Interactive multimedia learning environments incorporate interactive features, such as questioning, through which questions are posed to students and feedback is delivered on their answers. An experiment was conducted comparing two forms of questioning. The participants learned about geology with a multimedia environment that included questioning…

This study reports the effects of different types of instructional preparation strategies on the problem solving performance of college students taking an introductory physics class. Students were divided into four equally skilled groups and solved the same physics problems after receiving different instructional preparations (engaging in…

In two experiments, we investigated predictions of the "collaborative theory of language use" (Clark, 1996) as applied to instant messaging (IM). This theory describes how the presence and absence of different grounding constraints causes people to interact differently across different communicative media (Clark & Brennan, 1991). In Study 1, we…

Data were collected by using: a) Turkish EFL Students' Background Survey, b) interviews at the beginning and end of the term, c) first and revised drafts, and d) end-of-semester Questionnaire. The…

Prompted by a previous study investigating the effects of pacing on the academic testing performance of college students with AD/HD, we further explored our preliminary findings, which suggested that a computerized testing environment enhanced the testing performance of college students with AD/HD. We compared the effects of a computerized vs.…

This comparative study was designed to investigate how online and traditional face-to-face (FtF) students used different learning styles in a graduate educational course. A nonequivalent control group design was employed. The study involved 19 students in an experimental group (online section) and 25 students in a control group (FtF section) in a…

In two experiments, students overheard two computer-controlled virtual agents discussing four computer literacy topics in dialog discourse and four in monologue discourse. In Experiment 1, the virtual tutee asked a series of deep questions in the dialog condition, but only one per topic in the monologue condition in both studies. In the dialog…

Although substantial literature exists regarding learning with visuals, most consider text the primary channel with varying amounts of visuals explored as a secondary channel. This study considered the effectiveness of visuals-only procedural guides versus visuals plus added text, using visuals as the primary channel and using visuals developed…
