2023年8月第4期兴义民族师范学院学报JournalofMinzuNormalUniversityofXingyiAug2023No.4核心素养视阈下中小学“三度”数学课堂构建的再思考李龙梅1严虹2（1.贵阳市第四十一中学，2.贵州师范大学数学科学学院，贵州贵阳550007;贵州贵安新区550025)摘要：对于优质高效数学课堂构建的探索是当前“双减”背景下中小学数学教学提质增效的核心内容之一。在已有研究(“有温度”“有广度”“有深度”数学课堂构建)的基础之上，将“有效度”增加至“三度”数学课堂当中作为最终目标，进行中小学“四度”数学课堂的内涵界定与关系探讨，分别针对“四度”数学课堂实施途径进行深入探讨：“有温度”需要将“温度”融入到课程目标、问题情境、例题习题等等当中；“有广度”需要对课程内容有三个层次把握、对问题情境突出“真实性”“任务性”、对教学过程进行主题式探索等等；“有深度”需要巧妙设置数学情境、问题驱动、活动探索等等；“有效度”需要课前充分了解学生学情、课中灵活选择学习方式、课后有效整合数学作业。关键词：温度；广度；深度；效度；优质高效数学课堂中图分类号：G623.5‘Three-Degree'MathClassroomfromthePerspectiveofCoreLiteracy2.SchoolofMathematicalScience,GuizhouNormalUniversity,Gui'anNewAreaGuizhou550025)Abstract:Aimingatthe“doublereduction"goal,theexplorationofhigh-qualityandefficientmathclassroomsisacorecontentforthestudyofmathteaching.Basedontheexistedmathclassroom“Three-Degree”(warmth,breadth,depth)theory,“effectiveness"willbeaddedinasanultimategoalofmathclassrooms.Thisarticleexplorestheconnotationandrelationshipofthe"Four-Degree"mathematicsclassroominprimaryandsecondaryschools,anddelvesintotheimplementationmethodsofamathematicsclassroom.To"warmth",itrequiresintegrating"temperature"intocurriculumobjectives,problemsituations,exampleexercises,andsoon.To“Breadth",itisnecessarytograspthecoursecontentatthreelevels,highlighttheauthenticityandtaskfulnessofproblemsituations,andexploretheteachingprocessinathematicmanner.To“depth",mathematicalcontexts,problemdriving,activityexplorationsarerequired.To“effectiveness",athoroughunderstandingofstudents'learningsituationbeforeclass,flexibleselectionoflearningmethodsduringclass,andeffect...
