This paper takes a critically reflective look at field research done in the early career of an academic and in so doing uncovers the dilemmas of a novice researcher that are rarely acknowledged in texts that address qualitative methods. It addresses issues of power in research associations surrounding different paradigms and the ways in which the study changed as boundaries were increasingly blurred. It also examines lessons learned about interviewing and challenges the notion of an un‐analytical informant as being necessary to quality and depth of data.  相似文献

Librarians offer a unique perspective on e-books: on one hand they collect these resources and train users as part of their jobs, while on the other hand, they may be users of e-books themselves. With recent increases in research expectations for Canadian academic librarians, this study aimed to discover: when librarians do research, do they use e-books and how often are they using them? This study examines the results of a survey of 392 academic librarians from across Canada. The survey generated data on librarians' use of, and attitudes towards, e-books. While a number of studies examine the use and opinions of e-books among other user groups, this study examines how librarians search for or use e-books differently than other user groups. Results will help librarians to improve their liaison work and make more informed collection development decisions at their own institutions.  相似文献

Relying on cultural transmission, social identity and self-categorization theories, this study uses an innovative two-part photo-pasting and survey method to investigate quantitatively and qualitatively non-fans’, fans’ and players’ assumptions about what positions black and white players should occupy in American football. Both white and black players and fans showed evidence of being cultural transmitters of racial ideologies associated with the quarterback position in American football. Overall, the respondent choices for quarterback diverged significantly from equality but not significantly from the reality of the National Football League. Players and fan and non-fan participants alike showed evidence of being cultural consumers and transmitters of racial ideologies associated with the quarterback position. Narrative reasons for player choices aligned with past literature about racial stereotypes. On most measures, the findings did not differ greatly among the institutions from which study participants were drawn, their diversity in geography, racial composition, ideology, athletic division and public–private status notwithstanding.  相似文献

Three hundred and ninety‐nine Grade 4 Brisbane children were given a battery o1 general ability and achievement tests. Means and standard deviations allowed construction of 15‐point scales for a Queensland Grade 4. A correlation matrix included indices concerning sub‐tests of general ability and achievement tests. Comparisons with original A.C.E.R. co‐efficients were made. The matrix was factor sub‐tests of general ability and achievement tests. Comparisons with analysed and rotated, three factors emerging ‐‐ verbal, performance and computational. A canonical correlation was performed and three significant elements emerged ‐‐ a verbal, a computational (or integrative or automatic sequential) and a problem‐solving element.  相似文献

We have developed experiments and materials to model human genetics using rapid cycling Brassica rapa, also known as Fast Plants. Because of their self-incompatibility for pollination and the genetic diversity within strains, B. rapa can serve as a relevant model for human genetics in teaching laboratory experiments. The experiment presented here is a paternity exclusion project in which a child is born with a known mother but two possible alleged fathers. Students use DNA markers (microsatellites) to perform paternity exclusion on these subjects. Realistic DNA marker analysis can be challenging to implement within the limitations of an instructional lab, but we have optimized the experimental methods to work in a teaching lab environment and to maximize the “hands-on” experience for the students. The genetic individuality of each B. rapa plant, revealed by analysis of polymorphic microsatellite markers, means that each time students perform this project, they obtain unique results that foster independent thinking in the process of data interpretation.  相似文献

The unskilled and unaware effect refers to the finding that individuals who are less knowledgeable or less skilled in a domain are relatively less able to evaluate their level of skill or effectively utilise feedback relative to individuals who are more skilled. Studies finding deaf students less accurate than hearing students in estimating their English vocabulary knowledge and in judging how much they are learning from material presented via sign language have attributed those results to the unskilled and unaware effect, citing the lack of language fluencies frequently demonstrated among deaf learners. The present study addressed the issue more directly by comparing both deaf and hearing individuals who were more and less skilled in four domains, three linguistic and one nonlinguistic. Results indicated that even individuals who are unskilled in a nonlinguistic domain can evaluate their performance when they are aware of what skilled performance would look like, and that unskilled and unaware effects can be influenced by individuals’ desires to be skilled.  相似文献
