Introduction of Enhanced Technologies for the Experimentally Based Laboratory Study of Animal Systems

9452613 Toll本项目通过向本科生介绍动物系统研究中的现代实验研究技术和方法，支持最近的生物学课程改革。为了改进生理学的实验室教学，学生将使用配备硬件/软件接口、换能器和信号调节器的麦金塔电脑作为虚拟示波器和图表记录器。基于这些技术的实验将包括呼吸、循环、肌肉和神经系统的生理研究。学生将在发育生物学中使用显微外科移植和显微注射技术，直接研究原口动物和后口动物的细胞分化和器官发生的控制。利用这些新技术，学生将首先掌握新技术，然后鼓励他们设计行为，并分析他们自己的实验程序的结果。这些现代化的实验室经验将纳入1994年秋季实施的新的生物学课程，内容如下：所有主修和非主修的学生都必须在第一年修一门课程；本专业必修的第二学期生物学导论；两门高级生物学课程。新课程的核心是实验和原创、创造性的研究，所有二年级生物专业的学生都要参加以实验室为基础的研究方法课程，为高级课程做准备。

9452613 Toll This project is supports recent curricular reform in biology by introducing undergraduate students to modern, experimental research technologies and techniques in the study of animal systems. In improvements to laboratory instruction of physiology, students will use Macintosh computers, fitted with hardware/software interfaces, transducers, and signal conditioners, to function as virtual oscilloscopes and chart recorders. Experiments based on these technologies will encompass physiological study of the respiratory, circulatory, muscular and nervous systems. Students will use microsurgical transplantation and microinjection technologies in developmental biology, directed toward the study of controls of cytodifferentiation and organogenesis in both protostomes and deuterostomes. With the benefit of these new technologies, students will first master the new techniques and then will be encouraged to design conduct, and analyze the results of their own experimental procedures. These modernized laboratory experiences will be incorporated in the new biology curriculum for implementation in the fall of 1994 as follows: one first-year course required of all students, both majors and non-majors; the second semester of introductory biology required of majors; two upper-level courses in biology. The new curriculum has at its core, experimentation and original, creative research, with all second-year biology majors taking a laboratory-based research methods course in preparation for advanced classes.
