    摘要: The research is based on the unit “arithmetical operations of Integers” of the first grade in junior high school to develop digital teaching materials and computerized adaptive diagnostic test (CADT) grounded in Bayesian Network and knowledge structure theories for the evaluation of the teaching effects. The teaching content with the present course divides into two units -“Addition and Subtraction of Integers”, “Multiplication and Division and mathematical operations of Integers” to carry out the appraisal of teaching result.

    The research uses quasi-experimental design to divide the subjects into experimental group and control group. The experimental group teachers use digital teaching materials to proceed to the course. After the experimental group students take the first CADT, carries out the remedial teaching of integrating into information technology. Then have the experimental group students take the second and the third CADT.

    The results of the three tests are viewed as the evaluation of using information technology in teaching and learning. The results are as follows：

    1. After taking experimental instruction, the number of items in two units administered by CADT is 24.20 and 18.11. There are 9.80 and 11.89 items to be economized. In addition, the prediction accuracy can reach 91.52％ and 91.67％.

    2. After taking remedial instruction, the number of items in two units administered by CADT is 23.45 and 17.10. There are 10.55 and 12.90 items to be economized. In addition, the prediction accuracy can reach 95.02％ and 94.62％.

    3. After taking learning retention instruction, the number of items in two units administered by CADT is 22.44 and 16.83. There are 11.56 and 13.17 items to be economized. In addition, the prediction accuracy can reach 95.31％ and 94.04％.



    4. For teaching and learning model, the study confirms that the learning performance of experimental group students is better than control group students in the effects of remedial teaching and retaining the post. The research has significant differences.

    5. For ability grouped performance, the study shows that the experimental group students of remedial teaching of addition and subtraction of integer effects in average scores are better than the control group students of traditional teaching. The research has significant differences.

    Keywords: addition and subtraction of integers, multiplication and division of integers, arithmetical operations of integers, Bayesian Network, Computerized Adaptive Diagnostic Test(CADT), information technology into teaching, learning retention
