A semester-long student-directed research project involving enzyme immunoassay: appropriate for immunology, endocrinology, or neuroscience courses     

Ramos Goyette S  DeLuca J 《CBE life sciences education》2007,6(4):332-342

The following project aimed at promoting integrated and long-lasting learning is described for an Immunology course, but it may be adapted to other disciplines. Students were asked to develop and carry out a research project to examine the relationship between immune function and stress. The experiments were required to include the assessment of salivary cortisol and salivary IgA (sIgA) with enzyme immunoassays. All other aspects of the experiments were developed by student groups with appropriate guidance from the instructor. Data are presented for one group project that assessed the effect of music on cortisol and sIgA. Overall levels of sIgA and cortisol were consistent with reported values. Students found a significant decrease in cortisol over time. Additionally, there was a trend that supported the overall student hypothesis regarding the effect of stress and immune function. Compared with the same Immunology course that included an instructor-designed experiment using enzyme immunoassays for cortisol and sIgA, several assessments (e.g., final grades and comments on student evaluations) show that overall learning seemed to be much better in the course with the student-directed research project.  相似文献   

Wendell Berry on Education: A Cultural Inheritance of Care     

Jane M. Schreck 《Educational Studies A Journal of the American Educational Studies Association》2019,55(3):315-326

Although recognized for his wisdom on issues of agriculture, ecology, economics, and theology, writer Wendell Berry has been largely ignored for his thinking on education. Yet the same good sense and clear thinking that he applies to other areas of thought can be seen also in his writings on education. This article reviews what scholars have observed about Berry’s ideas on education, and then contextualizes his thinking through a comparison with two giants of educational theory: John Dewey and Paulo Freire. Berry’s local focus and his emphasis on community and the ecosphere create a vision for education that could lead to a healthier, more peaceable world.  相似文献   

Undergraduate Medical Students' Usage and Perceptions of Anatomical Case-Based Learning: Comparison of Facilitated Small Group Discussions and eLearning Resources     

Jane C. Holland  Teresa Pawlikowska 《Anatomical sciences education》2019,12(3):245-256

While case-based discussions can empower students to apply knowledge to contextual clinical situations, scheduling these activities is a challenge in crowded curricula. Case-based eLearning activities, derived from existing cases discussed within anatomy small group tutorials, were created incorporating principles such as interactivity, reinforcement, and feedback. Over half of the students accessed one or more of these online cases, with 18% accessing all eight online cases provided. Access increased as the semester progressed, particularly just before summative examinations, implying students used these primarily as revision aides. Students rated both formats highly, but favored the online format with regard to enjoyment (P = 0.048), learning (P = 0.101), and feedback (P = 0.086). However, more students discussed these cases in small group tutorials within the anatomy dissecting room than completed them online (122 vs. 67) and themes emerging from free text comments included a desire to have more time dedicated to these cases during small group tutorials, and an appreciation for the opportunity for discussion with staff and learning through doing. Additionally, native English speakers rated the anatomy room discussions significantly higher in all aspects than non-native English speakers, suggesting that non-native speakers may be hesitant or reluctant to fully participate in front of peers. While online case-based learning activities are a useful adjunct to anatomy teaching, particularly for revision, assumptions that “digital natives” have an innate preference for digital resources require critical evaluation, as students still place a high value on opportunities for discussion with staff during their studies.  相似文献   

Comparison of personality profiles for intellectually gifted students and students outstanding in the fine and performing arts attending self-contained secondary schools     

Frances A. Karnes  Jane C. Chauvin  Timothy J. Trant 《Psychology in the schools》1985,22(2):122-126

The study included 199 intellectually gifted students and 176 students in the fine and performing arts who were administered the High School Personality Questionnaire. The results indicated that the gifted students obtained higher Leadership Potential scores, while the talented students scored higher in Creativity. Several significant differences were found in the personality profiles of the two groups.  相似文献

A methodological approach in the evaluation of the efficacy of treatments for the dimensional stabilisation of waterlogged archaeological wood     

Gianna Giachi  Chiara Capretti  Nicola Macchioni  Benedetto Pizzo  Ines Dorina Donato 《Journal of Cultural Heritage》2010,11(1):91-101

The aim of the work is to set up a methodological approach to verify the effectiveness of the treatments of decayed waterlogged archaeological wood and to point out the proper thermo-hygrometric conditions for its preservation after treatment. The treatments were performed on wood samples of maritime pine (Pinus pinaster Aiton), oak (Quercus sp. caducifolia), elm (Ulmus cf. minor) and strawberry tree (Arbutus unedo L.), obtained from stems pertaining to the original vegetation found in the excavation site of the Ancient Ships in Pisa (Italy), and dated from seventh century BC to second century AD The utilised products were: Polyethylene Glycols (PEG) of various molecular weights, a Polypropylene Glycol (PPG 425), Trehalose (α-D-glucopyranosyl-α-D-glucopyranoside), and their mixtures, and also a Hydroxypropylcellulose (Klucel). The main objective to be pursued by the treatments was considered the stabilisation of the original size and shape of samples. The various steps of this approach were: the execution of a preliminary diagnostic survey on untreated samples; the characterisation of treatment solutions ‘as such’ to establish the property to be monitored during the treatment; the evaluation of the main physical characteristics of wood after the treatment were determined. Among the latter, the coefficient of dimensional stability during the exposure to a series of selected thermo-hygrometric conditions and the retention of consolidants after the treatment. These two measurements allowed the definition of the ‘efficacy of a treatment’, φ_T, a new parameter firstly utilised in this work. It measures the stabilisation capability of the percent unit of retained product, and its value permits to put in evidence the consolidants that stabilise wood with the lowest amount of product. Conversely, it was not possible to measure the Anti-Shrink Efficiency (ASE), one of the most utilised parameters for the evaluation of treatments, because of the serious distortions and fractures observed in all the heavily degraded untreated samples.  相似文献   

Compensatory changes in physical activity and sedentary time in children and adolescents with cystic fibrosis     

Kelly A. Mackintosh  Nicola D. Ridgers  Melitta A. McNarry 《Journal of sports sciences》2019,37(13):1506-1511

Physical activity (PA) is a key element in Cystic Fibrosis (CF) treatment strategies, yet little is known as to whether activity compensation occurs. This study examined whether PA and/or sedentary time on one day were temporally associated with time spent in these intensities the following day in youth with CF. Time spent sedentary and in different PA intensities were objectively-measured for seven consecutive days in 50 youth (22 boys; 12.0 ± 2.7 years); 25 with mild-to-moderate CF and 25 age- and sex-matched controls. Multilevel analyses (day and child) were conducted using generalised linear latent and mixed models. On any given day, every additional 10 minutes spent in sedentary time or moderate-to-vigorous physical activity (MVPA) were associated with 1.9 (95%CI: ?3.6 to ?1.2) and 12.4 (95%CI: ?22.1 to ?2.9) minutes less sedentary time the following day, respectively. These temporal associations were also observed when split by group (3.1 vs. 1.9 minutes for healthy and CF, respectively). These findings indicate that youth do not compensate their PA, irrespective of disease status, between days, but may compensate their sedentary time between days. Experimental studies are warranted to fully elucidate whether compensatory responses to PA and sedentary time occur, which is fundamental for informing PA promotion strategies.  相似文献   

Designing,building, measuring,and testing a constant equivalent fall height terrain park jump     

Nicola Petrone  Matteo Cognolato  James A. McNeil  Mont Hubbard 《Sports Engineering》2017,20(4):283-292

Previous work has presented both a theoretical foundation for designing terrain park jumps that control landing impact and computer software to accomplish this task. US ski resorts have been reluctant to adopt this more engineered approach to jump design, in part due to questions of feasibility. The present study demonstrates this feasibility. It describes the design, construction, measurement, and experimental testing of such a jump. It improves on the previous efforts with more complete instrumentation, a larger range of jump distances, and a new method for combining jumper- and board-mounted accelerometer data to estimate equivalent fall height, a measure of impact severity. It unequivocally demonstrates the efficacy of the engineering design approach, namely that it is possible and practical to design and build free style terrain park jumps with landing surface shapes that control for landing impact as predicted by the theory.  相似文献
