This study manipulated the timing and control of error feedback in problem solving and examined their effects on skill acquisition by 40 undergraduate students learning to program in the computer language Lisp under four error feedback conditions. These four conditions included two types of symbol-by-symbol feedback that vary in content, a…

A study examined the effects of different teacher styles on one variable related to classroom learning production. Subjects, 34 first grade middle- and lower-middle income students in a Catholic school matched by ability and randomly assigned to either an authoritarian, systematic, ordered, and controlling teacher or to a "laissez faire"…

High and low level questions as determined by a panel of evaluators were combined with corrective feedback and attribute isolation feedback to form four versions of a computer-based science lesson. The sample consisted of 154 high school chemistry students in a suburban high school. The primary hypothesis was that students who received high level…

In machine-mediated learning environments, there is a need for more reliable methods of calculating the probability that a learner's response will be correct in future trials. A combination of domain-independent response-state measures of cognition along with two instructional variables for maximum predictive ability are demonstrated. (Author/LRW)

Describes a study of college students that investigated whether various types of visual illustrations influenced abstract concept learning when combined with audio instruction. Discusses results of analysis of variance and pretest posttest scores in relation to learning performance, attitudes toward the computer-based program, and differences in…

Describes a typology of the use of educational media that includes audience, location, time, interactivity, cost, and training. Compares a variety of educational media including radio, television, CD-ROM, and Internet-based instruction, and concludes that Internet-based instruction has the most potential. (Contains 12 references.) (LRW)

Describes a study of university students that investigated the effects of a variable unique to Internet-based learning, namely download delay of instructional materials. Discusses a simulated online teaching tool that measured the effects of download delay of images on test performance, time spent on the material, end-user satisfaction, and…

Pharmacology is taught on a dedicated module for nurse prescribers who have a limited physical science background. To facilitate learning a problem-based approach was adopted. However, to enhance students' knowledge of drug action a PharmaCALogy software package from the British Pharmacological Society was used. Students were alternately given a…

A computer-assisted instruction (CAI) program using Utah PILOT programming language was constructed that includes the same objectives that are taught during the presentation of a traditional library tour. The amount of time necessary to complete the CAI program is approximately the same time needed by a student taking a library tour. The…

This study focused on the transition in memory between conceptual knowledge formation and procedural knowledge development. The first variable--display time interval--controlled the amount of instructional display time of each interrogatory example; the second variable--content sequence--sequenced examples according to response-sensitive decision…

Compares achievement effects and time-on-task generated for computer and non-computer versions of essentially the same game. Notes that students followed different rules for the same game and pace was faster for computer versions. Reports transfer of instruction may not be complete. (MVL)

Reviews current research regarding integrated learning systems (ILS) in elementary and secondary education. Topics discussed include instructional effectiveness; implementation strategies, including adequate time, teacher involvement, curriculum integration, and staff development; classroom social processes; and implications for teachers. (LRW)

Examines factors that affect the successful implementation of integrated learning systems (ILSs). Empirical studies of ILSs are discussed; implementation models are considered; and factors that facilitate or hinder implementation are described, including student time on the system, teacher involvement, integration with the classroom curriculum,…

Discusses the change in teachers' roles with integrated learning systems (ILSs) from the role of deliverer of instruction to manager of instruction. Topics addressed include scheduling; assigning lessons; motivating students; evaluation of task performance; the communication process; time equity; merging the ILS with the classroom curriculum; and…

Discussion of hypertext structures focuses on three studies of preservice teachers that assessed the effects of different methods of explicitly mapping expert knowledge structures onto hypertext on the acquisition of structural knowledge. Topics addressed include time on task, semantic networking, cognitive limitations of browsing behavior, and…
