It seems that every time I turn around, my mailbox is filled with hardware, software, and technology information. Consider your computer as one more important tool. Give students basic skills to become efficient users of the computers by providing them with highly structured, relevant introductions with lots of teacher guidance, and then gradually release them to use those skills to accomplish the curricular goals. Practice skills lead naturally to more sophisticated programs in the upper grades. Let's keep in mind that in computer use, as in all things, a balance is healthy.
Computers are tools meant to make our work, school or otherwise, easier.
