SMAR2T: Science and Mathematics Academy for the Recruitment and Retention of Teachers is an NSF-funded project for the alternative
certification of science and mathematics teachers. Since 2003, we have recruited 4 cohorts of students for 2 different routes
to postbaccalaureate teacher certification for teaching grades 5–12. Because we did not meet our target numbers for the recruitment
of the 1st cohort, we examined our recruitment strategies and their effects. In this paper, we discuss strategies used to
recruit for the 1st SMAR2T cohort and the outcomes of those strategies. We present ongoing recruitment efforts and data on inquiries and applicants
for the 2nd cohort. Finally, we highlight the intentional and unintentional gatekeepers of our program and present implications
for others engaged in designing and implementing alternative pathways certification. 相似文献

The nature of physical activity that benefits bone is traditionally thought to differ from that benefiting cardiovascular health. Accordingly, exercise recommendations for improving bone health and cardiovascular health are largely incongruent. Our aim was to determine the associations between high-impact physical activity participation and both cardiovascular disease risk factors and bone mass. We recruited 94 men and women (age 34.0?±?13.3 years) to undergo measures of cardiovascular disease risk (BMI, total cholesterol, fasting blood glucose, waist-to-hip ratio, and mean arterial pressure) and dual-energy X-ray absorptiometry (DXA XR-800, Norland) measures of bone mass (femoral neck, lumbar spine, and whole body BMD) and body composition (whole body lean mass and fat mass). Physical activity participation was estimated using the bone-specific physical activity questionnaire (BPAQ). Those in the upper tertile for current BPAQ score exhibited lower total cholesterol, waist-to-hip ratio, and mean arterial pressure than those in the lower tertiles (P?0.05) with the relationship being mild-to-moderate (r?=??0.49 to 0.29, P?0.01). Those in the upper tertile for BPAQ score also had greater lumbar spine BMD than those in the lower tertile (P?=?0.008), with BPAQ score predicting 6% of the variance in BMD (P?=?0.02). We conclude that high-impact physical activity as captured by the BPAQ may be beneficial for both bone health and for attenuating cardiovascular disease risk. 相似文献

Special needs care has taken on a substantial evolution within education. Special educational needs coordinators (SENCOs) are no longer considered to provide individual guidance to students but to support and professionalize regular teachers in fulfilling special needs care in their classroom. In doing so, they act as teacher leaders. Many concerns are raised about how teacher leadership may interfere with the existing working relationships in schools. In this study, we use Positioning Theory as a theoretical approach to obtain an in-depth understanding of how the position of the SENCO and the responsibilities attached to this position are negotiated within the school. The findings illustrate that SENCOs received the legitimacy to act as teacher leaders when their expertise was recognized, when teachers perceived their task as first-line helpers, and when school principals were willing to release power. 相似文献

A high school education prepares young people to participate positively in the economy and in civic life, among other positive life outcomes. However, nearly one in five American high school students does not graduate from high school on time, if ever. Progress has been made on understanding why students fail to complete high school and on raising graduation rates. Previous reviews and syntheses of this literature have focused on identifying factors that put students at risk for dropping out of school. Less is understood regarding what assets can promote high school graduation. Therefore, we reviewed research from the past 25 years on high school graduation, focusing on longitudinal, US-based studies of malleable factors that predict graduation. Through this systematic search, we identified 12 assets in individual, family, school, peer, and community contexts, which predict high school graduation, as well as identified assets for which more research is needed. Implications for policy and practice and directions for future research are discussed. 相似文献

In the communication of scientific concepts the nature of instruction is such that the instructor must frequently be more explicit than the scientist himself. The naive questions of students often raise problems of fundamental semantic and philosophical importance ignored by scientists. Many of the epistemic problems so raised require a clarification of the relations between space and time. The present paper discusses the empirical conditions for this clarification.The first part of this article appeared in Instructional Science Vol. 1 No.1. 相似文献

Understanding the reasons that individuals drop out of high school is fundamental to improving intervention efforts to promote graduation. The authors present a mixed methods analysis of the reasons individuals drop out of high school before graduating. Using a survey methodology with young adults who left school before graduating (N?=?1,047, M age?=?21.5?years, SD?=?2.2 years, age range =18–25 years), the authors assessed ongoing life stressors, as well as the turning points individuals identified as the top reason for why they left school. Qualitative analysis provided seven categories of turning points: mobility, family, peers, school engagement and environment, health, crime, and multiple categories. More than half of respondents indicated that the reason they dropped out was related to school engagement and environment. Results showed differences across profiles of lived experiences, reported turning points, and sex. 相似文献

In early 2020, the Covid-19 crisis forced medical institutions worldwide to convert quickly to online platforms for content delivery. Although many components of medical education were adaptable to that format, anatomical dissection laboratory lost substantial content in that conversion, including features of active student participation, three-dimensional spatial relationships of structures, and the perception of texture, variation, and scale. The present study aimed to develop and assess online anatomy laboratory sessions that sought to preserve benefits of the dissection experience for first-year medical students. The online teaching package was based on a novel form of active videography that emulates eye movement patterns that occur during processes of visual identification, scene analysis, and learning. Using this video-image library of dissected materials, content was presented through asynchronous narrated laboratory demonstrations and synchronous/active video conference sessions and included a novel, video-based assessment tool. Data were obtained using summative assessments and a final course evaluation. Test scores for the online practical examination were significantly improved over those for previous in-person dissection-based examinations, as evidenced by several measures of performance (Mean: 2015–2019: 82.5%; 2020: 94.9%; P = 0.003). Concurrently, didactic test scores were slightly, but not significantly, improved (Mean: 2015–2019: 88.0%; 2020: 89.9%). Student evaluations of online sessions and overall course were highly positive. Results indicated that this innovative online teaching package can provide an effective alternative when in-person dissection laboratory is unavailable. Although this approach consumed considerable faculty time for video editing, further development will include video conference breakout rooms to emulate dissection small-group teamwork. 相似文献

Research on University-industry (U-I) linkages and their determinants has increased significantly in the past few years. However, there is still controversy on the key factors explaining the formation of U-I linkages, and especially related to individual researcher characteristics. This paper provides new empirical evidence and, in particular, looks at the importance of researchers’ individual characteristics and their institutional environments in explaining the propensity to engage in different types of U-I linkages. Based on an original dataset, we present new evidence on three wine producing areas - Piedmont, a region of Italy, Chile and South Africa - that have successfully responded to recent structural changes in the industry worldwide. Empirical findings reveal that researchers’ individual characteristics, such as centrality in the academic system, age and sex, matter more than publishing records or formal degrees. Institutional specificities at country level also play a role in shaping the propensity of researchers to engage with industry. 相似文献

Red lake pigments and dyes used in works of art were characterized by microspectrofluorimetry, a new tool in the field of cultural heritage. Emission and excitation spectra were obtained with high spatial resolution (8–30 μm) in cross-sections from paintings by Vincent van Gogh and Lucien Pissarro and from millenary Andean textiles. The fluorophores were identified by comparing their spectra with those from historic reconstructions assembled in a database. In the paints, purpurin and eosin lakes were detected. In the Paracas and Nasca textiles, dated from 200 B.C. to A.D.1476, purpurin and pseudopurpurin were the red dyes used. Carminic acid was detected in textiles dated close to the Inca Empire, A.D. 1000–1476. The results obtained with this new technique were confirmed and are in agreement with those obtained with conventional methods, requiring microsampling, such as HPLC-DAD-MS and SEM-EDX. 相似文献

Rats searched for food hidden on top of poles in a 4 × 4 matrix of poles. Before each trial, the location of the four baited poles was unpredictable. However, the poles were always baited in one of two spatial patterns, either a square or a line. The food hidden on the four baited poles was one of two types, and the food type determined the identity of the pattern. Thus, once one baited pole was discovered, the food type provided a cue for the spatial pattern in which the remaining food was hidden. The results showed that rats learned the two spatial patterns in which the food was hidden and used the conditional cue to determine which pattern was relevant on individual trials, thereby increasing the efficiency of spatial search. 相似文献
