Equipment for Improving Undergraduate Instruction in Physiology

该项目的目标是升级两门课程的生理学实验室：解剖学和生理学，以及脊椎动物生理学。首先，为现有的桑顿生理记录仪购置了一个双通道记录仪辅助换能器和前置放大器，并用固态电子学更新了现有的生理记录仪，从而引入了两个新的实验室：一个心血管健身实验室和一个生物反馈实验室；减少了实验室小组的规模，从而为学生提供了更好的动手体验机会：以及取代了演示实验，允许小组学生在四个不同的实验室测量肺容量、EEG、EKG和容量脉搏等功能。其次，TRIAC离心机可以旋转微量血球、尿液和血管，使学生能够在肾脏生理学实验室首次测定红细胞压积并进行尿液分析程序。第三，将电视视频系统引入八个具有组织学组成部分的实验室，改善了教学和学生对致力于微结构教学的实验室的使用。最后，新的蒸馏器提供生理解决方案所需的蒸馏水。上述发展鼓励实验，培养学生对生理原理的理解，挑战学生的分析思维，并鼓励妇女的技术能力，包括参加该学院为弱势学生设立的“希尔学院”计划的大量老年少数民族妇女。接受资助的机构正在将NSF的奖励与从非联邦来源获得的同等金额相匹配。

The goal of this project is to upgrade the physiology laboratories of two courses: Anatomy and Physiology, and Vertebrate Physiology. First, the acquisition of a dual channel recorder accessory transducers and preamplifiers for the existing Thornton physiographs, and the updating of existing physiographs with solid state electronics are resulting in the introduction of two new labs: a Cardiovascular Fitness lab and a Biofeedback lab; the reduction of lab group size, thus providing students with better opportunity for hands- on-experience: and the replacement of demonstration experiments allowing small groups of students to measure such functions as lung volume, EEG's, EKG's and volume pulse measurements in four different laboratories. Secondly, a TRIAC centrifuge which spins microhematocrits, urine and blood tubes allows students to determine hematocrit for the first time and to perform urinalysis procedures in the Kidney Physiology lab. Thirdly, a T.V. videosystem introduced into eight labs having a Histology component is improving teaching and student use of labs dedicated to the teaching of microstructure. Lastly, a new still provides needed distilled water for physiological solutions. The above developments encourage experimentation, foster students' understanding of physiological principles, challenge students to think analytically, and encourage technical competence of women, including large numbers of older minority women who are enrolled in the college's "Hill College" program for disadvantaged students. The grantee institution is matching the NSF award with an equal sum obtained from non-Federal sources.
