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…

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.…

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…

This study examined learner-control strategies for selecting problem context and level of instructional support on a computer-based mathematics unit on the metric system. Subjects were 240 sixth grade students assigned to 15 treatments. Performance was lowest under learner-control instructional support conditions even though subjects indicated…

Describes a study of 80 undergraduate foreign language learners that compared the use of a hyper-reference source incorporating an electronic dictionary and a conventional paper dictionary. Measures of consultation frequency, study time, efficiency, and comprehension are examined; bilingual and monolingual dictionary use is compared; and further…

Describes a study that examined the effects of cooperative versus individual computer-based instruction on the performance of high- and average-ability fourth-grade students. Effects of learner and program control are investigated; student attitudes toward instructional content, learning in groups, and partners are discussed; and further research…

Describes a study that investigated the effect of curiosity on learning art education facts and concepts by first and second graders in computer-based interactive learner-controlled environments with and without advisement. Results are compared with a previous study on learner control and advisement, and implications for instructional design are…
