Teenage pregnancy: a small comparison group of known mothers

To obtain confirmation of the findings of the authors' earlier comparison of ever-pregnant and nonpregnant Black high school students from Tennessee, 16 students confirmed to be pregnant were substituted for the 33 subjects in the original study whose pregnancy status was based solely on self-report. The nonpregnant control group of 251 teens was utilized in both analyses. Although the confirmed pregnant group was too small to repeat the regression analysis, striking concordance of findings between the 2 studies emerged for all dependent variables except the Eysenck Personality Questionnaire anxiety scale. The lower anxiety scores recorded among subjects in the original study may be either a statistical artifact or a reflection of the fact that these pregnant teens remained in school while subjects in the second study were enrolled in programs centered around their pregnant status. Sexual activity scores were strong or moderate significantly more often in both groups of pregnant teens compared to their nonpregnant counterparts. Interesting was the finding that 81% of pregnant teens regarded romance novels and soap operas to be accurate portrayals of real-life dating relationships compared to only 49% of nonpregnant teens. On the other hand, only 56% of the pregnant subjects regarded their own relationships to have this romantic quality. In a future study, the role of such uncritical romantic ideals in adolescent pregnancy risk will be investigated in a larger sample.     

Learning by Doing: Teaching Decision Making through Building a Code of Ethics

Applying abstract ethical principles to the practical business of building a code of applied ethics for a technical communication department teaches students that they share certain unarticulated or even unconscious values that they can translate into ethical principles. Combining abstract theory with practical policy writing can teach technical communication students to become increasingly aware of ethical actions without restricting ethics solely to abstractions or rules.     

Deaf teacher candidates in hearing classrooms: a unique teacher preparation program

An undergraduate teacher education program at Gallaudet University prepares deaf students in "regular" education. This includes a required full-time internship with hearing students (assisted by sign language interpreters). Graduates then continue in a master's degree program in deaf education, thus acquiring dual certification. Several studies indicate that these deaf candidates progress through the same developmental stages as hearing candidates and that they develop high expectations for deaf learners. Issues related to implementing such a program are discussed.     

Characteristics of child sexual abuse treatment programs

Within the professional community, a vast number of sexual abuse treatment programs have emerged to meet the needs of victims and their families. Significant variations among these programs can be observed due to differences in philosophy, system context, client focus, problem definition, and the treatment strategy adopted. Unfortunately, little comparative information is available regarding the operation of different programs and, more importantly, their relative treatment effectiveness. This article presents the findings from a nationwide survey of 553 sexual abuse treatment programs. The survey focused on program context, client, and service characteristics. Overall it was found that most programs are affiliated with a larger public or private agency, focus on treating victims, and rely on a combination of individual, family, dyad, and group therapy approaches.     

A Feedback Procedure for Teacher Trainees Working with Parent Tutors of Reading

Abstract In this pilot study, four third‐year teacher trainees were trained to give feedback to parents who were tutoring their own children in reading using the Pause Prompt and Praise procedures. The trainees learnt to teach the procedures to the parents and then to give feedback by prompting parents to remember and explain their own tutoring behaviours. Baseline measures showed that when trainees were asked to help parents in any way they could to implement the procedures, they used very intrusive forms of prompts. Following training trainees used much less intrusive forms of prompts, giving parents more opportunity to remember and explain their own tutoring behaviours. It was argued that less intrusive forms of prompting when giving feedback may have been of more assistance to parents in learning the procedures than more intrusive forms of prompting, since parents may have learned to become more independent of trainee support. This, in turn, may have contributed to the substantial gains in children's reading levels which occurred.     

Response-cost punishment with pigeons: Further evidence of response suppression via token loss

Four pigeons responded on a two-component multiple token-reinforcement schedule, in which tokens were produced according to a random-interval 30-sec schedule and exchanged according to a variable-ratio 4 schedule in both components. To assess the effects of contingent token loss, tokens were removed after every second response (i.e., fixed-ratio 2 loss) in one of the components. Response rates were selectively lower in the loss components relative to baseline (no-loss) conditions, as well as to the within-condition no-loss components. Response rates were decreased to a greater degree in the presence of tokens than in their absence. To control for the effects of changes in the density of token and food reinforcement, two parts consisted of additional conditions where food density and token loss were yoked to those in a previous loss condition. In the yoked-food condition, tokens were produced as usual in both components, but the overall density of food reinforcement in one of the components was yoked to that obtained during a previous token-loss condition. In the yoked token-loss condition, tokens were removed during one component of the multiple schedule at a rate that approximately matched the obtained rate of loss from a previous token-loss condition. Response rates in these yoked components were less affected than those in comparable loss components, despite similar densities of token, exchange, and food reinforcement. On the whole, the results support the conclusion that contingent token loss serves as an effective punisher with pigeons.

Approaches to Study of Distance Education Students

The'Approaches to Studying'inventory of Ramsden and Entwistle (1981) was administered to groups of external and internal students at Capricornia Institute and the Tasmanian College of Advanced Education. Factor analysis revealed a similar factor structure for external students to that of the total sample. This finding, together with analysis of variance data, is taken as evidence that it is valid to use the inventory and the associated theories on learning styles with distance education students. Analysis of variance data showed differences in learning styles for older students. The implications of this finding for the design of distance education courses are discussed.
