This project employs the unifying approach of the new materials synthesis and processing curriculum in the Materials Science and Engineering (MSE) Program to the laboratory setting. The curriculum is based on the innovations in the content and pedagogy of materials science instruction as reported by The Materials Research Society, the American Society of Engineering Education, the NSF Undergraduate Materials Education Workshop, and The Metallurgical Society. The new curriculum provides a core for the study of all classes of engineered materials. The four elements of this core - microstructure, properties, processing and performance - comprise the adaptation of the holistic approach to the study of materials science and engineering. Strong emphasis on materials synthesis and processing is a special feature of the new curriculum, a key component of which is the intensive junior-level laboratory course. The adaptation of the holistic approach to materials processing is completed by the inclusion of polymer processing equipment in the laboratory which, heretofore, had limited capabilities. This laboratory now includes the examination of processing induced orientation effects on polymer properties. The high degree of molecular alignment that can be achieved in polymers and the associated limitations in shaping capabilities are typical of the microstructure-processing interactions at the core of the new curriculum. The hands-on lab course cuts across the materials classes, stressing central microstructural phenomena and their interactions with shaping and treating operations. The project enhances undergraduate materials design experiences throughout the engineering curriculum and reinforces the educational goal of connecting course material with industrial practice.

该项目采用材料科学与工程(MSE)计划中新材料合成与加工课程的统一方法来设置实验室。该课程基于材料研究学会、美国工程教育学会、NSF本科生材料教育研讨会和冶金学会在材料科学教学内容和教学方法方面的创新。新课程为所有类别的工程材料的学习提供了核心。这个核心的四个要素--微观结构、性能、加工和性能--构成了对材料科学和工程研究的整体方法的适应。强调材料合成和加工是新课程的一个特点，其中一个关键组成部分是初级强化实验课程。对材料加工的整体方法的适应是通过在实验室中包括聚合物加工设备来完成的，在此之前，这些设备的能力有限。该实验室现在包括研究加工诱导取向对聚合物性能的影响。在聚合物中可以实现的高度分子排列和成型能力的相关限制是新课程核心的微结构-加工交互作用的典型表现。动手实验课程跨越材料课程，强调中心微结构现象及其与成形和处理操作的相互作用。该项目在整个工程课程中加强了本科生的材料设计经验，并强化了将课程材料与工业实践联系起来的教育目标。
