A Situational And Functional Study Of Examples Of Primary School Mathematics Textbooks

Teaching material plays an important role in the process of classroom teaching.It is an important medium for teachers’ teaching and students’ learning.The quality of teaching materials has an important influence on the quality of teaching.Therefore,the research on the compilation of textbooks has received more and more attention.At present,a lot of scholars at home and abroad have done some research on primary school mathematics textbooks.But for example of mathematics teaching in the primary school is still relatively small,and to study the function of the example teaching is not deep enough,mining situation and function of the application of the example teaching needs to be improved.This is an urgent need to solve the problem of primary school mathematics textbooks.Based on this,this article has carried on the research to our country elementary school mathematics textbook example the situation and the function.The main contents and conclusions are as follows:1、The PEP,Beijing Normal University Press,Western version of the three versions of primary school mathematics textbook examples of situational analysis,through the analysis of the previous situation classification,and combining these three versions of its own characteristics,and the formation of the basic situation of classification.In this paper,the case context is divided into five categories:no context,personal life situation,social life situation,other subject situation,animation situation.2、Compare the three versions of textbooks in the examples of the contextual factors of the similarities and differences,summed up the situation of the distribution characteristics of primary school mathematics textbook examples:the life situation(including personal life situation and social life situation)is relatively high,followed by the ruthless environment,and animation situation and other disciplines situation is relatively low.3、The PEP,Beijing Normal University Edition,West three edition primary school mathematics textbook examples are analyzed,through the analysis of the previous classification function obtained by combining these three versions of its own characteristics,this paper formed the basis of the functional classification of examples.In this paper,the example function is divided into six categories:understanding the concept,consolidate knowledge,train thinking,training hands-on operation,exercise observation,solve practical problems.4、This paper summarizes the similarities and differences in the functional characteristics of the three versions of the textbooks.It summarizes the characteristics of the functional distribution of the examples of primary school mathematics textbooks:consolidates the knowledge category,followed by solving the practical problems,followed by understanding the concepts,thinking training,training hands-on and exercise Observation of four functions.5、First,the three version of the sample as a whole,and explore the relationship between the situational factors and functional factors.Then,we discuss the relationship between the situation and function of the sample and the knowledge domain.The results show that the function of the example has a positive correlation with the situation,that is,the more complex the situation is,the stronger the function of the sample.In addition,found no situation and consolidate the knowledge function of the highest correlation,indicating no situational examples is mainly used to consolidate the knowledge of other disciplines;and between context and exercise observation the lowest correlation,almost no correlation.6、The results of the above research and analysis of the conclusions and conclusions:① in the case of context settings,should be appropriate to reduce the proportion of cases without context,increase the number of other subject cases.② In the example function setting,the distribution of the example is basically reasonable in the function,but the type of function involved is less.Therefore,the future examples can be used to add some examples of other functions,such as cultivating the mathematical expression ability and team cooperation ability,Reading comprehension and so on.③ On the basis of this,this paper argues that it is necessary to enhance the relationship between life situation and thinking training,cultivate hands-on operation and exercise observation.
