Engineering - Chemical (53)Our work addresses the fundamental national needs of engineering student retention because it provides a project/inquiry -based experience for first year engineering students who have not yet committed to engineering. To address this need we have created a comprehensive, web-integrated, learning and student assessment module. This module is based on a feedback-controlled acid neutralization laboratory experiment. It has been designed for our first year engineering students and includes topics such as feedback control, which is of interest to many of the engineering disciplines. Our experiment also incorporates the use of mass conservation equations (of interest to chemical and environmental engineers) and modeling of engineering systems with computer - based simulation which is of interest to all engineers. A key part of our module was the development of a web-based student (Primary Trait Analysis) assessment tool. This assessment tool will be "wrapped around" the simulator so that instructors can "observe" and then provide feedback about how students go through the process of using a simulations tool to explore, understand, and interpret data from a physical experiment. From this, instructors would gain crucial insight into student learning pathways and thus determine both how, and how well students are learning. Further it endeavors to show how to integrate web-based information and the use of an engineering simulator to explore and understand a physical experiment. The details necessary to reproduce the experiment, the simulator, the web-based information and the assessment procedure are available for testing and implementation at other institutions.

工程-化学(53)我们的工作解决了国家对工程专业学生保留的基本需求，因为它为还没有致力于工程专业的一年级工程专业学生提供了一种基于项目/探究的体验。为了满足这一需求，我们创建了一个全面的、网络集成的学习和学生评估模块。本模块基于反馈控制的酸中和实验室实验。它是为我们一年级的工程学学生设计的，包括反馈控制等主题，这是许多工程学学科都感兴趣的。我们的实验还结合了质量守恒方程的使用(化学和环境工程师感兴趣的)和工程系统的建模与基于计算机的模拟，这是所有工程师感兴趣的。我们模块的一个关键部分是开发一个基于网络的学生(主要特质分析)评估工具。该评估工具将围绕在模拟器周围，以便教师可以对学生如何使用模拟工具探索、理解和解释物理实验数据的过程进行观察，然后提供反馈。从这一点上，教师将获得对学生学习途径的关键洞察，从而确定学生学习的方式和程度。此外，它还努力展示如何整合基于网络的信息，以及如何使用工程模拟器来探索和理解物理实验。复制实验、模拟器、基于网络的信息和评估程序所需的细节可供其他机构测试和实施。
