Importance of Interface Design in e-Learning Tools
This chapter discusses a number of issues pertaining to interface design in e-Learning Tools (ELTs)—where ELTs refer to computer-based software that mediates and supports learners’ engagement with educational information. The design of the interfaces of ELTs involves two main components: representation and interaction. This chapter discusses eight issues that need to be considered when designing and evaluating ELTs: 4 regarding representation design and 4 regarding learner-information interaction design. The issues of representation design are: (1) selecting, (2) coupling, (3) encoding, and (4) scaffolding. The issues of interaction design are: (1) focus, (2) flow, (3) multiplicity, and (4) compositeness and externalization. Each of these is discussed and one study involving a tool is presented for each issue to highlight the importance of paying attention to that issue when designing and evaluating the interface of ELTs.
