论文摘要
这项研究旨在为学生的学术绩效和研究策略预测开发机器学习模型,该模型可以推广到高等教育中的所有课程。对学生学习过程至关重要的关键学习属性(内在,外在,外在,自主性,相关性,能力和自尊)用于构建模型。确定这些属性对学生的学习成绩和学习策略的广泛影响是我们感兴趣的中心。为了调查这一点,我们使用Python中的Scikit-Learn来构建五个机器学习模型(决策树,K-Neart邻居,随机森林,线性/逻辑回归和支持向量机),以进行回归和分类任务,以执行我们的分析。使用智利作者通过定量研究设计收集的924名大学牙科学生的数据对模型进行了培训,评估和测试,以实现准确性。对模型的比较分析表明,基于树的模型,例如随机森林(预测准确性为94.9%),而决策树与线性,支持矢量和K-Nearest邻居相比显示出最佳的结果。这项研究中建立的模型可以用于预测学生的绩效和研究策略,以便可以实施适当的干预措施以改善学生的学习进度。因此,将可以改善学生学习属性的策略纳入在线教育系统的设计中可能会增加学生根据需要继续学习任务的可能性。此外,结果表明,可以将属性建模并用于调整/个性化学习过程。
This research aims to develop machine learning models for students academic performance and study strategies prediction which could be generalized to all courses in higher education. Key learning attributes (intrinsic, extrinsic, autonomy, relatedness, competence, and self-esteem) essential for students learning process were used in building the models. Determining the broad effect of these attributes on students' academic performance and study strategy is the center of our interest. To investigate this, we used Scikit-learn in python to build five machine learning models (Decision Tree, K-Nearest Neighbour, Random Forest, Linear/Logistic Regression, and Support Vector Machine) for both regression and classification tasks to perform our analysis. The models were trained, evaluated, and tested for accuracy using 924 university dentistry students' data collected by Chilean authors through quantitative research design. A comparative analysis of the models revealed that the tree-based models such as the random forest (with prediction accuracy of 94.9%) and decision tree show the best results compared to the linear, support vector, and k-nearest neighbours. The models built in this research can be used in predicting student performance and study strategy so that appropriate interventions could be implemented to improve student learning progress. Thus, incorporating strategies that could improve diverse student learning attributes in the design of online educational systems may increase the likelihood of students continuing with their learning tasks as required. Moreover, the results show that the attributes could be modelled together and used to adapt/personalize the learning process.
