We were looking for a management tool to enhance instruction and to allow the monitoring of students as they work. We tried several network systems but found the intensive graphic requirements of the cad and 3D solid modeling software made the video response too slow.I saw the LINK System used at a local college, that was all it took. I knew I had to have it! The ability to focus each student on their own screen during direct instruction is invaluable. The ability to take control of the student station from the teacher station is important. If a student has a question there is no need to go to that station. If you would like to use that student’s screen for helping or instructing other students you can transmit that individual student’s screen to all the other student stations. We have used the LINK System since 1999. Applied Computer Systems is excellent. Their customer service is second to none! They are prompt, and courteous. If you call with a problem, they will do whatever it takes to solve that problem.
