We analyze in this study, from a pragmatic-cognitive perspective, the effects of algebraic, linguistic, and pictorial registers on the order and mobilization of possible and determined linear systems resolution strategies. In achieving this objective, we mobilize the theoretical notions of registers of semiotic representation (DUVAL, 2009, 2011), relevance (SPERBER; WILSON, 1986, 1995), and goal-conciliation (RAUEN, 2014), and conducted a two-step exploratory experiment. The first step was to propose that first-year high school students choose and solve three problems involving linear systems shown in algebraic, linguistic, and pictorial registers. The second step was to apply a verbal protocol to investigate the order and methods of problem-solving from the students’ perspective. The evidence suggests a predilection for pictorial and linguistic registers, superior—albeit insufficient—performance on these registers and abductive mobilization of less-than-formal strategies with different levels of mathematical knowledge performance including ad hoc creative solutions.
