A Web-based Interactive Roadmap Facilitating Self-learning from CAD Modeling to Rapid Prototyping

Abstract

Conventional self-learning materials, such as textbook and presentation slides, provide a one- way and one dimensional information flow (i.e. from the first page to the last page). Interactive learning tools, such as computer programs, deliver a more encouraging learning environment, especially for the younger generation. Young students tend to be attracted to interactive web- based programs which facilitate two-way communication with multiple dimensions of information flows (i.e. cross-linked with various alternative paths). Furthermore, a gaming environment attracts the attention of young students and leads to more effective learning experiences. This paper proposes an innovative web-based application, the Interactive Roadmap, to provide an exciting learning environment for high school students, who are interested in engineering. The roadmap of a manufacturing project from Computer-Aided Design (CAD) modeling to Rapid Prototyping (RP) is developed for young students to gain knowledge and hands-on experiences in the field of manufacturing engineering. The interactive roadmap, presented as a treasure map, contains several training modules under the main topic. The modules are cross-linked to provide various alternative pathways for the students to explore the whole package in the way they choose. Students gain credits as they visit each stop and complete the associated quiz or assignment until they finish the whole package. Due to availability of resources, the prototype program being developed covers CAD modeling using SolidWorks 2007 and RP process using Dimension SST 768. The integration of CAD and RP is chosen for that they make a compact and self-contained system to demonstrate the concept of computer integrated manufacturing (CIM). The web-based program of the Interactive Roadmap is developed using PHP+MySQL with Flash, PowerPoint slides, and other multi-media files. With further development of training modules, the platform can also facilitate training in other topics.

Introduction

The objective of this research is to provide an encouraging learning environment for young students (i.e. high school, middle school), who are interested in engineering and willing to gain knowledge through self-explorations. This paper proposes a web-based program with an interactive roadmap to facilitate self-learning in the area of computer integrated manufacturing.

Online learning has become an important method for teaching various courses. It facilitates not only long-distance learning but also provides a new way of self-study. Conventionally, self- learning was performed mostly through reading. Textbooks and most reading materials play a passive role, which provides a bank of knowledge to those who desire to learn. Even with a motivation to learning, reading usually gives a one-way communication with no feedback or interaction. As for the contents conveyed through reading, the majority of reading materials provide only a one-dimensional information flow, which means a structured sequence from the first page to the last page. The sequence is usually what the authors believe to be the best for the readers. However, in our learning and teaching experiences, the structure of one book may not match every reader’s need. Furthermore, natural learning experiences are usually not one
