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

The correct answer is Providing complete solutions to students’ wrong answers.

Explanation:

In mathematics education, effective learning relies heavily on active problem-solving, critical thinking, and metacognition (understanding one's own thought process). Let us analyze how each option impacts teaching and learning in mathematics:

1. Enhanced quality of feedback: Providing timely, specific, and descriptive feedback helps students understand their misconceptions and guides them on how to improve their mathematical reasoning.
2. Using results of assessment to modify teaching: Formative assessment allows teachers to identify learning gaps and adjust their instructional strategies accordingly, directly improving learning outcomes.
3. Knowing ways in which assessment affected the confidence of learners: Emotional and affective factors, such as confidence and mathematical anxiety, significantly influence student engagement and success in mathematics.
4. Providing complete solutions to students’ wrong answers: Simply handing over ready-made complete solutions to students when they get an answer wrong reduces their opportunity to engage in productive struggle. Instead of analyzing their own mistakes, finding where their logic failed, and constructing knowledge independently, students passively copy the correct solution. Therefore, this practice is the least likely to positively impact deep teaching and learning in mathematics compared to the other interactive, feedback-oriented methods.

Hence, Providing complete solutions to students’ wrong answers. is the least effective strategy for enhancing mathematical understanding.
