It's important for your students to have a working knowledge of various computer applications such as Word, Excel, Access, Power Point, and so on for both college and the work place. A good course to consider is New Perspectives. If your children want to explore further computer skills such as web design, you may want to consider a self-teaching, hands-on tutorial approach . All these books may be available used on www.amazon.com so check there as well. The files you need to use with the courses can be downloaded from http://www.courses.com.
