This study describes the TPACK-Developing Instructional Model which prescribes an instructional process for developing pre-service teachers' Technological Pedagogical Content Knowledge (TPACK) during the instruction of Information and Communication Technology (ICT) tools. This model proposes three phases for developing teachers' TPACK through ICT…

This study investigates the different effects of web-based and face-to-face discussion on computer engineering majors' performance using the Karnaugh map in digital logic design. Pretest and posttest scores for two treatment groups (web-based discussion and face-to-face discussion) and a control group were compared and subjected to covariance…

Within the field of education, there has been an increasing recognition of the importance of formative assessment and of structural knowledge. In an effort to fill needs in each of these areas, this article describes an innovative feedback strategy intended to improve students' structural knowledge. Twenty-four high school physics students were…

This experimental investigation replicates previous investigations of the effects of left margin screen background color hue to signal lesson sections on declarative knowledge and extends those investigations by adding a measure of structural knowledge. Participants (N = 80) were randomly assigned to receive 1 of 4 computer-based lesson treatments…

When visualization tools utilized in computer programming education have been evaluated empirically, the results have remained controversial. To address this problem, we have developed a model of short-term effects of program animation, and used it in a series of experiments. In the current experiment, we varied visual representation of an…

Instructors who use computer-generated graphics in their lectures have many options to consider when developing their presentations. Experts give different advice on which typefaces, background and letter colors, and background imagery improve communications. This study attempted to resolve these controversies by examining how short-term recall of…

Describes "Glass-box Interpreter" a low-level program visualization tool called Bradman designed to provide a conceptual model of C program execution for novice programmers and makes visible aspects of the programming process normally hidden from the user. Presents an experiment that tests the efficacy of Bradman, and provides…

Presents a study of integrated computer technology which incorporates pace-controlled syntactic chunking in a captioned video presentation. In addition to increasing student motivation and learning efficiency over time, the program supplied the least able students with the means to better understand and respond to foreign language discourse. The…

Compares the effectiveness of textual feedback to video feedback during two computer-assisted biology lessons administered to secondary students. Lessons consisted of a brief text introduction followed by multiple-choice questions with text or video feedback. Findings indicated that video feedback resulted in superior learning and comprehension,…

Reports the use of two different visual-control treatments (self-controlled versus system-imposed) among students with different cognitive styles (Field Independent and Field Dependent). Eighth-grade students were tested to determine how they learned from different design approaches of animated instructional materials. Effect of visual control was…

Investigates the effects of audio and text density on the achievement, time-in-program, and attitudes of 134 undergraduate students. Data concerning pre-existing computer skills/experience and demographic information were also collected. Findings have implications for the use of audio, text and graphics in the design of computer-based instruction.…

Investigates the effects of computer-assisted video-based anchored instruction on promoting students' attitudes toward mathematical instruction and problem-solving skills. Examines the effects of different media attributes on students' mathematical achievement and attitudes in a situated learning environment. Findings suggest that anchored…

The purpose of this experimental study was to test the role of image and animation on: a) learners' perceptions of pedagogical agent persona characteristics (i.e., extent to which agent was person-like, engaging, credible, and instructor-like); b) agent value; and c) performance. The primary analysis consisted of two contrast comparisons: 1)…
