PSO-Based Fuzzy Markup Language for Student Learning Performance Evaluation and Educational Application

Abstract

Fuzzy relationships exist between students' learning performance with various abilities and a test item. However, the challenges in implementing adaptive assessment agents are obtaining sufficient items, efficient and accurate computerized estimation, and a substantial feedback agent. Additionally, the agent must immediately estimate students' ability item by item, which places a considerable burden on the server, especially for a group test. Hence, the implementation of adaptive assessment agent is more difficult in practice. This paper proposes an agent with particle swarm optimization (PSO) based on a Fuzzy Markup Language (FML) for students' learning performance evaluation and educational applications, and the proposed agent is according to the response data from a conventional test and an item response theory (IRT)-based three-parameter logistic (3PL) model. First, we apply a Gauss-Seidel (GS)-based parameter estimation mechanism to estimate the items' parameters according to the response data, and then to compare its results with those of an IRTbased Bayesian parameter estimation mechanism. In addition, we propose a static-IRT test assembly mechanism to assemble a form for the conventional test. The presented FML-based dynamic assessment mechanism infers the probability of making a correct response to the item for a student with various abilities. Moreover, this paper also proposes a novel PSO-based FML (PFML) learning mechanism for optimizing the parameters between items and students. Finally, we adopt a K-fold cross validation mechanism to evaluate the performance of the proposed agent. Experimental results show that the novel PFML learning mechanism for the parameter estimation and learning optimization performs favorably. We believe the proposed PFML will be a reference for education research and pedagogy and an important co-learning mechanism for future human-machine educational applications.

Research on the Performance Evaluation of Ideological and Political Education of College Students Based on Fuzzy Comprehensive Evaluation

“…Students" issued by the State Council in 2004, it is pointed out that improving the ideological and political education of college students is of great strategic significance, and the ideological and political education of college students should be included in the educational evaluation system of colleges and universities. This fully shows that the state attaches great importance to the ideological and political education of college students (Lee, et al, 2018). The smooth development of ideological and political education in colleges and universities requires the establishment of a relatively perfect performance evaluation system of ideological and political education, which is of great significance for strengthening the construction of the basic theory of ideological and political education in colleges and universities and promoting the improvement of the quality of ideological and political education in China.…”

Study Of Students’ Performance Prediction Models Using Machine Learning

“…Overall, the neural network model has achieved a good prediction accuracy of 84.8%, along with limitations. [10] proposed an For students' learning performance evaluation and educational applications, a particle swarm optimization (PSO) agent based on the Fuzzy Markup Language (FML) is proposed, and the proposed agent is based on data analysis from a traditional test and an item response theory (IRT)-based three-parameter logistic (3PL) model. Finally, the proposed work employs a K-fold cross validation process to assess the efficiency of the proposed agent.…”
