Abstract:
We analyzed the written answers and explanations by high-school students who attempted to solve double and multiple proportionality problems using the cross-product algorithm. We focused on students’ awareness of the scalar and functional relations among the quantities described in verbal problems, an aspect that has been part of their school instruction.
Keywords:
Cross-product algorithm; Double proportionality problems; Multiple proportionality problems; Scalar and functional relations
