Using Computer-Based Electronic Probes to Introduce Studentsto Research in Physiology

这个项目通过让生理学学生参与实验项目，使用基于计算机的仪器来解决他们提出的关于动物系统的问题，从而向他们介绍研究性学习。在专业生理学和神经生理学入门课程以及非专业生理学入门课程中，学生使用一系列计算机接口传感器和电极来测量和分析各种生理过程，从动作电位到脑电波。学生们在协作小组中与教师密切协商，使用基于计算机的指导来建立和完成生理学重点研究的各个阶段。这些包括在网上和实验室图书馆搜索文献，提出问题，学习实验设计的基本知识，记录硬件，以图形格式简化和描述结果，进行适当的统计测试，以及以口头和书面形式得出合理的结论。这个实验项目使学生能够提出关于生理系统的原创性问题，并获得一些解决问题的策略和技能。由于这些经历，学生不仅获得了对生理过程动态的实际和亲密的欣赏，而且还获得了在其他场合（如荣誉项目、研究生学习和专业就业）遇到新问题时的计算技能。

This project introduces physiology students to investigative learning by engaging them in experimental projects that use computer-based instruments to solve problems that they pose about animal systems. In the introductory physiology and neurophysiology courses for majors, and in the introductory physiology course for nonmajors, students use an array of computer-interfaced transducers and electrodes to measure and analyze a variety of physiological processes, ranging from action potentials to brain waves. Consulting closely with the instructor, students in collaborative teams use computer-based guides to set up and work through the phases of a focused study in physiology. These include searching the literature on-line and in the lab library, posing questions, learning the rudiments of experimental design, logging hardware, reducing and depicting results in graphic formats, performing appropriate statistical tests, and developing reasoned conclusions in oral and written form. This laboratory project enables students to raise original questions about physiological systems and to acquire some of the problem-solving strategies and skills needed to answer them. As a result of these experiences, students not only gain a practical and intimate appreciation of the dynamics of physiological processes but also acquire computational skills for pursuing new problems they will encounter in other venues, such as honors projects, graduate studies, and professional employment.
