“…In mathematics education, the term "abduction" is used to refer to a number of different processes and in relation to different activities. Abduction has been considered in relation to mathematical activity in general (see, e.g., Cifarelli & Sáenz-Ludlow, 1996;Krummheuer, 2007;Mason, 1996;Rivera, 2007), and it has been studied to explore ways in which it may be implemented in the mathematical classroom (Rivera 2017). Many researches have considered abduction in relation to mathematical proof (see, e.g., Antonini & Mariotti, 2003, Arzarello, Micheletti, Olivero, & Robutti, 1998Knipping, 2003, Pedemonte & Reid 2011Pedemonte, 2007Pedemonte, , 2008 to compare it with other forms of reasoning like deduction or induction.…”
