Research On The Variant Teaching Of Mathematics Exercise Lesson In Junior Middle School Under The Core Literacy

Variant teaching is a traditional feature of teaching in China,and is applied consciously or unconsciously by front-line teachers.Variant teaching has been popular in China for a long time because it is adapted to the national conditions of teaching methods that combine large class teaching with lectures in Chinese education,and is in line with modern new curriculum reform.At present,with the proposal of the domestic core literacy of mathematics and the release of new curriculum standards,education experts point out that the core literacy of mathematics refers to the thinking character and key ability to adapt to the lifelong development of the individual and social development,which makes how to implement the core literacy in the classroom.The focus of attention is that variant teaching is a common method of numeracy learning problem classes in junior high school,and a good carrier for students' core literacy.Therefore,the focus of this research is to use variant teaching in exercise classes to cultivate core literacy in mathematics.The author combined with his personal practical experience in a middle school in Hengyang City and through the reading of a large number of documents,it is found that although the current practice class is widely used,teachers only pay attention to the variation of the problem,but do not understand why it should be changed,how to change it reasonably and better.Based on this situation,the author began to conduct theoretical research,strategic research and practical exploration.First of all,the literature method was used to clarify the value of variant teaching research,the current research progress,and define the variant,mathematics variant teaching,mathematics core literacy,mathematics core Accomplish relevant concepts such as variant teaching in exercise classes,and find theoretical support for variant teaching from philosophy,psychology,and pedagogy.Secondly,carry out strategic research on the core literacy of junior high school variant teaching.From topic selection,creating scenario scenarios,using teaching methods to after-class reflection,teachers can find ways to cultivate core literacy from these four teaching links;then,summarize the commonly used variant methods in the problem class(solution variants and topic changes)The following points should be paid attention to in the classroom:grasping the degree and quantity of the transformation,creating a classroom atmosphere conducive to the transformation,and selecting the appropriate transformation method,these will pave the way for practical research.Finally,carry out practical exploration on variant teaching.According to the actual situation of the author's internship,combined with the strategy of cultivating core literacy inthe exercise class,two exercise classes "Parallel quadrature property development-" M "type graph," U "type graph and" integral addition and subtraction " The study of course examples hopes to provide some valuable references for front-line teachers to cultivate students' core qualities of mathematics in the geometry and algebra problem classes.
