Instruction in hematopathology at Mayo Medical School has evolved from instructor‐guided direct inspection under the light microscope (laboratory method), to photomicrographs of glass slides with classroom projection (projection method). These methods have not been compared directly to date. Forty‐one second‐year medical students participated in this pilot study, a prospective, randomized, crossover study measuring educational performance during a hematology pathophysiology course. The students were randomized to one of two groups. All students received the same didactic lectures in the classroom and subsequent case‐based review of peripheral blood smears using either laboratory or projection methods, on day one with a crossover to the other method on day two. Pre‐ and post‐test examinations centered on morphology recognition measured educational performance on each day, followed by a questionnaire identifying the student's favored method. There was no significant difference in the pre‐test and post‐test scores between the two teaching methods (rank‐sum P = 0.43). Students overwhelmingly preferred the projection method and perceived it as superior (76%), although post‐test scores were not significantly different. Student's recommended method was split with 50% favoring the projection method, 43% favoring a combined approach, and 23% noting logistical challenges to the laboratory. In this study, the laboratory and projection method were equivalent in terms of educational performance for hematopathology among medicals students. A classroom‐based approach such as the projection method is favored, given the large class sizes in undergraduate medical education, as well as the ergonomic challenges and additional resources required for large group instruction in a laboratory setting.

The Vanderbilt Assessment of Leadership in Education (VAL-ED) provides educators with a tool for principal evaluation based on principal, teacher, and supervisor reports of principals’ learning-centered leadership. In this study, we conduct a known group analysis as part of a larger argument for the validity of the VAL-ED in US elementary and secondary schools. We asked superintendents to select the principals in their district who they believe in performance of their duties are in the top 20 % and the bottom 20 %. We ask how accurately VAL-ED scores can identify membership of the two known groups. Using a discriminant analysis, the VAL-ED places principals in the superintendent groups, on average, 70 % of the time for both elementary and secondary schools. Placement accuracy is greater for the top group than the bottom group.  相似文献

Those entering the world of publishing standards for the first time may find it a baffling alphabet soup—with NISO, ANSI, BISG, IEEE, NIST, and ANSC floating on a broth bubbling with activity. Jacob and Rings sort out the acronyms, explaining what each of these groups does and how they interact. Mary Ellen L. Jacob, vice president for library planning at OCLC, is responsible for strategic planning activities regarding libraries and library services. Mrs. Jacob is also the board chair of the National Information Standards Committee. Deborah L. Rings, information analyst for library planning at OCLC, is responsible for identifying trends and factors relative to the library and information science areas, and for assessing their impact and potential impact on OCLC and its strategic planning processes.  相似文献

This paper describes the sexual socialisation process of marginalised, drug-using heterosexual black men, focusing primarily on the sources and content of sexual information. Analysing qualitative interview data, we discovered that the men in our sample both learn about sex and become sexually active at an early age. They most often learn about sex from the media and least often learn about sex from family members. The content of sexual information varies in specifics, but overall tends to equate sex with pleasure, encourage sexual activity with multiple partners and emphasise using protection. Our goal is to use this data to better understand how sexual socialisation contributes to the prevalence of multiple sexual partners and high rates of HIV among heterosexual black men in order to inform future risk-reduction intervention programmes.  相似文献

Active learning techniques have long been shown to increase the extent to which students are able to think critically about problems and solutions to them. The extant research suggests that efforts to engage students in higher order thinking should extend beyond the typical setting in which the more advanced students are introduced to active learning techniques. White and Frederiksen (2000 White, B. Y. and Frederiksen, J. R. 2000. “Metacognitive Facilitation: An Approach To Making Scientific Inquiry Accessible to All.”. In Inquiry into Learning and Teaching in Science, Edited by: Minstrell, J. L. and Van‐Zee, E. H. 33170. Washington, DC: American Association for the Advancement of Science.  [Google Scholar]) have found that most students, regardless of achievement levels, can reach a higher order thinking level when they are encouraged to do so. This paper explores several issues associated with active learning techniques in the general sense and then uses examples to demonstrate how such techniques can and are being used on the criminal justice classroom. The pros and cons of using active learning techniques are also discussed.  相似文献

Criminal justice programs at traditional institutions of higher learning have been moving toward offering courses online and, in some cases, placing entire programs online for the better part of the past decade. In competition with for‐profit institutions, many traditional colleges and universities have expanded their distance education programming to include online courses and programs to attract students. As a result, the number of criminal justice students has increased, as have the profits for home institutions. With this growth in the online education market, the criminal justice faculty member has been thrust, willingly or unwillingly, into the world of online teaching—a method of instruction foreign to many instructors. From the authors’ experience at their current (and in the case of the lead author a second) institution, this paper addresses many issues that must be considered by faculty members before embarking on this type of time‐intensive initiative.  相似文献

This article assesses the quality of 12 American doctoral programs by counting the number of publications of their Ph.D. graduates in a large number of criminology and criminal justice journals, and in 20 more “academic” journals. While half of the Ph.D. graduates had no publications, the 4 percent who were the most productive (the “stars”) accounted for one third of all journal articles. Publication rates up to graduation predicted publication rates after graduation. The University of Maryland, Michigan State University, the University of California at Irvine, Florida State University, and Sam Houston State University had the most productive Ph.D. graduates in academic journals. There was a significant correlation between the productivity of a program's Ph.D. graduates and the productivity of its faculty members. The academic publication rate was influenced most by prevalence (the percentage of Ph.D.s with at least one publication), rather than by the percentage of “stars” or the frequency of publications.  相似文献
