Describes a study of undergraduates that was conducted to examine the equivalence of the mode of administration using the paper-pencil and computer-based versions of the Strong-Campbell Interest Inventory. Differences in scores are discussed, time taken for the inventories is studied, and further research is suggested. (Contains 16 references.)…

This study measures performance frequency of leadership tasks of approximately 20 percent of Colorado's principals. Principals most experienced do not differ from others on the frequency assessment scale, yet spend more time on instructional leadership activities, which range from teacher support (professional growth opportunities, rewards) and…

Discussion of how we perceive meaning from graphics highlights a computer simulation model, UCIE (Understanding Cognitive Information Engineering), that simulates graphical perception. An empirical study is described that compared actual performance to UCIE predictions related to the amount of time required to answer a question in various…

Describes a study of undergraduates that compared the effects of response-certitude adaptive and nonadaptive feedback in a computer-based lesson of verbal information and defined concept tasks. Effects on student performance, feedback-study time, and lesson efficiency are discussed, and implications for future research are suggested. (LRW)

This study examined the effectiveness of a computer algebra system in teaching secondary school mathematics. Pre- and posttest results and time on task were compared for students receiving conventional instruction and those receiving computer-assisted instruction using an enhanced version of muMath, a standard computer algebra package. (four…

Presents a meta analysis which examines results of 254 controlled evaluation studies that compared student learning in classes taught with and without computer-based instruction (CBI). Outcome measures are described, statistical analysis and effect size are discussed, and results are reported that show that CBI usually produces positive effects on…

Describes a study conducted at the University of Iowa College of Dentistry that compared the effectiveness and efficiency of adaptive instruction with nonadaptive instruction using interactive videodisc patient simulations. The Dental Diagnosis and Treatment (DDx&Tx) System is explained, and problem-solving skills and study time are discussed.…

The amount of time students are exposed to material is one measure of student access to learning opportunities. This information sheet compares instructional time for students in several developed countries. However, how effectively classroom time is used had the greatest influence on student learning. The average amount of time 13-year-olds spent…

This meta-analysis of 49 comparative studies shows that mastery testing has positive effects on student learning, but the size of effect depends on the stringency of the criterion used and the degree of experimental control. The effects of instructional time, student attitudes, and differences in ability levels are also addressed. (Author/LRW)

Describes a study that compared individual computer-assisted instruction (CAI) with paired/cooperative CAI as a method of providing inservice training for cooperative extension agents on the topic of proper water well location and construction. Cognitive achievement and time spent on the lesson are investigated. (18 references) (LRW)

This study demonstrated that, although standard instructional design revisions of a traditional textbook chapter had no effect on teacher attitudes toward adoption of the material, the revised version of the chapter significantly improved student performance. Teacher and student participants in the study were from the St. Petersburg…

Discussion of learner-controlled instruction focuses on a study of undergraduates that compared learner control with program control in interactive videodisc instruction for making an origami crane. Student performance, self-efficacy concerning the instructional task, time on task, and student attitudes toward the instruction are examined. (32…

Reports on a study investigating the importance of audio and textual redundancy in a computer-based, multimedia training program with identical content that undergraduate students used under one of the following conditions: full-text and totally redundant audio delivery; partial-text with full audio delivery; or graphics only with full audio…

This study investigated the effects of audio and text density on the achievement, time-in-program, and attitudes of 134 undergraduates. Data concerning the subjects' preexisting computer skills and experience, as well as demographic information, were also collected. The instruction in visual design principles was delivered by computer and included…

Describes a study that compared the effects of cooperative and individual learning on fifth and sixth grade student performance and attitudes during interactive videodisc instruction for science. The use of heterogeneous ability groups is discussed, time on task is examined, and further research is suggested. (22 references) (LRW)
