This study attempted to determine the influence of prior knowledge in mathematics of students on learner-interface interactions in a learning-by-teaching intelligent tutoring system. One hundred thirty-nine high school students answered a pretest (i.e., the prior knowledge in mathematics) and a posttest. In between the pretest and posttest, they…

The superiority of learner-paced over system-paced instructions was demonstrated in multiple experiments. In these experiments, the system-paced presentations were highly speeded, causing cognitive overload, while the learner-paced instructions allowed adjustments of the presentational flow to the learner's needs by pacing facilities, mostly…

In the past decade, a number of adaptive hypermedia learning systems have been developed. However, most of these systems tailor presentation content and navigational support solely according to students' prior knowledge. On the other hand, previous research suggested that cognitive styles significantly affect student learning because they refer to…

This study examined the role of learners' perceptions in a learner-controlled computer-based learning environment. Computer-based learning environments that offer learner control (LC) to the learners are assumed to enhance motivation and learning outcomes. Recently, the focus of LC research has shifted from measuring the direct effect of LC on…

Focusing on the composing process, this series of articles discusses improving composing by exploring personal experience and the use of computers and specific computer composition programs for teaching writing. (HTH)

This study investigated patterns and effects of cognitive tools usage during engagement with an open-ended hypermedia learning environment. Seven technical institute students engaged in problem-solving tasks concerning anatomy and physiology. They used 16 cognitive tools embedded in a hypermedia system and their tool use patterns and corresponding…

This study assessed the effects of varying degrees of elaboration in a prose format using computer-assisted instruction (CAI) with accompanying slides on posttest scores of college age learners. Four instructional treatments were used: control, embedded questions (TR1), computer generated feedback (TR2), and computer generated feedback with a…

Describes a study of undergraduates that was conducted to determine students' preferences toward Graphical User Interface versus Command Line Interface during computer-assisted instruction. Previous experience, comfort level, performance scores, and student attitudes are examined and compared, and the computer use survey is appended. (Contains 13…

Describes a study of college students that was conducted to examine the effectiveness of integrating different computerized visual-presentation strategies in learning different contents; the effect of identical presentation strategies on students possessing different levels of prior knowledge; and whether the use of different visual strategies…

A method to facilitate collaborative learning in complex learning environments was developed and evaluated. Sixteen college students of educational science were given the CoStructure-Tool, a task-specific computer-based tool developed on the basis of concept mapping techniques to support the processes of knowledge construction in collaborative…

Describes study that was conducted at the University of Massachusetts at Amherst to examine variables that determine which undergraduates use microcomputers and how often they use them. Computer access, expected future computer use, and prior computer experience are discussed, and the influences of gender and class rank are examined. (17…

Describes study that was conducted at Bar-Ilan University (Israel) to examine the influence of previous experience on the computer activity of first-year university students. The average computer activity for high-experience and low-experience groups is analyzed, and implications for beginning computer courses are discussed. (10 references) (LRW)

Many topics in chemistry are difficult for learners to understand, including symmetry. Reasons for this difficulty include its multi-level content, instructional methodologies utilized, and learner variables. This study examined the effect of initial instructional modality and prior knowledge on learning of point group symmetry. Forty-four…

Computer-based instruction opens new avenues for increasing the variety of possible feedback strategies that a teacher may employ to optimize learner performance. Feedback effectiveness is influenced by the nature of learning task and student ability. This study investigates the effects of digitized feedback and ability on the achievement of…

Investigated the effects of units using computers and computer-administered tests. The greatest benefit was attained by those using the units and attending lectures. Students using both the units and tests did not perform as well as the lecture only group. Explores the correlation between high school grades and the methods. (Author/YP)
