We have developed a wet lab DNA microarray simulation as part of a complete DNA microarray module for high school students. The wet lab simulation has been field tested with high school students in Illinois and Maryland as well as in workshops with high school teachers from across the nation. Instead of using DNA, our simulation is based on pH indicators, which offer many ideal teaching characteristics. The simulation requires no specialized equipment, is very inexpensive, is very reliable, and takes very little preparation time. Student and teacher assessment data indicate the simulation is popular with both groups, and students show significant learning gains. We include many resources with this publication, including all prelab introductory materials (e.g., a paper microarray activity), the student handouts, teachers notes, and pre- and postassessment tools. We did not test the simulation on other student populations, but based on teacher feedback, the simulation also may fit well in community college and in introductory and nonmajors' college biology curricula. 相似文献

Over the past decades research on learning has become more diverse and complex. The concern expressed by Alexander, Schallert, and Reynolds (2009/this issue) is that this diversity of theoretical perspectives has resulted in a fragmentation that is destructive to the field. Although it is important to engage in explicit discussions of how learning is construed in different traditions, Alexander et al. do not give sufficient recognition to the significant epistemological and theoretical differences between traditions; differences that make them incompatible in important respects, for instance, with respect to their units of analysis. An acceptance of incompatibilities in perspectives is not necessarily a problem. In fact, such a situation may, if the debates are grounded in a mutual acceptance of the diverse manners in which knowing and learning may be theorized, give us a richer frame of reference from which to analyze learning in its various manifestations in complex societies. 相似文献

The Genome Consortium for Active Teaching (GCAT) facilitates the use of modern genomics methods in undergraduate education. Initially focused on microarray technology, but with an eye toward diversification, GCAT is a community working to improve the education of tomorrow's life science professionals. GCAT participants have access to affordable microarrays, microarray scanners, free software for data analysis, and faculty workshops. Microarrays provided by GCAT have been used by 141 faculty on 134 campuses, including 21 faculty that serve large numbers of underrepresented minority students. An estimated 9480 undergraduates a year will have access to microarrays by 2009 as a direct result of GCAT faculty workshops. Gains for students include significantly improved comprehension of topics in functional genomics and increased interest in research. Faculty reported improved access to new technology and gains in understanding thanks to their involvement with GCAT. GCAT's network of supportive colleagues encourages faculty to explore genomics through student research and to learn a new and complex method with their undergraduates. GCAT is meeting important goals of BIO2010 by making research methods accessible to undergraduates, training faculty in genomics and bioinformatics, integrating mathematics into the biology curriculum, and increasing participation by underrepresented minority students. 相似文献

在香港经济经历数次冲击之后，中央政府为促进内地和香港特别行政区经济的共同繁荣与发展，加强双方与其他国家和地区的经贸联系，达成了《内地与香港关于建立更紧密经贸关系的安排》(简称CEPA)。CEPA的实施使香港和内地的房地产业取长补短，优势互补，尤其令内地的房地产业加快了由相对“封闭”走向开放、走向国际化的步伐。 相似文献

In this paper, I draw on observations from sexual health workshops in an elementary school classroom in Vancouver, Canada and friendship pair interviews with four boys who attended the workshops. I examine how the educators organising the workshops constructed sexual health, highlighting their reliance on both a ‘gay is okay’ and a scientific discourse. I argue that by locating their discussion of homosexuality within a values framework and striving to depict gay relationships as acceptable, they simultaneously constituted homosexuality as requiring acceptance. Likewise, by subsuming references to heterosexuality within their lesson on (hetero)sexual reproduction, they framed heterosexuality as an always already accepted scientific fact. Having set the scene in this way, I then explore the ways the boys both took up and deviated from these discourses when constructing their own narratives. 相似文献
