Describes a study of college freshmen that investigated the effects of navigation maps on search performance, browsing behavior, and cognitive map development within hierarchical-structured hypertext courseware. Results of analysis of variance indicate that map type significantly affected search performance and browsing behavior. (Author/LRW)

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)

Describes a study of high school students that investigated the impact of embedding an instructional map into hypermedia courseware on student achievement. Treatment of experimental and control groups is described, results of pretests and posttests are compared, and implications for software designers and teachers are suggested. (Contains 23…

This exploratory investigation examined relations between teachers' views of knowledge acquisition and their use of computers in the classroom. A survey instrument that assessed views ranging from objectivism to constructivism is described; and teaching experience, demographic variables, and types of software programs likely to be used are…

Describes study that examined the relationship between computer anxiety and the use of psychology courseware in an undergraduate abnormal psychology class using four computerized case simulations. Comparisons of pretest and posttest computer anxiety measures are described, and the relationship between computer anxiety/attitudes and computer use is…

Describes study that was conducted to determine whether four- and five-year-old preschoolers could be taught reading skills with computer-assisted instruction, and whether they could learn basic computer literacy skills without direct instruction and drill. Software is described, and the pretest/posttest single group design is explained. (16…

Describes a survey of physics and physical science teachers in Iowa that was conducted to determine their use of microcomputers. Availability of computers and types of software used are examined, frequency of use and access to computer laboratories are investigated, and results are compared with those from earlier surveys. (seven references) (LRW)

Describes a study that investigated the feasibility of using computers to teach music notation systems to Chinese students, as well as to help Western educators study Chinese music and its number notation system. Topics discussed include students' learning sequences; HyperCard software; hypermedia and graphic hypertext indexing; and the…

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…

Describes study of fourth and fifth grade students which explained the effect of graphics on student motivation in a microcomputer-based spelling drill program. The role of feedback in instruction is discussed, the impact of graphics on computer software is described, and results are analyzed. (4 references) (LRW)

The DAPPOR software, a drill and practice program for learning the command languages of major vendors of bibliographic databases, was tested in a classroom environment at two library schools. Statistically significant positive learning differences were observed with DAPPOR use, particularly with the DIALOG language. (21 references) (Author/EJS)

Discussion of menu design strategies for computer-assisted instruction (CAI) focuses on a study that investigated whether menu design would affect undergraduate learners' usage patterns during a CAI lesson. Sequential versus random selection of options is discussed, and new measures for describing usage patterns in CAI are explained. (eight…

The effects of microcomputer use on preschoolers' knowledge of pre-reading concepts and attitudes toward microcomputers were investigated. Seventy-seven preschoolers were randomly assigned to three treatment conditions: (1) adult-assisted microcomputer instruction; (2) unassisted microcomputer use; and (3) no computer use. Analysis of pretest…

Describes study that was designed to examine the impact of action and sound on preschool children's preferential selection and recall of verbal content presented in a computer microworld. Visual superiority and auditory superiority hypotheses are discussed, sex differences are examined, and results indicate the importance of including action. (29…
