The Royal Medical Society of Edinburgh: sale of its library at Sotheby's

The library of the Royal Medical Society of Edinburgh, which has been in existence for nearly 250 years, was sold by Sotheby & Co. of London at three auction sales during 1969. The author describes her attendance at the three sales, with emphasis on the most valuable items sold and the considerable acquisitions made for the Middleton Medical Library of the University of Wisconsin. Concluding observations concern some of the practical problems of acquiring antiquarian books at auction.     

The abuse-related beliefs questionnaire for survivors of childhood sexual abuse

OBJECTIVE: To evaluate the psychometric properties of a new measure, the Abuse-Related Beliefs Questionnaire (ARBQ), designed to assess abuse-related beliefs among adult survivors of childhood sexual abuse (CSA). Study 1 examined the structure of the scale, and Study 2 evaluated its reliability and validity. METHOD: One hundred and seventy female CSA survivors recruited into a group psychotherapy intervention study were administered the ARBQ in Study 1. A subsample of 45 women completed the ARBQ again 12 months later. In Study 2, 70 women from a health maintenance organization who identified themselves as survivors of CSA completed the ARBQ along with the Trauma Symptom Checklist-40 (TSC-40) and the Symptom Checklist 90R (SCL-90-R). RESULTS: Three reliable ARBQ subscales emerged in Study 1: Guilt, Shame, and Resilience. Twelve-month test-retest reliability was high (r=.60-.64). The internal consistency of the subscales was further supported in Study 2, and validity was demonstrated by moderate to high correlations with the distress measures. CONCLUSIONS: The results indicate that the ARBQ has good psychometric characteristics, supporting the feasibility of its use in measuring abuse-related beliefs in research on survivors of CSA. A next step for validation of the ARBQ would be to evaluate its sensitivity in measuring changes in studies of interventions for treating CSA survivors.     

CALCULUS STUDENTS’ AND INSTRUCTORS’ CONCEPTUALIZATIONS OF SLOPE: A COMPARISON ACROSS ACADEMIC LEVELS

This study considers tertiary calculus students’ and instructors’ conceptualizations of slope. Qualitative techniques were employed to classify responses to 5 items using conceptualizations of slope identified across various research settings. Students’ responses suggest that they rely on procedurally based conceptualizations of slope, showing little evidence of covariational reasoning. In contrast, instructors’ responses demonstrated a multi-dimensional understanding of slope as a functional property, which applies to real-world situations and plays an integral role in the development of key calculus concepts. While relatively diverse, the instructors’ responses seldom reported determining increasing or decreasing trends of a line from its slope. This conceptualization was used frequently by students and could help them better understand how slope ties to positive and negative derivatives. The most frequently used conceptualizations for students in this study align with past research findings on the emphasis of the secondary mathematics curriculum, supporting the possibility of cultural influences (academic and geographic) on individuals’ conceptualizations of slope. Thus, this study provides valuable insight into conceptualizations of slope and provides direction for future research on slope and the broader topic of cultural influences on mathematical meaning.     

Support and Challenge in Mentoring: A CaseStudy of Beginning Elementary Teachers and Their Mentors

In a recent Journal of Early Childhood Teacher Education article, the author reported on a single case of a successful mentor–beginning teacher pairing that was derived from a larger qualitative study (Certo, 2005 Certo, J. 2005. Support, challenge, and the two-way street: Perceptions of a beginning second grade teacher and her quality mentor. Journal of Early Childhood Teacher Education, 26(1): 3–21. [CSA][Taylor & Francis Online] , [Google Scholar]). The purpose of this article is to report findings from that larger investigation. Three Virginia elementary 1^st-year teachers and their mentors were interviewed in September, December, and February. Beginning teachers also kept journals of reflections about challenges in 1^st-year teaching and the presence, nature, and impact of mentoring activities. Perceptions of mentor activities and the perceived impact on beginning teachers’ thinking and professional development are described using Daloz’s support and challenge model (1988) Daloz, L. 1988. The story of Gladys who refused to grow: A morality tale for mentors. Lifelong Learning, 11(4): 4–7. [CSA] [Google Scholar]. Mentors provided a balance of support and challenge activities, and beginning teachers reported being impacted by their mentors in numerous ways, from classroom management to adoption of new instructional approaches. These cases may be useful to practitioners as models of effective practice.     

Dynamic dictionary updating

A method for updating the dictionary in a dynamic information retrieval system is presented. It is shown that as a collection changes through addition and deletion of documents, the appropriate set of index terms may be determined without complete periodic regeneration of the dictionary. Results are presented for experiments involving a complete change in collection membership, with the dynamic dictionary updating methods shown to be effective.     

Species-specific defense reactions in escape-from-fear situations

Five experiments are reported in which rats were given CS-shock pairings and then permitted, in the absence of shock, to perform a hurdle-jump response that led to CS offset. In Experiment 1–4, the animals failed to learn the required response. Although several procedural variations were employed, the experimental groups continued to perform no better than backward-conditioned controls. In Experiment 5, some animals were punished for remaining immobile during a single trial at the start of hurdle-jump training. These animals performed significantly better than nonpunished controls and better than any group in Experiments 1–4. The results support the idea that the major role of the CS in escape-from-fear situations is to activate an innate motivational system which chooses between the species-specific defense reactions of freezing and fleeing.     

Exploring the Meaning and Paths of Advocacy for Undocumented Students’ Access to Education

There is widespread national debate over how to address and advocate for undocumented immigrants in the United States. Education is key to the economic, occupational, and social mobility of young unauthorized immigrants, but policies and practices can hinder or open their access to education. Educators pursue a range of activities to support undocumented students in school. This article identifies the conceptualizations, strategies, and thought processes of educators who advocate for undocumented students. The results reveal that advocates’ backgrounds, resources, goals, identity, and the communities in which they advocate influence their perceptions and practices of advocacy.     

Cross-cultural comparability of noncognitive constructs in TIMSS and PISA

Abstract

Noncognitive assessments in Programme for International Student Assessment (PISA) and Trends in International Mathematics and Science Study share certain similarities and provide complementary information, yet their comparability is seldom checked and convergence not sought. We made use of student self-report data of Instrumental Motivation, Enjoyment of Science and Sense of Belonging to School targeted in both surveys in 29 overlapping countries to (1) demonstrate levels of measurement comparability, (2) check convergence of different scaling methods within survey and (3) check convergence of these constructs with student achievement across surveys. We found that the three scales in either survey (except Sense of Belonging to School in PISA) reached at least metric invariance. The scale scores from the multigroup confirmatory factor analysis and the item response theory analysis were highly correlated, pointing to robustness of scaling methods. The correlations between each construct and achievement was generally positive within each culture in each survey, and the correlational pattern was similar across surveys (except for Sense of Belonging), indicating certain convergence in the cross-survey validation. We stress the importance of checking measurement invariance before making comparative inferences, and we discuss implications on the quality and relevance of these constructs in understating learning.     

Addressing 21st-century crises through children’s literature: picturebooks as partners for teacher educators

ABSTRACT

Teacher educators might consider using high-quality picturebooks as partners to help teacher candidates understand and navigate today’s painful world realities. From a critical perspective, these books also have the potential to reflect and shape empathy and action in regard to these difficult situations. This piece includes a rationale for using picturebooks to address human crises, findings related to a study of 21st-century representations of crises in picturebooks, and implications for sharing these books as pedagogical partners to engage with teacher candidates. To this end, we conducted a content analysis of recent 21st-century fictional picturebooks depicting human crises. Topics related to refugee status, poverty, homelessness, and hunger were analyzed to reveal common themes across these books related to persistence, courage, caring, and hope. Teacher educators who are eager to address 21st-century disasters, many of which are presented in sensitive and accessible ways in recent touchstone picturebooks, can find a ready and capable partner in these powerful picturebooks to help readers understand and navigate these human crises.     

What Counts and How: Mathematics Teaching in Culturally, Linguistically, and Socioeconomically Diverse Urban Settings

This article presents findings from an ongoing study of urban teachers' efforts to embrace mathematics reform with student populations that are culturally, linguistically, and socioeconomically diverse (CLSD). We investigate the teacher's role in providing accessible and valuable mathematical learning opportunities to diverse students. Through narrative vignettes of practice and analyses of the personal and intellectual resources teachers draw on in CLSD contexts, we examine the challenges and possibilities two third-grade teachers face as they attempt such reform. One teacher's strengths were in making cultural connections with her students; the other's strengths were in pursuing complex and meaningful mathematics with her students. Building on our analysis, we offer a framework for examining the work of attending to mathematical and cultural issues simultaneously. Our findings suggest that such work is complex; however, teachers are seldom supported in their efforts to integrate these two perspectives. Our aim is to examine the dimensions of culturally relevant mathematics teaching and explore where the fields of mathematics and bilingual-bicultural education need to speak to one another.
