Modifying Knowledge,Emotions, and Attitudes Regarding Genetically Modified Foods

The purpose of this study was to explore whether conceptual change predicted emotional and attitudinal change while learning about genetically modified foods (GMFs). Participants were 322 college students; half read a refutation text designed to shift conceptual knowledge, emotions, and attitudes, while the other half served as a control group. The results suggest that the refutation text effectively facilitated change in conceptual knowledge, emotions, and attitudes. The hypothesized relationship among the variables was explored using structural equation modeling. The analysis showed that when participants experienced knowledge change toward more scientifically accepted conceptions of GMFs, their emotions became more positive and less negative, which predicted a subsequent shift toward more-positive attitudes. The results suggest that change in emotions mediates the relationship between conceptual and attitudinal change. Several theoretical and practical implications are discussed including the impact that these findings may have on science education.     

Selection bias in college admissions test scores

Data from college admissions tests can provide a valuable measure of student achievement, but the non-representativeness of test-takers is an important concern. We examine selectivity bias in both state-level and school-level SAT and ACT averages. The degree of selectivity may differ importantly across and within schools, and across and within states. To identify within-state selectivity, we use a control function approach that conditions on scores from a representative test. Estimates indicate strong selectivity of test-takers in “ACT states,” where most college-bound students take the ACT, and much less selectivity in SAT states. To identify within- and between-school selectivity, we take advantage of a policy reform in Illinois that made taking the ACT a graduation requirement. Estimates based on this policy change indicate substantial positive selection into test participation both across and within schools. Despite this, school-level averages of observed scores are extremely highly correlated with average latent scores, as across-school variation in sample selectivity is small relative to the underlying signal. As a result, in most contexts the use of observed school mean test scores in place of latent means understates the degree of between-school variation in achievement but is otherwise unlikely to lead to misleading conclusions.     

Traversing the Challenges of Conducting Research with Young, Immigrant Children: The Case of Korean Children

Based on a qualitative study on young Korean immigrant children’s interpretation of American popular culture, this paper reflects on the researchers’ role by examining the research challenges faced. Prior to discussing the research obstacles in conducting the study, we begin with briefly describing its methodology and design. Next, we discuss the various obstacles we encountered when conducting our study and howwe attempted to overcome these dilemmas by discussing two major struggles during the research process: a) the relationships between the researchers and our young participants, and b) the cultural sensitivity that was needed in initially gaining permission from and working with the parents of our informants. It then illuminates how the researchers attempted to cope with such difficulties by rethinking a researchers’s role emphasizing the importance of cultural context in research. Finally, the paper provides some discussions and implications based on our research experiences.     

The ‘subject of ethics’ and educational research OR Ethics or politics? Yes please!

This paper outlines a theoretical context for research into ‘the subject of ethics’ in terms of how students come to see themselves as self-reflective actors. I maintain that the ‘subject of ethics’, or ethical subjectivity, has been overlooked as a necessary aspect of creating politically transformative spaces in education. At the heart of egalitarian politics lies a fundamental tension between the equality of voices (or ways of being) and the notion that one way of being or one voice may be deemed more legitimate than another; which in turn puts the equality of beings into question. Building from Michel Foucault’s work regarding ethics and subjectivity, I suggest that a ‘subject of ethics’ can be viewed, in part, as a series of relations of self that form the horizon upon which a subject comes to work on themselves relative to moral codes and power relations. Ethical relations of self can be a useful concept for those interested in educational research that furthers social and ecological justice. In the conclusion of this paper I also discuss the limitations of locating ethics entirely within a constituted human subject.
