Wise: Web Interface for Statistics Education

The Web Interface for Statistics Education (WISE) project includes a World-Wide Web site to support the teaching of introductory social-science statistics courses. The site provides easy access to data bases, archived discussion lists, electronic journals, links to other sites focused on relevant statistics topics, and it includes a prototype of an on-line tutorial. The tutorial, which is the focus of the current paper, is designed to capitalize on special capabilities offered by the Web. The easy linkage between Web pages provides support for a highly interactive tutorial, which uses “failure-based” learning and immediate feedback. Students rated the tutorial as easy to use and indicated that it would have improved their initial statistics course.     

Content validity: A neglected strategy for developing managerial selection tests?

There is a lack of quick, valid, and cost effective methods for selection of low-and mid-level managerial personnel. Using content-valid methods to develop managerial selection instruments may reap substantial benefits for applicants as well as for the organizations using such tools. To this end, based upon extensive job analysis, a content-valid managerial selection test was developed. Criterion-based validity collected on the new instrument suggested that an instrument developed using content-valid procedures can also show acceptable levels of criterion validity.     

Rights, justice, and duties to provide assistance: a critique of Regan's theory of rights

In his monograph, The Case for Animal Rights (University of California Press; 1983), Tom Regan seeks to develop an alternative moral theory to utilitarianism, and to apply it to the question of animal rights, including animal experimentation. Here Jamieson presents an overview of Regan's theory and critically examines areas in which he, Jamieson, believes it to be most problematic. He argues that Regan's theory encounters difficulties in its account of our duties to render assistance and its principles for overriding rights. Jamieson concludes that Regan has failed to develop a "compelling and dramatic alternative to utilitarian theories" and that most plausible revisions of his theory lead back in the direction of utilitarianism.     

Intentional explanations and radical theories of education

In this paper I argue that Marxist studies of schools have overlooked the power of intentional explanations to explain schooling practices and policies. This oversight is at least in part due to many radical analyses failing to distinguish between explaining the acquisition and persistence of beliefs and determining the social consequences that follow from acting on beliefs. I further contend that radical researchers examining schooling practices must develop a more rigorous and refined conception of capitalist class interests.     

Informant impressions of retardate personality: reliability with extraversion, emotionality, toughmindedness

To assess extraversion, emotionality and toughmindedness among retarded persons with limited linguistic skills the 18-item Personal Reactions and Habits Questionnaire (PRHQ) was created. The responses of 2 interviewed informants, each well acquainted with a target person, are summed to obtain scores for each of the personality factors identified by Eysenck and Eysenck (1975). To establish the reliability of this procedure 4 interviewers inquired of 35 informants about a total of 54 target Ss of a wide range of mental retardation and living variously in the natural home, a group home or in a large state-operated institution. One-week test-retest reliability coefficients, e.g. r=0.93 for Extraversion, r=0.86 for Emotionality and r=0.92 for Toughmindedness, suggest the PRHQ to be a promising instrument for research on personality of Ss unable to provide self-reports. The possible use of the PRHQ to assess concordance of self-reports with personality impressions of others is also discussed.     

Therapeutic rationale,monetary incentive and fear behavior: a methodological note on analogue research

Analogue research has been questioned as a means of evaluating clinical procedures (e.g. Cooper, Furst and Bridger, 1969). A major criticism has been the failure to include adequate controls. Placebo conditions have varied markedly in their similarity to active treatment procedures (Caputo, Nau and Borkovec, 1973), have not provided equally credible therapeutic rationales (Borkovec and Nau, 1972), and have thus generated differing expectancies and demands for improvement.To evaluate a therapy procedure, a comparison condition is needed in which no treatment intervenes between pre- and post-test measures, yet which provides adequate incentive for improvement. Rimm and Mahoney (1969) used a ‘contingent reinforcement’ placebo condition in which tokens, exchangeable for money, were dispensed for improvement in a graded approach to a feared stimulus. Little improvement occurred, suggesting a lack of effectiveness of money alone in improving approach behavior. However, as no therapeutic rationale was presented, it is likely that little expectancy for improvement occurred.The present study provided a ‘no treatment’ condition in which Ss participated in three test sessions with no intervening treatment procedure. Unlike Rimm and Mahoney (1969), two conditions provided a rationale explaining why Ss had maintained their fear and why no real therapy was needed to eliminate it. Also, monetary reward (a $5.00 bill rather than tokens) was dispensed only upon picking up the feared object. A follow-up session assessed the lasting effects of rationale and monetary incentive in the absence of extrinsic reinforcement. Thus, the present study attempted to determine the effect of therapeutic rationale and/or the possibility of receiving money, in the absence of ‘therapy’, on subclinical fear.     

Primary prevention of behavior problems in mexican-american children

A primary prevention program, the Houston Parent-Child Development Center, directed towards infants and their parents, has effectively reduced the frequency of behavior problems for these children 5 to 8 years after the program's completion. Teacher ratings showed significantly fewer acting-out, aggressive behaviors for program children. Ratings of classroom behaviors found program children significantly less hostile and more considerate than control boys. This appears to be the first primary prevention program to have demonstrated effectiveness in reducing behavior problems over such a long time.     

Effect of task on mother-child interaction results

The influence of task on behavior in mother-child interaction was studied. Five tasks varying in degree of structure and difficulty were used in mothers' interactions with their children at 24 and 36 months of age. Child competence was assessed through several tests. Families that had participated in an extensive parent-education program were compared with randomly assigned controls. Interactions were videotaped and rated on scales. Results indicated that there were no task differences in ability to discriminate groups and tasks seldom were found to be differentially related to child competence. Task stability over time yielded some differences.This paper was presented at the American Educational Research Association meeting in Boston, April 1980.
