Design and Implementation of Blank-Filling Test Module in the Theory Examination System for Tower Cranes

In order to achieve the function for automatic test paper and automatic scoring of blank-filling test module in the theory examination system for tower cranes, first of all, the blank-filling is classified based on the answer complexity of blank-filling, and the questions of blank-filling related table structure are designed. Then, test paper is automatically generated by extracting the corresponding questions based on the different random numbers generated random function rand (). Scoring is automatically accomplished by using the matching mode technology which compares the examinee answer and standard answer. Finally, the score is cumulated to calculated achievement for blank-filling test module by extracting the examinee score of the relevant information table. Therefore, the implementation of automatic test paper and automatic scoring can ensure the effectiveness of the test papers and the accuracy of the papers marked.
