WebCT, a web-based virtual learning environment (VLE) and Interactive TV (ITV) are relatively new technologies that are used to deliver distance education at the Faculty of Health Sciences, Stellenbosch University. This study explores how effective current approaches to instructional design and interaction have been in utilizing these two technologies to support interaction and what lessons can be learnt. Five focus-group interviews were held with students and lecturers to assess the perceived quality of student-lecturer/student-student interactions. All students were invited to complete a questionnaire at the end of every module to assess their perceptions of interaction. Interaction was highly valued by students and lecturers participating in distance-learning programmes utilizing either VLE or ITV. Students rated courses using both technologies as moderately interactive. Significant differences between VLE and ITV were detected in student-lecturer and student-student interactions, use of additional modes of communication, instructional design, technological interactivity and social rapport activities. The groups did not differ across a number of likely barriers to interaction and both also reported the need for more flexible and better paced instructional designs.
WebCT，一种基于网络的虚拟学习环境（VLE）以及交互式电视（ITV），是相对较新的技术，被用于斯泰伦博斯大学健康科学学院开展远程教育。本研究探讨了当前的教学设计和互动方法在利用这两种技术来支持互动方面的效果如何，以及可以吸取哪些经验教训。与学生和讲师进行了五次焦点小组访谈，以评估师生/生生互动的感知质量。在每个模块结束时，邀请所有学生填写一份问卷，以评估他们对互动的看法。参与使用VLE或ITV的远程学习课程的学生和讲师都高度重视互动。学生对使用这两种技术的课程的互动性评价为中等。在师生互动和生生互动、额外沟通方式的使用、教学设计、技术交互性以及社交融洽活动方面，VLE和ITV之间存在显著差异。在一些可能的互动障碍方面，两组没有差异，并且两组都报告需要更灵活、节奏更好的教学设计。
