托尼的美国梦

他来自意大利一个石场,在罗马南边的某个地方。他何时、如何到美国的,我不得而知。但一天晚上,我看见他正站在我家车库后面的车道上,大约五英尺七英寸或者八英寸高,瘦瘦的。     

Assessing the integration of audience response system technology in teaching of anatomical sciences

The goals of our study were to determine the predictive value and usability of an audience response system (ARS) as a knowledge assessment tool in an undergraduate medical curriculum. Over a three year period (2006–2008), data were collected from first year didactic blocks in Genetics/Histology and Anatomy/Radiology (n = 42–50 per class). During each block, students answered clinically oriented multiple choice questions using the ARS. Students' performances were recorded and cumulative ARS scores were compared with final examination performances. Correlation coefficients between these variables were calculated to assess the existence and direction of an association between ARS and final examination score. If associations existed, univariate models were then constructed using ARS as a predictor of final examination score. Student and faculty perception of ARS difficulty, usefulness, effect on performance, and preferred use were evaluated using a questionnaire. There was a statistically significant positive correlation between ARS and final examination scores in all didactic blocks and predictive univariate models were constructed for each relationship (all P < 0.0001). Students and faculty agreed that ARS was easy to use and a reliable tool for providing real‐time feedback that improved their performance and participation. In conclusion, we found ARS to be an effective assessment tool benefiting the faculty and the students in a curriculum focused on interaction and self‐directed learning.

Development and initial investigation of a self-report measure of teachers’ readiness to implement

This paper describes development and piloting of a self-report measure of teachers’ readiness to implement evidence-based programs. Using mixed methods, this project proceeded in two phases. In the first phase, a program-independent self-report measure of readiness to implement was developed and piloted with N?=?53 teachers. Results of quantitative analyses offer initial support for the structure and utility of this scale. In the second phase, qualitative interviews were conducted with a subset of the overall sample in order to more thoroughly understand teachers’ experiences of readiness and implementation. Together, results contribute to further scale development and offer preliminary support for the validity of this measure in assessing readiness.     

Methodological considerations for studying science-in-the-making in educational settings

In this paper we explore the methodological implications of sociocultural approaches for the study of scientific knowledge and practices. Research in science studies and science education is reviewed with a focus on methodological considerations. Informed by empirically-based studies of scientific practices from multiple disciplinary perspectives, we describe our perspective for investigating science education which combines ethnography and discourse analysis. This theoretical position on the discursive nature of the social construction of school science-in-the-making forms the basis for theoretical and methodological critique and discussion. We provide a review of the history of nature of science (NOS) research to trace the methodological influence of Science and Technology Studies in science education. Four methodological issues associated with studying science as cultural practices are discussed: the local and contingent nature of situated definitions of science; theory dependence and coherence of research methodologies; attention to the study of school science-in-the-making; and reflexivity.     

Evaluating the impact of library services on the quality and cost of medical care

Recent federal regulations have minimized the role of the hospital library in contributing to the quality of medical care and in lowering hospital costs. We trace the events that have led to these assumptions and discuss the complex problem of evaluating the impact of library services. Current research on the value and effectiveness of information is outlined.
