This award contributes funds to the Department of Animal Ecology at Iowa State University to provide Modern instrumentation and technology which will improve instruction for undergraduate majors in their principal laboratory course in aquatic ecology. (1) Microvideo technology will be used to do a more effective job of teaching students how to study microscopic organisms, how to make quantitative measurements of plankton populations, and how to use scales and otoliths for aging fish. The major instrumentation to be purchased includes a microscope equipped with a color video camera, a VCR, and a color video monitor. (2) Students will be introduced to the concept and use of instruments interfaced with computers. As an example one procedure will use an electronic digitization board linked to a computer for measurements of lake morphometry and for calculating growth rates of fish from measurements of annual marks on hard parts of fish. (3) Students will gain experience in using microcomputer techniques for analyzing and presenting limnological and fisheries data. A statistical package combined with a microcomputer will be used to increase the efficiency of exercises on data processing, analysis, and presentation. The grantee is matching this award with non- Federal sources.

该奖项向爱荷华州立大学动物生态学系提供资金，以提供现代仪器和技术，这将改善本科生专业水生生态学主要实验室课程的教学。 （1）利用微视频技术，更有效地教授学生如何研究微生物、如何对浮游生物种群进行定量测量、如何利用鳞片和耳石进行老化鱼类等。 要购买的主要仪器包括配备彩色摄像机的显微镜、录像机和彩色视频监视器。 (2) 向学生介绍与计算机连接的仪器的概念和使用。 作为一个例子，一个程序将使用与计算机连接的电子数字化板来测量湖泊形态，并通过测量鱼的坚硬部分的年度标记来计算鱼的生长率。 (3) 学生将获得使用微计算机技术分析和呈现湖泊学和渔业数据的经验。 统计包与微型计算机相结合，可提高数据处理、分析和演示的练习效率。 受资助者将该奖项与非联邦来源相匹配。
