| Abstract: | A predictive method of item difficulty was constructed via teacher's subjective evaluation,regression analysis and neural network modeling respectively.The optimum method stands out after comparison of the three kinds of predictive methods.The conclusions indicated that the three methods all have accuracy to prediction of item difficulty.According to the indications of relative errors,absolute errors and average errors,the BP neural network showed a better result of the prediction of item difficulty. |
