UIUC虚拟光谱仪（UIUC-VS），一个交互式的，基于Java的仿真和教学系统的开发进行了讨论。学习的学徒模式被用来创建一个学习环境的一维质子核磁共振（NMR）实验的研究，与理论知识与实际操作经验相结合的目标。主动、探索、学徒式的学习通过系统内的操作模式得到支持。学生可以灵活选择“观摩专家”操作和讲解操作步骤，也可以“当学徒”自主操作。学生可以自由切换模式，让他们控制系统干预的水平。学生还可以探索和反思对象，程序和相关概念的“信息空间”。UIUC-VS使用基于Java的Web技术扩展了以前的教程应用程序LEMRS，1，为NMR教学的共享模拟环境提供了基础。作为一个计算机支持的协作学习环境，该系统包括一种异步通信方法，学生可以在“问题板”上发布问题和评论，并能够通过屏幕截图上的注释捕获系统的当前状态。涉及本科化学学生的形成性评价是系统重新设计的关键。
The development of the UIUC Virtual Spectrometer (UIUC‐VS), an interactive, Java‐based simulation and tutoring system, is discussed. The apprenticeship model of learning is utilized to create a learning environment for the study of a one‐dimensional proton nuclear magnetic resonance (NMR) experiment, with the goal of linking theoretical knowledge with practical operational experience. Active, exploratory, apprentice‐style learning is supported via modes of operation within the system. Students can flexibly choose to “observe the expert” perform and explain operational steps, or “act as an apprentice” and carry out the steps autonomously. Students can switch between modes at their discretion, giving them control of the level of system intervention. Students can also explore and reflect on an “information space” of objects, procedures, and related concepts. UIUC‐VS extends a previous tutorial application, LEMRS,1 using Java‐based, Web‐capable technologies to provide a basis for a shared simulation environment teaching NMR. As a computer‐supported collaborative learning environment, the system includes a method of asynchronous communication, where the student can post questions and comments to a “question board,” with the ability to capture the current state of the system via annotations on a screen capture. Formative evaluations involving undergraduate chemistry students were crucial to system redesign.
