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…

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…

In machine-mediated learning environments, there is a need for more reliable methods of calculating the probability that a learner's response will be correct in future trials. A combination of domain-independent response-state measures of cognition along with two instructional variables for maximum predictive ability are demonstrated. (Author/LRW)

Describes a study of undergraduates that compared the effects of response-certitude adaptive and nonadaptive feedback in a computer-based lesson of verbal information and defined concept tasks. Effects on student performance, feedback-study time, and lesson efficiency are discussed, and implications for future research are suggested. (LRW)

Variables and conditions that influence the learning of computer-presented expository text were investigated in this study, in which on-screen underlining was used as a learning aid to increase "mindful" processing of information. The effects of three intervening variables--amount of invested mental effort (AIME), learning style, and…

Discusses the application of spelling research findings to the design of computerized instructional spelling programs. The need for individualization is stressed; lesson size, content, and time devoted to instruction discussed; three cognitive models with appropriate instructional strategies for each are presented; and further research needs are…

Describes a study of 80 undergraduate foreign language learners that compared the use of a hyper-reference source incorporating an electronic dictionary and a conventional paper dictionary. Measures of consultation frequency, study time, efficiency, and comprehension are examined; bilingual and monolingual dictionary use is compared; and further…

Describes study of undergraduates that compared the effects of different small group sizes on learner achievement using computer controlled interactive videodisc. The results of pretests and posttests are reported, learning achievement and instructional time are used to calculate an instructional efficiency index, and further research is…

Describes a study of Korean elementary school students that was conducted to investigate the effects of differing types of instructional control strategies and cognitive style on achievement in arithmetic skills using computer-assisted instruction. Hypotheses tested are discussed, time on task is investigated, and future research is suggested.…

Explains the combination of hypertext and knowledge maps into hypermaps, and describes a study of undergraduates learning statistical material that compared the effectiveness of using hypertext versus hypermaps. Recall, reference time and accuracy, and student satisfaction are investigated, and needs for further studies are suggested. (10…

Describes a study that compared the effectiveness of computer-mediated communication systems for teacher education distance education courses with traditional classroom instruction and a correspondence course at Purdue University. Variables examined are described, including achievement test scores, time-on-task, and students' attitudes; and…

Describes a study of undergraduates that investigated the use of hypermedia programs by learners classified as active, passive, or neutral. Two instructional approaches were compared, one utilizing instructional cues and one without instructional cues; and dependent variables including achievement, time on task, and frequency of viewing embedded…

Describes a study that compared animated demonstrations, procedural textual instructions, and demonstrations combined with spoken procedural text to assess the effectiveness of animated demonstrations for users learning HyperCard. Results of accuracy, time on task, user responses, retention, and transfer are discussed; and future research is…

Describes a study that was designed to investigate the interaction between three levels of instructional control (i.e., linear, mixed, and learner) and provision of an orienting activity on college students' learning of factual and procedural knowledge via interactive video. Instructional time and recall of facts and procedures are examined. (35…

Describes a study that investigated the effect of curiosity on learning art education facts and concepts by first and second graders in computer-based interactive learner-controlled environments with and without advisement. Results are compared with a previous study on learner control and advisement, and implications for instructional design are…
