LEVEL OF INTERACTIVITY OF VIDEODISC INSTRUCTION ON COLLEGE STUDENTS' RECALL OF AIDS INFORMATION

Experiment 1 confirmed the greater effectiveness of constructed-response interactive videodisc instruction when compared to a click-to-continue or passive viewing formats on posttest recall of AIDS information by 101 college students. Experiment 2 extended the analysis using a counterbalanced (ABAB-BABA) intrasubject design with 4 students in each of three ability groups. The necessity of constructing answers appears to be an important factor in the effectiveness of instructional programs.     

MODIFICATION OF THE EXCESSIVE INAPPROPRIATE CLASSROOM BEHAVIOR OF TWO ELEMENTARY SCHOOL STUDENTS USING HOME-BASED CONSEQUENCES AND DAILY REPORT-CARD PROCEDURES1

Two experiments investigated home-based reinforcement contingencies to control excessive behavior in normal classrooms. Subjects were, respectively, a 12-yr-old fifth-grade boy and a 9-yr-old fourth-grade boy, each in a separate classroom and with a different teacher. Following baseline observations in which observers recorded several categories of student behavior and teacher-student interaction, separate conferences were held including parents of the two children, the principal, teachers, and experimenters. A daily report-card procedure was agreed on, stipulating a one-day suspension from school following three successive “undesirable” daily report cards as well as the supervision of home-based privileges and other reinforcers usually contingent on satisfactory daily reports. Measurements of daily rates of teacher attention indicated no important change in this variable throughout the various experimental conditions. The daily report procedure significantly reduced disruptive classroom behavior. In a second experiment, a teacher-operated timer cued her own time-sample observations. Reliability measures revealed that the teacher could accurately measure the child's behavior while she was teaching the class. The procedure was ultimately successfully expanded to the teacher's total contact hours each day.     

Anti-Poverty,Development, and the Limits of Progress

In this paper I critically engage with Hennie Lötter’s impressive book, Poverty, Ethics and Justice. I discuss his conception of poverty, and offer an interpretation of his claim that poverty is a uniquely human scourge. I exam the various harms of poverty that Lötter discusses. I consider two reasons that he offers for why we have a moral duty to end poverty, and I argue that the reason based on what we can justify to others if we take their human dignity seriously is most compelling. Finally, I argue that Lötter overemphasizes of the moral importance of aid and downplays in the importance of the justice of institutional and structural change. I close by considering the prospects for social equality given our experience of capitalist development as a means for poverty eradication. I consider the moral importance of limits to the achievement of robust equality.     

Support for lateralization of the Whorf effect beyond the realm of color discrimination

Recent work has shown that Whorf effects of language on color discrimination are stronger in the right visual field than in the left. Here we show that this phenomenon is not limited to color: The perception of animal figures (cats and dogs) was more strongly affected by linguistic categories for stimuli presented to the right visual field than those presented to the left. Moreover, the magnitude of the visual field asymmetry was reduced when demands on verbal working memory were increased by a secondary task. This reduction did not occur when the secondary task imposed demands on spatial working memory. Taken together, these results demonstrate that the lateralized Whorf effect may be quite general, reflecting an interaction of linguistic and perceptual codes primarily in the left hemisphere.     

Successful women and women's colleges: Is there an intervening variable in the reported relationship?

This study examined the relationship between career success and the baccalaureate degree origin of women. Analyses of data collected on the educational backgrounds of 126 successful women confirmed previous findings that graduates of women's colleges were more likely to attain career success than graduates of coeducational institutions. Results also identify graduate education as a possible intervening variable in the relationship.The authors wish to thank Dr. Elizabeth Tidball for providing us invaluable data she accumulated for previous studies.     

Suffering and the sovereignty of God: one Evangelical's perspective on doctor-assisted suicide.

This paper presents my personal convictions, as an Evangelical, regarding the absolute impropriety of doctor-assisted suicide for Christians. They have been "bought with a price" and are owned by Another. Hence, they must always strive to glorify God in their bodies, both in life and in death. Although they crave the well-being of temporal health, when they are ill seek healing or relief, and may well recoil even from the thought of suffering and dying, they should realize that their values and priorities must be rooted in biblical truths and that their well-being is eternal and not temporal, spiritual and not material. As Christians, their attitudes and responses to suffering and dying must be molded by the reality that their Creator and Sovereign will cause all things to work together for their good and that their Lord has called them into a fellowship of His suffering in which they are sustained by dependence upon Him. Hence, for Christians to take their lives in order to escape from the trials and testings ordained by Him would be a failure of love and a breach of trust.     

THE EFFECTS OF ACCESS TO SPECIAL ACTIVITIES ON THE PERFORMANCE IN FOUR CATEGORIES OF ACADEMIC TASKS WITH THIRD-GRADE STUDENTS1

An ABAB experimental design was used to evaluate the effects of access to recreational activities contingent on the completion of at least 80% of academic tasks assigned daily. Requirements in four task categories (writing, copying words, spelling, and dictionary skills) were specified daily and students were required to complete at least 80% of the requirements in each category correctly in order to participate in daily recreational activities. The procedure produced reliable and educationally important increases in the task performance of all 19 third-grade students in the study. Most of the difference in the performance of each child between experimental conditions was on the spelling and dictionary tasks, although there were also improvements on the writing and words-copied tasks for those students showing the greatest overall change in performance. The procedure was easily implemented by the teacher alone, required only materials and equipment typically found in elementary schools, and produced changes in performance important enough to the teacher that she continued to use the basic procedure after the evaluation program was terminated.
