Project-based learning (PBL) offers many advantages in classes that enroll HL learners. Among these, it builds on the linguistic and cultural strengths of HL learners, supports the development of functional proficiency through real-world language use, and facilitates learner-centered instruction. This workshop will present the principles of PBL and the steps of project design, including assessment and classroom strategies for working with authentic materials and differentiating instruction. In addition, sample projects will be shown and adaptations for learners of different ages and proficiency levels will be discussed. Participants will identify possible project themes, driving issues, and products for use in their own teaching.
