RECEPTIVITY TO PEER TEACHING AND PEER LEARNING ABOUT THE SAFE AND APPROPRIATE USE OF MEDICATIONS AMONG OLDER ADULTS     

Jennie Y. Chou  Carolyn M. Brown 《Educational gerontology》2013,39(9):761-775

The purpose of this study was to assess receptivity to peer teaching and peer learning about the safe and appropriate use of medications among communitydwelling older adults. The sample was predominately White (88.5%), female (75.9%) older adults with an average age of 80.2 ( - 9.1) years. On average, the participants perceived their health status as good (2.8 - 0.6). In addition, participants reported using an average number of 4.4 ( - 3.3) prescribed medications. The majority (75%) of participants also reported no problems with their medications. With respect to receptivity to peer teaching and peer learning, the participants, on average, were neutral to peer teaching (6.0 - 2.4), but were somewhat receptive to peer learning (6.7 - 2.2). The number of prescribed medications that a participant reported taking and the age of a participant were identified as significant predictors of receptivity to peer teaching and accounted for 14.5% of the total variance ( F = 5.84, df = 2, p = 0.005). For receptivity to peer learning, the number of prescribed medications also was a significant predictor ( F = 7.50, df = 1, p = 0.008). This study provides the initial step to identifying community-dwelling older adults who would be receptive to peer teaching and peer learning about the safe and appropriate use of medications.  相似文献

Two Mandarin readers in Taiwan: characteristics of children with higher and lower reading proficiency levels     

Jia‐ling Charlene Yau 《Journal of Research in Reading》2005,28(2):108-124

This study investigated how two readers of Mandarin with differing reading‐proficiency skills interacted with a narrative passage, as well as what knowledge they brought to and made use of while reading the text. The perspectives of reading comprehension, transactional theory and social‐cognitive models of reading served as this study's theoretical framework. Two Sixth‐Grade participants were selected for inclusion through snowball sampling. The data in this study were obtained from interviews and think‐alouds. Qualitative analysis indicated that the skilled Mandarin reader's stance moved along the efferent/aesthetic continuum, while the less‐skilled Mandarin reader's was mainly efferent. The skilled reader employed strategies of inferencing, summarisation and synthesis during and after reading, while the less‐skilled reader applied bridging inferences, paraphrasing and repetition. The findings of this study corroborate previous findings that proficient readers employ more sophisticated approaches to reading than less‐proficient readers.  相似文献

Biofunctionalized nanoslits for wash-free and spatially resolved real-time sensing with full target capture     

Thierry Le?chlé  Chia-Fu Chou 《Biomicrofluidics》2015,9(3)

We propose biofunctionalized nanofluidic slits (nanoslits) as an effective platform for real-time fluorescence-based biosensing in a reaction-limited regime with optimized target capture efficiency. This is achieved by the drastic reduction of the diffusion length, thereby a boosted collision frequency between the target analytes and the sensor, and the size reduction of the sensing element down to the channel height comparable to the depletion layer caused by the reaction. Hybridization experiments conducted in DNA-functionalized nanoslits demonstrate the analyte depletion and the wash-free detection ∼10 times faster compared to the best microfluidic sensing platforms. The signal to background fluorescence ratio is drastically increased at lower target concentrations, in favor of low-copy number analyte analysis. Experimental and simulation results further show that biofunctionalized nanoslits provide a simple means to study reaction kinetics at the single-pixel level using conventional fluorescence microscopy with reduced optical depth.  相似文献   

��It depends on what science teacher you got��: urban science self-efficacy from teacher and student voices     

Virginia L. J. Bolshakova  Carla C. Johnson  Charlene M. Czerniak 《Cultural Studies of Science Education》2011,6(4):961-997

In the United States today, urban schools serve the majority of high-poverty and high minority populations including large numbers of Hispanic students. While many Hispanic students perform below grade level in middle school science, the science teaching community as a whole is lacking elements of diversity as teachers struggle to meet the needs of all learners. Researchers have recognized that science teacher effectiveness, one consequence of self-efficacy among teachers, is associated with future science achievement and science-related careers of their students. This qualitative study explores how three science teachers’ effectiveness in the classroom impacts students’ science self-efficacy beliefs at one urban middle school. Hispanic students were the focus of this investigation due to demographics and history of underperformance within this district. Teachers’ perspectives, as well as outside observer evaluations of instructional strategies and classroom climates were triangulated to explore dynamics that influence students’ interests and motivation to learn science using a framework to link teachers’ sense of efficacy (focusing on student outcomes). Findings suggest the impact teacher effectiveness can have on student outcomes, including strengthened student science self-efficacy and increased science achievement. Building awareness and support in teachers’ sense of efficacy, as well as developing respectful and supportive relationships between educator/facilitator and pupil during the transition to middle school may construct permanence and accomplishment for all in science.  相似文献   

Promoting discussion in peer instruction: Discussion partner assignment and accountability scoring mechanisms          下载免费PDF全文

Chih‐Yueh Chou  Pin‐Hsun Lin 《British journal of educational technology : journal of the Council for Educational Technology》2015,46(4):839-847

Peer instruction (PI) involves students answering questions and peer discussion learning activities. PI can enhance student performance and engagement in classroom instruction. However, some students do not engage in the discussions. This study proposes two mechanisms, discussion partner assignment and accountability scoring mechanisms, to form positive interdependence among students and individual accountability for each student to promote student discussions in PI. The evaluation results show that the student discussion rate with the promoting mechanisms is significantly higher than the rate without the mechanisms. The results from the questionnaire reveal that the mechanisms form positive interdependence and individual accountability to promote students to engage in the discussions.  相似文献   

Tandem array of nanoelectronic readers embedded coplanar to a fluidic nanochannel for correlated single biopolymer analysis     

Leonardo Lesser-Rojas  K. K. Sriram  Kuo-Tang Liao  Shui-Chin Lai  Pai-Chia Kuo  Ming-Lee Chu  Chia-Fu Chou 《Biomicrofluidics》2014,8(1)

We have developed a two-step electron-beam lithography process to fabricate a tandem array of three pairs of tip-like gold nanoelectronic detectors with electrode gap size as small as 9 nm, embedded in a coplanar fashion to 60 nm deep, 100 nm wide, and up to 150 μm long nanochannels coupled to a world-micro-nanofluidic interface for easy sample introduction. Experimental tests with a sealed device using DNA-protein complexes demonstrate the coplanarity of the nanoelectrodes to the nanochannel surface. Further, this device could improve transverse current detection by correlated time-of-flight measurements of translocating samples, and serve as an autocalibrated velocimeter and nanoscale tandem Coulter counters for single molecule analysis of heterogeneous samples.  相似文献
