Racial Inequality in Critical Thinking Skills: The Role of Academic and Diversity Experiences

While racial inequalities in college entry and completion are well documented, much less is known about racial disparities in the development of general collegiate skills, such as critical thinking. Using data from the Wabash National Study of Liberal Arts Education, we find substantial inequality in the development of critical thinking skills over four years of college between African American and White students. The results indicate that these inequities are not related to students’ academic experiences in college but are substantially related to their experiences with diversity. These findings have important implications for understanding racial inequality in higher education and considering strategies for addressing observed disparities.     

Student evaluation of audience response technology in large lecture classes

In the past few years, audience response technology (ART) has been widely adopted on college campuses, and is especially popular among instructors of large lecture classes. Claims regarding ART’s benefits to students have received only limited empirical evaluation, and prior studies exhibit methodological limitations. The current study provides a multi-dimensional evaluation, utilizing a newly-developed measure, the Audience Response Technology Questionnaire (ART-Q). Data were provided at three points during a semester by undergraduate students (n = 854) who used ART in three large lecture university courses. Results indicate moderately positive evaluations of ART on some dimensions (e.g., ease of use, impact on attendance), with less positive evaluations on others (e.g., influence on preparation for class). These evaluations showed some variability across time of semester and course, but were not substantially affected by gender, ethnicity, or year in school. Findings are discussed with respect to the need for future research on instructors’ techniques for using ART and their influence on student perceptions and outcomes.

Primary teachers conducting inquiry projects: effects on attitudes towards teaching science and conducting inquiry

ABSTRACT

This study used an experimental, pretest-posttest control group design to investigate whether participation in a large-scale inquiry project would improve primary teachers’ attitudes towards teaching science and towards conducting inquiry. The inquiry project positively affected several elements of teachers’ attitudes. Teachers felt less anxious about teaching science and felt less dependent on contextual factors compared to the control group. With regard to attitude towards conducting inquiry, teachers felt less anxious and more able to conduct an inquiry project. There were no effects on other attitude components, such as self-efficacy beliefs or relevance beliefs, or on self-reported science teaching behaviour. These results indicate that practitioner research may have a partially positive effect on teachers’ attitudes, but that it may not be sufficient to fully change primary teachers’ attitudes and their actual science teaching behaviour. In comparison, a previous study showed that attitude-focused professional development in science education has a more profound impact on primary teachers’ attitudes and science teaching behaviour. In our view, future interventions aiming to stimulate science teaching should combine both approaches, an explicit focus on attitude change together with familiarisation with inquiry, in order to improve primary teachers’ attitudes and classroom practices.     

An econometric estimate of the demand for MBA enrollment

A demand equation for MBA enrollment was estimated to test the theory of human capital as an explanation of enrollment decisions in higher education. Three of four variables associated with a human capital interpretation were found to be significant. The functional form of the demand equation (log-reciprocal) was of importance in establishing these results. Although the failure of the interest rate to be significant might suggest imperfections in access to capital for potential students, we could not find support for the alternative view that students relied on subsidization by family. Several elasticities proved to be large enough to imply that feasible changes in the rates of change of underlying economic variables could produce noticeable changes in MBA enrollment.     

Toward an epistemology of a brown body

In its current emphasis on all that is analytic and cognitive, the absence and elusiveness of the body in educational research defines and delineates any consideration of how new identities, particularly the emerging identities of Latina/o lesbian and gay youth, are being invented within a contestation of dominant discourses of race, class, gender, and sexuality. In a reevaluation of the writings of Chicana theorists Cherrie Moraga and Gloria Anzaldua, this paper locates the brown body as central in an ongoing practice of negotiation in which multiple, often opposing, ideas and ways of being are addressed, appropriated, and negotiated. The brown body, with its multiple and often oppositional intersections of sociopolitical locations, must be acknowledged in its centrality in creating new knowledges. For the educational researcher, understanding the brown body and the regulation of its movements is fundamental in the reclamation of narrative and the development of radical projects of transformation and liberation.     

Laboratory materials: Affordances or constraints?

Laboratory instruction is critical to the understanding of biology and is a central piece of biological sciences instruction. Although much investigation has focused on the content of biology laboratory exercises, we contend that understanding the extent to which the laboratory materials can aid or limit experimental investigation is of equal importance. In this study, therefore, we investigate the role of timing and availability of laboratory equipment in the context of two different laboratory exercises. We use both case study and an experimental approach to investigate how laboratory materials guide the planning, context, creativity, and timing of ideas shared among students. Our data support the notion that providing students with laboratory equipment before students plan and consider different experimental approaches can constrain students' ideas and encourage tool‐focused solutions to experimental design tasks. © 2011 Wiley Periodicals, Inc.

Factors related to university presidents' pay: An examination of private colleges and universities

In this research, we used institutionalcharacteristics and market-related factors to predictuniversity president's pay, benefits, and totalcompensation at 190 private colleges and universities. Results showed that university CEOs' pay was relatedto the expenditures, type of institution, theexistence of professional schools, and academicreputation ranking, while their benefits package wasrelated to the expenditure, type of institution,reputation ranking, and undergraduate student'stuition. CEOs' total compensation (pay and benefitscombined) was related to the expenditures, type ofinstitution, reputation ranking, and tuition. Resultsof this study support the notion that agency theorycan be used to provide a theoretical framework topredict university CEOs' pay, benefits, and totalcompensation.
