【摘要】 项目式学习作为新课标所倡导的一种重要学习活动方式,其目的在于引导学生在真实情境中发现和提出问题,综合运用学科知识与方法解决问题,然而当前在实践层面却缺少指导性强的理论与可借鉴的应用案例。从项目式学习与问题解决的关联切入,以问题提出作为驱动力贯穿项目全流程。基于“小学数学问题提出框架(F-PosE)”,构建“目标定位—问题驱动—成果导向”实践模式,明确其在项目各环节的作用:助力确定核心问题、形成问题链、兼顾成果评价与激发拓展问题。结合示范案例,阐释框架应用,为教师提供可操作路径,以凸显学生主体性、发展数学思维与核心素养。更多还原

【Abstract】 Project-based learning,as an important learning activity advocated by the new curriculum standards,aims to guide students to discover and pose problems in real context and solve problems by applying disciplinary knowledge and method,but there is a lack of instructive theories and application cases in practice.Based on the relationship between project-based learning and problem-solving,this article takes problem posing as the driving force throughout the entire process of the project.Based on the framework for posing elementary mathematics problems,a practice model of goal-orientation,problemdriven and outcome-orientation is constructed,and its role in each link is clarified.It helps to determine core problems,form problem chain,evaluate outcome and stimulate extended problems.The author combines demonstration case to explain the application of the framework and provide teachers with operable path,so as to highlight students’ subjectivity and develop their mathematics thinking and core competency.更多还原
