The Research On The Junior Middle School Students’ Learning Disorder About Chemical Calculation

Chemical calculation is an important part of junior high school chemistry, butalso an important content of Suzhou senior high school entrance examination,students learning process calculation in chemistry, can cultivate the thinking abilitygradually, the ability to analyze problems, to solve the problem. Chemical calculationprocess of learning is a comprehensive understanding and application of chemicalconcepts, principles, not mathematical operation simple, also is not simple skill copy.Chemical calculation is one of the main difficulties in junior middle school chemistrylearning, students often feel be at a loss what to do in the face of chemical calculation,learning disabilities.In this paper, on the basis of existing research, the learning theory and chemistrycalculation error study together, the knowledge questionnaire and computationalchemistry learning questionnaire investigation was conducted to study the chemicalcalculation, a secondary school in Jiangsu104middle school students as the researchobject, and combining with the survey of the4students the case interview. Throughthe statistics of the questionnaire, summed up the main obstacle in junior middleschool chemistry study has: affective disorder, dyslexia, impaired memory, thinkingobstacles and learning adaptability obstacle; analysis of main causes of ComputationalLearning Disabilities Junior Chemistry are: lack of chemistry calculation of interest inlearning, not thinking independently, the relevant chemical knowledge not firm, thereis a psychological fear. According to the research results, chemical elimination givesthe calculation of learning disabilities teaching suggestions: to create interest, improvethe calculation of reinforcement learning self-confidence to overcome the fear ofpsychological, foster independent thinking ability development thinking potential,clear thinking, construction of chemical knowledge network conditions.Because of time constraints and teaching schedule and other reasons, the juniormiddle school chemistry calculation fails to conduct a comprehensive study,calculation of solubility and not included in the survey by chemical calculation;learning disability or other reasons, these need to be improved in further research.
