    摘要: The study of fifth grade to "cross-denominator fraction addition and subtraction" unit for the scope of the study, according to the teaching objectives, sub-skills, the type of error, so as to Bayesian inference network as a tool to establish a set of Bayesian network to computer-based diagnostic tests national minority subjects, the diagnosis of students' error types, provide teaching reference. The results are as follows:
    First analysis of "cross-denominator fraction addition and subtraction, "the teaching materials, the establishment of the concept of proposition from proposition based on the concept of a computerized diagnostic test, sampling by using Bayesian network as a post-analysis tools, inference and sub-types of errors the students skills.
    The results are as follows:
    1. The self of the fifth grade of elementary school mathematics "different
    denominator fraction addition and subtraction,"unit test questions, the test of
    Cronbach's α value of 0.737, with questions of this study showed good reliability.
    2. Students of computer-based diagnostic expert identification of the type of error and
    the correct type of error rates were 95.3333%, 95.3333%, 93%, 89%, construction
    problems of diagnosis the average correct response rate of 93.1667%.
    3 Four models of sub-skills to identify the type of error rate and pattern of the overall
    average recognition rate were 90%, display mode helps to enhance the recognition
    rate.
