论文摘要
我们描述了一项关于使用在线实验室用于自我指导学习的研究，该研究是通过构建和模拟生态系统的概念模型来进行的。在这项研究中，我们只能观察到建模行为和结果。学习目标和结果尚不清楚。我们使用机器学习技术来分析他们生成的315名学习者和822个概念模型的建模行为。我们从结果得出三个主要结论。首先，学习者表现出三种类型的建模行为：观察（集中模拟），构造（集中施工）和完整的探索（模型构建，评估和修订）。其次，尽管观察是所有学习者中最常见的行为，但没有评估的施工对于较少参与的学习者而言更为普遍，并且全面探索主要是针对更多参与的学习者。第三，探讨了模型构建，评估和修订的完整周期的学习者产生了更高质量的模型。这些建模行为为整个自我指导的学习提供了见解。
We described a study on the use of an online laboratory for self-directed learning by constructing and simulating conceptual models of ecological systems. In this study, we could observe only the modeling behaviors and outcomes; the learning goals and outcomes were unknown. We used machine learning techniques to analyze the modeling behaviors of 315 learners and 822 conceptual models they generated. We derive three main conclusions from the results. First, learners manifest three types of modeling behaviors: observation (simulation focused), construction (construction focused), and full exploration (model construction, evaluation and revision). Second, while observation was the most common behavior among all learners, construction without evaluation was more common for less engaged learners and full exploration occurred mostly for more engaged learners. Third, learners who explored the full cycle of model construction, evaluation and revision generated models of higher quality. These modeling behaviors provide insights into self-directed learning at large.
