Integrated Use of Scanning Electron Microscopy in Multidisciplinary Curricula in Classroom and Field Settings

跨学科(99)这项建议解决了本科科学教育中的两个弱点。1)传统的自然科学教育缺乏跨学科联系。这项建议旨在通过增加新课程和利用扫描电子显微镜(SEM)的新实验室练习来加强布鲁姆斯堡大学自然科学的跨学科教育，作为环境科学新的多学科计划的一部分。2)沃洛普斯岛海洋科学中心(WIMSC)已经开设了海洋科学的跨学科课程，布鲁姆斯堡大学是该中心的成员。这个中心是暑期课程和学生和教职员工研究的野外站，但作为传统的野外站，它缺乏先进的分析设备。扫描电子显微镜的增加将提供一个在现场使用分析技术的独特机会。该提案要求提供资金，用于购买一个小型扫描电子显微镜模型，该模型将在学年期间在布鲁姆斯堡校区用于新环境科学课程中的实验室练习，以及用于生物学和地质学课程中其他课程的实验室，以及用于学生研究。在夏季的几个月里，这台机器将在WIMSC使用，主要用于多学科海洋科学课程的教学。由于它成功地融入了多个学科的本科教育，因此该课程改革是一个合乎逻辑的选择。扫描电子显微镜在课堂和田野中的使用方式受到了O L.S.Chumbley等人的影响。《一种新的范式--多用户扫描电子显微镜》，《显微镜杂志》，1995年9月。O J.H.Wandersee，“生物仪器：理解生命的工具”，全国生物学教师协会(弗吉尼亚州雷斯顿：1996)。O G.E.Sosinsky et.电子显微复制扩展计划：基于网络的研究和教育资源，《结构生物学杂志》，第125卷，1999年，第246-252页。O.P.D.Crowley和J.T.Cheney，《在本科生矿物学中使用微探针(SEM/EDS)》，《美国地质学会摘要与程序》，第25卷，第6期，1993年，第347-348页。以下是在学生研究项目中使用扫描电子显微镜的方法的例子：O C.Jones，《更新世和新近变异粘土的显微组构分析》，美国地质学会摘要与程序，第26卷，第3期，1994年，第27页。O N.R.O‘Brien和S.Pietraszek-Mattner，《层状细粒冰湖堆积物的组构起源》，《沉积研究杂志》，第68卷，1998年，第832-840页。

Interdisciplinary (99)This proposal addresses two weaknesses in undergraduate science education. 1) Traditional education in the natural sciences suffers from a lack of interdisciplinary linkages. This proposal seeks to enhance interdisciplinary education in the natural sciences at Bloomsburg University through the addition of new courses and new laboratory exercises utilizing Scanning Electron Microscopy (SEM) as part of a new, multidisciplinary program in Environmental Sciences. 2) An interdisciplinary program of Marine Science is already taught at the Wallops Island Marine Science Center (WIMSC), of which Bloomsburg University is a member. This center is a field station for summer courses and student and faculty research, but as a traditional field station, it lacks sophisticated analytical equipment. The addition of a SEM will provide a unique opportunity to employ analytical techniques in a field setting. This proposal requests funds for the purchase of a compact model of SEM that will be used on the Bloomsburg campus during the academic year for laboratory exercises in the new Environmental Sciences curriculum, as well as for labs in other courses in the Biology and Geology curricula, and for student research. During the summer months, the machine will be used at the WIMSC, primarily for instruction in the multidisciplinary Marine Science curriculum. The SEM is a logical choice for this curricular innovation because of its successful incorporation in undergraduate education in a variety of disciplines. The ways that the SEM is being used in the classroom and field has been influenced by: o L. S.
