Some studies of computer-assisted instruction have shown that when students control the amount of instruction they receive, they often terminate too early and fail to learn what they should. While sophisticated adaptive systems may eliminate the problem of premature termination of study, they neglect the important goal of learner responsibility. These researchers were interested in whether giving learners information about their achievement in relation to the criterion during instruction would improve learning in both learner-controlled and program-controlled systems. Success was measured in terms of posttest scores, time on task, and number of instructional examples required during instruction. 相似文献

Large scale computer-assisted instruction systems generally impose severe constraints upon the demands that individual users may make. Nevertheless, it is possible to overcome these problems and a program is described which teaches students how to fly a specific maneuver through real-time simulation of the flight of a student-controlled airplane. This is achieved in spite of the fact that the student is flying his plane through the use of a manually controlled analog input device. Both computational and educational implications are discussed.Contractual support for this work was provided in part by the Life Sciences Program Air Force Office of Scientific Research, Contract number F44620-70-C-0105.

Although considerable research has been conducted on both learner control and feedback, very little research has addressed
the effect of giving learners control over the feedback that they receive. The purpose of this study was to examine the effect
of learner control over feedback in a CAI lesson. Subjects used one of four CAI programs which provided either program control
or learner control over verification or elaboration feedback. Results indicated that subjects who received elaboration feedback
during instruction performed better than students who received verification feedback. Type of control did not have a significant
influence on performance. However, when subjects selected feedback for items answered incorrectly during instruction, subjects
under learner control/elaboration performed better on the posttest than subjects under learner control/verification. Implications
for the design of CAI are discussed. 相似文献

Summary The duration of the current experiment was admittedly quite short—30 minutes to an hour of learning time. A longer program
may have produced more pronounced differences. Sixty-four students including 32 high and low ability males and females were
randomly assigned to programed instruction and computer-assisted instruction programs on the topic of Significant Figures.
The results indicated that the students using programed instruction performed significantly better than those using CAI. This
difference was attributed primarily to the very poor performance by the low ability students in the CAI group. There was also
a significant ability effect. The posttest and retention test results, as well as number of errors in the actual learning
sequence, indicated there was a trait by treatment interaction which was interpreted primarily as a very poor performance
by low ability students on CAI, with almost equal performance by high and low ability students utilizing programed instruction.
The data would not support such explanations as the use of recognition responses or the inability to achieve any particular
concepts in the program for the performance of low ability students on the CRT-oriented CAI. Further research is suggested.

Three experiments were run using the SCHOLAR CAI system to teach geography to high-school students. The experiments compared a method of teaching derived from analysis of human tutors (Tutorial Mode) vs a method derived from programmed instruction (Block-Test Mode). In the three experiments, Block-Test Mode was systematically converged toward Tutorial Mode in order to pinpoint what aspects of teaching strategy affected student's learning. Tutorial Mode was significantly more effective in the first two experiments, and nonsignificantly in the third. The results indicated that the major factor affecting student's learning was the strategy that tutors use of reviewing the material in greater depth on a second pass. The advantage of CAI for purposes of implementing and evaluating different teaching strategies was discussed. 相似文献

Improving the quality and effectiveness of computer-mediated instruction through usability evaluations 总被引:1,自引:0,他引:1

Brigham Young University's Center for Instructional Design (CID) creates online courses and multimedia instructional applications for university faculty. This paper asserts that including usability testing as a part of evaluation improves the quality and effectiveness of computer‐mediated instruction. The paper describes the fundamental purpose and functions of usability testing, and also distinguishes between different forms of evaluation: accessibility, quality assurance (QA), usability and implementation. Through a detailed case study, we describe how usability testing improved the quality of a computer‐based chemistry course and facilitated a clearer analysis of the learning effectiveness of this course. 相似文献

The attributes of a commercial microcomputer software package were evaluated as a supplement to traditional instruction in general chemistry classes in a suburban public high school. During a unit of study of writing and naming formulas and balancing chemical equations, the experimental group received reinforcement via microcomputer while the control group used parallel worksheet exercises over a period of three weeks for concept reinforcement. Analysis of achievement scores indicated significantly higher scores among the students in the control group. In order to ascertain any possible differential effects favoring either method for students at varying cognitive development levels, the study investigated the relationship between treatment (CAI versus worksheet) and development stage; no significant interactions were discovered. 相似文献

Performance data were collected for students taking the computer-assisted instruction course in logic at Stanford University. The fit of the data to the Suppes, Zanotti, and Fletcher trajectory model was found to be good, though a systematic deviation from the model suggested some changes in the curriculum. A quantitative approach was used to pinpoint areas for curriculum revision. In addition, the model was evaluated for use as the basis of a predictive control mechanism.This research was supported by National Science Foundation Grant No. NSF-SED74-15016. The authors wish to thank Mario Zanotti for several discussions of the original model, and Lauri Kanerva for the use of his program for exponential regression analysis. 相似文献

The purpose of this study was to examine the effect of multimedia computer-assisted instruction (MCAI), traditional instruction
(TI), and combined instruction (CI) methods on learning the skill of shooting in basketball. Additionally, a comparison of
the students’ attitudes towards the MCAI and TI methods was made. Seventy-five middle school students of seventh and eighth
grade were randomly assigned into three teaching method groups: TI, MCAI and CI. Each group received ten 45-min periods of
instruction divided into three sections: (a) 5-min introduction, (b) 30-min instructional time and (c) 10-min questions and
review. Students took pre-, post-, and retention written test covering techniques and rules of the games. Participants in
the CI group also completed a post-test attitude survey towards the MCAI and TI methods. Two-way analysis of variances (ANOVA),
with repeated measures on the last factor, were conducted to determine effect of method groups (MCAI, TI, CI) and measures
(pre-test, post-test, re-test) on knowledge test. Paired samples t-test analyses were conducted to measure students’ attitude
towards the MCAI and TI methods. Post-test results indicated no significant differences between the groups concerning the
written test. Nevertheless, the attitude test scores of the CI group were more favourable to MCAI method than the TI method.
Retention test results showed that groups retained the knowledge acquisition. However, the combine method of instruction tended
to be the most effective on cognitive learning. 相似文献

In this study, the performance and attitudes toward instruction of learners working individually on a computer-based sex education lesson were compared with those of learners working cooperatively in dyads. A tatal of 60 eighth-graders received treatments that either required individual work or encouraged cooperation with a partner. Results indicated that students who worked cooperatively significantly outperformed those who worked individually. On an attitude measure, interactions were detected between instructional method and gender, as well as among instructional method, gender, and ability. High-ability males and females reported comparable attitudes toward each instructional method, but ratings for low-ability students were differentiated according to instructional method: Low-ability males responded most favorably, while low-ability females responded least favorably to individualized methods, and low-ability females responded most favorably and low-ability males least favorably to cooperative methods. 相似文献
