Abstract:

In order to overcome the shortage of cluster analysis which often bias the choice of a solution and the lack of statistical indices to assist in the choice of a final solution, the current study use latent profile analysis to study types of social support of junior middle school students. Beside, we also use discriminate analysis to validate the accuracy of the classification that use latent profile analysis to class types of social support. On the other hand, we not only study the relationship between social support, learning motivation, learning strategy, academic performance from the variable level. But also analyze the effect of different types of social support on learning motivation, learning strategy, academic performance from the perspective of individual differences. 374 junior middle school students are selected form one middle school to attend the questionnaire survey which includes perceived social support scale, motivated strategies for learning questionnaire and learning Motivation Scale. Students’ performances are measured by their mid-term test scores.

Key words: social support, latent profile analysis, discriminate analysis, learning motivation, learning strategy

摘要：

利用潜在剖面分析法和辨别分析法对374名初中生社会支持的类型进行考察，探讨不同社会支持类型初中生的特点，分析社会支持类型对学习动机、学习策略、成绩的影响。结果表明：（1）初中生社会支持分为亲密无间型、若即若离型和家庭疏远型3种。（2）亲密无间型初中生的社会支持最高，家庭疏远型初中生的社会支持尤其是家庭支持最低，而若即若离型初中生的社会支持处于亲密无间型和家庭疏远型之间。（3）社会支持类型对学习动机、学习策略、成绩有显著影响。
