摘　　要：研究在混合教学模式下,进行3轮干预策略的设计以促成有效同伴反馈,利用相似度重复检测算法SNM和百度AI短文本相似度接口进行无效反馈筛除,参照Murphy的批判性思维框架对干预后同伴反馈文本进行编码,采用认知网络分析法对不同干预策略下批判性思维的发展特征进行分析.研究结果显示:经过群体干预、个体评分干预和个体评语干预,学习者群体的批判性思维逐渐从辨识与理解向分析与评价发展;分组分析中3轮干预仅个体评语干预有显著性差异,其中:不同绩点水平的学习者中,高分组在批判性思维各要素之间的连接更为紧密,更加关注分析与评价能力的结合;不同性别的学习者中,男性组侧重理解和评价能力,女性组则更侧重辨识与分析能力.同时,研究从学习分析视角探究3类干预策略下,同伴反馈如何促进高阶批判性思维的发展.This is an interventional study in blending learning,which involves three types of intervention measures designed to en-hance the efficiency of peer feedback.A detection algorithm of the duplicate record based on SNM(sorted neighborhood method)was utilized for data cleaning,and the Baidu AI’s interface for short text similarity was also employed to eliminate the invalid feedback text.Following Murphy’s critical thinking framework,the effectiveness of peer feedback after intervention was evaluated by encoding the feedback text and analyzing the developmental characteristics of critical thinking through ENA(epistemic network analysis).The results of the study indicate that:1)through team intervention,individual score intervention,and individual comment intervention,the critical thinking of learners gradually shifts from recognition and understanding to analysis and evaluation;2)only individual comment intervention showed significant differences among the three types of intervention.Among learners with different GPA(grade point aver-age)levels,the connection of critical thinking elements belonging to the high score group is closer than the low score group.The high score group pays more attention on the combination of analytical and evaluative abilities;3)among learners of different genders,the male group focuses on understanding and evaluation,while the female group focuses more on recognition and analysis.The study also explores peer feedback under three types of intervention measures from a learning analysis perspective,aiming to promote the develop-ment of higher-order critical thinking through feedback.
