9455705 Bedard This project pioneers a new way to provide experimental complements to theoretical courses. The goal is to train students to use what they learn to examine all that they see and as a result, to question. The fundamental idea is to create a suite of simple experiments which can be done in the home and assigned like homework problems. Such simple, but elegant experiments are dubbed Hands-On-Homework (HOH) which: * encourages students to use engineering theory to explain everyday phenomena, and to compare their observations to theoretical prediction; * provides open-ended opportunities to explore engineering questions using readily available materials and familiar experiences; * trains students to conduct "reality checks" and naturally apply theoretical analysis to experimental observations; and * provides continuous opportunities for students to empirically explore engineering questions throughout their college careers and develop habits contpibuting to life long learning. This project is tied to curriculum changes planned for the new Integrated Teaching Laboratory. Hands-On Homework is liberally sprinkled throughout the entire curriculum, primarily in the first three years, including introductory mathematics and physics courses. Initial disciplinary courses such as statics, dynamics, thermodynamics, and circuits benefit, as well as more advanced courses such as fluid mechanics, heat transfer, control theory, or materials. HOH problems are piloted in two courses while doing an outreach to identify further courses. Evaluation is done by holding consensus groups during the semester and comparing performance of students with and without HOH. Results will be presented at meetings and reviews. Ultimately, a user's guide will be produced containing all the Hands-On-Homeworks as well as the performance evaluations. Because HOH's are low-cost, they can be easily rep- licated and the results of the project widely exported.

9455705 Bedard该项目开创了一种新的方式，提供实验补充理论课程。目标是训练学生用他们所学的东西来检查他们所看到的一切，并因此提出质疑。基本的想法是创建一套简单的实验，可以在家里完成，并像家庭作业一样分配问题。这种简单而优雅的实验被称为动手作业（HOH），它：* 鼓励学生使用工程理论来解释日常现象，并将他们的观察结果与理论预测进行比较; * 提供开放式的机会，利用现成的材料和熟悉的经验来探索工程问题;* 训练学生进行“现实检查”，并自然地将理论分析应用于实验观察;和 * 为学生提供持续的机会，在他们的大学生涯中以经验探索工程问题，并培养终身习惯学习 该项目与新的综合教学实验室计划的课程改革有关。动手作业是自由地洒在整个课程，主要是在前三年，包括入门数学和物理课程。初级学科课程，如静力学，动力学，热力学和电路受益，以及更先进的课程，如流体力学，传热学，控制理论或材料。 HOH问题在两个课程中进行试点，同时进行推广以确定进一步的课程。评估是通过在学期中举行共识小组，并比较学生的表现与没有HOH。结果将在会议和审查中提出。最后，将编制一份用户指南，其中载有所有的家庭作业和成绩评价。 由于HOH的成本低，它们可以很容易地复制和项目的结果广泛出口。
