Design and Development of an Internet Based Physical Laboratory Course within an Undergraduate Program

工程-工程技术（58）本项目是为工程技术学生设计和开发一个基于互联网的介绍性数字电子实验室。该项目使用基于互联网的设施，实验室实验、制造过程和工业设备可用于操作和控制。远程学习的“动手”实验室为学生提供了更像传统实验室的体验，并且优于模拟技术。该项目正在确定基本的入门电子数字实验室实验，这些实验正在重新配置为五个独立的模块，用于远程控制的在线交付。正在开发的模块包括逻辑电路和门；半加法器、全加法器、计数器、移位寄存器的设计与开发；并设计数字电路。可同时访问多个实验。为了实现这一目标，项目团队正在创建一个合适的电子平台，该平台将容纳电子实验室组件，交换机制和PC之间的接口系统，图形用户界面（GUI），以及在GUI和Internet之间进行交互的基于java的软件模块。这种方法为其他研究人员提供了一种方法论，他们可以据此创建远程互联网实验室。学生学习的评估是通过比较传统实验室和远程实验室的学生来进行的。该系统软件接口的性质使得通过URL链接访问现有的商业课程提供系统成为可能。这些材料正在通过一个在整个项目期间维持的网站传播。

Engineering-Engineering Technology (58) The project is designing and developing an Internet based introductory digital electronics laboratory for engineering technology students. The project is using an Internet based facility where laboratory experiments, manufacturing processes, and industrial equipment are available for operation and control. The "hands-on" laboratory for distance learning provides students with an experience that is more like a traditional laboratory and is superior to simulation techniques. The project is identifying essential introductory electronics digital laboratory experiments that are being reconfigured into five independent modules for an on-line delivery that is remotely controlled. Modules that are being developed include logic circuits and gates; design and development of half-adder, full-adder, counter, and shift register; and design of digital circuits. Multiple experiments can be simultaneously accessed. To accomplish this goal, the project team is creating a suitable electronic platform that will hold electronic laboratory components, an interfacing system between the switching mechanism and a PC, a graphical user interface (GUI), and a Java-based software module that interacts between the GUI and the Internet. This approach is providing other investigators with a methodology that they can adapt to create remote Internet laboratories. Assessment of student learning is being conducted by comparing students who take the traditional laboratory and the students who take this remote laboratory. The nature of the software interface of the system is making it feasible to access existing commercially available course offering systems through URL links. The material is being disseminated through a website that is being maintained throughout the project.
