| Explanatory writing is a special type of writing in primary school.Its strict structure and accurate expression are beneficial to the improvement of students’ thinking ability and language logic.However,the investigation shows that there are some problems such as inadequate preparation before class,modelization of classroom teaching and unification of review after class.It is a knowledge processing tool that strengthens the visual representation effect and drives the thinking visualization.It outlines the knowledge and information processing contents in different thinking modes.It is beneficial for teachers to improve the teaching efficiency of explanatory text based on thinking map.Based on the theory of knowledge visualization,cognitive psychology and constructivism,this research mainly explores the application of thought map in the teaching design of third paragraph of Chinese.First of all,the author integrates the former theoretical research and empirical research from the perspectives of "Thinking Map" and "Primary Chinese Explanatory Text Teaching".Secondly,according to the basic structure of the method of practice,the author constructs the basic structure of teaching design of the third paragraph of elementary school language based on thinking map.Finally,the author qualitatively understands the teaching effect of thinking map by questionnaire,and pays attention to the value of students’ thinking ability in explaining writing and reading.The results show that thinking map is a new teaching tool for teachers.It can be used as a pre-study stage to organize the knowledge,for example,in order to get a preliminary understanding of the knowledge learned in class.At the same time,the bridge diagram and circle diagram can also be used in the imitation of sentences and explanatory texts,which can consolidate and expand the contents of the study.This also proves that the application of thinking map in primary school Chinese explanatory text teaching is effective.Therefore,the thought map has certain application value in the teaching of Chinese explanatory writing in primary schools,and its great educational potential still needs our further efforts and development. |
