“…In DBR, innovative educational systems are deployed in naturalistic settings while, simultaneously, experiments studying the innovative systems are systematically conducted (A. L. Brown, 1992;Collins, 1992;Sandoval, 2014). Through iteration, instructional designs are improved and theoretic conjectures are refined, that is, design of instruction and research on learning intermingle (Bakker, 2018;Minichiello & Caldwell, 2021). Like engineering design, itself, DBR uses a systems approach to create useful innovations within real constraints (Hjalmarson & Lesh, 2008; for examples of DBR studies in engineering, see Dasgupta, 2019;Newstetter, 2005).…”
