An evaluation was made of computer assisted instruction on human relations skills implemented on the PLATO IV computer system. These materials had been devised for use by company commanders (CCs) at Naval Recruit Training Commands (RTCs). A substantial improvement on the part of CCs, and recruits of CCs undergoing this instruction, was found. Also, case study scenario-based materials were implemented on PLATO IV for complementary training in interpersonal skills. (Author)
