Comparative Experiments Of Chemistry Textbooks In Middle Schools Between China And Singapore

Chemical experiment and chemical science are closely linked.Chemical experiment is not only an important part of chemical science,but also makes an important contribution to the formation and development of chemical science.This thesis selects some experiments in the middle school chemistry textbook Discover Chemistry Normal(A)5N published by Singapore Marshall Cvendish Education Press and the High School Chemistry textbook published by the People's Education Press of China as the research object,and the overall compilation and typical experiment of the teaching material experiment.A comparative analysis was made in order to provide a certain reference for the teaching of first-line teachers in China.This paper consists of six parts.The main contents are as follows:Part ?:Introduction.Mainly wrote the reasons for the problems raised,literature review and the framework of the paper.There are three main reasons for the problems:the need for the development of domestic teaching materials,the promotion of international curriculum reform,and the reasons for choosing Singapore textbooks.The literature review is mainly summarized from the following three aspects:Singapore's education system research,comparative study of domestic chemistry textbooks,and comparative research of Sino-Singapore chemistry textbooks.Through reading the review literature,provide ideas,determine the framework of the paper.Part ?:Research Purposes,Significance,Contents,and Methods.With the contrast of the Sino-Singapore chemistry textbooks,find out the difference between the Chinese and the new experiment,absorb some of the essence of the Singapore textbook compilation,learn from the experimental design ideas,guide and help the teaching of high school chemistry teachers in China,improve teaching efficiency,and thus better achieve teaching Objectives;The research content is a corresponding experiment in Singapore Junior Chemistry textbook Discover ChemistryNormal(A)5N and the Chinese People's Education textbook.The methods used in this study are:literature research methods,text research methods,comparative research methods,and empirical research methods.Part ?:The overall comparison of experimental compilation of chemistry textbooks for middle school and middle school.Using statistics and comparative research methods,we made a holistic analysis of Singapore textbooks and PEP textbooks.We compared the type,quantity,and distribution of experiments,and then compared the teaching goals,teaching experiment types,and the effects of the teaching in the universities.analysis.The types of experiments in Singapore mainly include inquiry experiments,miniature experiments,laboratory experiments,and industrial experiments.The proportion of inquiry experiments is relatively large.The experimental types of teaching materials of the People's Education Press of China mainly include experiments,thinking and communication activities,scientific inquiry,practical activities,and small family experiments.The proportion of experiments in the teaching materials of the People's Education Press is the largest,and the proportion of thinking and communication and small family experiments accounts for a small proportion.Part ?:A comparative empirical study of typical experiments in chemistry textbooks for middle school and middle school.In this part of the study,the author chose the typical experiments in China and Singapore,such as the effect of concentration on the chemical reaction rate,the titration reaction,the sequence of metal activity,and the preparation,separation and purification experiments of salts.In secondary school teaching,the presentation of teaching experiment,the experimental implementation process and the experimental results are analyzed and compared,and the characteristics of the teaching materials in the two countries are drawn.The experimental characteristics of the Singapore teaching materials:more attention is paid to the design of inquiry questions;the experiment content has selected many new topics The more interesting and interesting experiment shows that the experiment can enhance the fun of chemistry;the experiment focuses on the way of presentation and embodies the design intention of applying the knowledge.The teaching characteristics of the teaching materials of the People's Education Press can be more centered on the students' learning and development,combined with the students'cognitive development rules and psychological development laws,and select appropriate teaching content,which better highlights the interest and practicality of teaching materials experiments.Sexuality and teaching materials of the People's Education Press have a certain degree of flexibility.They can adapt to all students and make other considerations to the students of arts and sciences,reflecting the spirit of humanistic care.Based on the above characteristics,we can draw lessons from it.Part ?:Lessons from the Singapore Experiment and Transformation in China.Contrastive Analysis of Typical Experiments of Chemistry Textbooks in China and Singapore.Based on some experimental design ideas or experimental devices in Singapore textbooks,three experiments in Singapore textbooks were selected to improve in China,hoping to have a certain reference for teachers' teaching.Part ?:Study conclusions and expectations.According to the overall comparison of the experimental compilation of the chemistry textbook for senior high school students in the third part of the two editions and the comparative empirical study of the fourth part of the typical experiment and the reference and the transformation of the Singapore experiment in the fifth part,this paper proposes some experiments on the Chinese middle school chemistry textbook.Some suggestions for the selection and teaching of high school teachers are mainly experimental life;experimental integration;experimental safety;experimental exploration.Based on the above suggestions,chemical experiment teaching can be further optimized.
