Describes a study of second, third, and fourth grade children in Israel to determine if computer assisted instruction is utilized differently by different groups of students (younger and older), and extent to which effort expenditure (total amount of time a child is engaged at the computer) is related to achievement. (MBR)

Reports research on computer assisted instruction (CAI) which has attempted to understand why CAI often accomplishes learning goals in less time and describes the "Beginning Teacher Evaluation Study" which investigated the way students use their time, actual time-on-task, and quality of student involvement with subject content. (EAO)

Investigates the effect of implementing cooperative versus individual learning and orienting activities during computer-based instruction (CBI). Results indicated that students who received instructional objectives performed significantly better on posttests than students who received either advance organizers or no orienting activities. Learning…

Forty-seven 10th graders were observed for seven weeks to investigate effects of computer-assisted drill-and-practice instruction (CAI) on student achievement and their off-task behavior compared with similar seatwork in a business education class. Results indicated higher achievement and higher rates of on-task behavior during the CAI condition.…

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…

This document reports an experiment designed to assess the effects of learner control over the level of challenge in computer-assisted instruction (CAI) and collect data that will guide the design of future learner control experiments. The subjects were 78 undergraduate students in the College of Education at a large public university. The CAI…

The exploratory study examined computer use during free time in two classrooms for mildly and moderately retarded 3- to 5-year-olds. Results indicated that computer use was a popular activity choice, that children used the computer for a relatively long time, that they preferred software with excellent graphics, and that they rarely chose…

Six life skills students with varied mental disabilities at Eastern High School in a Pennsylvania school district received mathematics instruction through the use of a PLATO computer-assisted instruction program for mathematics. The purpose of this evaluation was to determine whether the use of computer-assisted instruction increased the students'…

Demonstrates how Bayesian reasoning can be used to adjust the length of computer-guided practice exercises and computer-based tests to help make mastery or nonmastery decisions. Individualization of instruction is discussed, and the results of an empirical study that used the sequential probability ratio test (SPRT) are presented. (25 references)…

Describes a study of undergraduates that compared three strategies for indicating links in a hypermedia system to determine their effect on learner navigation and learner perceptions of ease of use. Highlights include three linking display types; the density of links; elaboration types; time intervals; and implications for hypermedia system…

Examines the effect of using "Learning Expedition", an integrated learning system based on computer-assisted learning, on the performance of mathematics students ages 11 to 13. Results of multiple-regression methods, used to estimate the statistical relationship between examination scores and time spent using "Learning Expedition," show a…

Examines the effects of type of instructional control (learner control versus program control) and program mode (full versus lean) on the achievement, option use, time in the program, and attitudes of higher-ability and lower-ability university students using a computer-delivered instructional program. Discusses implications for instructional…

This study presents time-and-task records of faculty and teaching assistants' time for comparable computer-aided design courses at two state universities in the midwestern United States. One course was taught at a distance and the other course was a conventional face-to-face course. Results indicate a distance course takes less time to teach than…

This research is an effort to best utilize the interactive anatomical images for instructional purposes based on cognitive load theory. Three studies explored the differential effects of three computer-based instructional strategies that use anatomical cross-sections to enhance the interpretation of radiological images. These strategies include:…

Studies comparing computer-assisted instruction with traditional print were reviewed in order to determine what researchers have discovered about using computers in reading. The research findings were then compared and integrated through using the following five categories: interaction, attitude, instructional control, time on task, and…
