"In response to Mr. Keplinger's commentary on Computer Assisted Instruction – Worth The Effort?, I say a big positive yes. Going on four years without a promotion in the Air Force, I purchased the Atari 400 computer. I programmed all of my study material multiple choice questions and answers that I could find and had the computer drill me day after day. When it came to test for promotion, it seemed that I knew all the answers. A month later, I was notified of my promotion. Computer assisted instruction really works." Bob Holsti
