pay more attention to the summary of similar experimental device diagrams,and pay more attention to the cultivation of students' experimental inquiry ability.Finally,it is hoped that the experimental design of humanistic chemistry textbook will pay attention to life,the promotion of humanities accomplishment,the cultivation of inquiry ability and the matching of experimental picture color.It is hoped that chemical experiment teaching can be further optimized to improve the quality of chemical teaching materials in China.
