基于项目式学习的数学教学研究

Research on Mathematics Teaching Based on Project-Based Learning

摘要: 本文聚焦于基于项目式学习的数学教学模型构建与实践应用。项目式学习虽能有效提升学生的学科素养，但在课堂教学中的应用仍面临诸多挑战。文章首先对项目式学习与项目式教学的概念进行了清晰界定，强调了学生在学习过程中的主动参与和合作解决问题的重要性。接着，文章基于任务型教学理论和合作学习理论，构建了一个包含项目选择、任务设计、成果展示和评价与反思四个核心要素的数学教学模型。通过长方体展开图的教学案例，详细设计了项目实施的各个环节，包括观看视频、问题引领、数据探求、模型完善和美育促学，旨在培养学生数学核心素养。研究结论指出，项目式学习对于学生掌握数学概念和提升核心素养具有显著效果，建议教师在教学中合理设置探究问题，转变教学角色，并采用多维度的评价方法。

Abstract: This paper focuses on the construction and practical application of mathematics teaching model based on project-based learning. Although project-based learning can effectively improve students’ discipline accomplishment, its application in classroom teaching still faces many challenges. Firstly, the paper defines the concepts of project-based learning and project-based teaching, and emphasizes the importance of students’ active participation and cooperative problem-solving in the learning process. Then, based on task-based teaching theory and cooperative learning theory, the paper constructs a mathematics teaching model which includes four core elements: item selection, task design, achievement display, evaluation and reflection. Through the teaching case of cuboid expansion diagram, each link of the project implementation is designed in detail, including watching videos, problem guidance, data exploration, model improvement and aesthetic education promotion, aiming at cultivating students’ core mathematical literacy. The research conclusion points out that project-based learning has significant effects on students’ grasp of mathematical concepts and improvement of core literacy. It is suggested that teachers should reasonably set inquiry questions in teaching, change teaching roles, and adopt multi-dimensional evaluation methods.
