It is the intent of this project to help prepare scientifically literate citizens by improving the scientific education of non- science majors (with a specific focus on elementary education majors) enrolled in an introductory physics course (Physics 100). A Laboratory/Lecture format for this course is already in place which encourages students to learn physics first by doing experiments and then developing these concepts through lectures and discussions. To address the difficulty that many of these students are not particularly adept at using mathematics, the general pattern recognition required to move from the concrete experiment to the abstract principle is developed through graphing. This approach has been well accepted; however there are two difficulties: 1) graphing significant amounts of data can become tedious, causing students to become weary of the process and the science involved; and 2) gathering sufficient data to gain insight into systems through the use of the scientific method can be extremely time consuming. These two difficulties can be overcome by computerizing the laboratory. Data can be plotted and revised expeditiously using a computer. Using probes interfaced to the computer, significant amounts of data can be collected rapidly. These data can then be easily plotted. Thus, greater emphasis can be placed on the science with less energy expended on technical details. More time can be spent discerning the patterns of nature and exploring their implications.

该项目的目的是通过改善就读物理入门课程（物理 100）的非科学专业（特别关注基础教育专业）的科学教育，帮助培养具有科学素养的公民。 本课程的实验室/讲座形式已经到位，鼓励学生首先通过做实验来学习物理，然后通过讲座和讨论来发展这些概念。 为了解决许多学生不太擅长使用数学的困难，从具体实验转向抽象原理所需的一般模式识别是通过绘图来开发的。 这种方法已被广泛接受；然而，存在两个困难：1）绘制大量数据的图表可能会变得乏味，导致学生对这个过程和所涉及的科学感到厌倦； 2）通过使用科学方法收集足够的数据来深入了解系统可能非常耗时。 这两个困难可以通过实验室计算机化来克服。 可以使用计算机快速绘制和修改数据。 使用与计算机连接的探头，可以快速收集大量数据。 然后可以轻松绘制这些数据。 因此，可以将更多的重点放在科学上，而在技术细节上花费更少的精力。 可以花更多的时间来辨别自然的模式并探索其含义。
