Research on Cutting Knowledge Points in Intelligent Computer Aided Instruction
JI Cheng-chao · Computer Technology and Development · 2009
Emergence of intelligent computer aided instruction(ICAI) makes CAI being applied widely.ICAI can help learner consolidate related knowledge points.According to IEEE 1484,a special ICAI is designed.When cutting knowledge points from courseware,learning materials and examinations question database,it is very easy to produce ambiguity.Therefore,an algorithm for ambiguous word eliminating is presented and analyzed.Simulation examination proves that the algorithm based on ICAI increases the recall rate and precise rate by 1% and 3% respectively.At last,sectional functions of ICAI is introduced.Practice test illustrates that cutted knowledge points didn't appear ambiguous after ambiguous word eliminating in one chapter.
