This project involves development of 24 new or revised experiments to inject significant elements of investigation and discovery into introductory physics laboratories. The project is using automatic data acquisition and analysis. Students are being guided through a series of explorations of the applicability of simple models for describing the phenomena under study. Computer-assisted data collection is allowing students to quickly alter initial and boundary conditions to get a broad overview of the validity of a model. The accuracy and precision of the data is allowing students to observe systematic departures of the observations from the predictions of a simple model. The students are encouraged to develop more sophisticated models to account for the observed discrepancies and to create a plan for subjecting those models to a test. The exercises are being packaged in electronic format using a Computer-based Instructional Development (CID) tool. This format is designed to allow students to find within the CID shell text, video, audio, and graphics materials that will serve as resources for how their equipment and programs function, and as a collection of queries and hints that will help in synthesis and discovery activities.

该项目涉及开发24个新的或修订的实验，为入门物理实验室注入重要的调查和发现元素。 该项目正在使用自动数据采集和分析。学生们正在通过一系列的探索简单的模型来描述所研究的现象的适用性。计算机辅助数据收集允许学生快速改变初始和边界条件，以获得模型有效性的广泛概述。数据的准确性和精确性使学生能够观察到观察结果与简单模型预测的系统偏差。鼓励学生开发更复杂的模型来解释观察到的差异，并制定一个计划来测试这些模型。 这些练习正在利用计算机辅助教学开发工具以电子格式打包。 这种格式的目的是让学生在CID外壳中找到文本，视频，音频和图形材料，这些材料将作为他们的设备和程序如何运行的资源，并作为查询和提示的集合，这将有助于综合和发现活动。
