面向对象的学习分析模型的构建与实现

The Construction and Implementation of an Object-Oriented Learning Analytics Model

学习分析作为数字化学习绩效评价的主要手段，是目前教育技术领域研究的热点之一。为了使学习分析能够更有针对性地指导教学过程，该文从利益相关者的角度构建了面向对象的学习分析模型，其特征是基于面向对象方法学的理论创建学习对象类，具有对象的封装性和类的继承性。根据应用环境的约束和学习分析目标的方向性设计了一组方法，可对学习数据变量进行量化计算，实现在教学过程中有针对性地实施干预。以计算机操作系统课程教学为例，采用对照实验来验证该模型的可靠性与有效性。实验结果表明，面向对象的学习分析模型可以优化教学过程、为教与学提供参照与指导，并能有效地提升学生的学习效果，实现个性化学习。

Learning analytics is the primary means of digitizing performance evaluation of learning.It is a focus of current research in the field of educational technology. In order to make learning analytics being more targeted guide the teaching process，this paper builds an object-oriented model for learning analytics from the perspective of stakeholders. The features of model is based on the object-oriented methodological theory to create learning objects classes which have the encapsulation nature of objects and the inheritance nature of classes.We design a set of methods according to the constrains of applied environment and the directivity of learning analytics goals.It can be used to quantify and calculate the variable of learning data and then targeted implement interventions in teaching. This paper makes contrast experiments for the teaching of computer operating system course as example to prove the reliability and validity of this model.Experimental results show that the object-oriented model for learning analytics can optimize the teaching process，it provide references and guidance for teaching and learning.This model enhances the students learning effect effectively and realizes personalized learning.
