对学生的核心素养和高阶能力的培养是当前教育领域的热点话题。项目式学习是培养学生的核心素养和高阶能力的一种有效学习方式,深受基础教育者的青睐。然而,项目式学习在实践过程中面临着项目设计形式单一、过程性数据的收集与评价时间成本高且滞后、缺乏有效评价等诸多问题。基于证据的教与学强调教育教学活动的设计要遵循已被证实的研究规律;关注学生的学习过程,将学习证据与学生的学习状态建立联系;培养学生基于证据推理的能力,为解决当前项目式学习中存在的问题提供了一个思路。同时,证据中心的设计理论是指导众多高阶能力测评设计的理论基础,与项目式学习的目标相契合。因此,该研究结合大数据技术,将基于证据的相关理念引入项目式学习中,从教、学、评三个角度出发构建了证据导向的项目式学习模式,并以此为理论基础设计开发了证据导向的项目式学习系统,旨在为高水平的项目式学习的设计与实施提供支持,促进学生核心素养的发展。

The cultivation of students' core literacy and high-level abilities is a hot topic in the field of education. Project based learning is an effective way to develop students' core literacy and high-level abilities, which is favored by K-12 educators. However,in the process of practice, project-based learning faces many problems, such as single form of project design, high and lagging time cost of process data collection and evaluation, lack of effective evaluation and so on. Evidence based teaching and learning emphasizes that the design of teaching activities should follow the proven research rules; pay attention to students' learning process,and establish the relationship between learning evidence and students' learning state; develop students' ability of evidence-based reasoning. Therefore, it provides a way to solve the problems existing in project-based learning. Meanwhile, the theory of evidence centered design is the theoretical basis guiding the design of evaluation of many high-level abilities, which is consistent with the goal of project-based learning. Therefore, combined with big data technology, this study introduces evidence-based concepts into projectbased learning to construct evidence-based project based learning model from the perspectives of teaching, learning and evaluation.Based on this model, this study designs and develops the evidence-based project based learning system to provide support for the design and implementation of high-level project-based learning and promote the development of students' core literacy.
