The Internet offers trade and industrial (T&I) educators a wealth of readily available information for use as teaching aids, supplemental materials, and laboratory resources. These materials provide many distinct benefits; however, there are also several issues that must be addressed when using the Internet as an adjunct in teaching. These benefits and issues must be weighed when deciding whether to use Internet resources in T&I classrooms and laboratories. Above all, using the Internet in T&I programs helps students develop computer and related technical skills. T&I students may use the Internet in many ways; for example, students can conduct research on historical aspects of their discipline, find vendor sites, or explore employment opportunities. The Internet can also be used for integration activities with academic disciplines. Students will need access to some type of Internet service provider. Security-related issues include ensuring that students do not gain access to individual student, school, or district information and ensuring that students do not access sites containing inappropriate materials. T&I teachers must address these same security issues when deciding whether to use course software to place portions of a class on the Internet. T&I teachers must also realize that using course software creates a time constraint. (MN)
