To improve the instructional process, time shared computer-assisted instructional methods were developed to teach upper division undergraduate chemical engineering students the concepts of process simulation and analysis. The interactive computer simulation aimed at enabling the student to learn the difficult concepts of process dynamics by allowing him to assess and explore the dynamic behavior of simulated processes, assisted by the provision to him of immediate responses to the user-initiated changes of model parameters or inputs. A CDC-6600/6400 computer was used, along with FORTRAN and the DYFLO dynamic simulation routine, A simulation subrouting was prepared for pieces of process equipment, and homework modules containing information and procedures to be learned were assigned. Objectives of the modules were the transmission of facts and the development of operating experience including concepts such as start-up, shut-down, control, and process parameter sensitivity. Students were favorably oriented toward the material taught and to the computer as an instructional adjunct, and they absorbed factual matter well. However, successful operating experience was not achieved to the desired degree. (Author/PB)
