Enhancing motivation in adult learners is often a difficult task in today’s college classroom. Significant reforms in America’s educational system have directed the initiative to adopt Common Core Standards in Language Arts by all 50 states. With the focus on increased rigor and depth of understanding in learning, the hope is to prepare students throughout the K–12 sequence for college and careers. This new instructional model requires moving students from passive recipients to active learners. Although the arrival of an expanding population is encouraging for college communities, the issue of underprepared college students must be addressed. Instructional methods designed to cultivate active learning and critical thinking through more contextualized, hands-on teaching activities produced initial evidence of improved reading achievement. 相似文献

The written English vocabulary of 72 deaf elementary school students of various proficiency levels in American Sign Language (ASL) was compared with the performance of 60 hearing English-as-a-second-language (ESL) speakers and 61 hearing monolingual speakers of English, all of similar age. Students were asked to retell "The Tortoise and the Hare" story (previously viewed on video) in a writing activity. Writing samples were later scored for total number of words, use of words known to be highly frequent in children's writing, redundancy in writing, and use of English function words. All deaf writers showed significantly lower use of function words as compared to their hearing peers. Low-ASL-proficient students demonstrated a highly formulaic writing style, drawing mostly on high-frequency words and repetitive use of a limited range of function words. The moderate- and high-ASL-proficient deaf students' writing was not formulaic and incorporated novel, low-frequency vocabulary to communicate their thoughts. The moderate- and high-ASL students' performance revealed a departure from findings one might expect based on previous studies with deaf writers and their vocabulary use. The writing of the deaf writers also differed from the writing of hearing ESL speakers. Implications for deaf education and literacy instruction are discussed, with special attention to the fact that ASL-proficient, deaf second-language learners of English may be approaching English vocabulary acquisition in ways that are different from hearing ESL learners. 相似文献

Abstract In this study, we examined the correlations between selected markers of isometric training intensity and subsequent reductions in resting blood pressure. Thirteen participants performed a discontinuous incremental isometric exercise test to volitional exhaustion at which point mean torque for the final 2-min stage (2min-torquepeak) and peak heart rate peak (HRpeak) were identified. Also, during 4 weeks of training (3 sessions per week, comprising 4 × 2 min bilateral leg isometric exercise at 95% HRpeak), heart rate (HRtrain), torque (Torquetrain), and changes in EMG amplitude (ΔEMGamp) and frequency (ΔEMGfreq) were determined. The markers of training intensity were: Torquetrain relative to the 2min-torquepeak (%2min-torquepeak), EMG relative to EMGpeak (%EMGpeak), HRtrain ΔEMGamp, ΔEMGfreq, and %MVC. Mean systolic (?4.9 mmHg) and arterial blood pressure (?2.7mmHg) reductions correlated with %2min-torquepeak (r = ?0.65, P = 0.02 and r = ?0.59, P = 0.03), ΔEMGamp (r = 0.66, P = 0.01 and r = 0.59, P = 0.03), ΔEMGfreq (r = ?0.67, P = 0.01 and r = ?0.64, P = 0.02), and %EMGpeak (systolic blood pressure only; r = ?0.63, P = 0.02). These markers best reflect the association between isometric training intensity and reduction in resting blood pressure observed after bilateral leg isometric exercise training. 相似文献

This investigation provides an extensive review of scientific, religious, and otherwise non-scientific factors that may influence student acceptance of biological evolution. We also measure the extent to which students' levels of acceptance changed following an educational experience designed to address an inclusive inventory of factors identified as potentially affecting student acceptance of evolution (n = 81, pre-test/post-test) n = 37, one-year longitudinal). Acceptance of evolution was measured using the Measure of Acceptance of the Theory of Evolution (MATE) instrument among participants enrolled in a secondary-level academic programme during the summer prior to their final year of high school and as they transitioned to the post-secondary level. Student acceptance of evolution was measured to be significantly higher than initial levels both immediately following and over one year after the educational experience. Results reported herein carry implications for future quantitative and qualitative research as well as for cross-disciplinary instruction plans related to evolutionary science and non-scientific factors which may influence student understanding of evolution. 相似文献

Too little consideration has been given to the potential dangers underlying program development for older adults. These dangers are exemplified by the inability of program designers to share their expertise. A close examination of current educational efforts serving the older adult reveals that past inadequacies and present growth trends demand more realistic approaches. More people are going to reach the age of 65; shifts in population demand shifts in priorities. This paper attempts to focus on emerging problems associated with program development. Territoriality becomes a central issue in determining who should develop and implement programs for and about older people. The audiences to which this paper is addressed are educators and gerontologists. The prime question raised is: “Can collaborative efforts between gerontologists and educators improve current program quality?" 相似文献

As literacy grows in importance, policymakers’ demands for programme quality grow, too. Evidence on the effectiveness of adult and family literacy programmes is limited at best: research gaps abound, and programme evaluations are more often than not based on flawed theories of programme impact. In the absence of robust evidence on the full range of short- and long-term programme impacts, it is difficult to accurately measure intervention effectiveness. Too frequently, researchers and policymakers focus only on short-term, easily measured outcomes, creating a ‘tyranny of effect size’ that may systematically underestimate impact while simultaneously distorting practice. However, the answer does not lie in turning away from quantitative research. Doing so will consign adult and family literacy to the margins of public policy, when they should be in the mainstream. Longitudinal research from Turkey and the US suggests a need for revised, more subtle theories of how adult literacy and family literacy programmes work, and the diverse ways they benefit participants. By working together more closely and intelligently, researchers, policymakers and practitioners can develop evaluation strategies that more accurately measure programme effects. The key is combining methodological rigour with fully fleshed out theories of literacy development and programme impact. 相似文献

There is little published data in relation to the effects of caffeine upon cycling performance, speed and power in trained cyclists, especially during cycling of approximately 60 s duration. To address this, eight trained cyclists performed a 1 km time-trial on an electronically braked cycle ergometer under three conditions: after ingestion of 5 mg x kg-1 caffeine, after ingestion of a placebo, or a control condition. The three time-trials were performed in a randomized order and performance time, mean speed, mean power and peak power were determined. Caffeine ingestion resulted in improved performance time (caffeine vs. placebo vs. control: 71.1 +/- 2.0 vs. 73.4 +/- 2.3 vs. 73.3 +/- 2.7 s; P = 0.02; mean +/- s). This change represented a 3.1% (95% confidence interval: 0.7-5.6) improvement compared with the placebo condition. Mean speed was also higher in the caffeine than placebo and control conditions (caffeine vs. placebo vs. control: 50.7 +/- 1.4 vs. 49.1 +/- 1.5 vs. 49.2 +/- 1.7 km x h-1; P = 0.0005). Mean power increased after caffeine ingestion (caffeine vs. placebo vs. control: 523 +/- 43 vs. 505 +/- 46 vs. 504 +/- 38 W; P = 0.007). Peak power also increased from 864 +/- 107 W (placebo) and 830 +/- 87 W (control) to 940 +/- 83 W after caffeine ingestion (P = 0.027). These results provide support for previous research that found improved performance after caffeine ingestion during short-duration high-intensity exercise. The magnitude of the improvements observed in our study could be due to our use of sport-specific ergometry, a tablet form and trained participants. 相似文献
