Many students come to Middle School thinking technology is "stuff that deals with computers" or have no idea what so ever. Technology, as a subject, is a way of answering today's challenges.
Parents you may remember "shop" classes where you used a variety of different tools to make something. Today's educational goals replaced that shop class with Technology. Your child will be learning how to design, build and apply solutions to problems with various tools, materials and the knowledge learned in their core subject areas.
In a simple view, your child will learn what an engineer, designer or technician may face in their job on a daily basis.
