“…Citing empirical research that explores goal orientations in PjBL learning contexts, Blumenfeld et al (1991) highlighted that when students adopt the notion that "learning is perceived and valued as an end in of itself " (p. 370), they are more likely to be motivated to learn and will engage in higher levels of cognitive and metacognitive stimulation. Despite the growing use of PjBL in K-12 educational environments, many researchers (Belland, French, & Ertmer, 2009;Catapano & Gray, 2015;English & Kitsantas, 2013;Krajcik et al, 1994;Tamim & Grant, 2013) acknowledge the pedagogical difficulties educators could potentially encounter as they implement PjBL, such as measuring learning outcomes over the course of the PjBL learning experience.…”
