A self-paced programmed undergraduate course in the experimental analysis of behavior

An Empirical Evaluation of Student-Led Discussions

The discussion portion of the introductory psychology course at Western Michigan University was designed to develop creative, critical analysis of articles in terms of the attitudes of science. This program utilized discussion guidelines which became less and less structured and articles with violations of the attitudes of science which became more and more subtle. Different classroom procedures were utilized in an empirical analysis of the discussion methodology. Final examination scores did not reflect advantages of the discussion procedures, which were then eliminated from the course. An evaluation of the effectiveness of the text indicated that the same level of mastery could be achieved in 1 wk. as in the 7 wk. normally spent on this material. The study greatly reduced the number of student and staff man-hours and the over-all cost of the course.

Measuring and reducing college students' procrastination

We examined college students' procrastination when studying for weekly in-class quizzes. Two schedules of online practice quiz delivery were compared using a multiple baseline design. When online study material was made available noncontingently, students usually procrastinated. When access to additional study material was contingent on completing previous study material, studying was more evenly distributed. Overall, the mean gain in percentage correct scores on weekly in-class quizzes relative to pretests was greater during contingent access than during noncontingent access conditions.

A comparison of students studying-behavior produced by daily, weekly, and three-week testing schedules

Time spent in contact with academic course materials as a function of two testing schedules was measured using college undergraduates in an introductory educational psychology course. A within-subject (ABAB) design was employed with all subjects to allow for both individual and group analyses. A study room equipped with an adjacent observation room enabled visual and auditory monitoring of student study behavior. Academic materials were exclusively available to students in the study room and records of durations and distribution of student study time were made by an observer behind a one-way mirror. Daily testing produced consistent duration of study behavior with regular attendance at the study room; weekly and three-week testing produced sporadic bursts of study behavior and frequent instances of non-attendance. The amount of study behavior occurring in weekly and three-week testing conditions increased as the test time drew near (scalloping). Results suggest that daily testing supports more consistent study patterns than do the two larger intertest intervals investigated.

A note on some reinforcing properties of university lectures

Contingency management systems in university courses have sometimes assigned the role of reinforcing stimulus to lectures and demonstrations. Attending a lecture was made contingent upon having previously finished certain course assignments. The present paper investigated some variables that control student attendance at lectures. Attendance remained high throughout each course at those class meetings where quizzes contributing to course grades were given or where impending quizzes were discussed. Attendance at lectures over the reading assignments or over material unrelated to course quizzes rapidly declined. When students were given course credit for attending these lectures, or when the lectures included information for future quizzes, attendance increased. When attending these lectures was made contingent upon having completed certain assignments the prior week, no increase in assignment completion was noted and the attendance at the lectures decreased even further. All lectures were given during one class meeting each week. Attendance at the other class meetings during the week remained stable.

A procedure for maintaining student progress in a personalized university course

Ten students in a personalized university course were given target dates for completing each of 26 lessons. The lessons could be completed before those dates, but not after. The first two failures to complete a lesson by the target date led to "warnings"; the next failure required the student to withdraw from the course. When each student's rate of lesson completion was compared with and without target dates, it was found that students completed an average of 1.0 lesson a day with the target-date contingency and 0.3 without it. Individual data indicated that most students did few or no lessons without the contingency. It was concluded that a target-date contingency is an effective method for maintaining student progress in personalized university courses.

The Keller Plan in Science Teaching

A review of evaluative research on the Keller plan establishes the following points: 1) The Keller plan is an attractive teaching method to most students. In every published report, students rate the Keller plan much more favorably than teaching by lecture. 2) Self-pacing and interaction with tutors seem to be the features of the Keller courses most favored by students. 3) Several investigators report higher-than-average withdrawal rates for their Keller sections. The conditions that influence withdrawal and procrastination in Keller courses have been studied, and it seems possible to control procrastination and withdrawal through course design. 4) Content learning (as measured by final examinations) is adequate in Keller courses. In the published studies, final examination performance in Keller sections always equals, and usually exceeds, performance in lecture sessions. 5) Students almost invariably report that they learn more in PSI than in lecture courses, and also nearly always report putting more time and effort into the Keller courses.

The effectiveness of currently enrolled student proctors in an undergraduate special education course

Potential users of Keller's personalized college classroom method might find it impractical to provide student proctors from the ranks of those who had previously mastered the course material. An alternative is to let currently enrolled students proctor and tutor each other. Such a method imposes the burden of showing that its effectiveness is not a function of (1) student collaboration or (2) the effects of "practice" received by students who listen to the performance of others before their own performance. The present study compared students proctored by previously trained students (Control) with students who received proctoring from classmates (Experimental). Experimental group performance was superior to Control group performance. The effects of "practice" and collaboration were ruled out as determinants of the difference between groups. It is hypothesized that the superior performance of the Experimental students was related to their activities as proctors.

Academic responses and attitudes engendered by a programmed course in child development

Both a small course section and a large course section were taught with methods that involved breaking material down into weekly units that had to be mastered by students as indicated by weekly tests. Attendance at lectures was voluntary and students were not tested on lecture material. In a system in which a student could receive only an A or an F for a course grade, less than 2% of the students receiving credit failed to master all material and received Fs. Students in the large course performed better on weekly tests and received fewer Fs than their counterparts in the small course, even though they rated their experience less favorably. Within the large course, the methods of tutorial interview, group discussion, and written assignment were compared in terms of their effectiveness in preparing students for weekly tests. Tutorials and written assignments were superior to group discussions in this regard. Students rated the effectiveness and enjoyability of these three methods in the reverse order from their actual effectiveness for test preparation. Some consequences of lack of congruity between attitude measures and performance measures were discussed.
