Instrumentation to Enhance Instruction and Undergraduate Research in Plant Physiology and Ecology

获得稳态气孔仪、便携式叶面积计、便携式光合作用系统以及这些仪器的附件和便携式计算机，将使学生有机会利用最先进的仪器来测量和分析一年级、三年级、以及高级实验室课程，旨在教授植物生理和生态学原理，以及加强植物科学的本科生研究项目。实验的设计是为了让学生使用新的仪器来测量在实验室和田间各种不同环境条件下生长的一些不同植物的蒸腾作用、叶面积和光合作用。在每个实验中，仪器将为学生提供一种方法，通过它可以：(1)阐述和测试与重要的生理和生态概念有关的假设；(2)获得最先进的设备的实践经验；(3)进行强化重要的生理和生态原理的实验；(4)研究合理的实验设计方法；(5)获得收集、分析和解释科学数据的第一手经验；(6)以科学期刊的形式报告实验。

The acquisition of a steady state porometer, portable leaf area meter, portable photosynthesis system, and accessories for these instruments plus a portable computer will provide the students with an opportunity to utilize state-of-the-art instrumentation to measure and analyze growth, productivity, and photosynthesis data in freshman, junior, and senior laboratory courses designed to teach plant physiological and ecological principles as well as enhance undergraduate research projects in the plant sciences. Experiments are designed so that students use the new instrumentation to make transpiration, leaf area, and photosynthetic measurements on a number of different plants grown under a variety of different environmental conditions in both the laboratory and field. In each experiment the instrumentation will provide a means by which students can: (1) formulate and test hypotheses related to important physiological and ecological concepts; (2) gain hands-on experience with state-of-the-art equipment; (3) conduct experimentation which reinforces important physiological and ecological principles; (4) examine the proper methods of experimental design; (5) gain first-hand experience in the collection, analysis, and interpretation of scientific data; and (6) report on the experimentation in a scientific journal format.
