![]() The system has been tested by Physics students in more than 80 problemsolving sessions and the results have been good. ALBERT permits a mixed initiative dialogue in the discussion of a problem. The context model consists of a student model, a tutorial status model and a dynamic dialogue model. The tutorial is driven by a tutorial management system (embodying a tutorial model) and a context model. The result has been a fairly robust language interface. First an attempt is made to understand the input with the pattern recognition system, and if that fails, a keyword matching system is invoked. ![]() The tutorial dialogue system uses a modified version of the natural language interface which operates in a two-tier fashion. The natural language interface and both the problem-solvers are fast and completely adequate for the task. It employs a forward-directed problem-solving strategy. ![]() The other uses the definition of acceleration and the relationship between displacement and average velocity to solve the problems. One is goal-directed and solves the problems using the standard kinematic equations. Two problem-solving routines are included in ALBERT. The natural language system has understood over 60 problems taken directly from elementary Physics textbooks. The interface is based on a pattern recognition system which is intended to parallel a cognitive model of language processing. A natural language interface was designed to understand kinematics problems stated in textbook English. The program is implemented in the TUTOR language and runs on the Control Data mainframe PLATO system. ALBERT understands the problems, knows how to solve them, and can teach students how to solve them. Students may type in kinematics problems directly from their textbooks. These two experiments will be used in the Modern Physics Laboratory course, PHYCS 262.ĪLBERT, an intelligent problem-solving monitor and coach, has been developed to assist students solving problems in one-dimensional kinematics. ![]() The acquired data is presented graphically and saved on floppy disk for further analysis. Both the transient and stead-state behavior of the temperature distribution is studied. A known heat source is attached to one end of the rod and the other end is maintained at room temperature. Eight thermocouples, located along the length of the rod, monitor temperature as a function of time. The computer system displays the information in graphical format and saves the data on floppy disks for further analysis.The second experiment studies the heat flow along a cylindrical copper rod. Two demonstration experiment have been designed to explain how the system functions and how it may be utilized in a laboratory setting.An experiment in optical spectroscopy will allow students to automatically scan the spectra of a light source and collect data concerning wavelength and line intensity. This thesis describes an automated data acquisition system based on a personal computer that has been modified for use as a scientific instrument in an undergraduate physics laboratory. ![]()
