Attribution Analysis And Teaching Case Study Of Chemistry Learning Disabilities Of High School Students In County Town

The degree of urbanization of county towns lies between cities above the city level and rural towns.The development of county schools plays an important role in the cultivation of talents and social development in our country.This paper focuses on the teaching of central science--chemistry in high school,and takes Chaling Grade 2020 as an example to carry out a study on learning disabilities of high school students in chemistry learning,and designs teaching cases of iron,sodium and their compounds.This study first analyzes two conditions to determine the freshman entrance exams in the book of learning disabilities are chemical required first mainly: ion and ionic equation,REDOX reaction in the law,and its compound and sodium metal materials in knowledge remember,material in the synthetic computation of the amount of logical thinking ability is poor,hard to microscopic structure and elements of the macroscopic properties of the element.In learning disabilities of freshman in attribution analysis,this article mainly adopted the questionnaire method,through to the freshman in chemistry learning motivation,performance,and environmental influence students' questionnaire survey,induces the forming cause of chemistry learning disabilities students in their own ways,found that some students lack of improper use of chemical learning motivation,learning method,learning habit is not correct,senior students lack of thinking in terms of exercise,the failure due to their lack of ability,such as peer pressure under the new environment.Through observation and interview,teachers were found to be overly dependent on multimedia equipment,too far away from students,too little communication and encouragement,and too little attention to chemistry experiment teaching.In addition,family,school and class also have certain positive and negative effects on students' chemistry learning.In the attribution analysis,researchers have analyzed the negative effects of these aspects,and emphasized in the measures how school,class and family should strengthen the positive influence on students' chemistry learning.Based on the above investigation and analysis,it is suggested that teachers should pay more attention to five points: attach importance to the teaching of chemistry experiments,attach importance to the cultivation of problem-solving thinking,attach importance to the teaching of learning methods,attach importance to the construction of their own teacher's ethics,and attach importance to assisting students in correct attribution.Also put forward certain requirements to parents and schools.Finally aimed at students in iron and its compounds are easy to remember on the knowledge of confusion,remember learning disabilities has designed two teaching cases,the case through the let students improve price-class 2 d figure to help students to build on the knowledge network of iron and its compounds,second case by iron and sodium contrast teaching,make students understand the general order of metals and their compounds,deepen the impression of iron and its compounds knowledge points.
