THE USE OF A COMPUTER PROGRAM BY ENGINEERING STUDENTS TO SIMULATE A JOB SHOP THAT MANUFACTURES ELECTRONIC DEVICES HAS INDICATED THAT SIMULATION METHODS OFFER REALISTIC ASSISTANCE IN TEACHING. EACH STUDENT IN THE STUDY SUBMITTED SPECIFICATIONS FOR A CIRCUIT DESIGN AND, FROM THE COMPUTER, RECEIVED PERFORMANCE ASSESSMENTS OF THE CIRCUIT WHICH RESEMBLED THE INFORMATION AVAILABLE FROM THE ACTUAL BUILDING OF A DEVICE. SIMPLE PROCEDURES REQUIRING NO COMPUTER PROGRAM BACKGROUND WERE DEVELOPED FOR THE "HOMEWOOD JOBSHOP" PROGRAM. IN 9 WEEKS, STUDENTS WHO KNEW VERY LITTLE CIRCUITRY WERE ABLE TO SOLVE SUCCESSFULLY PROBLEMS OF SUFFICIENT COMPLEXITY TO CHALLENGE EXPERIENCED DESIGNERS. PSYCHOLOGICAL STUDIES RELATED TO LEARNING WERE CONDUCTED WHILE THIS RESEARCH WAS IN PROGRESS. (JM)
