高中化学选修三与必修的衔接关系及其教学研究摘要在中学化学教学中，存在着许多教学问题，而教学知识的联系是一个重要的问题。首先，与必修课相比，选修课更难教。教材中必修化学教材新课程改革后，教学的概念主要是总结分析，不涉及实质性的问题，在选修课程中，很多课程都比较复杂，有些比知识化学竞赛的难度更大，知识水平跨度大，引导学生掌握知识，更困难的热情，使学生学习化学知识的下降。第二，教学中知识内容的重复。大部分必修课都是基础知识，选修课对基础知识有深刻的认识，但大部分仍讲解基本知识，知识重复严重。本文分析了高中化学选修3与必修的衔接关系，并在此基础上提出了必修模块和选修模块的教学衔接策略。关键词：高中化学选修三必修衔接教学ABSTRACTInhighschoolchemistryteaching,therearemanyteachingproblems,andtheconnectionofteachingknowledgeisanimportantproblem.First,comparedwiththerequiredcourses,theelectivecoursesaremoredifficulttoteach.Afterthenewcurriculumreformofchemistrytextbookincompulsorytextbooks,mostlythesummaryandanalysisoftheconceptofteaching,doesnotinvolvesubstantiveissues,inelectivecourses,manycoursesaremorecomplex,someevenmorethanthedifficultyofchemistrycontestofknowledge,knowledgelevelspanlargeleadstudentstograsptheknowledgemoredifficultenthusiasm,makestudentslearnchemistryknowledgedecline.Secondly,thereisalsoarepetitionofknowledgecontentinteaching.Mostofthecompulsorycoursesarebasicknowledge,andelectivecourseshavedeepknowledgeofbasicknowledge,butmostofthemstillexplainbasicknowledge,andknowledgerepetitionisserious.ThispaperanalyzestheconnectionbetweenthefourandthecompulsoryinHighSchoolElectiveElectivechemistry,andonthisbasisputsforwardtheteachingconnectionstrategyoftherequiredmoduleandtheelectivemodule.Keywords:highschoolchemistry;electivefour;compulsory;cohesion;teaching目录一、引言..................................................................1二、相关概念..............................................................1（一）化学必修模块........................................................................................................1（二）化学选修模块........................................................................................................1（三）教学衔接................................................................................................................2三、普通高中化学选修3与必修的衔接点......................................2（一）课程标准中选修3与必修的相关内容标准........................................................2（二）云南省关于必修教材与选修3中关联知识点的教学要求................................31.云南省关于必修1与选修3中关联知识点的教学要求....................................32.云南省关于必修2与选修3中关联知识点的教学要求....................................4（三）相关知识点在人教版教材中所处位置................................................................4四、必修模块和选修模块教学衔接策略........................................6（一）有效处理统一性和选择性之间的关系................................................................6（二）加强新旧知识之间的整合....................................................................................6（三）有效把握必修课和选修课的分层要求................................................................6五、结语..................................................................6参考文献..................................................................7一、引言高中学生学习化学的第一必修课，文理分科后...
