从知识到素养:真实性学习视域下的数学项目式学习设计

From Knowledge to Competency:Design of Project-based Learning in Mathematics from the Perspective of Authentic Learning

项目式学习作为数学学习的重要方式,是促进学生核心素养生成的重要推手,但目前小学数学项目式学习设计中存在不同程度的虚假性任务情境、虚假性问题解决、虚假性评价等困境。对此,应将数学项目式学习设计与实施置于真实性学习理论的视域之下,遵循以真实的社会生活和变化为基、以真实的数学实践和对话为核、以真实的身份和意义建构为本的理念,以趋向真实的问题情境为基础,以观念统整的真实任务为核心,以身心俱在的深度参与为根本,以技术支持的思维工具为支架,以作品导向的真实评价为保障,优化数学项目式学习设计的策略。

Project-based learning,as an important approach to mathematics education,is a driver for fostering students′core competencies.However,the current design of project-based learning in mathematics in primary schools have met various challenges,such as false task scenarios,false problem solving and false evaluation.In response to all these challenges,we should place the design of project-based learning in mathematics within the framework of authentic learning theory.To be more specific,we should implement the learning design based on real social life and changes,focus on authentic mathematical practice and discourse,and build concepts based on genuine identities and meaning construction.In addition,we should adopt strategies for project-based learning which starts from authentic problems in real life,focuses on concept integration in completing real tasks,evolves on deep engagement both physically and mentally,scaffolds with the technology-supported thinking tools,and guarantees with authentic assessment.
