Promoting Investigative Learning in Biology Laboratories Using Computer-Based Data Acquisition Systems

丹尼尔·乌多维奇应在俄勒冈州尤金1995财年购买9551950 U尤金39,083美元，或97403 ILI-仪器项目：生命科学标题：在生物实验室中使用基于计算机的数据采集系统促进研究性学习教学实验室应该是课程的智力催化剂，学生在这里体验科学努力的各个方面，在那里，他们面临挑战，直面他们对自然世界的误解，在那里，他们学会构建解释和意义，而不是找到“正确”的答案。在许多本科生实验室中，用来收集数据的设备是学生学习和参与的障碍。通常，实验室协议迫使学生专注于数据收集的技术方面，而不强调所提出的基本科学原理。学生要有智力投入，就必须参与调查，也就是说，他们必须参与设计实验和解释结果。这项建议所要求的设备将有可能通过用计算机数据采集工具取代目前的模拟设备，如示波器和图表记录器，来加强学生在生物教学实验室的学习。为利用基于计算机的设备而设计的定制用户界面和课程材料的开发将：通过为学生提供快速分析数据的工具，强调批判性思维技能的使用；通过允许学生专注于重要的科学概念而不是工具本身，打破学习障碍；通过鼓励研究性实验室活动，弥合教学实验室经验和独立研究机会之间的差距。将购买必要的材料，为两个实验室(可容纳48-60名学生)配备电子数据采集和分析系统。这些设备将足够通用，可以在生物专业和非专业的各种课程中使用。

Daniel Udovic DUE 9551950 U of Oregon Eugene FY1995 $39,083 Eugene, OR 97403 ILI - Instrumentation Project: Life Sciences Title: Promoting Investigative Learning in Biology Laboratories Using Computer-Based Data Acquisition Systems Teaching labs should be the intellectual catalysts of a curriculum, where students experience all aspects of the scientific endeavor, where they are challenged to confront their misconceptions about the natural world, and where they learn to construct explanations and meaning rather than find the "right" answers. In many undergraduate labs the equipment used to collect data acts as a barrier to student learning and participation. Often laboratory protocols force students to focus on the technical aspects of data collection while de-emphasizes the underlying scientific principles being presented. To be intellectually involved student must participate in investigations, that is, they must be involved in the design of experiments and the interpretation of results. The equipment requested in this proposal will make it possible to enhance student learning in biology teaching labs by replacing current analog devices, such as oscilloscopes and chart recorders with computer-based tools for data acquisition. The development of customized user interfaces and curricular materials designed to take advantage of the computer-based equipment will: emphasize the use of critical thinking skills by giving students the tools to quickly analyze their data; break down obstacles to learning by allowing students to focus important scientific concepts rather than instrumentation per se; and bridge the gap between teaching lab experiences and independent research opportunities by encouraging investigative lab activities. Materials necessary to equip two lab rooms (serving 48-60 students) with systems for electronic data acquisition and analysis will be purchased. The equipment will be general enough to be used in a wide variety of courses serving both biology majors and non-majors.
