We can interpret that this PPT understands global generalization to be a “functional relationship,” since in describing the strategy of problem 1 he/she states: “the student realizes that on top there is always one more square than in the lower row, where the number of squares tallies with the number of the figure.” Moreover, the PPT states that although in all three problems the student found the “overall pattern” (functional relationship), in problem three he/she did not “apply it the other way around” (inverse process), which he/she understands as “the reverse operation to the one carried out before.”
