Abstract

The rapid spreading of broadband Internet access is enabling new methods of delivery for modern engineering and science curricula. This paper describes the design and implementation of a remote laboratory architecture, which allows the execution of experiments in real time. Contrary to previous remote-laboratory implementations based on a batch mode of operation, in this new system the students can interactively control the experiments and obtain the corresponding outputs (including raw data, data plots, video/audio streams and recordings) in an integrated browser-based user interface. Furthermore, this real-time system was designed in a platform-independent fashion such that it will facilitate its expansion beyond the boundaries of the original institution. A mechanical vibration setup is used to illustrate the system capabilities.

1. Introduction

Real experiments are indispensable in engineering and science education for developing skills for dealing with physical processes and instrumentation. The traditional way of conducting educational experiment is to go to a laboratory facility, where the experimental setups are located. There, the students typically work in groups (or sometimes individually) at a particular laboratory exercise and may receive tutorial help from instructors present at the site.1 During the last decade or so, Stevens Institute of Technology (SIT)2,3,4 as well as many other colleges and universities5 all around the world have begun to use Web-based remote laboratories. This trend of integrating such remote laboratories into undergraduate curricula is also supported by university administrators. A factor in support of this trend is the fact that physical experiments are expensive to maintain require dedicated facilities to accommodate the experimental setups. The rapid growth of the student populations in many institutions puts additional burdens on the spatial, temporal, financial and human resources required for operating traditional laboratories. On the other hand, due to the rapid increase available bandwidth of Internet, the materials that can be transferred on the network are no longer limited to static text accompanied by some static graphical images but can also include live or recorded audio and video content.6 The use of hypertext, hypermedia and multimedia in Web applications can potentially provide exciting and engaging learning environments, which will then lead to significant changes in the design of pedagogical processes and instructional approaches. Also, recently some evidence has started to be reported that Web-based remote laboratories can complement or even replace on-hand laboratories without compromising the desired learning outcomes.7

The results of a recent study8 showed that the interface of remote laboratories based on the batch mode of operation fail to provide the students a feeling of actual presence. The students felt somewhat disconnected from the remotely located experimental apparatus using, yet they liked the general convenience provided by remote laboratories and the ability to carry out the
