In this essay from a teacher in Argentina, Valeria Vincent describes how she employed Multiple Literacies in Project-based Learning (MLPBL) (Krajcik, Palincsar, and Miller 2015). ML-PBL, an open education free resource, has three design principles that support teacher and student learning and satisfaction. ML-PBL builds on teacher ingenuity and adaptation (Miller, Severance, and Krajcik 2021; Miller et al. 2021) rather than prescription through contexts where both students and teachers play, create, and learn (Charara, Miller, and Krajcik 2021). Some of the challenges included finding materials that can work for designing investigations and sharing artifacts. For example, classroom and recycled materials are different in Argentina. In addition, the "Next Generation Science Standards" (NGSS) are more comprehensive than the science standards of Argentina. The NGSS are foundational to ML-PBL, as three-dimensional standards expand learning opportunities (Ford 2015; Severance 2016).
