Project-based learning (PBL) is an instructional approach that utilizes student-directed inquiry processes to develop a product that has real-life connections and applications (Johnson, & Lamb, 2007). Specifically, PBL consists of inquiry-based tasks that help students develop important technological, social, and core curriculum content (Nastu, 2009). PBL has also been defined as a “special case of inquiry” (Slough & Milam, 2008, p. 19). Thus STEM PBL and inquiry-based learning go hand-in-hand in terms of student-centered instruction.
