An Internet course in NDE/NDT technology and applications is being developed as part of the North Central Collaboration for NDE/NDT Education to complement new course materials and instructional modules for use in NDE/NDT technician programs, curriculum redevelopment, and innovation in NDE/NDT technological education in community and technical colleges. Java applets provide a widely used mechanism for platform-independent interactive graphics applicable to learning environments. Embedded in web pages, Java applets enhance the understanding of a physical phenomenon with adaptive visualization. Additionally, many applets can serve as an on-line calculators often required as part of NDE/NDT inspection planning. This paper demonstrates the application of Java applets to basic ultrasonics education via the internet.
