Experimental Research On The Cultivation Of Analogical Reasoning Ability In Mathematics “Ratio” Unit Teaching In Primary School

Since the national basic education reform,the cultivation of pupils’ Analogical reasoning ability has gradually attracted the attention of educators.Under the background of “Double Reduction” policy,cultivating students’ Analogical reasoning ability is of great significance to improve teaching efficiency.The mathematics curriculum standard for compulsory education(2011 Edition)also clearly puts forward the requirements for the cultivation of analogical reasoning ability.Analogical reasoning ability will be the ability that students must have.How teachers cultivate students’ Analogical reasoning ability will be pushed to the peak of the wave of mathematics education.The sixth grade students have a good knowledge reserve and preliminary analogical reasoning ability.The “Ratio” unit is the content of the sixth grade and includes three types of analogical reasoning.The teaching material of the “Ratio” unit also involves the content of analogical reasoning.Therefore,the “Ratio” unit is selected for research.This study takes the students of class 9 and class 10 of grade 6 of W primary school in L City and all the mathematics teachers of grade 6 as the survey object.Through the test of the students’ Analogical Reasoning Ability of the two classes,we can understand the students’ current level of analogical reasoning ability;Interview all sixth grade mathematics teachers to understand the cultivation of students’ Analogical Reasoning Ability in the “Ratio” unit.Then it divides the level of students’ Analogical reasoning ability,arranges the interview results of teachers,and finds that: the level of students’ Analogical reasoning ability is low as a whole;Teachers lack the understanding of analogical reasoning,and the teaching ability of analogical reasoning in “Ratio” unit is weak.In view of the problems found,this thesis analyzes the causes,and puts forward the teaching strategy of cultivating students’ Analogical Reasoning Ability in the “Ratio” unit teaching: pre-school teachers should clarify the connotation of analogical reasoning;Grasp the requirements of Analogical Reasoning Curriculum Standard;Sort out the knowledge of analogical reasoning teaching materials.In the “Ratio” unit teaching,we should present a complete analogical reasoning teaching process;Combing the knowledge system of “Ratio”unit and strengthening the connection between analogy sources and new problems;Explicit education of analogical reasoning method.Then the teaching design of “Ratio” unit is carried out and the teaching experiment is carried out.The control class is taught according to the original teaching plan,and the experimental class is taught with the strategy of cultivating the ability of analogy and reasoning in the “Ratio” unit.After the teaching experiment,the post test papers are distributed in the two classes to recover and sort out the data.The study found that after teaching,the number of people with high level of analogical reasoning ability in the experimental class was higher than that in the control class.Specifically,the number of people who can carry out correct analogical reasoning increased.Therefore,the strategy of cultivating students’ Analogical reasoning ability in “Ratio” unit given in this study can improve students’ Analogical reasoning ability.
