摘要随着我国经济的发展，我国越来越重视学前教育。而相关规定指明幼儿园中游戏应作为儿童基本活动。其中，区域活动的益智区是智力游戏的开展落实的集中表现，也是幼儿生理和心理发展的重要区域。幼儿可通过操作游戏材料，促进智力发育，因此材料的投放至关重要。本研究采用文献法，观察法以及案例分析法在西安市某幼儿园内分别选取一个大班，共计3个班级，对其益智区游戏材料投放的问题及现状进行研究与分析，通过研究发现，幼儿教师在对益智区材料投放的“四性”体现不够明确；材料投放与集体教学活动关联性较弱；材料的操作规则不够明确；本研究针对幼儿益智区现状在材料投放方面也给出了解决建议：投放材料应关注幼儿的具体实情，同时应遵循“四性”原则即动态性、层次性、开放性和多样性，让幼儿清晰知道使用材料的规则；游戏材料应关联主题活动，挖掘其多种教育价值等；在教师指导方面要充分尊重幼儿的主体性，给予幼儿游戏自由；正确认识教师多种角色和儿童差异性，灵活运用指导策略。关键词：大班，益智区材料，投放策略AbstractChina'seconomycontinuestodevelop,andChinaispayingmoreandmoreattentiontopreschooleducation.Therelevantregulationsindicatethatgamesinkindergartensshouldbeusedasbasicactivitiesforchildren.Amongthem,theregionalactivitypuzzleareaisaconcentratedexpressionoftheimplementationofintellectualgames,andisalsoanimportantareaforthephysiologicalandpsychologicaldevelopmentofyoungchildren.Youngchildrengetfeedbackbydirectlyoperatingthegamematerial,sothematerialhasagreatguidingeffectonyoungchildren.Thispapermainlyusedtheliteraturemethod,observationmethodandcaseanalysismethodtoselectalargeclassinakindergarteninXi'an,atotalof3classes,tostudyandanalyzetheproblemsandcurrentsituationofthegamematerialsinthepuzzlearea.Preschoolteachersarenotclearaboutthe“fourcharacteristics”ofthematerialsinthepuzzlearea;thematerialplacementisweaklyrelatedtothecollectiveteachingactivities;theoperationrulesofthematerialsarenotclearenough;thisstudyalsoproposesthematerializationofthechildren'spuzzleareaintermsofmaterialplacement.Correspondingsuggestion:Materialdeliveryshouldfollowthe"four-sex"principleofopenness,hierarchy,diversityanddynamics,andconsidertheactualsituationofyoungchildren,sothatchildrencanclearlydefinetherulesofmaterialoperation;gamematerialsshouldberelatedtothematicactivities,andexploretheirvariouseducation.Value,etc.;Intheguidanceofteachers,itisnecessarytofullyrespectthesubjectivityofyoungchildrenandgivechildrenthefreedomofplay;correctlyunderstandthemultiplerolesofteachersandchildren'sdifferences,andflexiblyusetheguidingstrategy.Keywords:Bigclass,Puzzleare
