Development and Assessment of Multimedia for "Motor Workshop"

一个基于多媒体的标题和课程计划，支持学习直流电机在一系列的学习阶段将被设计，开发和评估。 多媒体作品将被称为汽车车间。 潜在的用户范围从大一物理学生到硕士水平的工程学生。 主题将是次分马力直流电动机。 这门课与各种技术领域有关，包括物理学学生学习电和磁，电气工程师学习电路分析和设计，以及机械设计师寻找合适的电机来驱动特定设备。 我们已经开始与斯坦福大学的导师合作，向工程本科生介绍直流电机，以确定与电机相关的学习目标。 所有人都对他们和他们的学生在发动机上使用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一个初步的课程计划。 由此对各种课程的特殊需要的了解以及对如何在每门课程中使用多媒体课程的设想，将在很大程度上构成设计和开发多媒体教材的基础。 在此规划阶段的其他主要输入来源将是最近在教育，人机界面设计和认知科学界的工作。 由此产生的软件标题，电机车间，将是一个全面的和脚手架的信息资源有关的各个方面的小型直流电机。我们所说的脚手架是指概念将以渐进的方式呈现，以便它们建立在深度和复杂性上。 电机车间的架构将允许一个更成熟的学生进入一个更先进的水平，但将允许她返回到更基本的材料，如果她发现需要审查。电机研讨会将包括术语和物理学的第一原理，将解释电机的基本功能，扭矩，速度和功率的概念，电路设计的问题，电机和电路设计的基本功能的解释，关键电机规格的确定和基于这些数据的电机选择，以及推荐的电机子类，用于特定应用。可能具有嵌入到软件中的目录数据。 电机研讨会将与斯坦福大学的核心讲师的投入开发。此外，它还将分发给亚利桑那州立大学的工程学院（教授D。Evans）和德克萨斯大学（K. Wood），以便他们评估其对其他机构的可移植性。 使用各种各样的评估技术，我们已经有经验，包括测试前和测试后的性能比较，问卷调查和录像观察（VIA），我们将试图证明我们的假设，基于计算机的信息资源可以开发，这将有积极的影响，广泛的发展范围内的学生的学习环境。 这并不是这个小组创建的第一个多媒体标题。另外三个标题（自行车解剖，电钻堆栈，联动）的开发，以加强资源和观点脚本到课程。这些标题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从评估学生与自行车解剖，电钻栈，链接在过去两年的工作经验教训。

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.
