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)

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)

Discussion of hypertext systems and navigation focuses on a study conducted with undergraduates at Clemson University (South Carolina) that compared a hypertext browsing system with a linearly based system for accessing information concerning college transfer courses. Results indicate that user perceptions and performance are more favorable with…

Three conditions of self-monitoring of private study were compared for their effects on academic performance and intrinsic motivation. In end-of-year examinations, a group who self-monitored subgoals outperformed groups who self-monitored either time or study or distal goals on the target course of the investigation. (Author/LMO)

Describes a study of college students that examined the instructional effect of visual and verbal metaphors in facilitating student achievement of different educational objectives. The effect of students' verbal ability and the amount of time they spent interacting with their respective instructional modules were also measured. (Author/LRW)

Describes a study of college students that investigated whether various types of visual illustrations influenced abstract concept learning when combined with audio instruction. Discusses results of analysis of variance and pretest posttest scores in relation to learning performance, attitudes toward the computer-based program, and differences in…

A study of undergraduate students investigated whether different rehearsal strategies are more effective in facilitating achievement, whether certain rehearsal strategies require learners to spend more time interacting with instructional content, and whether verbal or visual testing requires students to spend more time processing and responding to…

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)

This study examined the instructional effect of varied graphic mapping strategies (spider maps, frame maps, and semantic maps) in facilitating college-student achievement of different types of educational objectives, and the significance of the amount of time students have to process the information presented in the varied mapping strategies.…

This study examined effects of orienting activities, processing opportunity, and varied lesson access times on college students' learning from interactive video. While practice remains dominant influence in effectiveness of interactive video, significant interactions were also found among access times, processing opportunity, and practice, and…

Discusses integrated learning systems (ILSs) and describes a study that considered the degree of linear relationship between time spent on the ILS and outcome achievement on ninth-grade algebra students. The effects of previous math and verbal achievement and sex differences are explored, and measurement instruments are described. (Contains 14…

Discussion of various types of feedback used in computer-assisted instruction focuses on a study of low-ability eleventh graders that compared the effectiveness of answer until correct (AUC) feedback with knowledge of correct response (KCR) feedback. Achievement data on posttests as well as time data are analyzed. (11 references) (LRW)

Describes a study that investigated the effects of learner control and program control, and lean and full modes of instructional programs, on the achievement, use of options, time on task, and attitudes of high-ability and low-ability students from grades 9 and 10 during computer-assisted instruction. (LRW)

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…
