随着教育信息化的普及与逐渐深入,学习管理系统已经获取并存储了大量的有关学生复杂学习行为的数据,从这些数据中挖掘出改进教学系统、提升学习效果的信息,在教育信息化领域一直有着巨大的吸引力。因此,有必要从分析数据以改进学习的角度,对日益受到关注的学习分析技术进行解读。首先,学习分析技术是测量、收集、分析和报告有关学生的学习行为以及学习环境的数据,用以理解和优化学习及其产生的环境的技术。接着,综述学习分析技术的发展,指出其在教育中有着广泛的应用前景和巨大的发展潜力：学习分析技术可作为教师教学决策、优化教学的有效支持工具,也可为学生的自我导向学习、学习危机预警和自我评估提供有效数据支持,还可为教育研究者的个性化学习设计和增进研究效益提供数据参考。最后,提出学习分析技术也存在隐私、准确性和兼容性等诸多挑战和问题。
隨著教育信息化的普及與逐漸深入,學習管理繫統已經穫取併存儲瞭大量的有關學生複雜學習行為的數據,從這些數據中挖掘齣改進教學繫統、提升學習效果的信息,在教育信息化領域一直有著巨大的吸引力。因此,有必要從分析數據以改進學習的角度,對日益受到關註的學習分析技術進行解讀。首先,學習分析技術是測量、收集、分析和報告有關學生的學習行為以及學習環境的數據,用以理解和優化學習及其產生的環境的技術。接著,綜述學習分析技術的髮展,指齣其在教育中有著廣汎的應用前景和巨大的髮展潛力：學習分析技術可作為教師教學決策、優化教學的有效支持工具,也可為學生的自我導嚮學習、學習危機預警和自我評估提供有效數據支持,還可為教育研究者的箇性化學習設計和增進研究效益提供數據參攷。最後,提齣學習分析技術也存在隱私、準確性和兼容性等諸多挑戰和問題。
