Associations between sexually experienced adolescents' sources of information about sex and sexual risk outcomes

The objective of this study was to describe prevalent informal sources of information about sex and examine associations between informal sources of information about sex and sexual risk outcomes among sexually experienced adolescents. Work involved the secondary analysis of data from the Minnesota Student Survey, a statewide survey to monitor priority risk and protective health behaviors. The study sample included 22,828 sexually experienced adolescents aged 13–20 years. Multivariate logistic regression analyses examined associations between adolescents' informal sources of information about sex and three sexual risk outcomes. Peers and siblings were the most commonly reported source of information about sex. Ninth-graders who reported parents or parents plus peers/siblings as a source of information about sex had significantly lower odds of having multiple sex partners in the past year. Ninth-graders who reported any informal source of information about sex had significantly lower odds of unprotected intercourse at last sex. Ninth-graders and 12th-graders who reported any informal source of information about sex had significantly lower odds of lifetime pregnancy involvement. Findings suggest information about sex from people in adolescents' everyday lives has the potential to diminish the likelihood of involvement in sexual risk behaviors. To maximize effectiveness, formal sex education programs should engage informal sources of information about sex in adolescents' everyday lives.     

Scientific Visuals,Language, and the Commercialization of a Scientific Idea: The Strange Case of the Prion

In the field that investigates infectious brain diseases such as mad cow disease, the verbal and visual packaging of scientific visuals associated with identifying the agent, prion, its processes, and structure served the community ritual of establishing belief in a highly unorthodox phenomenon. Visual promotion fed into cultural expectations of single agents and simple processes, even though the actual agency and disease process have proven highly complex and perhaps unknowable.     

Making Ends Meet: Bringing Bilingual Education and Mainstream Students Together in Preservice Teacher Education

In some institutions offering certification for bilingual education and ESL teachers, the corresponding mainstream programs do little to ready their students to work effectively with language minority children. Yet today's mainstream classrooms are linguistically and culturally diverse, and all teachers must appreciate the role of language and culture in teaching and learning. This study describes one effort to consciously combine preservice bilingual and mainstream education teachers in a bilingual education methods cohort. Students reported promising gains in cross-cultural understanding and in cross-program appreciation. Some losses took place as well, however, and further innovation and research are needed in order to ensure that such efforts to combine programs strengthen, but not weaken, each program.     

Steps to Opening Scientific Inquiry: Pre-Service Teachers’ Practicum Experiences with a New Support Framework

This qualitative multiple-comparative case study investigates (1) The reported experiences and impressions of four pre-service teachers (PTs) on practicum placement in four different classrooms (grades 1–9) where a new Steps to Inquiry (SI) framework was being utilized to support students conducting open inquiry; (2) The relative dispositions of the PTs toward conducting open inquiry, as indicated by their core conceptions regarding science, the purpose of education, effective teaching, and the capacity of students. Findings indicate that (1) although there were differences in the experiences of the four PTs, all four had an opportunity to observe and/or facilitate students conducting open inquiry with the SI framework, and after the practicum, all of them reported that they would like to include open inquiry in their own classrooms in the future; (2) one PT already possessed core conceptions indicative of a favorable disposition toward open inquiry before the placement; another altered her core conceptions substantially toward a favorable disposition during the placement; a third altered her conceptions regarding the capacity of students; and one PT maintained core conceptions indicative of a disposition that was not favorable to open inquiry despite the pronouncements that she would like to conduct open inquiry with students in their own future classroom. Possible reasons for the differences in the responses of the four pre-services teachers to the practicum placement are discussed.     

The Impact of More,Better, Faster,Cheaper: How the PCC Influenced Everything That Followed

Abstract

The beginnings and the early years of the Program for Cooperative Cataloging (PCC) had a profound impact on the approach taken to cataloging in North America and around the world. The commitment to standards, cooperation, and expanded access also had an impact that went far beyond cataloging operations. One library dean traces the evolution of her vision and contemplates how the PCC’s principles have shaped her entire career and have affected the libraries in which she has worked.     

Uncovering the Evidence: Faculty Perceptions of Distance Library Services

Usage statistics are a regular part of assessment but the lack of context leaves librarians pondering the reasons for fluctuations in use. Through development of an online survey, we examined faculty perceptions, knowledge, and use of distance library services to support online courses. Responses provided much needed context and helped to determine priorities and direction for services. While this survey was a useful marketing tool, results emphasized that the greatest need was for ongoing communication with faculty to increase awareness of services provided.     

Examining the Psychometric Quality of the National Board for Professional Teaching Standards Early Childhood/Generalist Assessment System*

The purpose of the study was to examine the psychometric quality of the National Board for Professional Teaching Standards (NBPTS) Early Childhood/Generalist assessment system. Rating data from the 1997–1998 assessment were analyzed using the FACETS (Linacre, 1998) computer program. The assessment system's 10 exercises work together to define a unidimensional accomplished teaching variable. There is little evidence of multidimensionality in the data, and none of the exercises appear to function in a redundant manner. The exercise set succeeds in defining several statistically distinct levels of accomplished teaching among the candidates. Overall, most candidate rating profiles show consistent performance across the exercises. While assessors differed somewhat in severity, most used the 12-point rating scale consistently. Although the range in assessor variability tends to be moderate, assessor severity does influence the number of candidates that can bank individual exercises. (If a candidate's total scaled score does not meet or exceed the NBPTS performance standard of 275, the candidate can bank scores on exercises in which the candidate received a final score of 2.75 or greater. If the candidate reapplies for certification in the next three years, the candidate does not have to retake banked exercises.)     

Influences on Student Cognitions About Evaluation

Interviews on two occasions with 71 Grade 2, 4 and 6 students in a multi-ethnic setting in Toronto, Canada, found that student cognitions about evaluation mediated the relationship between evaluation and achievement. Parents, peers and student characteristics influenced student cognitions about evaluation. Parents identified the evaluation dimensions their children should attend to, raised student aspirations, stated how well student work attained standards and recommended actions children should take in response to the evaluation. Peer interpretations influenced whether a given performance was viewed as superior or inferior. Older student peers focused attention, to a greater extent than parents, on specific aspects of student performance that could be ameliorated through self-remediation. Children became more sophisticated evaluation consumers as they grew older. Females processed evaluation data more productively than males. There were few cultural differences in response to evaluation. Students responded to traditional and alternate evaluation in very similar ways.
