This study examines the effect of an entering behavior, i.e., the level of general knowledge of the subject matter, on the instructional effectiveness of illustrations which integrate abstract and realistic visualization. Subjects were 414 public school students who were divided into three groups according to their general level of knowledge of…

Two variables that designers should consider when developing computer-based instruction (CBI) text screens are text density, which manipulates the context of the information presented, and screen density, which is a measurement of the amount of information presented at one time on the screen. A study on text density was designed to identify…

This paper presents a global approach to the media comparison literature. Beginning with the pros and cons of media research, it discusses the results of both individual and meta-analysis research, compares the different methods researchers have used to determine media selection, and concludes with the most recent trends in media selection. It is…

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.…

Addresses the implicit assumption that instructional media represent meaningful experimental variables independent of instructional content or strategy. Results of computer-based instruction (CBI) studies (both well-designed and flawed) and meta-analyses are reviewed to support the authors' position that this assumption is invalid, and new…

This study explores a relatively new area of computer research, i.e., utilization of computer-generated feedback based upon the knowledge gained in both written and computer-based instruction. One hundred and twenty-six freshmen and sophomore college students from a variety of academic majors volunteered for this study. The instructional materials…

The influence on learning of visuals accompanying self-paced text materials was investigated for students of varied reading comprehension ability levels. The use of varied degrees of realism and media presentation formats in facilitating learning on specific tasks was examined in order to clarify previous research, and to provide specific…

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…

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…

A critical process in developing lessons for computer-based instruction (CBI) is to determine the manner in which information will be displayed on the screen, taking care not to ignore the computer's special display capabilities. The underlying assumption of this study was that reducing the density of text presentation would be effective for…

This field study examined learning effects attributable to instructional design characteristics when eighth-grade science students used a print encyclopedia or a videotex version of the encyclopedia to write term papers. Results suggest that specific effects of instructional design characteristics of a delivery system are of a limited nature. (MBR)

Current issues in educational communications and technology are addressed in this collection of 31 papers, in which research reports predominate. Topics discussed include factors related to the learner, e.g., aptitude, recall, computer anxiety, field dependence/independence, reading ability, learning strategies, and cognitive style. Presentation…

A computer software package has been developed to teach and test students on the Rules for Alphabetical Filing of the Association of Records Managers and Administrators (ARMA). The following computer assisted instruction principles were used in developing the program: gaining attention, stating objectives, providing direction, reviewing…

Current issues in educational communications and technology are addressed in this collection of 47 papers, in which research reports dominate. Topics discussed include factors related to the learner, e.g., problem-solving skills, motivation, comparison of instructional design strategies, effects of organizational cues and text layouts, and…
