Which of the following is least likely to impact teaching-learning in mathematics?

Simply providing complete solutions to students' wrong answers bypasses the learning opportunity in errors. Students don't engage in identifying their misconceptions or constructing correct understanding themselves. In contrast, enhanced feedback quality promotes learning, using assessment results to modify teaching is responsive pedagogy, and understanding the affective impact of assessment helps create supportive learning environments. Providing ready-made solutions has the least positive impact on meaningful mathematical learning.
