摘要
近年来,倡导个性化教学的呼声不断增大,作为个性化教学的先导,学习分析技术是广大教育研究者关注的焦点。采集学习者学习相关数据并进行处理分析,用于预测、评估和优化教与学,为实施个性化教学提供有效的技术支撑,是实施学习分析技术的核心。而从国内学习分析的研究现状以及国内外相关模型来看,学习分析模型应是一个包含数据收集、数据分析、评估预测与干预这三个阶段的循环结构。学习分析评估、预测与优化教学的应用策略为:以学习者数据与学习环境数据为基础,对学习者知识掌握程度进行评估;根据学习者历史学习数据,对其学习发展趋势进行预测分析;以评估预测结果为导向,及时实施教学干预、优化教学过程。它为大数据支持下的学习分析应用研究,提供一种参考思路。
With the proposition of personalized learning in recent y ea rs, learning analytics as the premise of personalized teaching has been the focus of the general education workers.Based on the domestic research status and the relevant models of learn-ing analytics, the model of learning analytics should be a loop structure which embraces data collecting, data analysis, evaluation, forecast and intervention. The learning analytics - application strategy, namely, evaluation, forecast and optimization of teaching and learning should be carried out as follows, Evaluating the users - degree of knowledge based on their learning history and environmen-tal data. And according to their learning data, forecasting their development trend of learning. Intervening the teaching and learning, optimizing teaching process in time guided by the results of evaluation and prediction. It may provide a different way of thinking to learning analytics application research based on educational big data.
