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 effect of instructional analogy training on the level of immediate, as well as 14-day delay, comprehension of tangible and intangible physiological concepts was investigated. Ninety-four college-aged subjects were given training either with or without instructional analogies over five tangible and five intangible advanced physiological…

This study was designed to determine whether systematically designed text augmented with compressed speech could increase the number of objectives achieved and reduce the amount of learning time needed for mastery of the objectives. Subjects were 78 students from 5 Florida schools with vocational education programs. Their reading levels ranged…

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…

This study considered the effects on lesson completion time of four forms of immediate feedback. Thirty-two low-ability eleventh grade students were randomly assigned to one of four treatments. Each student received four one-page social studies reading passages. Each passage averaged 350 words in length. Eight 4-alternative multiple choice…

Although both learner control and feedback have been heavily researched, very little research has been conducted on giving learners control over the feedback which they receive. The purpose of this study was to examine the effect of learner control of feedback in a computer assisted instruction (CAI) lesson. The independent variables were type of…

This research project was designed to explore ways of making computer text presentations more readable as a way of compensating for the constraints that computers impose on the display of text as compared with print-on-paper displays, e.g., limited screen resolution and display area. Forty-eight undergraduate teacher education majors enrolled in…

The Memphis Apple Classroom of Tomorrow (ACOT), one of seven ACOT locations, was a joint project of the city schools and Apple Computer. The ACOT consisted of a class of 30 fifth grade students in an inner city school, who were selected on the basis of the willingness of the students and their parents to participate and to use computers in the…

The primary purpose of this study was to examine the effects of replacing multiple-choice questions in tutorial software practice interactions with a learning strategy (i.e., learner-generated summaries) on immediate recall. Subjects were 35 students--32 females and 3 males--from an undergraduate computer course in the College of Education at…

The purpose of this study was to investigate the effects of learning strategy and summarization within a computer-based chemistry and physics program. High school students worked individually or in cooperative dyads to complete science instruction; half of them completed summaries over the instructional content when directed to do so. The study…

This study investigated the effects of audio and text density on the achievement, time-in-program, and attitudes of 134 undergraduates. Data concerning the subjects' preexisting computer skills and experience, as well as demographic information, were also collected. The instruction in visual design principles was delivered by computer and included…

Designed to develop a more practical model for adapting context to learner interests, this study used computer-based instruction to make alternative contexts for statistics problems--sports, business, education, or no-context--available for selection by individual learners. The subjects were 227 undergraduate students enrolled in required…

Using the cognitive fit paradigm as a theoretical framework, this study compared the problem-solving performance of users of a hypertext-based learning aid to the performance of users of a computer-based linear text learning aid. Subjects were 103 undergraduate MIS (Management Information Systems) majors enrolled in an information systems analysis…
