Investigated effects of computer assisted instruction (CAI) on learning efficiency, defined as either higher passing percentage or less time on task. Subjects (N=24) were college mathematics students who either were lectured or had a CAI tutorial on the lowest common denominator. The CAI group took less time, but solved more problems incorrectly.…

Comparison of basic reading instruction by either computer assisted instruction or traditional book methods with eight children (ages 3-5) with autism found all children spent more time on task in the computer condition and that five of the eight children could reliably identify at least three words after the computer assisted learning. (Contains…

This study investigated the impact of prior knowledge, writing task, and hypertext format on university students' comprehension of multisource hypertext. Fifty-two students categorized as having high or low prior knowledge studied hypertext consisting of seven component texts on the topic of social influence. Some students were given a summary…

This paper attempts to identify and address the assumptions that have been made about the engagement of learners in online learning environments. Research studies have shown that learner engagement is paramount to learning success (Herrington, Oliver, & Reeves, 2003). Defined here as the "the mobilization of cognitive, affective and motivational…

This exploratory study investigated the influence of two recreational computer games on children's subsequent performance on computer-based instructional tasks. Examined speed, correct solutions, and cognitive processes; and suggests that the extent of recreational game influence depends on how closely the game type matches the design of the tasks…

Discusses computer access in schools; explains how to determine sufficient quantities of computers; and describes a formula that illustrates the relationship between student access hours, the number of computers in a school, and the number of instructional hours in a typical school week.

This study investigated whether achievement, completion rate, and lesson time vary with computer-screen layouts using good design principles compared with poorly designed screens. Results with adult learners using computer-based instruction showed no difference in achievement scores but good design did lead to higher completion rates and less time…

This study investigated the role that computer technology plays in transforming the learning process in higher education. Specifically, we looked at the relationship between computer-technology use, active learning, and perceived course effectiveness. The sample consisted of 1966 students in 81 graduate and undergraduate classes at a large, urban…

Describes the design and application of the Resource Questionnaire, an instrument developed at the University of Glasgow (Scotland) to gather information on the learning resources used by students, particularly computer-assisted learning. Topics include amount of time to use resources; usefulness of resources; ease of access; and preliminary…

Discussion of the design of computer menus focuses on two experiments that examined task time across several orderings of menu lists. Findings are described that demonstrated that good physical layout in screen design is not sufficient without good conceptual layout. The size of menu lists for maximizing efficiency is considered. (Contains 17…

The evidence, regarding the influence of study time on students' perception and use of learning activities in open and distance teaching materials--a major contributor to the quality of student learning--is briefly reviewed. In addressing the problem of student workload, three key questions are considered: How much time do your students have for…

Describes performance criteria for users of computer assisted instruction (CAI) that are used to provide users with feedback about their performance relative to other users. This study evaluated 146 novice users on their percentages of correct responses, time required for completion, and number of times the CAI tutorial was performed. (LRW)

Investigated the effects and efficiency of mandatory and optional note taking by undergraduate students (n=81) during computer-based instruction. The required note takers entered notes on every screen of the HyperCard lesson; this group scored significantly higher on the post-test and took significantly longer to complete the instruction than did…

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)

We investigate the dynamics of student engagement as it is manifest in self-directed, self-motivated, relatively long-term, computer-based scientific image processing activities. The raw data for the study are video records of 19 students, grades 7 to 11, who participated in intensive 6-week, extension summer courses. From this raw data we select…
