The "Socialization" and Enculturation of Ecologists in Formal and Informal Settings
G. Michael Bowen
University of Victoria
Ethnographic studies of scientists and science rarely
focus on either the enculturation of scientists-in-training
or field scientists (particularly biologists and their
"small science" work) but instead focus on experienced
scientists who conduct research in laboratory environments.
This is relevant to the learning of ecology for the locales
where the formal learning about ecology occurs is unlike
where ecology research is conducted--laboratory sciences,
such as physics and chemistry, learn about the research
practices of their discipline in settings similar to the
environments in which such research is actually conducted.
Drawing on three years of ethnographic work examining the
enculturation of ecologists, this paper examines the formal
and informal settings in which ecologists learn (about)
their discipline and reports on the contributions that each
setting makes to learning about the conduct of field
research. Often ignored informal aspects of learning about
the conduct of ecology research, such as story telling in
"leisure" settings, are revealed as being important to
becoming enculturated into ecological field research

On-line web-based technologies provide students with the opportunity to complete assessment instruments from personal computers with internet access. The purpose of this study was to examine the differences in paper-based and web-based administrations of a commonly used assessment instrument, the Force Concept Inventory (FCI). Results demonstrated no appreciable difference on FCI scores or FCI items based on the type of administration. A 4 way ANOVA (N = 376) demonstrated expected differences in FCI scores due to different sections of the same sections, different courses and gender. However, none of these differences was influenced by the type of test administration. Similarly, FCI student scores were comparable with respect to both test reliability and predictive validity. For individual FCI items, paper-based and web-based comparisons were made by examining potential differences in item means and by examining potential differences in response patterns. Chi Squares demonstrated no differences in response patterns and t Tests demonstrated no differences in item means between paper-based and web-based administrations. In summary, the web-based administration of the Force Concept Inventory appears to be as efficacious as the paper-based administration.
The Tension Between HyperText Environments and Science Learning
byGregory R. MacKinnon

Computer technology has afforded opportunities to design science curriculum experiences that capitalize on hypertext environments. Though these settings may provide students with flexibility as they explore science the question remains, does science inherently favor sequential approaches to curriculum? This paper addresses the tension this creates using as an example an action research study of a high school acid-base chemistry unit.

The Effects of English Language Proficiency and Scientific Reasoning Skills on the Acquisition of Science Content Knowledge by Hispanic English Language Learners and Native English Language Speaking Students
byHector N. Torres
University of Massachusetts, Lowell
andDana L. Zeidler
University of South Florida
The purpose of this paper was to examine the effects of English language proficiency and levels of reasoning skills of Hispanic English language learners and native English language speaking students on their acquisition of science content knowledge as measured by a state-wide standardized science test.
The authors suggest that the levels of English language proficiency appear to influence the acquisition of science content knowledge of Hispanic English language learners in the study. The results also suggest that with regards to reasoning skills, students that showed high levels or reflective reasoning skills for the most part performed better on the statewide-standardized science test than students with intuitive or transitional reasoning skills.
Furthermore, the findings of the paper imply that high order English language proficiency combined with high levels of reasoning skills enhances students' abilities to learn science content subject matter.
