基于组件的虚拟实验室反馈模型

提出了一种基于组件的虚拟实验室反馈模型. 该模型针对虚拟实验室中的实验设备以组件形式实现的特点, 把实验流程的拓扑结构以及实验设备的参数转换为有特定含义的字符串, 同时建立一个实验参照库, 库中预存好标准实验流程字符串, 用户实际搭建的实验流程字符串与库中的预存字符串进行模式匹配, 从而根据匹配结果给出实验指导意见. 该模型满足了学习者在虚拟实验过程对于纠错指导和效果评价的需求, 为改善学习者的使用体验提供了一种解决思路.

Feedback Model for Componented-based Virtual Laboratory

This paper proposes a feedback model for virtual laboratory based on components. Because of the feature of virtual laboratory based on components, we transform the experimental procedure and device parameters into specific strings firstly. At the same time, the experimental reference library including standard experimental procedure strings has been established. Then, the experimental procedure strings of users actually are built and the standard experimental procedure strings of the experimental reference library including execute the pattern matching. According to the results based on the pattern matching, experimental guidance will be given to the users. This model meets the needs of learners for evaluation and guidance in correcting during virtual experiment, and also provides a solution idea for improving learner's experience.
