An Investigation of Student Roles within Small,Racially Mixed Science Groups: A racial perspective

Achievement disparities among racial groups attest to the elusiveness of the ‘science for all’ goal, an emphasis of reform efforts in the USA. One popular approach to making science accessible to all is group work. The study investigated roles attained by five African American and six European‐American eighth graders working in small, racially mixed groups. What roles did the African‐American and European‐American students attain in the small, racially mixed science groups? Did race‐associated patterns of role attainment exist? If so, what was the nature of the patterns? Roles were derived and patterns examined via the qualitative and quantitative analyses of videotaped group interactions. The findings indicated that European‐Americans attained roles more frequently than their African‐American counterparts of comparable abilities and whiteness operated in the small groups. The findings imply racial inequities in group work and the need for teachers to consider race when employing it.     

Rural health nurses as educators: A problem of marginality

The decision by the Northern Territory Department of Health to employ Aboriginal health workers has supposedly resulted ina shift in emphasis for non Aboriginal rural health nurses from clinical work to education and consultation. This paper examines the gap between the rhetoric and the reality of this claim by applying, with modifications, Burton Clark's (1958) theory of the marginality of adult education to an educational innovation. In 1981 rural health nurses were requested to implement an educational program that included teaching Aboriginal health workers literacy and numeracy along with clinical skills. The results of an evaluation research of this innovation conducted over the period 1982‐3 show that this activity was avoided by nurses because of its marginal status. Those who took up the innovation also risked sharing in this marginality. It is also argued that while Clark's theory is applied to only one case, i.e. the teaching of literacy, it points the way to a formal theory for explaining the difficulties experienced by rural health nurses who wish to take up any formal educational activities on Aboriginal settlements.     

Developing Summarization Skills through the Use of LSA-Based Feedback

This paper describes a series of classroom trials during which we developed Summary Street, an educational software system that uses Latent Semantic Analysis to support writing and revision activities. Summary Street provides various kinds of feedback, primarily about whether a student summary adequately covers important source content and fulfills other requirements, such as length. The feedback allows students to engage in extensive, independent practice in writing and revising without placing excessive demands on teachers for feedback. We first discuss the underlying educational rationale, then present some results of the trials conducted with the system. We describe the collaborative process among researchers and teachers which enabled the development of a viable and supportive educational tool and its integration into classroom instruction.

Though, in theory, black students may have access to equal educational opportunity by occupying the same classroom space as their peers, they do not necessarily enjoy the same quality of experience. This inequality results from the race-related beliefs and norms and white privilege embedded in United States society. This study deconstructed one white teacher's practices with respect to the literature on effective teachers of black students and caring. The idea of culturally relevant caring emerged and was explored in relation to the teacher's actions that enabled black students to access the quality of experience enjoyed by their white counterparts.     

Place conditioning with d-amphetamine: The effect of the CS-UCS interval and evidence of a place avoidance

In Experiment 1, a dose-response study of place conditioning with amphetamine was conducted. Male Sprague-Dawley rats receiving 0.0, 0.05, 0.1, 0.5, 2.0, 5.0, 7.5, or 10.0 mg/kg of d-amphetamine underwent 104-day cycles of place conditioning. On alternate days, each rat was injected with its designated dose of amphetamine while confined to its originally nonpreferred end of a three-compartment, straight alley box. On intervening days, each rat was injected with saline while confined to its originally preferred compartment. Following each 4-day cycle, a choice test was administered in which each rat was allowed 20 min of access to the entire alley box. Doses of amphetamine (≥0.5 mg/kg) induced a significant avoidance of the compartment in which amphetamine had been administered. In Experiment 2, animals received 0.0, 0.5, 2.0, or 5.0 mg/kg of amphetamine and underwent place conditioning procedures identical to those for the animals in Experiment 1. Unlike in Experiment 1, the animals were given a single choice test following 104-day place conditioning cycles. All groups that received amphetamine exbibited-a-eonditioned place avoidance. In Experiment 3, the effect of various CS-UCS intervals on place conditioning with 2.0 mg/kg of amphetamine was examined. Animals that received amphetamine immediately following their removal from the chamber exhibited a conditioned place avoidance.     

Power Drawing

Power Drawing is the education programme of the Campaign for Drawing initiated by the Guild of St George. Primarily a research and development programme, it focuses on drawing in schools and other educational settings and investigates how the use of drawing can help children and young people learn in a variety of subjects. The intention is to develop a range of strategies, methods and techniques to support learning through drawing. This paper explains the ideas underpinning the programme, how it is organised and the research methods used. It describes and reflects on the experience of the first year of the action research, and comments on some of the satisfactions and tensions that have emerged. It outlines how these will influence further development.     

How communication context impacts judgments of a potential peer mentor

Disclosure is a critical element of interpersonal relationships and individuals are often evaluated on what they share with others, whether in personal, professional, or learning contexts. Technology now allows for many different outlets for communicating with other people. We used experimental methods to explore the impact of communication medium (i.e. print diary, online diary, blog, or email) on psychosocial perceptions of a potential peer mentor. Female participants gave more positive mentor ratings on likeability, likeliness to disclose to the mentor, and perceived closeness than did males, but not on judgments of the mentor’s privacy. Participants judged the mentor to be more private when they viewed the print diary than in the online conditions and when reading the online diary than the blog (the least private condition). We also found that women were more likely to reciprocate disclosure when they viewed disclosures in the print condition than in the blog.
