Development of an Interactive Tutorial on Statistical Design and Analysis of Experiments

一个来自化学工程系、数学系和课程与教学系的跨学科团队正在设计和创建一个交互式的、基于互联网的教程资源，教化学工程系的学生如何统计地设计和分析实验。该教程是在开发过程中与正在进行的测试和评估合作制作的。本教程包含四个独立的信息模块，涵盖随机化、块化、析因设计和回归建模。第五个模块包含两个在线案例研究，学生可以通过这些案例研究来更全面地测试他们对概念的理解。化学工程专业的学生正在测试这种产品，测试结果将根据美国评估协会（American Evaluation Association）发布的指导方针进行评估。结果正在全国传播。

Interdisciplinary (99)An interdisciplinary team from the Departments of Chemical Engineering, Mathematics, and Curriculum and Instruction is designing and creating an interactive, Internet-based tutorial resource that is teaching chemical engineering students how to statistically design and analyze experiments. The tutorial is being collaboratively produced with ongoing testing and evaluation during the developmental process. The tutorial contains four standalone informational modules covering randomization, blocking, factorial designs, and regression modeling. A fifth module contains two on-line case studies that the students may work through to more fully test their comprehension of the concepts. Chemical Engineering students are testing the product, and the results are being evaluated based on the guidelines published by the American Evaluation Association. The outcomes are being disseminated nationally.
