Equipment for Improving Undergraduate Instruction in Physiology

本计画的目标是提升解剖生理学和脊椎动物生理学两门课程的生理学实验室。首先，为现有的桑顿生理仪购买了双通道记录仪附属传感器和前置放大器，并使用固态电子设备更新了现有的生理仪，从而引入了两个新实验室：心血管健康实验室和生物反馈实验室；减少实验小组的规模，从而为学生提供更好的实践机会；以及替换示范实验，允许学生小组在四个不同的实验室测量肺容量、脑电图、心电图和体积脉搏等功能。其次，TRIAC离心机旋转微血细胞比容、尿液和血管，让学生第一次确定红细胞比容，并在肾脏生理学实验室进行尿液分析程序。第三，将电视录像系统引入具有组织学成分的八个实验室，提高了教学和学生对微观结构教学实验室的使用。最后，一个新的蒸馏器提供生理溶液所需的蒸馏水。上述发展鼓励实验，培养学生对生理原理的理解，挑战学生的分析性思考，并鼓励女性的技术能力，包括大量的老年少数民族女性，她们参加了学院的“希尔学院”项目，为弱势学生服务。受资助机构将从非联邦来源获得等额的NSF奖励。

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.
