This project enables faculty to design laboratories in an introductory environmental science class that raise the scientific literacy of students with little or no scientific background through applying the pedagogy of learning. New equipment supports the creation of four laboratory exercises. These exercises are designed so that students apply the scientific method using recently developed data collection technology and computer software. The laboratory exercise sequence starts students at a relatively low conceptual level at which learning occurs through manipulating physical objects to observe cause and effect relationships. It concludes with a sampling exercise that involves students with a more intellectually sophisticated level of conceptual and analytical thought. The emphasis placed on intellectual development in this series of laboratory exercises is unique and highly useful in developing scientific literacy. The new equipment introduces scientifically illiterate students to (1) cause and effect relationships in science through the use of a ground water model and computer simulations that allow students to manipulate variables and watch the results, (2) methods of collecting and analyzing data that range from qualitative observations to the use of state-of-the-art environmental sensors and computers, and (3) effective communication of their discoveries and excitement in a written and mathematical form.

该项目使教师能够在环境科学入门课程中设计实验室，通过应用学习教育学来提高几乎没有科学背景的学生的科学素养。新设备支持创建四个实验室练习。这些练习的设计是为了让学生使用最新开发的数据收集技术和计算机软件来应用科学方法。实验室练习序列从相对较低的概念水平开始，通过操纵物理对象观察因果关系来进行学习。它以一个抽样练习结束，让拥有更复杂的概念和分析思维水平的学生参与进来。在这一系列实验室练习中，对智力发展的强调是独特的，对培养科学素养非常有用。新设备向不懂科学的学生介绍(1)通过使用地下水模型和计算机模拟，允许学生操纵变量并观察结果，(2)收集和分析数据的方法，从定性观察到最先进的环境传感器和计算机的使用，以及(3)以书面和数学形式有效地交流他们的发现和兴奋。
