Challenging Thoughts,Changing Minds: Preservice Teachers' Reflections on Their Experience Working in an Alternative School Setting     

Brooke Blevins  Brandon Moore  Cameron Dexter Torti 《The Teacher Educator》2017,52(4):326-345

This study was designed to use critical reflective journaling practices to explore the experiences of preservice teachers working in a juvenile justice education program called the Reach Academy. Using a qualitative case study design, the researchers explored how 48 preservice teachers utilized critical reflective journaling to examine their own identities in relation to working in this unique school setting. Three major themes emerged from the reflective journal and interview data: (a) participants preconceived notions were challenged based on their positive interactions with Reach students, (b) preservice participants engaged in critical observation of the Reach Academy teachers and their interactions with students, and (c) participants' focus shifted from themselves to their students' needs. Findings suggest that preservice teachers reflective journaling process facilitated their ability to examine and reconsider their preconceived notions about working with students at the Reach Academy and in other diverse schooling settings.  相似文献   

Teaching cause-effect text structure through social studies content to at-risk second graders     

Williams JP  Nubla-Kung AM  Pollini S  Stafford KB  Garcia A  Snyder AE 《Journal of learning disabilities》2007,40(2):111-120

This study evaluated the effectiveness of a comprehension program integrated with social studies instruction designed for at-risk second graders. The program included instruction in cause-effect text structure, emphasizing clue words, generic questions, graphic organizers, and the close analysis of specially constructed cause-effect target paragraphs. This program was compared (a) to a content-only program that focused only on social studies and did not include text structure instruction and (b) to a no-instruction control. Fifteen classroom teachers, randomly assigned to treatment, provided the instruction. The program improved the comprehension of instructional cause-effect texts, and there were transfer effects on some comprehension measures. The performance of the 2 instructed groups did not differ on any of the content measures, indicating that such integrated instruction can be accomplished without a loss in the amount of content acquired. This study supports our previous findings on the effectiveness of explicit instruction at the primary-grade level.  相似文献   

Genome Consortium for Active Teaching: meeting the goals of BIO2010   总被引：2，自引：2，他引：0

The Genome Consortium for Active Teaching (GCAT) facilitates the use of modern genomics methods in undergraduate education. Initially focused on microarray technology, but with an eye toward diversification, GCAT is a community working to improve the education of tomorrow's life science professionals. GCAT participants have access to affordable microarrays, microarray scanners, free software for data analysis, and faculty workshops. Microarrays provided by GCAT have been used by 141 faculty on 134 campuses, including 21 faculty that serve large numbers of underrepresented minority students. An estimated 9480 undergraduates a year will have access to microarrays by 2009 as a direct result of GCAT faculty workshops. Gains for students include significantly improved comprehension of topics in functional genomics and increased interest in research. Faculty reported improved access to new technology and gains in understanding thanks to their involvement with GCAT. GCAT's network of supportive colleagues encourages faculty to explore genomics through student research and to learn a new and complex method with their undergraduates. GCAT is meeting important goals of BIO2010 by making research methods accessible to undergraduates, training faculty in genomics and bioinformatics, integrating mathematics into the biology curriculum, and increasing participation by underrepresented minority students.  相似文献   

The effects of different doses of caffeine on endurance cycling time trial performance     

Desbrow B  Biddulph C  Devlin B  Grant GD  Anoopkumar-Dukie S  Leveritt MD 《Journal of sports sciences》2012,30(2):115-120

This study investigated the effects of two different doses of caffeine on endurance cycle time trial performance in male athletes. Using a randomised, placebo-controlled, double-blind crossover study design, sixteen well-trained and familiarised male cyclists (Mean ± s: Age = 32.6 ± 8.3 years; Body mass = 78.5 ± 6.0 kg; Height = 180.9 ± 5.5 cm VO2(peak) = 60.4 ± 4.1 ml x kg(-1) x min(-1)) completed three experimental trials, following training and dietary standardisation. Participants ingested either a placebo, or 3 or 6 mg x kg(-1) body mass of caffeine 90 min prior to completing a set amount of work equivalent to 75% of peak sustainable power output for 60 min. Exercise performance was significantly (P < 0.05) improved with both caffeine treatments as compared to placebo (4.2% with 3 mg x kg(-1) body mass and 2.9% with 6 mg x kg(-1) body mass). The difference between the two caffeine doses was not statistically significant (P = 0.24). Caffeine ingestion at either dose resulted in significantly higher heart rate values than the placebo conditions (P < 0.05), but no statistically significant treatment effects in ratings of perceived exertion (RPE) were observed (P = 0.39). A caffeine dose of 3 mg x kg(-1) body mass appears to improve cycling performance in well-trained and familiarised athletes. Doubling the dose to 6 mg x kg(-1) body mass does not confer any additional improvements in performance.  相似文献   

Caffeine withdrawal and high-intensity endurance cycling performance     

Irwin C  Desbrow B  Ellis A  O'Keeffe B  Grant G  Leveritt M 《Journal of sports sciences》2011,29(5):509-515

In this study, we investigated the impact of a controlled 4-day caffeine withdrawal period on the effect of an acute caffeine dose on endurance exercise performance. Twelve well-trained and familiarized male cyclists, who were caffeine consumers (from coffee and a range of other sources), were recruited for the study. A double-blind placebo-controlled cross-over design was employed, involving four experimental trials. Participants abstained from dietary caffeine sources for 4 days before the trials and ingested capsules (one in the morning and one in the afternoon) containing either placebo or caffeine (1.5 mg · kg(-1) body weight · day(-1)). On day 5, capsules containing placebo or caffeine (3 mg · kg(-1) body weight) were ingested 90 min before completing a time trial, equivalent to one hour of cycling at 75% peak sustainable power output. Hence the study was designed to incorporate placebo-placebo, placebo-caffeine, caffeine-placebo, and caffeine-caffeine conditions. Performance time was significantly improved after acute caffeine ingestion by 1:49 ± 1:41 min (3.0%, P = 0.021) following a withdrawal period (placebo-placebo vs. placebo-caffeine), and by 2:07 ± 1:28 min (3.6%, P = 0.002) following the non-withdrawal period (caffeine-placebo vs. caffeine-caffeine). No significant difference was detected between the two acute caffeine trials (placebo-caffeine vs. caffeine-caffeine). Average heart rate throughout exercise was significantly higher following acute caffeine administration compared with placebo. No differences were observed in ratings of perceived exertion between trials. A 3 mg · kg(-1) dose of caffeine significantly improves exercise performance irrespective of whether a 4-day withdrawal period is imposed on habitual caffeine users.  相似文献

The analytical lens: developing undergraduate students’ critical dispositions in undergraduate EAP writing courses     

Mark Brooke  Laetitia Monbec  Namala Tilakaratna 《Teaching in Higher Education》2019,24(3):428-443

ABSTRACT

This paper comprises findings from three parallel case studies within the broad framework of English for Academic Purposes (EAP). These provide results from classroom-based action research conducted over two years working with Semantics, Specialisation and axiological cosmologies from Legitimation Code Theory (LCT). Each author shares how one or both of these LCT dimensions have guided their practice in the teaching of English for academic writing and specifically, the development of their students’ critical dispositions by teaching them how to apply lenses to analyse texts so that they may make informed judgements. Data from classroom interventions and student writing are provided. It is hoped that this paper elicits further discussion in the growing field of applying LCT and may draw attention to the role of the EAP teacher as expert in linguistics and the need to focus more on knowledge in EAP writing courses.  相似文献
