【摘要】 在混合式教学模式下，为了明确学生的学习效果所处的预警等级，选取线上学习通平台中可量化的学习指标作为研究对象，运用主成分分析法将这些具有相关性的指标简化为能够反映学生学习效果的综合性指标，并建立综合评价模型。学生可以利用该模型对自己的学习效果预警等级进行预测，根据不同的预警等级，学生可以及时地做出不同的调整策略。更多还原

【Abstract】 In order to make clear the early warning level of students’ learning effect under the blended teaching mode, the learning indicators in online learning platform were selected as the research object, and principal component analysis method was used to simplify these indicators into comprehensive indicators which could reflect the students’ learning effect, so as to establish a comprehensive evaluation model. Using this model, students could predict their own early warning level of learning effect, and according to different level, students could make different adjustment strategies in time.更多还原
