This survey elicited experts' perceptions of factors affecting development and use of interactive technologies. Responses from 196 respondents were categorized as hardware/technology, software/programs, acceptance/adoption, accessibility/ease of use, and instruction/learning/communication issues. Based on this categorization, a model of…

Discussion of learner preferences for text densities on computer screen displays highlights two studies of college students that compared preferences for multiple or single screen presentations with high-, medium-, or low-density screens from an actual course using computer-assisted instruction. Results are analyzed, and further research needs are…

Proposes a schematic multidisciplinary model to help developers of intelligent computer-assisted instruction (ICAI) identify the types of required expertise and integrate them into a system. Highlights include domain types and expertise; knowledge acquisition; task analysis; knowledge representation; student modeling; diagnosis of learning needs;…

Discussion of computer-mediated communication (CMC) focuses on an international electronic Delphi study that was conducted to predict the prevalent instructional CMC applications that will be used in colleges and universities in the near future. Resources required for support and obstacles to be overcome are discussed. (Contains 81 references.)…

Describes study of undergraduates that examined uses and effects of learner control of the context or theme of practice examples on a computer-based statistics lesson in combination with the number of examples examined. Student attitudes are discussed, and correlations between learner characteristics and task outcomes are examined. (38 references)…

Describes a study of undergraduates that compared three strategies for indicating links in a hypermedia system to determine their effect on learner navigation and learner perceptions of ease of use. Highlights include three linking display types; the density of links; elaboration types; time intervals; and implications for hypermedia system…

Describes a study that examined the effectiveness of 1 configuration of automatic speech recognition software and hardware with 36 3 year olds and a comparison control group of 20 adults. The greater variability of children's speech is discussed; possible system modifications are considered; and future research is suggested. (18 references) (LRW)

Discusses the evaluation of instructional software, describes two versions of a software evaluation model, and reports the results of two studies that compared evaluative decisions based upon subjective software ratings and data collected using both versions of the evaluation model. Teacher use of student data for decision making is also examined.…

Describes a study that investigated the interaction of learning-disabled students and their teachers with instructional elements of commercial courseware. The relationship of courseware design to student independence and motivation is discussed, implications for improving courseware design are noted, and ideas for further research are suggested.…

Describes a new model for evaluating instructional software that focuses on the extent to which students learn the skills a software package is intended to teach. Results of a field test of fifth grade students are reported, and implications of the initial evaluation of the model are discussed. (14 references) (LRW)

Describes a study that investigated the effects of learner control and of advisement in a hypertext learning environment with second-grade students who had different levels of prior knowledge about the content. Topics discussed include computer-assisted instruction; learner control; and recommendations for instructional design in a hypertext…

Discussion of teachers' knowledge of instructional design principles highlights a required computer literacy course for preservice teachers that was redesigned to include substantial components to teach instructional design. Results of a study that was conducted to examine the effectiveness of the instructional design training are described. (18…

Describes a study of families with microcomputers that was conducted to determine the extent to which children used their home microcomputers for learning school subjects. Content analysis of log material is discussed, three specific case studies are presented, and reasons for the absence of home academic microcomputing by children are suggested.…

The effects of variations in learner control were examined for an interactive lesson presented as a videodisc visit to an art museum. The 101 first and second grade subjects were assigned to program control, learner control, and learner control with advisement conditions, or to a control group. Data on achievement and curiosity were analyzed. (28…

Describes two studies that compared university students' judgments about the readability and studyability of two sets of computer screens: a set of model displays and a set of real screens copied from computer-assisted instruction programs. Relationships among viewers' preferences and field dependence/independence, conceptual style, and gender…
