“…The totality of correct answers associated with the mixed strategy (solving procedures and explanations that emphasise both the use of scalar relationships and functional relationships) is worth mentioning because it suggests that when using this strategy, students consider the multiple relationships present in the problem statement. These students make use of action schemes that involve both scalar operators and functional operators, considering the various relationships in double and multiple proportion problems (Lautert & Schliemann, 2021;Nunes & Bryant, 1997;Santos, 2015;Vergnaud, 2009).…”

“…Each one has specific characteristics and forms of resolution, which mobilise different reasoning, depending on its configuration. (Gitirana et al, 2014;Levain, 1992;Lautert et al, 2017;Levain & Vergnaud, 1994/1995Vergnaud, 1983;1988;2011).…”
