Design Solutions for Interactive Multi-video Multimedia Learning Objects
The increasing popularity of distance education courses, including Massive Open Online Courses (MOOCs), creates a demand for the production of quality video-based educational material. In order to reduce the costs involved in the production of video lectures, several researchers have investigated alternatives for capture and access systems which automatically capture lecture contents to generate corresponding video lectures. We also developed a system for this purpose; however our system generates Interactive Multimedia Learning Objects (iMLO) instead of a traditional (linear) video lecture. The iMLO’s features and its interface are important issues for the development of the capture and access system. Interface aspects, such as which are proper ways to present content for users and which navigation facilities are more useful, are distinctive requirements and may impact the user experience. In this paper we present a novel design for the iMLOs which results from an evolution process supported by feedbacks from the main stakeholders: students and lecturers. The feedbacks have been acquired by analyzing the interaction of students with the iMLOs in real scenarios. Based on these feedbacks, we have identified several design implications. We present the proposed interfaces and proof-of-concepts implementations and report lessons learned during the development of the final design solution, which can guide other designers in the conception of new iMLOs. The whole process is documented by means of Design Rationale.
