Workstations for the Undergraduate Physiology of Exercise Laboratory

小行星9351841 现代化教学设备的获取和独特配置将扩大和加强学生在北方爱荷华州大学运动实验室的本科生理学的经验，从而对基本的人类生理学原理有更高的理解。该建议的设计有两个方面：a）通过个体化和小组调查促进学生的主动学习，以及B）提供仪器，使学生能够学习用当前设备无法调查的几个基本运动生理学原理。在这一要求的主要仪器，代谢测量系统与几个可用的选项，和五个联网的个人计算机工作站，将促进学生更积极的学习相比，传统的演示在运动生理学实验室。 外围工作站的配置将提供一个“动手”的方法来理解运动生理学，允许观察和调查的实验室问题，由个人或小组的学生无论是在预定的实验室或课外项目。此外，代谢测量系统将为我们的学生提供经验，而不是通常在本科实验室检查，但不可或缺的运动生理学的研究。具体来说，学生将能够测试运动对心肌功能和动脉血氧饱和度的影响，并研究随着运动强度的变化，能量代谢的实时变化。此外，代谢测量的灵敏度和精确度将从本系统得到改善。实验室的改进将促进学习过程中直接解决问题的方法，并反映在学生对科学原理、概念和方法的理解的提高上。 ***

9351841 Kolkhorst The acquisition and unique configuration of modern instructional equipment will expand and strengthen the students' experience in the undergraduate physiology of exercise laboratory at the University of Northern Iowa resulting in a higher order of understanding of basic human physiological principles. The design of this proposal is two- fold: a) to promote active learning by the students through individualized and small group investigation and b) to provide instrumentation enabling students to study several fundamental exercise physiology principles that cannot be investigated with the current equipment. The primary instruments in this request, a metabolic measurement system with several available options, and five networked personal computer work stations, will facilitate more active learning by students as compared to traditional presentations in exercise physiology laboratories. The configuration of the peripheral work stations will provide for a "hands-on" approach to understanding exercise physiology by allowing for the observation and investigation of laboratory problems by an individual or small groups of students either in scheduled laboratories or out-of-class projects. Also, the metabolic measurement system will provide experiences for our students not normally examined in an undergraduate laboratory but integral to the study of exercise physiology. Specifically, students will be able to test the effects of exercise on myocardial function and arterial oxygen saturation as well as investigate real-time changes in energy metabolism as exercise intensity is varied. Furthermore, sensitivity and precision of metabolic measurements will be improved from the present system. The enhancements in the laboratory will foster a direct problem-solving approach to the learning process and be reflected in the students' increased comprehension of scientific principles, concepts, and methods. ***
