Teachers are often perplexed realizing students ending up with different understandings of the same lesson after attending the same class. This study investigates the use of Variation Theory as a pedagogical design tool in improving students' problem-solving skills in trigonometry. This action research utilizing the 'Learning Study' approach was…

There is abundant educational research indicating that graphic organisers (knowledge maps, concept maps, or mind maps) have a beneficial impact on learning, but hardly any research has examined this in the context of presentations. This study therefore investigated how graphic organisers -- as delivered via presentation software -- affect learning…

Universities are trending towards displacing traditional printed textbooks (p-books) with electronic textbooks (e-books), even though an incomplete body of knowledge exists about the learning value of using e-books as instructional materials. As a result, this dissertation study was conducted to determine if digital textbooks are as…

The main focus of this paper is research on the content dimension of feedback, although the scheduling of feedback in an instructional program is also briefly considered. The two major categories of the content of feedback discussed are motivational, reinforcing feedback and informative, corrective feedback. It is noted that researchers in the…

Crucial, technologically oriented issues currently facing educators are addressed in the following 11 articles: (1) "The Definition of Educational Technology: An Emerging Stability," by Donald P. Ely; (2) "Media Applications to Instruction: Current Theoretical Considerations," by Gerald M. Torkelson; (3) "The Dilemma of…

Current issues in educational communications and technology are addressed in this collection of 48 papers, in which research reports predominate. Topics discussed include factors related to the learner, e.g., field dependence/independence, learning strategies, information processing, spatial ability, cognitive style, and cognitive strategies.…

This study compared the effects of an elaborated unit of instruction and a hierarchical unit on students' online processing activities, efficiency of encoding new information, and facility in solving problems. Participants were six education graduate students rated as novices on the to-be-learned content--a unit on the principles of photography.…

Describes study designed to examine the effects of textual and/or computer animated orienting strategies and practice on rule-using and problem-solving skills of elementary school students using computer-assisted instruction. Four different versions of a lesson based on Isaac Newton's Law of Motion are described, and results are analyzed. (28…

A study of 228 undergraduate psychology students examined the effectiveness of a prototype of "heatlab," a laboratory simulation written in PCE-PROLOG, intended for remedying misconceptions of the concepts "heat" and "temperature." The effect of varying the amount of structure on students' understanding and the…

Current issues in educational communications and technology are addressed in this collection of 47 conference papers in which research reports predominate. Topics discussed include factors related to the learner, e.g., learning strategies, information processing, spatial ability, cognitive style, and cognitive strategies. Presentation format and…

Many basic skills are chains of cognitive operations. For teaching such skills, two questions have not been adequately investigated: (1) how the operations comprising the skill should be sequenced, and (2) the relationships among the operations that need to be taught. This investigation entailed four studies on different types and lengths of basic…

The effects of teaching with analogies on students' conceptual understanding and explanations of educational computing were examined with three groups of preservice teachers in a computer literacy course. Students who were taught using complete analogies were found to have a better grasp of computing concepts than those taught using undeveloped…

Current issues in educational communications and technology are addressed in this collection of 35 papers, in which research reports predominate. Topics discussed include factors related to the learner, e.g., field dependence/independence, reading ability, learning strategies, and cognitive style. Presentation format and media and stimulus…

To examine the role of elaborations in learning a procedural skill (i.e., using a personal computer) from an instructional text, 88 members of the Carnegie-Mellon University community (students, faculty, and staff members) participated in two experiments. Experimental sessions consisted of a reading period followed by a task performance period in…

This research project was designed to explore ways of making computer text presentations more readable as a way of compensating for the constraints that computers impose on the display of text as compared with print-on-paper displays, e.g., limited screen resolution and display area. Forty-eight undergraduate teacher education majors enrolled in…
