“…Eleven studies looked at students' knowledge construction during mathematical modelling and mainly found that students are able to construct developing mathematical understandings (Arleback, Doerr, & O'Neil, 2013;Dunne & Galbraith, 2003;Hitt & Gonzalez-Martin, 2015;Lesh & Carmona, 2003;Lesh & Doerr, 2003a;Ng, 2011;Park, Park, Park, Cho & Lee, 2013). Six of the studies involved MEAs done in the U.S. in which students were able to reason with concepts of average rate of change with exponential functions (Arleback, Doerr, & O'Neil, 2013), inverse variation , proportionality (Lesh & Doerr, 2003a;, geometry and measurement (Lesh & Carmona, 2003), and transformational proof scheme that involves pictorial anticipation of an action not yet performed .…”
