| Under the background of new engineering,how to strengthen the cultivation of talent has always been a challenging issue.With the rapid development of mobile Internet,Internet of Things and the popularity of various mobile terminals,mobile application development is in the ascendant,and the demand for application development based on the Android system continues to grow.However,there is no corresponding Android development capability evaluation system.Therefore,how to better cultivate Android developers and build Android development capability evaluation system has theoretical significance and strong practical value.This thesis aims at Android development capability evaluation,combines cognitive diagnosis theory,sorts out knowledge points related to Android development,designs the cognitive diagnosis model PMFplus for the Android development capability modeling.On this basis,the online evaluation system of Android development capability based on personalized test questions is designed and implemented.The system is based on the developer's capability distribution and recommends questions for developers.The developer improves the knowledge system and the Android development capability through the pertinent practice of the test questions.Finally,the PMFplus and the related algorithms are compared in the public data set,and the three parameters,accuracy rate,recall rate and comprehensive price index,are used as the evaluation indicators of the algorithm.The experimental results show that the comprehensive price index of the PMFplus algorithm in this paper is increased by 64.15%,15.62%and 11.91%respectively compared with other algorithms.Further,by evaluating the examination records of the developers on the system,the analysis of the test records proves that the test questions recommended by developers are interpretable.Through the use of this system,we can cultivate qualified talents for enterprises and make certain contributions to the development of new engineering education. |
