To effectively help urban pre-service teachers to provide civic education opportunities in their future classrooms, teacher educators should know how urban pre-service teachers themselves conceptualize citizenship and civic engagement. Through the research question—how do urban K-6 pre-service teachers currently enrolled in an urban education teacher certification program at a 4-year university construct key concepts and ideologies about citizenship and civic education?—we examined how 15 pre-service teachers understood these concepts. Using three conceptions of citizenship—personally responsible citizen, participatory citizen, and justice-oriented citizen (Westheimer and Kahne in Am Educ Res J 41(2):237–269, 2004)—our analysis demonstrated that urban pre-service teachers’ conceptions of their students’ lives significantly influenced their ideas about civic education in elementary schools. Although the participating pre-service teachers overwhelmingly promoted personally responsible citizenship, we found the participants to heavily weigh developmentally appropriate practice and classroom context when considering the risks and rewards of promoting justice-oriented citizenship in elementary classrooms. 相似文献

Low serum vitamin D level has an increased association with risk of multiple sclerosis (MS).There has been no published data on the levels of this vitamin in Indian population with MS. Hence we decided to undertake this study to document if there is evidence of vitamin D deficiency in patients with MS in our population. 26 patients with diagnosis of MS by modified Mc Donald’s criteria were enrolled in this study. Serum vitamin D (1,25 hydroxy) levels were measured by electro-chemiluminescence in our biochemistry lab. An age-matched control group of 202 patients who did not have a diagnosis of MS were included. In our study group 76.9 % had vitamin D level less than 20 ng/ml compared to 65.5 % of control group (p value of 0.019). Our study revealed a trend towards low vitamin D values in Indian MS patients. 相似文献

This paper proposes a simple method to evaluate batsmen and bowlers in cricket. The idea in this paper refines ??book cricket?? and evaluates a batsman by answering the question: How many runs a team consisting of same player replicated eleven times will score? 相似文献

Our immune system, by and large, does a fine job in protecting us from opportunistic and infectious microbes, potential carcinogens and allergens. It is therefore crucial to understand the organization of the immune network. This article focuses on some important features and key players involved in adaptive immune response. The first part of the article dealt with the humoral immune response mediated mainly by immunoglobulins produced by the B cells. The second part deals with T cells, the Major Histocompatibility Complex (MHC)-encoded molecules, and Recombination Activating Genes (RAG) responsible for generating diverse B-cell receptors (BCR) and T-cell receptors (TCR). With the advent of newer and smarter infectious agents, it is important to understand the working of the immune network as more research in this area may facilitate the development of better protective strategies. 相似文献

This paper estimates the impact of private education on the academic achievement of low-income students in Chile. To deal with selection bias, we use propensity score matching to compare the test scores of reduced-fee paying, low-income students in fee-charging private voucher schools to those of similar students in public schools and free private voucher schools. Our results reveal that students in fee-charging private voucher schools score slightly higher than students in public schools. The difference in standardized test scores is approximately 10 points, a test score gain of 0.2 standard deviations. We find no difference in the academic achievement of students in the fee-charging private voucher treatment group relative to their counterparts in free private voucher schools. 相似文献

Preparation of tests and student's assessment by the instructor are time consuming. We address these two tasks in neuroanatomy education by employing a digital media application with a three‐dimensional (3D), interactive, fully segmented, and labeled brain atlas. The anatomical and vascular models in the atlas are linked to Terminologia Anatomica. Because the cerebral models are fully segmented and labeled, our approach enables automatic and random atlas‐derived generation of questions to test location and naming of cerebral structures. This is done in four steps: test individualization by the instructor, test taking by the students at their convenience, automatic student assessment by the application, and communication of the individual assessment to the instructor. A computer‐based application with an interactive 3D atlas and a preliminary mobile‐based application were developed to realize this approach. The application works in two test modes: instructor and student. In the instructor mode, the instructor customizes the test by setting the scope of testing and student performance criteria, which takes a few seconds. In the student mode, the student is tested and automatically assessed. Self‐testing is also feasible at any time and pace. Our approach is automatic both with respect to test generation and student assessment. It is also objective, rapid, and customizable. We believe that this approach is novel from computer‐based, mobile‐based, and atlas‐assisted standpoints. Anat Sci Educ 2:244–252, 2009. © 2009 American Association of Anatomists. 相似文献
