Abstract: Due to the existence of several cognitive factors which are difficult to quantify in the cognitive ability evaluation, this paper presents the gray partial correlation evaluation to build cognitive student model. Firstly, the relationship of mutual influences in factors is discussed to get weight values by calculating partial correlation coefficient. Secondly, the comprehensive evaluation model is built based on the definition of the gray class and the whitenization weight function used for getting gray evaluation weights. Finally the model is verified with real case, which shows that the model is beneficial to evaluate the level of students’ knowledge and provides guidance for learning, simultaneously gives a reliable conclusion.

Key words: agile learning, cognitive ability, cognitive student model, gray partial correlation evaluation method
