Navigating barriers: A qualitative examination of the under-representation of Black females as head coaches in collegiate basketball

Although sport management researchers have produced findings with regard to diversity in the leadership positions of college athletics, this examination has focused separately on gender (Inglis et al., 1996, Inglis et al., 2000; Inglis, Danylchuk, & Pastore, 2000; Knoppers et al., 1991, National Collegiate Athletic Association, 2009a, Sartore and Cunningham, 2007) or race (Cunningham and Sagas, 2004a, Cunningham and Sagas, 2004b, Cunningham et al., 2001, Cunningham et al., 2006). The current study, framed by intersectionality, identifies barriers contributing to the under-representation of Black women in head coaching jobs in Division I women's basketball in the United States. The assistant coaches cited access discrimination, lack of support, and prevalent stereotypes as barriers. In negotiating these barriers, the women discussed the importance of networking, mentoring and presenting “a proper image” for big-time athletics. To eradicate these barriers, the women recommended expanding job pools; more mentoring by athletic department personnel; and more development programs offered for young Black females.

Evolution and the nature of science: On the historical discord and its implications for education

Research in the teaching and learning of evolutionary biology has revealed persistent difficulties in student understanding of fundamental Darwinian concepts. These difficulties may be traced, in part, to science instruction that is based on philosophical conceptions of science that are no longer viewed as adequately characterizing the diverse nature of scientific practice, especially in evolutionary biology. This mismatch between evolution as practiced and the nature of science as perceived by researchers and educators has a long history extending back to the publication of Darwin's theory of natural selection. An examination of how this theory was received by the scientific community of the time may provide insight into some of the difficulties that students have today in learning these important biological concepts. The primary difficulties center around issues of metaphysics and scientific method, aspects of the nature of science too often ignored in science education. Our intent is not to offer a specific course of action to remedy the problems educators currently face, but rather to suggest an alternative path one might take to eventually reach a solution. That path, we argue, should include the use of broader models of science that incorporate these elements of scientific practice to structure teaching and education research in evolution. © 1998 John Wiley & Sons, Inc.

Parental assessment of peer play: Development and validation of the parent version of the Penn Interactive Peer Play Scale

The purpose of this investigation was to evaluate the construct validity of the parent version of the Penn Interactive Peer Play Scale (PIPPS) and to compare it with the teacher version. PIPPS were collected on 297 urban Head Start children. The Parent PIPPS replicated the three-factor solution found with the teacher version, supporting the following constructs of peer play: Play Interaction, Play Disruption, and Play Disconnection. Factor matching and canonical correlational analyses examining the relationship between the parent and teacher versions of the PIPPS revealed significant one-to-one matches between hypothesized like factors. Additionally, analyses of overlapping variance between versions indicated a significant degree of overlap. Implications of the findings for involvement of parents in the assessment process and research on the continuity and discontinuity between home and school environments for low-income, urban children were discussed.

A Comparative Study or Western and Japanese Practices Geared Towards Improved Learning and New Product Performance

Increasingly, the long‐term success of a company resides in its ability to develop and market successful new products in a cost‐and time‐effective manner. In general, Japanese companies have outperformed their Western counterparts in bringing new products to market over the last 10 to 20 years. This has given them a substantial advantage in long‐term economic development. The authors hypothesize that the differences between the dominant models of corporate culture in Japan and the U.S. account for the Japanese advantage. In comparison to U.S. companies, Japanese companies tend to emphasize long‐term leadership, decentralized decision making, a flatter work structure using cross‐functional work teams, and rewarding teams for the ability to learn from mistakes. As a result of these differences, Western companies are more likely to utilize “single, loop” learning, where new products are developed using established (and unquestioned) procedures. Conversely, Japanese companies rely on “double‐loop” or “deutero” learning styles, which encourage employees to leverage their past experiences when proposing new product innovations. The authors conclude by outlining a research program for testing their as‐gumptions about the relations among nationality, corporate culture, learning styles, and new product success.     

Dynamic mental models in learning science: The importance of constructing derivational linkages among models

We present a theory of learning in science based on students deriving conceptual linkages among multiple models which represent physical phenomena at different levels of abstraction. The models vary in the primitive objects and interactions they incorporate and in the reasoning processes that are used in running them. Students derive linkages among models by running a model (embodied in an interactive computer simulation) and reflecting on its emergent behaviors. The emergent properties they identify in turn become the primitive elements of the more abstract, derived model. We describe and illustrate derivational links among three models for basic electricity: a particle model, an aggregate model, and an algebraic model. We then present results of an instructional experiment in which we compared high school students who were exposed to these model derivations with those who were not. In all other respects, both groups of students received identical instruction. The results demonstrate the importance of enabling students to construct derivational linkages among models, both with respect to their understanding of circuit theory and their ability to solve qualitative and quantitative circuit problems. © 1999 John Wiley & Sons, Inc.

A Proposal for State,Income-Targeted,Preschool Vouchers

This article proposes that states create low-income targeted voucher programs for 3- and/or 4-year-olds. The basis for this proposal is considerable research demonstrating long-term effects for a number of random assignment and quasi-experimental preschool programs. Benefit–costs rates of return for these programs are between $2 and $16 for every dollar invested. These results are also consistent with developmental and neuro-biological studies supporting early childhood interventions. Other research shows that low-income students are less likely to be in preschool, and if they are, they are more likely to receive low-quality services. Taken together, and to control costs, I propose an income-targeted program. I argue for vouchers based on improved equal opportunity and higher efficiency in the delivery of preschool services. Design details are generally to be the province of state decision makers. My one caveat is that it seems to make sense to require programs, at least for 4-year-olds, to be center based.
