Measurement Invariance in International Surveys: Categorical Indicators and Fit Measure Performance

In spite of the challenges inherent in making dozens of comparisons across heterogeneous populations, a relatively recent interest in scale-score equivalence for non-achievement measures in an international context has emerged. Until recently, operational procedures for establishing measurement invariance using multiple-groups analyses were typically supported with research that was limited in scope to few groups and relatively small sample sizes. Recent research that examined situations more representative of international surveys recommended some revisions to typically used fit measures. The current study extends this research and evaluates the performance of several fit measures when data are assumed to have an ordered categorical, rather than the typically assumed continuous, scale. Using a simulation study based on empirical results, findings indicated that classic measures and associated criteria were either unsuitable in a large-group and varied sample-size context or should be adjusted, particularly when observed variables were not normally distributed. We provide specific recommendations for revising currently used criteria for evaluating overall and relative fit based on the chi-square test, root mean-squared error of approximation, and comparative fit index (CFI).     

Minds, modules, and meta-analysis

Wellman and colleagues' meta-analysis of performance on the false-belief task is methodologically useful, but it does not lead to any theoretical progress concerning the nature of the mechanisms that underlie the existence and development of "theory of mind." In particular, the results of this meta-analysis are perfectly compatible with "early competence" accounts that posit a specific, innate, and possibly modular basis for theory of mind. The arguments presented by Wellman and colleagues against such views stem not from their meta-analytic data, but from mistaken assumptions regarding the requirements of such theories (e.g., that there exist manipulations that improve performance only, or to a greater degree, in young children). Contrary to what Wellman and colleagues claim, their meta-analysis, while consistent with conceptual change, does not lend any new support for such theories.     

Six-month-old infants' categorization of containment spatial relations

Six-month-old infants' ability to form an abstract category of containment was examined using a standard infant categorization task. Infants were habituated to 4 pairs of objects in a containment relation. Following habituation, infants were tested with a novel example of the familiar containment relation and an example of an unfamiliar relation. Results indicate that infants look reliably longer at the unfamiliar versus familiar relation, indicating that they can form a categorical representation of containment. A second experiment demonstrated that infants do not rely on object occlusion to discriminate containment from a support or a behind spatial relation. Together, the results indicate that by 6 months, infants can recognize a containment relation from different angles and across different pairs of objects.     

Becoming a physician: The influence of the undergraduate experience

This study employed a national sample of college students who initially aspired to be, or later became, physicians to determine the influence of precollege characteristics, college origins, and the academic and social experience of college on the likelihood of becoming a physician. Estimates of a 14-variable causal model indicated that the major direct effects on attainment were attributable to college characteristics and the academic experience of college. Net of other causes, the selectivity/prestige of the undergraduate institution attended, collegiate academic achievement, and majoring in the physical or life sciences each had significant direct effects on becoming a physician. The direct positive influence of college quality, however, was partially counterbalanced by its negative indirect effect. Moreover, the greatest advantage in attending an elite institution accrued to those students with relatively high levels of academic performance. As academic performance declined, so did the positive effect of college quality. The effects of precollege characteristics on becoming a physician were largely indirect, mediated by the student's college experience. Net of other factors, women were no less likely than men to become physicians, but being female had a significant negative indirect effect. Conversely, secondary school achievement did not directly influence attainment but did have a large positive indirect influence.An earlier version of this paper was presented at the annual meeting of the Association for the Study of Higher Education, San Diego, February, 1987.     

Teacher as Researcher,Teacher as Scholar,and Teacher as Leader

ABSTRACT

Too often, because of the static nature of schools and the dominant existence of high-stakes testing, professional learning for teachers is determined by administrators or policy and is facilitated by those who are not part of the school community using prepackaged programs. These initiatives run counter to authentic teacher inquiry where teachers enhance their understanding of students and learning and, ideally, develop new teaching practices (Borko, 2004; Cochran-Smith & Lytle, 1999, 2009; Darling-Hammond, 1997). In this article, we focus on how teachers participating in action research begin to position themselves as teacher leaders.     

Types and Qualities of Knowledge and their Relations to Problem Solving in Physics

Based on empirical findings and theoretical considerations related to the field of expertise research, the importance of “types” and “qualities” of knowledge in relation to problem solving in physics was investigated. The students (N =138) in this study had a level of competence that corresponds to an intensive beginner college course in physics. It was found that conceptual declarative knowledge and problem scheme knowledge are excellent predictors of problem solving performance. However, a detailed analysis shows that the first knowledge type is more typical for low achievers (novices) in physics problem solving whereas the second type is predominately used by high achievers (experts). Regarding types and qualities of knowledge and their relations to problem solving, the results of a multidimensional scaling analysis (MDS) indicate that two dimensions of knowledge can be distinguished. On the extreme limits of the first dimension, which could be named “problem solving relevance vs. structure of discipline”, are the types of knowledge and the qualities of knowledge, respectively. The second dimension of knowledge could be named “single knowledge elements vs. organised knowledge units”. There are types of knowledge as well as qualities of knowledge distributed along this dimension. Consequences of these results for improving physics education are discussed.     

REMEMBERING TELEVISED NEWS:EFFECTS OF VISUAL FORMAT ON INFORMATION GAIN

Nine television news stories were presented to 60 college students under three different visual format treatment conditions: newscaster‐only presentation, newscaster‐plus‐film or newscaster‐plus‐stills. Detailed information gain from the news stories was tested using a 27‐item multiple‐choice questionnaire which was administered immediately after viewing. It was found that overall learning was slightly, though not significantly, poorer from stories accompanied by picture materials than from those presented by the newscaster alone. It is suggested that news editors assumptions about the effects of pictorial material upon news impact may be only partially correct.     

Education and the Contested Meanings of ‘Global Citizenship’

This article examines the oftentaken-for-granted educational policy and curricular discourses of globalization and global citizenship within their larger cultural, political, and economically uneven histories and unequal consequences. Drawing upon evidence from recent scholarship on the implications for classroom pedagogy embodied inefforts to internationalize curricula in the North American university contexts, as well as specific related efforts in one Canadian context, the University of British Columbia,this article unpacks the contested meanings of global citizenship from above and below.The author analyzes three dominant curricular discourses of global citizenship. Far from weakening the Canadian state and building instances of transnational democratic educational communities, these dominant discourses may actually reinforce notions of Canadian gendered and racialized nation-building and nationalism. The article raises questions about what an alternative curricular and educational policy discourse from below premised upon efforts to decolonize curricula might look like. By way of provisional conclusion, the author discusses some promising examples of such an alternative,showing how they depend on seeing the relations between the local and global neither as fixed abstractions nor as a slogan system to be applied in absolutist racial, geographical,national, or culturally essentialist terms.     

Relative contributions of parent substance use and childhood maltreatment to chronic homelessness,depression, and substance abuse problems among homeless women: mediating roles of self-esteem and abuse in adulthood

OBJECTIVE: This study, using latent variable methodology, explores simultaneously the relative effects of childhood abuse and early parental substance abuse on later chronic homelessness, depression, and substance abuse problems in a sample of homeless women. We also examine whether self-esteem and recent violence can serve as mediators between the childhood predictors and the dysfunctional outcomes.METHOD: The sample consists of 581 homeless women residing in shelters or sober living centers in Los Angeles (54% African-American, 23% Latina, 22% White, mean age=33.5 years). Multiple-indicator latent variables served as predictors and outcomes in structural models. Childhood abuse was indicated by sexual, physical, and verbal abuse.RESULTS: Childhood abuse directly predicted later physical abuse, chronic homelessness, depression, and less self-esteem. Parent substance use directly predicted later substance use problems among the women. Recent physical abuse predicted chronic homelessness, depression, and substance use problems. Greater self-esteem predicted less depression and fewer substance use problems. Childhood abuse also had significant indirect effects on depression, chronic homelessness, and drug and alcohol problems mediated through later physical abuse and self-esteem.CONCLUSIONS: Although there was a strong relationship between childhood abuse and parent drug use, childhood abuse was the more pervasive and devastating predictor of dysfunctional outcomes. Childhood abuse predicted a wider range of problems including lower self-esteem, more victimization, more depression, and chronic homelessness, and indirectly predicted drug and alcohol problems. The mediating roles of recent physical abuse and self-esteem suggest salient leverage points for change through empowerment training and self-esteem enhancement in homeless women.     

Engagement in dialogue: tracing our connections or speaking across the space between?

Abstract

In this paper I contrast conceptions of self from two perspectives: an individualistic orientation and a communitarian approach. In doing so, the philosophical justification is Wittgenstein’s idea that individualism is produced and reinforced as a way of being, thinking and interacting in community. With this contextual frame, I argue that we are shaped by the language practices of our community to ascribe meaning and interpret our own relationships with others through our language lexicon and grammar. To illustrate the communitarian perspective I refer to Māori perspectives in which connectedness is axiomatic: in particular the concepts of whanaungatanga and whakapapa, as described by Ka’ai and Metge. On the basis that such concepts are predicated on language use, I suggest that we can learn the grammar of engagement in a discursive context that emphasises connectedness just as easily as in one which is founded on separateness. I argue that interacting with an other is to engage with the ideas, beliefs, and values that shape their language, even as we expose our own. Engaging between individualistic and communitarian understandings is presented as learning to bridge language gaps between different social constructs and understandings of reality.
