An Empirical Test of Three Instructional Scenarios for Hypervideo Use in a Vocational Education Lesson

Recent technological advances are rekindling educational interest in hypervideo (HV). HV provides a good opportunity for enhanced teaching and learning thanks to its affordances for interactivity (advanced navigation control, hyperlinking with supplementary materials, and communication options). This study investigated how these functionalities can be employed in a vocational education context by examining the design of three prototypical HV lesson scenarios (expository, individual learning, and collaborative learning) and comparing their effectiveness with that of a traditional lesson. Effects on motivation and knowledge acquisition were assessed. Results indicated that the HV lessons supported learning more effectively than traditional lessons. On a delayed posttest, all experimental conditions scored significantly higher than the control condition. The special benefits of HV use for expository instruction are singled out for discussion. This study provides an encouraging starting point for scholars who would like to investigate the functional integration of HV in educational practices.     

A model for designing hypervideo-based instructional scenarios

In this article, we provide a conceptual model for the design of instructional scenarios integrating hypervideo as an instructional tool. The model provides a structural aid for making design decisions about using hypervideo in instruction. We start by introducing the theoretical rationale for hypervideo as a tool, exploiting three different interactivity functions. We then examine the cognitive and socio-cognitive theories that can inform the design and usage of hypervideo. Next, we present the instantiation of these functions and theories in a software interface, after which we present the model, which is based on the following two layers of design decisions: the first pertains to the interactivity features and the second is connected with the instructional strategy. Three main design steps are presented in the form of guidelines, corresponding to a preparation phase, a production phase, and a use phase. Finally, a set of cases exhibiting exemplary implementations of a hypervideo-based instructional scenario are described.
