目的以大学生为被试,探讨具有多重表征的不同特征材料对归类学习中运用策略影响以及随着表征数的增加,归类学习的难易变化趋势。方法采用两种不同特征的具有多重表征的学习材料,来探讨材料的特征及表征数对归类学习中运用策略和归类结果的影响。结果材料的特征影响归类策略的使用。材料的表征数不影响归类策略的使用,但影响归类学习的结果。当运用规则策略进行归类时,随着表征数的增加,归类学习变得困难。当运用样例策略进行归类时,随着表征数的增加,归类学习变得容易。结论具有多重表征的不同特征材料的确对归类学习中运用策略产生影响。
The purpose of this study was to investigate the impact of different characteristics of multiple signatures on the use of strategies in classified learning and the tendency of categorical learning as the number of signatures increased. Methods Two learning materials with different characteristics and multiple representations were used to explore the effect of material characteristics and number of representations on the utilization strategies and classification results in classified learning. The characteristics of the resulting materials affect the use of categorization strategies. The number of characterizations does not affect the use of categorization strategies, but affects the results of categorical learning. As rules are used for categorization, categorical learning becomes difficult as the number of representations increases. When using sample strategies for categorization, categorical learning becomes easier as the number of representations increases. Conclusions Different characterizations with multiple signatures do have an impact on the strategies used in categorical learning.
