Abstract : A summary is presented of two research projects in the area of computer-aided instruction and man-computer interaction. In 1965 Rosenberg completed a study entitled Computer Aided Teaching of Dynamic System Behavior (AD-640 681). This study demonstrated that within the delimited area of formal engineering theory a computer simulated laboratory could be built in which freshman students could pose problems, observe displays of machine responses, and thereby learn formal discipline with only minor interaction with a human teacher. An outline of Rosenberg's experiment and conclusions is given in this report, along with some more general 'Observations on the Use of Computers in Instruction,' dealing with prospects for computerized tracking monitors. In June 1966 McCandlish completed a study entitled A Computer Simulation Experiment of Supervisory Control of Remote Manipulation, (to be published). McCandlish summarizes how, for a formally well-defined task like grasping a block with a pair of jaws, removing the block from a hole and placing it in a second hole, the human can perform the task through the computer, but only with certain difficulties. He investigated such display rate, time delay between human responses and knowledge of results, and nature of command statements. An outline of McCandlish's experiment and conclusions is given in this report followed by 'Observations on the Relation Between Computer-Aided-Instruction and Computer-Aided-Control,' the latter being where the human serves as a supervisor and subgoal setter of a lower level semi-automatic system which interacts directly with the environment to accomplish a task.
