A multimedia-based title and curricular plan that supports learning about DC motors across a range of learning stages will be designed, developed, and assessed. The multimedia piece will be called Motor Workshop. Prospective users range from freshman physics students to masters-level engineering students. The subject matter will be sub-fractional horsepower DC electric motors. This subject is relevant in a variety of technological fields including physics students learning about electricity and magnetism, electrical engineers learning about circuit analysis and design, and mechanical designers seeking the proper motor to drive a particular device. We have begun working with the instructors of the Stanford courses that introduce engineering undergraduate students to DC motor to define the learning objectives related to motors in their particular course. All are enthusiastic about the prospect of enhanced materials being available to them and their students on motors. The next step in our work with the course instructors is to develop a preliminary curricular plan. The resulting understanding of the particular needs of the various courses and a vision of how multimedia-based curriculum might be used in each course will in large part form the basis for designing and developing the multimedia title. Other major sources of input during this planning phase will be recent work in the Education, Human Computer Interface Design, and Cognitive Science communities. The resulting software title, Motor Workshop, will be a comprehensive and scaffolded information resource pertaining to all aspects of small, DC motors. By scaffolded we mean that concepts will be presented in a graduated manner so that they build in depth and complexity. The architecture of Motor Workshop will allow a more mature student to enter at a more advanced level, but will allow her to return to more basic materials if she finds the need for review. Motor Workshop will include terminology and first principles of physics which will explicate the basic function of motors, concepts of torque, speed and power, issues of circuit design, explanations of the basic function of motors and circuit design, determination of critical motor specifications and the choice of a motor based on these data, and recommended subclasses of motors for particular applications, possibly with catalog data embedded into the software. Motor Workshop will be developed with input from the core instructors at Stanford University. In addition, it will be distributed to engineering faculty at Arizona State University (Prof. D. Evans) and University of Texas (Prof. K. Wood) for them to evaluate its portability to other institutions. Using a variety of assessment techniques that we have had experience with, including pre- and post-test performance comparisons, questionnaires and videotaped observation (VIA), we will attempt to prove our hypothesis that computer-based information resources can be developed which will have a positive effect on the learning environment of a wide developmental range of students. This is not the first multimedia title that this group has created. Three other titles (Bicycle Dissection, The Electric Drill Stack, Linkages) were developed in order to enhance the resources and points of view scripted into the curriculum. These title are consistently being used in our undergraduate curriculum. The proposed DC motor title will built upon the lessons we learned from assessing students working with Bicycle Dissection, The Electric Drill Stack, Linkages over the last two years.

将设计、开发和评估基于多媒体的标题和课程计划，支持在一系列学习阶段学习直流电机。 该多媒体作品将被称为“汽车工作室”。 潜在用户范围从新生物理学生到硕士级工程学生。 主题将是次小马力直流电动机。 该学科与各种技术领域相关，包括物理学生学习电和磁、电气工程师学习电路分析和设计，以及机械设计师寻求合适的电机来驱动特定设备。 我们已经开始与斯坦福大学课程的讲师合作，向工程本科生介绍直流电机，以确定其特定课程中与电机相关的学习目标。 所有人都对为他们和他们的学生提供有关电机的增强材料的前景充满热情。 我们与课程讲师合作的下一步是制定初步的课程计划。 由此产生的对各种课程的特殊需求的理解以及如何在每门课程中使用基于多媒体的课程的愿景将在很大程度上构成设计和开发多媒体标题的基础。 此规划阶段的其他主要投入来源将是教育、人机界面设计和认知科学社区的最新工作。 由此产生的软件名称“Motor Workshop”将成为与小型直流电机各个方面相关的综合性支架信息资源。所谓“脚手架”，是指概念将以渐进的方式呈现，以便它们具有深度和复​​杂性。 汽车工作室的架构将允许更成熟的学生进入更高级的水平，但如果她发现需要复习，将允许她返回到更基本的材料。电机研讨会将包括术语和物理第一原理，其中将解释电机的基本功能、扭矩、速度和功率的概念、电路设计问题、电机基本功能和电路设计的解释、关键电机规格的确定和基于这些数据的电机选择，以及针对特定应用推荐的电机子类，可能还会将目录数据嵌入到软件中。 Motor Workshop 将根据斯坦福大学核心讲师的意见进行开发。此外，它将分发给亚利桑那州立大学（D. Evans 教授）和德克萨斯大学（K. Wood 教授）的工程系教师，供他们评估其向其他机构的可移植性。 我们将利用我们经验丰富的各种评估技术，包括测试前和测试后的表现比较、问卷调查和录像观察（VIA），尝试证明我们的假设，即可以开发基于计算机的信息资源，这将对广泛发展的学生的学习环境产生积极影响。 这并不是该小组创建的第一个多媒体作品。开发了其他三个标题（《自行车解剖》、《电钻堆栈》、《连杆》），以增强课程中的资源和观点。这些名称一直在我们的本科课程中使用。拟议的直流电机标题将建立在我们过去两年对从事自行车解剖、电钻组、连杆工作的学生进行评估所获得的经验教训的基础上。
