“…Core learning processes have been theorized in novel ways, such as conceptual change (e.g., in terms of catastrophe theory; Roth, 2014), knowledge construction (e.g., via a systemic-constructivist framework; Oeberst, Halatchliyski, Kimmerle, & Cress, 2014), complex systems learning (e.g., through the lens of activity theory; Danish, 2014), and the theory-practice gap (e.g., in terms of principled practical knowledge; Bereiter, 2014). Studies of learning across multiple levels of analysis have included Langer-Osuna's (2015) study of identity processes across microgenetic, ontogenetic, and sociogenetic levels; Akkerman and Bruining's (2016) study of boundary crossing at intrapersonal, interpersonal, and institutional levels; and Jurow and Shea's (2015) study of scale-making projects at individual and sociogenetic levels.…”
