Teachers in the Knoxville school district are taking some lessons of their own this summer. They received training Thursday on how to use their brand new MacBook Pros. Knoxville students in grades 7-12 will have their own MacBook Pros provided by the school district sometime during the first semester next school year. Teachers say that this will allow easier communication with their students and allow such simple things as document sharing, so if a student loses a worksheet, they can go online and print off a replacement.
