Two representations of the research process: The preparing,searching, and using (PSU) and the beginning,acting and telling (BAT) models

Two representations of a three-stage diagrammatic model that holistically depicts the research process are presented. The representations incorporate elements culled from existing information-seeking behavior and information literacy instruction research, as well as evidence gathered from a study of third grade elementary school students, as they worked to fulfill a class project's requirements. Both representations are content independent, attribute equal importance to each of the three stages, and target the K-12 educational environment. The full representation, the preparing, searching, using (PSU) model, is intended for use by instructors and more advanced students. The model identifies elements inherent within the three stages of the research process including actions, affective behaviors, impact factors, learning, and reflection. The simpler representation, the beginning, acting, telling (BAT) model, which is embedded into the PSU, presents only the three main stages and the actions associated with those stages using a familiar graphic (a bat) and a mnemonic device to visually present the basic elements of the research process to younger elementary school students. The PSU model is designed to identify and address the unique information behaviors of students (affective, cognitive, and physical) and factors that may impact the research process. As a result, the representations can be used by educators, including information professionals and teachers, to inform instruction, such as lesson planning, development of assignments, resource location and evaluation, and the use of information, to fully exploit all aspects of the research process. The PSU model can also be used to teach more sophisticated concepts to older students by introducing more complex features gradually to the BAT model.     

Effects of caffeine chewing gum on race performance and physiology in male and female cyclists

This investigation reports the effects of chewing caffeinated gum on race performance with trained cyclists. Twenty competitive cyclists completed two 30-km time trials that included a maximal effort 0.2-km sprint each 10-km. Caffeine (~3–4 mg · kg^?1) or placebo was administered double-blind via chewing gum at the 10-km point following completion of the first sprint. Measures of power output, oxygen uptake, heart rate, lactate and perceived exertion were taken at set intervals during the time trial. Results indicated no substantial differences in any measured variables between caffeine and placebo conditions during the first 20-km of the time trial. Caffeine gum did however lead to substantial enhancements (mean ± 90% confidence limits (CLs)) in mean power during the final 10-km (3.8% ± 2.3%), and sprint power at 30-km (4.0% ± 3.6%). The increases in performance over the final 10-km were associated with small increases in heart rate and blood lactate (effect size of 0.24 and 0.28, respectively). There were large inter-individual variations in the response to caffeine, and apparent gender related differences in sprint performance. Chewing caffeine gum improves mean and sprint performance power in the final 10-km of a 30-km time trial in male and female cyclists most likely through an increase in nervous system activation.     

Wrestling Whiteness: Three Stages of Shifting Multicultural Perspectives among White Pre-service Teachers

Pedagogical progress in the field of multicultural education moves at a snail's pace due to pre-service teachers' level of acceptance of multiculturalism and its tenets. Teacher candidates and seasoned teachers are simply unconscious and apathetic about matters of diversity. Pre-service teachers, primarily White and middle class, are mandated to take multicultural courses and grapple with recognizing their own cultural beings and the cultural realities of others. While student populations grow more diverse, the pre-service teacher population is becoming more homogenous. A major obstacle in teacher preparation programs arising from this mismatch of teacher and student cultures is the ability to facilitate a critical consciousness. This includes the ability to analyze the world and employ equity pedagogy in pre-service teachers who are resistant to diversity issues.

Pre- and post-course surveys, in open-ended and anonymous narrative form, were administered to White pre-service teachers (= 94), and this article is divided into two sections based on the results. First, I outline the three shifting perspectives that were identified during a semester-long course with White and middle class pre-service students, and then connect these perspectives to existing research on racial identity ego, theorizing whiteness, and curriculum integration. This new theoretical model addresses equity pedagogy and is framed within whiteness and consciousness studies and may serve as a reflective tool for educators to self-evaluate their pedagogical proclivities. Second, the implications of this informal action research project for White pre-service educators and research in theorizing whiteness are developed.     

Using Photographs to Assess Equity Climate: A Taxonomy

Our challenge as teachers and as human beings is to begin the process of "changing our voices," facing who we are and what that means in a society based on power and oppression. We must learn to listen to others, so we can speak together with voices both united and unique. The journey described is personal, yet it is also generalizable. Changing one's voice may be the only real way in which a teacher can be a model of diversity and multiculturalism. If as a teacher I do nothing to change my own voice, I have accomplished little in terms of effective teaching. My attitudes, behaviors, words should reflect and embody humanity, not just those who "look" like me or are thought of as more capable learners. I must challenge my students' thinking in terms of diversity and multicultural issues and push them to think of the "other."
