摘要

目的:本研究旨在提出一种全新的利用学习模糊认知图(LFCM)方法预测学生成绩的方法。背景:学生学习成绩预测一直是许多学科的重要研究课题。不同的数学模型被用来预测学生的表现。虽然现有的常用预测方法,如人工神经网络(ANN)和回归,可以很好地处理大数据集,但它们在处理小样本量方面面临挑战,限制了它们在实际实践中的实际应用。方法:本文采用六种不同类别的绩效前因,分别是课程特征、LMS特征、学生特征、学生参与、学生支持和制度因素,以及每个类别中的测量项目。此外,我们采用学生满意度、知识建构水平和学生GPA三项指标来评估学生的整体表现。我们收集了30名研究生在随后四个学期的纵向数据,并使用学习模糊认知图(LFCM)技术对数据进行了分析。贡献:本研究提出一种全新的方法,学习模糊认知图(LFCM)来预测学生的表现。使用这种方法,我们确定了学生表现的最具影响力的决定因素,如学生参与度。此外,本研究描绘了学生表现决定因素之间的相互关系模型。结果表明,在样本量有限的情况下,该模型能较好地预测进入序列。结果还显示,学生在LMS中的总在线时间和学习间隔的规律性对整体成绩的影响最大。学生参与类别对学生的整体表现也有最高的直接影响。对从业者的建议:学术机构可以使用本文中开发的结果和方法来识别学生的表现前因,预测表现,并制定行动计划以解决长期的缺点。教师可以根据短期内学生的反馈在操作层面上调整自己的学习方法。对研究人员的建议:研究人员可以使用本研究提出的方法来处理其他领域的问题,例如将LMS用于组织/机构教育。此外,他们可以关注所提出模型的具体维度,例如探索如何提高学生在学习过程中的参与度。对社会的影响:我们的研究结果显示,学生是学习过程的中心。他们对学习的投入程度是决定学习效果的最关键因素。因此,学习者应该考虑到这一发现,以便从学习过程中获得价值。未来研究:作为未来工作的潜力,建议的方法可以在其他情况下使用,以测试其适用性。未来的研究还可以通过调整模型的元素来提高所提出的LFMC模型的性能水平。

A Learning Fuzzy Cognitive Map (LFCM) Approach to Predict Student Performance
Aim/Purpose: This research aims to present a brand-new approach for student performance prediction using the Learning Fuzzy Cognitive Map (LFCM) approach. Background: Predicting student academic performance has long been an important research topic in many academic disciplines. Different mathematical models have been employed to predict student performance. Although the available sets of common prediction approaches, such as Artificial Neural Networks (ANN) and regression, work well with large datasets, they face challenges dealing with small sample sizes, limiting their practical applications in real practices. Methodology: Six distinct categories of performance antecedents are adopted here as course characteristics, LMS characteristics, student characteristics, student engagement, student support, and institutional factors, along with measurement items within each category. Furthermore, we assessed the student’s overall performance using three items of student satisfaction score, knowledge construction level, and student GPA. We have collected longitudinal data from 30 postgraduates in four subsequent semesters and analyzed data using the Learning Fuzzy Cognitive Map (LFCM) technique. Contribution: This research proposes a brand new approach, Learning Fuzzy Cognitive Map (LFCM), to predict student performance. Using this approach, we identified the most influential determinants of student performance, such as student engagement. Besides, this research depicts a model of interrelations among the student performance determinants. Findings: The results suggest that the model reasonably predicts the incoming sequence when there is a limited sample size. The results also reveal that students’ total online time and the regularity of learning interval in LMS have the largest effect on overall performance. The student engagement category also has the highest direct effect on student’s overall performance. Recommendations for Practitioners: Academic institutions can use the results and approach developed in this paper to identify students’ performance antecedents, predict the performance, and establish action plans to resolve the shortcomings in the long term. Instructors can adjust their learning methods based on the feedback from students in the short run on the operational level. Recommendation for Researchers: Researchers can use the proposed approach in this research to deal with the problems in other domains, such as using LMS for organizational/institutional education. Besides, they can focus on specific dimensions of the proposed model, such as exploring ways to boost student engagement in the learning process. Impact on Society: Our results revealed that students are at the center of the learning process. The degree to which they are dedicated to learning is the most crucial determinant of the learning outcome. Therefore, learners should consider this finding in order the gain value from the learning process. Future Research: As a potential for future works, the proposed approach could be used in other contexts to test its applicability. Future studies could also improve the performance level of the proposed LFMC model by tuning the model’s elements.
