Indefinite Integral Automatic Analysis Mechanism Study — Using Basic Indefinite Integrals Involving Quadratic Square Roots as an Example

Abstract

Abstract-These researchers prepared a university calculus problem is structural model of knowledge "on the square root of the product of the second relates to the indefinite integral trigonometric substitution" effective testing program. After calculus courses and tests, in this study, Bayesian network analysis was used to find the best combination of recognition rate of Bayesian network, and easily identified these error types so that students might learn "trigonometric substitution" unit. Then, using the Bayesian probability analysis, the establishment of a "trigonometric substitution" unit modeled adaptive Bayesian network diagnostic test systems for example, the establishment of such structure and how it was used as a basis for developing remedial teaching statistical information to analyze.Index Terms-Indefinite integral, constructed-response item, error type, Bayesian network.
