Previous study has shown that tracing gesture may enhance the worked example-based learning by reducing cognitive load. The present study attempted to replicate the previous results and further explored the individual differences in tracing effect in relation to the learners' working-memory capacity. Specifically, 11- to 13-year-old students…

The current studies investigated the efficient use of dialogue in intelligent tutoring systems that use natural language interaction. Such dialogues can be relatively time-consuming. This work addresses the question of how much dialogue is needed to produce significant learning gains. In Experiment 1, a full dialogue condition and a read-only…

A large body of research has shown that for novice learners, instruction that relies more heavily on worked examples than on problem solving, is more effective for learning as shown by higher test performance. Moreover, this beneficial effect is often obtained with less acquisition time and lower cognitive load during acquisition and test phase.…

A randomized posttest-only control group experimental design was used to determine the effects of think-aloud pair problem solving (TAPPS) on the troubleshooting performance of 34 secondary-level career and technical education students. There was no significant difference in success rate between TAPPS students and students who worked alone…

This study evaluated the effects of color highlighting during a math computation task on performance accuracy and behavior of students with attention problems. Using a multiple baseline across participants design, three students solved math computation problems on worksheets with and without highlighting. Off-task behavior recorded from videotape…

Using a single-subject alternating treatments reversal design, the effects of three conditions, tactile stimulation, auditory stimulation, and choice of the two, were compared on the math story problem solving of elementary students with attention problems. Students attempted and solved slightly more problems and engaged in fewer off-task…

This manuscript reports on a preliminary study to examine the effect of teaching problem-solving skills on the task persistence of handicapped preschool children. Ten mildly handicapped children completed a series of lessons in which they were taught to use problem-solving strategies to complete fine motor tasks. Both qualitative and quantitative…

Measures of learning appropriate to museums are explored, including the following: (1) time on task; (2) knowledge gain; (3) thinking and problem solving; (4) motivation; and (5) creativity or intellectual provocation. Museums promote different kinds of learning, but all are interested in knowledge gain and thinking. (SLD)

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…

Compared use of problems and the conventional case method as methods of instruction at the Utrecht University Law School (Netherlands). The problem method required students to find, frame, and analyze issues and provided training seminars in legal problem-solving skills. Students using problems spent more time on learning activities and performed…

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…

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.…
