新课标下初中数学有效性课堂教学策略研究

新课标下初中数学有效性课堂教学策略研究摘要随着新课程标准的改革，初中数学传统教学方式已经逐步被替代，取而代之的是新课标下所倡导的启发式、探究式、参与式、互动式等多样化的教学方式。如今，人们对初中数学课堂教学有效性的关注日益增强。本文通过文献研究、案例分析与实践经历相结合的方法开展研究，从教师和学生两个角度出发，深入分析了新课标下初中数学有效性课堂教学的现状。主要有教师教学观念落后、教学经验有限：学生学习态度消极、自我认知感不足。提出影响新课标下初中数学课堂有效性的问题：部分教师仍采用传统的灌输式教学、运用题海战术、滥用新课标下所倡导的教学方式：学生课堂上主动参与度低、学习兴趣不高、学习方法不当。针对问题提出新课标下初中数学课堂教学的策略，包括在导入环节的改进策略、跨学科教学的策略、有效提问的改进策略、合理利用多媒体辅助教学的策略以及有效进行小组合作的策略。并将上述策略在六个案例中进行了应用及分析。最后，文章总结了研究的观点和不足，并对未来的研究方向进行了展望，希望能够促进初中数学教学的发展，为初中数学教师提供更多的教学策略选择。关键词：新课标：初中数学：有效性：课堂教学策略AbstractWith the reform of the new curriculum standards,the traditional teaching methods of juniorhigh school mathematics have been gradually replaced,replaced by heuristic,inquiry-based,participatory,interactive and other diversified teaching methods advocated under the newcurriculum standards.Nowadays,people have paid more and more attention to the effectivenessof junior high school mathematics classroom teaching.Through the combination of literatureresearch,case analysis and practical experience,this paper analyzes the current situation ofeffective classroom teaching of junior high school mathematics under the new curriculumstandard from the perspectives of teachers and students.Students have a negative attitudetowards learning and a lack of self-awareness.The problems that affect the effectiveness ofjunior high school mathematics classrooms under the new curriculum standard were raised:someteachers still used traditional indoctrination teaching,used the tactics of sea of questions,andabused the teaching methods advocated under the new curriculum standard.Students'activeparticipation in the classroom is low,their interest in learning is not high,and their learningmethods are inappropriate.In view of the problems,the strategies for teaching junior high schoolmathematics in the classroom under the new curriculum standard are proposed,including theimprovement strategies in the introduction process,interdisciplinary teaching,effectivequestioning,rational use of multimedia to assist teaching,and effective group cooperation.Theabove strategies were applied and analyzed in six cases.Finally,this paper summarizes the viewsand shortcomings of the research,and looks forward to the future research directions,hoping topromote the development of junior high school mathematics teaching and provide more teachingstrategy options for junior high school mathematics teachers.Keywords:new curriculum standard;Junior high school mathematics;Validity;Classroomteaching strategiesⅡ目录第1章引言1.1研究背景1.2研究意义第2章新课标下初中数学有效性课堂教学的理论基础」22.1相关概念界定.22.1.1新课标22.1.2有效教学….22.2建构主义学习理论…2第3章新课标下初中数学课堂教学现状及存在的问题…33.1新课标下初中数学课堂教学现状…33.1.1教师方面33.1.2学生方面。33.2新课标下初中数学课堂教学存在的问题分析43.2.1教师方面.43.2.2学生方面.….4第4章新课标下初中数学课堂教学有效性策略及应用….64.1导入环节改进...64.1.1联系生活情景进行教学一一以《食材比例问题》为例64.1.2重视类比导入法一一以《异分母分式加减法》为例74.2跨学科教学在《平面向量的加法》中的应用.84.3有效提问的改进一一以《多项式与多项式相乘》为例.104.4合理利用多媒体辅助教学一一以《角平分线的性质》为例.114.5有效进行小组合作一一以《全等三角形判定定理的应用》为例13结论参考文献….17致明..8第1章引言1.1研究背景随着国家在各方面发展水平的提高，国家对人才的需要亦是希望能够是高水平的，因此国家在培养人才的教育上变得更加注重，对数学能力的要求也愈发变高。
