Implementing online technologies alone cannot ensure learning. A verified approach is needed to optimize the pedagogical effect of online learning. Previous studies have suggested that the application of the modality principle in multimedia design improves the efficiency of learning by reducing cognitive load. Nevertheless, this design approach…

The study was an investigation of online adult learners' perceptions of interaction, satisfaction, and performance within an online course using the Blackboard platform. Interaction included learners' interaction with the instructor, content, and the classmates. The effect of student background variables and course-related variables on interaction…

The present study was designed to identify the quality dimensions as perceived by adult learners who had taken one or more e-learning courses offered by higher education institutions in South Korea and to identify and confirm the structural features of these quality dimensions. The results of the exploratory factor analysis arising from a survey…

Effectively presenting complex material is a crucial component of instructional design within simulation-based training (SBT) environments. One approach to facilitate the acquisition of higher-order knowledge is to embed instructional strategies within the systems themselves. Currently, however, there are few established guidelines to inform…

Experienced teachers, tasked with mentoring, often find themselves inundated with large amounts of didactic information as they prepare for guiding new interns. In an effort to develop training that would both prepare new mentors and revitalize experienced mentors, a state Educational Professional Standards Board enlisted the help of instructional…

This article presents a quasi-experimental study comparing the impact of two technology-related teacher professional development (TTPD) designs, aimed at helping junior high school science and mathematics teachers design online activities using the rapidly growing set of online learning resources available on the Internet. The first TTPD design…

This article describes a blueprint for an online learning environment that is based on prominent instructional design and assessment theories for supporting learning in complex domains. The core of this environment consists of formative assessment tasks (i.e., assessment "for" learning) that center on professional situations. For each professional…
