The design of pedagogical agent for distance virtual experiment

Experimental learning about electric-machinery is high risk and time-consuming, students do not always enjoy the laboratory, the teacher also needs to pay full attention to all students and equipment, besides it is hard to provide enough machine sets and space for learning. So it is our motivation to design a virtual laboratory for the teaching of electric-machinery experiment by Internet under the more real environment without concern about danger or limitations. It is taught by an experienced teacher using a pedagogical agent which is the most important key factor. Taking the above features into consideration, an interactive virtual laboratory based on an expert system has been designed and implemented to improve the learning, operation and control in electric-machinery experiments. The system set up is a highly intelligent and interactive mechanism. Through the system, students could have a more complete environment for distance learning
