This study developed a video playing system that incorporated two signaling devices, headings and table of contents, for supporting video learning and navigation. An experiment was conducted for understanding the effects of the system on learning and navigation performance of the immediate and delayed tests. Thirty participants were randomly…

With advances in technology, intelligent personal assistants (IPAs) have become available to assist users with a variety of tasks using voice commands. Because IPAs may induce dialogic interactions, researchers speculated that they may benefit second language learning, especially regarding pronunciation, listening and speaking skills. So far, very…

Android platform-based educational software for visually impaired students (VIS) are widely available, but very few of them are in Bangla. Due to the lack of low-cost Bangla Braille-based technologies, VIS depends on the traditional slate and stylus to learn Braille. This study proposes a Braille-based educational software, Bangla Braille Learning…

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…

Interaction is critical for successful teaching and learning in a virtual learning environment (VLE). This paper presents a web-based interaction-aware VLE--WebIntera-classroom--which aims to augment learning interactions by increasing the learner-to-content and learner-to-instructor interactions. We design a ubiquitous interactive interface that…

Using a computerized logic course employing the Carnegie Mellon Proof Tutor problem-solving environment, crucial features of computer environments were isolated and relative pedagogical effectiveness was assessed. Students used computerized environments to construct proofs and were presented with identical course materials on sentential logic. The…
