Guidance can help learners overcome the difficulties of getting started in a novel domain, but it is often ineffective in promoting learning and transfer. This article examines two aspects of guidance--communicating solution strategies for a problem domain and providing working memory support--in learning a novel problem-solving skill. Subjects in two experiments learned to troubleshoot simulated information networks. The learning environment varied in type of guidance provided--none, variable template, fixed template, and procedural instruction--and in availability of memory aiding. Variable-template guidance was effective when memory aiding was provided, and procedural instructions produced effective learning with or without memory aiding. However, fixed-template guidance was not effective, and there was no consistent effect of memory aiding in unguided, discovery learning conditions. The results have theoretical implications for the locus of guided-learning effects and suggest practical guidelines for the design of guided-learning environments.
指导可以帮助学习者克服在新领域入门时遇到的困难,但在促进学习和迁移方面往往效果不佳。本文研究了指导的两个方面——传达问题领域的解决策略和提供工作记忆支持——在学习一种新的解决问题技能中的作用。两项实验中的受试者学习对模拟信息网络进行故障排除。学习环境在提供的指导类型(无、可变模板、固定模板和程序指令)以及记忆辅助的可用性方面有所不同。当提供记忆辅助时,可变模板指导是有效的,并且无论有无记忆辅助,程序指令都能产生有效的学习效果。然而,固定模板指导并不有效,并且在无指导的发现学习条件下,记忆辅助没有一致的效果。这些结果对指导学习效果的位置具有理论意义,并为指导学习环境的设计提出了实用指南。
