| 摘 要： | 研究学科领域知识丰富性不同的学生在问题表征过程中信息表征层次的特点。采用“学习-再认”范式，以5类等式为材料，62名初二学生参与实验。结果：两组被试对表面和原理特征一致的等式产生明显的错误再认；对表面特征不一致等式的错误率明显减少。无论原理特征是否一致，两组对表面特征一致等式的反应时无显著差别，但在正确率上丰富组的更高。说明，两组均以有序的系列加工方式编码信息，优先编码表面特征。贫乏组对原理特征的编码干扰表面特征的加工，因而原理特征被丢弃。丰富组加工表面特征则无干扰现象出现，两种特征均能作为再认线索。

| Abstract: | It has been established that learners with different abundance of domain knowledge focus on different aspects of problems,with the tendency that poor groups focus more on surface features rather than on principled features and rich groups focus on principled features.But the mechanisms that underlie these differences were less known.In the present study,the mechanisms of representational levels of students with different abundance of disciplinary domain knowledge were investigated in 5 categories secondary ... |
