Core Practices for Project-Based Learning offers a framework and essential set of strategies for successfully implementing project-based learning (PBL) in the classroom. Centering on teaching practice, this work moves beyond project planning to focus on the complex instructional demands of the student-centered PBL approach. Pam Grossman and her colleagues draw on their research with teachers, educational leaders, and curriculum designers to identify the instructional goals, practices, and mindsets that enable educators to effectively facilitate deep learning in PBL environments. The authors guide educators from a clear starting place through a series of concrete, manageable steps that apply whether they are initiating PBL or working to improve the quality of existing PBL implementation. Extended case studies illustrate the use of the core practices in real-world situations.
