These research projects, designed to delve into certain relationships between humans and computers, are focused on computer-assisted instruction and on man-computer interaction. One study demonstrates that within the limits of formal engineering theory, a computer simulated laboratory (Dynamic Systems Laboratory) can be built in which freshmen students can pose problems and observe displays of machine responses, thereby learning formal discipline. A second study deals with so-called student programed systems. This type of instruction provides a problem-oriented language which permits a student to construct a variety of responses within the confines of the language which in turn provide him with specific information. In the third study, the goal is the modeling of processes by which a human commands, through the computer, a real-time information system containing automatic subroutines which may be used to accomplish a task. The task consists of grasping a block with a pair of jaws, removing it from a hole, and placing it in a second hole. The final study discusses the relation between computer-aided control and computer-assisted instruction. In the former the man serves as a supervisor and subgoal setter for the computer, and in the latter the roles are reversed, with the machine setting the subgoals so that they can be achieved by the learner.
