An Empirical Investigation Demonstrating the Multidimensional DIF Paradigm: A Cognitive Explanation for DIF

Differential Item Functioning (DIF) is traditionally used to identify different item performance patterns between intact groups, most commonly involving race or sex comparisons. This study advocates expanding the utility of DIF as a step in construct validation. Rather than grouping examinees based on cultural differences, the reference and focal groups are chosen from two extremes along a distinct cognitive dimension that is hypothesized to supplement the dominant latent trait being measured. Specifically, this study investigates DIF between proficient and non-proficient fourth- and seventh-grade writers on open-ended mathematics test items that require students to communicate about mathematics. It is suggested that the occurrence of DIF in this situation actually enhances, rather than detracts from, the construct validity of the test because, according to the National Council of Teachers of Mathematics (NCTM), mathematical communication is an important component of mathematical ability, the dominant construct being assessed. However, the presence of DIF influences the validity of inferences that can be made from test scores and suggests that two scores should be reported, one for general mathematical ability and one for mathematical communication. The fact that currently only one test score is reported, a simple composite of scores on multiple-choice and open-ended items, may lead to incorrect decisions being made about examinees.     

The locker room : Eroticism and exoticism in a polyphonic text

Critical race theory now encompasses a polyphonic telling of story in which multiple, shifting identities are seen in relation to each other and situated within historical contexts. Locating the fictive voice of an administrator forced to deal with change at a small private university, the article begins with a flashback to confrontations demanding that he reexamine his positions in relation to both work and social life. The second part of the article is an analytic discussion of the voices of narrator and other actors and concludes with a critical reconceptualization of polyphony. Much in the same way that critical race theorists have injected story-telling into legal scholarship in order to deconstruct and then reconstruct knowledge, the authors urge education researchers to move away from methodologies and systems of analysis that derive from white liberal discourse and ironically serve to maintain the status quo by leaving in place conservative structures and reward mechanisms.     

Promoting complex systems learning through the use of conceptual representations in hypermedia

Studying complex systems is increasingly important in many science domains. Many features of complex systems make it difficult for students to develop deep understanding. Our previous research indicated that a function‐centered conceptual representation is part of the disciplinary toolbox of biologists, suggesting that it is an appropriate representation to help students develop deep understanding. This article reports on the results of two experiments that investigate how hypermedia using a conceptual representation influences pre‐service teachers' and middle school students' learning of a complex biological system, the human respiratory system. We designed two versions of instructional hypermedia based on the structure–behavior‐function conceptual representation. One hypermedia was function‐centered which emphasized the function and behavior of the system, whereas the other was focused on the structure of the system. We contrasted the instructional effectiveness of these two alternative conceptual representations. The results of both studies indicated that participants using the function‐centered hypermedia developed deeper understanding than those using the structure‐centered version. This proof‐of‐concept study suggests that the function‐centered conceptual representation is a powerful way to promote complex systems understanding. © 2009 Wiley Periodicals, Inc.

Changing attitudes and intentions related to doping: An analysis of individual differences in need for cognition

ABSTRACT

Research has shown that athletes’ attitudes towards the use of banned performance-enhancing substances are reliable predictors of their intentions to use these substances, which in turn can be relevant predictors of their actual doping behaviours. Despite the important role played by attitudes and intentions in doping, research analysing how to change those attitudes and intentions is relatively scarce. The present study examined how individual differences in Need for Cognition (NC, Cacioppo & Petty, 1982) influenced doping-related attitude change and subsequent behavioural intentions. Participants were randomly assigned to read a persuasive message either against or in favour of legalising the use of several banned substances, including anabolic androgenic steroids (AAS) and Erythropoietin (EPO). In addition, participants completed the NC scale, and finally reported their attitudes and behavioural intentions regarding the legalisation proposal. As hypothesised, results showed that participants who received an anti-legalisation message had significantly more unfavourable attitudes towards the proposal than participants who received a pro-legalisation message, regardless of NC. However, as predicted, NC moderated the relationship between individuals’ attitudes and their intentions. That is, high-NC participants showed greater attitude-intention correspondence than low-NC participants.     

Using electronic communication to bridge the research to practice gap among mentoring professionals

The field of mentoring includes a broad base of stakeholders, such as researchers and practitioners who implement mentoring programs. The research-to-practice gap is an ongoing area of concern in many fields of social science including mentoring. One reason for this is that researchers and practitioners often operate in isolation. Technology is playing an ever-increasing role in the professional lives of practitioners and researchers, therefore, this study explored the engagement of both groups through the YOUTHMENTORING list serve; a resource provided by the University of Illinois-Chicago. Through a comprehensive qualitative study of list serve content, connections, and engagement it was found that the YOUTHMENTORING list serve promoted collaboration among stakeholders. Members found the resource to be valuable to their practice. Implications for the field and future research are discussed.     

Assessment of health-care professionals’ knowledge and attitudes on sexuality and aging: an integrative review

ABSTRACT

This study aims to establish an understanding of (a) health-care professionals’ knowledge and attitudes; and (b) tools used to assess sexuality in older people living with/(out) dementia and those identified as lesbian, gay, bisexual, trans, or intersex (LGBTI) individuals. An integrative review of the literature, as registered on the PROSPERO international Prospective Register of Systematic Reviews (CRD42019129589), was conducted. A comprehensive and systematic literature search was performed for the period between 2009 to 2019 across eight electronic databases: CINAHL, PubMed, MEDLINE, Web of Science, Cochrane library, Embase, PsycINFO, and Scopus, together with a manual search of reference lists. Screening of titles, abstracts, and full texts of eligible studies plus quality appraisal (using the Mixed Methods Appraisal Tool) were independently conducted by two reviewers with disagreements resolved via discussion with a third reviewer. Nineteen articles were reviewed with three themes identified from the synthesis: 1) varying knowledge and attitudes amongst health-care professionals; 2) needs for professional development opportunities and support from workplace and 3) lack of recent validated tools to assess knowledge and attitudes. Health-care professionals’ knowledge and attitudes toward sexuality in older people living with/(out) dementia and those identified as LGBTI individuals are varying. Sexuality education and professional development training are needed to enhance their knowledge and attitudes and build skills in order to manage sexuality concerns. Current assessment tools are inadequate, highlighting the need for an appropriate assessment tool to be developed.     

Child and adolescent abuse and subsequent victimization: a prospective study

OBJECTIVE: We investigated the possible reciprocal relationship between victimization experiences and psychological functioning by assessing abuse experiences in childhood, adolescence, and during a 2-month follow-up period. METHOD: At the beginning of the study (Time 1), abuse histories, trauma and depressive symptoms, and interpersonal functioning were assessed in 551 college women. Subsequent victimization experiences and psychological outcomes were assessed at the follow-up (Time 2). RESULTS: Path analyses indicated that verbal abuse by the mother and father were predictive of various psychological outcomes as measured at Time 1 and emerged as the only significant predictors of adolescent dating violence. Adolescent dating violence subsequently predicted the experience of dating violence during the 2-month follow-up period. Paternal physical abuse predicted adolescent sexual victimization which subsequently predicted all symptom measures at Time 1. Conversely, the experience of adolescent physical dating violence was not predictive of any of the symptom measures at Time 1. For those women who experienced dating violence during the follow-up, however, the severity of their abusive experiences was related to both depression and interpersonal problems assessed at Time 2. In comparison, for those women who experienced sexual victimization during the follow-up period, the severity of their abusive experiences was related to trauma symptoms. Interpersonal problems emerged as both an aftereffect of adolescent sexual victimization experience and a predictor of a subsequent sexual victimization experience during the follow-up. CONCLUSIONS: Given that emotional abuse emerged as a predictor of adolescent dating violence and psychological outcomes, researchers and clinicians need to continue to explore this problem. Further, it is important to assess how interpersonal problems contribute to the risk of subsequent sexual victimization and to try to break the cycle between adolescent abuse experiences and subsequent physical and sexual assaults.
