A STUCY OF SOLVING PHYSICS PROBLEMS THROUGH THE PRODUCTIVE RULE

用问题解决产生式系统编制样例题和试干题，可使学生掌握样例题中所蕴含着的产生式规则，表明能在较短时间内掌握教学计划中所规定的知识内容，图式获得较快，而规则自动化有较高要求。

The experimental results from 76 students indicated: 1) learning from examples and learning by doing were two important forms of learning. The learner could grasp the rule of solving problems; 2) The human cognitive ports of the productive system contained the schema acquistinn and the rule automation,whiCh would affect people in acquiring the rules of the preductiye syStem; 3) The examples could yield good rusults once the human subuect had grasps the productive system's rules and skills.
