有序思维模型对高三学生同分异构体分析能力发展的影响——二氯代物同分异构体数目分析

Influence of Orderly Thinking Model on the Development of Isomer Analysis Ability of Senior Three Students:Analysis of the Number of Isomers of Dichlorides

进行二氯代物同分异构体分析时,思维无序、重复计算是学生一直以来的痛点。本研究构建了一种有序思维模型,并采用描述统计、推断统计,研究了该思维模型对高三学生二氯代物同分异构体分析能力发展的影响,涉及简单和较复杂共2个水平层次有机物的二氯代物种数分析的教学即时效果和保持效果。此外,还调查了学生运用该模型时的心理体验。结果显示,有序思维模型对提高学生分析较复杂有机物的二氯代物种数的能力起到显著的教学即时效果和保持效果。学生思维的有序性得到加强。心理体验方面,学生面对二氯代物种数分析时的信心明显增强。本研究对学生解决类似程序性的任务有一定的借鉴意义。

In the analysis of isomers of dichlorides,disordered thinking and repeated calcula-tion have always been the pain points of students.In this study,an ordered thinking model was constructed,and descriptive statistics and inferential statistics were used to study the influence of the thinking model on the development of the analysis ability of isomers of dichlorides in senior three students.The teaching instant effect and retention effect of dichlorinated species number a-nalysis of simple and complex organic matter at two levels were involved.In addition,the psy-chological experience of students in using the model was investigated.The results showed that the ordered thinking model had a significant teaching instant effect and retention effect on impro-ving students'ability to analyze the number of dichlorinated species of more complex organic matter.The orderliness of students'thinking was strengthened.In terms of psychological expe-rience,students'confidence in the analysis of dichlorinated species was significantly enhanced.This study has certain reference significance for students to solve similar procedural tasks.
