Previous research has indicated the disconnect between example-based research focusing on worked examples (WEs) and that focusing on modeling examples. The purpose of this study was to examine and compare the effect of four different types of examples from the two separate lines of research, including standard WEs, erroneous WEs, expert (masterly)…

To foster medical students' diagnostic knowledge a case-based worked example approach was implemented in the context of a computer-based learning environment. Thirty medical students were randomly assigned to the condition "with erroneous examples", and 31 students learned with correct examples. Diagnostic knowledge was operationalised…

This study investigates the hypothesis that students' learning and problem-solving performance in ill-structured domains can be improved, if elaborative question prompts are used to activate students' context-generating cognitive processes, during case study. Two groups of students used a web-based learning environment to criss-cross and study…

Describes an experimental test conducted with high school students to determine the effect of posting explicit goal structures on problem-solving performance in an intelligent tutoring system for calculus. Related rates word problems are discussed, and student performance in terms of speed and accuracy is analyzed. (Contains 29 references.) (LRW)

These reflections by the authors of a paper (EC 611 427) on computer-assisted instruction of students with learning disabilities comment on their reanalysis of the research process and their interpretations of the unanticipated results. Implications for further research on the cost effectiveness of learning-strategy training versus time-on-task…

Describes a study of graduate students that investigated whether a lengthened HyperCard stack treatment could promote problem-solving ability and reduce computer anxiety. The study was based on previous research that compared BASIC programming with HyperCard. Highlights include authoring languages and the effect of different instructional formats…

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…

The aim of the present study was to investigate those factors influencing performance in solving story problems in a web-based environment. A situational simulation, "Hiking across Estonia," was explored by two samples of voluntary groups of students, comprising 65 and 50 groups, respectively. They solved 25 ecological and environmental story…

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.…

Discussion of computer literacy, database technology, and higher-order thinking skills focuses on a study that compared the problem-solving performance of fourth-grade students receiving search strategy training during computer-assisted instruction with students who did not receive training. Time spent on problems and the number of correct answers…

Describes a study that provided innercity fourth grade African-American students in Texas with hardware to participate in a telecommunications network to determine whether participation would increase their scores on statewide fifth grade math tests. Time online, content of programs, connections between math and language arts, and student…
