The development of a learning environment that integrates 'learning by modeling' and 'learning from errors'

我们实现了一个“从建模中学习”和“从错误中学习”相结合的建模学习环境，并对其有效性进行了评估。开发了两项关键技术：(1)健壮的模拟器，即使错误的模型包含违反约束的情况，它也可以计算错误模型的行为；(2)约束的语义，它系统地描述了约束的物理含义，并为解释模型的非自然行为提供了启发式方法。这些技术促成了新的建模学习环境，该环境结合了“从建模中学习”和“从错误中学习”两种教学方法的优点。一项初步实验表明，它在学习科学方面很有前途。

We have implemented a model-building learning environment which integrates 'learning through modeling' and 'learning from errors,' and evaluated its effectiveness. Two key technologies are developed: (1) the robust simulator which can calculate the behavior of an erroneous model even if the model includes constraint-violation, and (2) the semantics of constraints which is a systematic description of physical meanings of constraints and provides heuristics for explaining the unnatural behavior of models. These technologies enabled the new model-building learning environment which combines the merits of both 'learning through modeling' and 'learning from errors' pedagogy. A preliminary experiment suggested it is promising in in learning science.
