基于元认知能力发展的智能导学系统研究

Study on Intelligent Tutoring Systems for Promoting the Metacognitive Ability Development

通过比较分析国际典型的7个智能导学系统,文章发现各系统之间存在教学法、心理学、技术和实用主义的差异,但在智能化程度和有效促进元认知发展方面具有相同点。之后,文章采用系统建模方法分析了学生的元认知策略,构建了ITS中的元认知能力模型。最后,文章以Betty’Brain系统为例,通过实证分析得出:元认知意识的智能导学系统不仅有利于促进学生元认知能力的发展,还能培养学生的问题解决能力。

Through comparing and analyzing seven international typical ITS（intelligent tutoring systems）, it found that there were differences in teaching methods, psychology, technology and pragmatism among the systems, but there were also similarities in aspects of intelligent degree and effective promotion in metacognition development. Thereafter, the paper analyzed students＇ metacognitive strategy employing system modeling method, and constructed the metacognitive ability model about ITS. In the end, the paper took Betty＇s brain system as an example to make an empirical analysis, and the results shown that metacognitive awareness of ITS can promote learners＇ metacognitive ability development and cultivate learner＇s problem-solving ability.
