Her reflections indicate a shift to this pedagogical approach, which tailors the intended mathematics and classroom activities to students’ available conceptions. The data reflect how, via professional development, her new understanding of students’ learning to reason multiplicatively promoted learning opportunities for them and thus ‒ their outcomes. We discuss how linking teacher development to student conceptions ‒ aptive pedagogy ‒ can contribute to improving their outcomes. rv:
