Native Americans and the U.S. Census: A brief historical survey

This article traces the history of the enumeration of American Indians by the U.S. Census Bureau and its predecessors. It considers the social and political background of the census and the reasons that Native Americans were not counted by the census until 1890. It also examines the changes in the enumeration and definition of Native Americans—key concepts needed to provide effective reference service for users of Census Bureau data.     

Are low achievers disliked in a cooperative situation? A test of rival theories in a mixed ethnic situation

The effect of cooperative and individualistic learning experiences within which majority students worked with lower-achieving minority peers were compared. A number of theories predict that when white students collaborate with lower-achieving minority students prejudice and rejection will increase. These theories were tested against a counter position that working collaboratively promotes liking regardless of differences in achievement. Forty-eight students (20 minority and 28 white) were assigned to conditions on a stratified random basis controlling for ethnic membership, sex, social class, and ability level. They participated in the study for 55 min a day for 15 instructional days. The results indicate that cooperative learning experiences, compared with individualistic ones, promoted higher achievement for minority students, more cross-ethnic interaction aimed at supporting and regulating efforts to learn and ensuring the active involvement of all students, and greater cross-ethnic interpersonal attraction. The results do not support the theories that posit equal achievement levels are necessary for successful integration and do support the position that cooperative experiences result in liking regardless of the ethnic membership or achievement level of collaborators.     

Building a bioinformatics community of practice through library education programs

This paper addresses the following questions:What makes the community of practice concept an intriguing framework for developing library services for bioinformatics? What is the campus context and setting? What has been the Health Sciences Library's role in bioinformatics at the University of North Carolina (UNC) Chapel Hill? What are the Health Sciences Library's goals? What services are currently offered? How will these services be evaluated and developed? How can libraries demonstrate their value? Providing library services for an emerging community such as bioinformatics and computational biology presents special challenges for libraries including understanding needs, defining and communicating the library's role, building relationships within the community, preparing staff, and securing funding. Like many academic health sciences libraries, the University of North Carolina (UNC) at Chapel Hill Health Sciences Library is addressing these challenges in the context of its overall mission and goals.     

Designing spatial visual tasks for research: the case of the filling task

This article focuses on the development and problematization of a task designed to foster spatial visual sense in prospective and practicing elementary and middle school teachers. We describe and analyse the cyclical stages of developing, testing, and modifying several “task drafts” related to ideas around dilation and proportion. Challenged by participant non-actions and non-responses, we as task designers identified and anticipated sources of difficulties, which motivated repeated modification of the task to further the intended learning goals. The task in its present form incorporates numerous considerations including choices around materials, wording of questions and prompts, and sequencing of experiences. It also reflects our enriched understanding of exploration strategies and the roles of manipulatives and technology in spatial visual tasks designed for adult learners.
