Development and Validation of a Case Study Approach to Teaching Human-Computer Interaction

先前的概念验证项目已经开发了一组可用性工程案例研究的原型，一个案例浏览工具，以及几个基于案例研究的课堂活动。这项工作与编写和出版新的人机界面本科生教科书(Morgan Kaufmann，2002)进行了协调。这本教科书与目前的教材有很大的不同，将人机界面内容的呈现与基于场景的交互系统开发的全面框架相交错。新教材的一个关键创新是使用了案例研究来介绍和举例说明分析、设计和评估框架。概念验证项目通过开发更丰富和更灵活的在线材料，以及从另外三个问题领域构建案例，增强了书中提供的案例研究材料。该项目提交给CCLI-EMD轨道，进一步开发和验证案例研究作为人机对话教学要素的学习效果。利用Morgan Kaufmann的营销渠道，我们从8-10所其他大学招聘有兴趣使用这本书的教授和学生，并参与案例研究材料的评估。我们与这些教师和学生一起开发新的活动，并将原型活动打包以便于使用。我们还改进了浏览工具，响应在原型项目期间收到的形成性评估，并添加了新的功能，以支持在整个生命周期中关注的可跟踪性，更灵活的视图和案例研究报告方案，以及专家和学生的创作。该项目利用我们正在进行的基于情景的开发方法的研究，将方法论概念融入本科教育。它还强调了在本科教育中使用信息技术，以获取内容和支持学生项目。开发案例研究的研究生正在成为展示和说明基于情景的框架的专家，帮助他们为在人机界面教育领域的职业生涯做好准备。

A prior proof of concept project has developed a prototype set of usability engineering case studies, a case browsing tool, and several classroom activities based on the case studies. This work was coordinated with the development and publication of a new HCI undergraduate textbook (Morgan Kaufmann, 2002). The textbook differs dramatically from current offerings, interleaving the presentation of HCI content with a comprehensive scenario-based framework for the development of interactive systems. A key innovation of the new textbook is its use of a case study to introduce and exemplify the analysis, design, and evaluation framework. The proof of concept project enhanced the case study material presented in the book, by developing richer and more flexible online materials, and by building cases from three additional problem domains. This project, submitted to the CCLI-EMD track, further develops and validates the learning effectiveness of case studies as an element of teaching HCI. Using the marketing channels of Morgan Kaufmann, we recruit professors and students from 8-10 other universities interested in using the book, and participating in the evaluation of the case study materials. We work with these instructors and students to develop new activities, as well as packaging the prototype activities for convenient use. We also refine the browsing tool, responding to formative evaluation received during the prototype project, and add new functionality to support traceability of concerns throughout the life cycle, more flexible views and case study reporting schemes, and authoring by both experts and students. This project leverages our ongoing research on scenario-based development methods, incorporating the methodology concepts into undergraduate education. It also highlights the use of information technology in undergraduate education, for both content access and student project support. The graduate students who develop the case studies are becoming experts in presenting and illustrating the scenario-based framework, helping to prepare them for careers in HCI education.
