QUESTION 1
Question 1.1: Essay on Moving Away from Traditional Teaching Methods in
Measurement (Intermediate Phase)

Introduction

Mathematics teaching in the 21st century is undergoing a vital transformation,
particularly in the Intermediate Phase. The call to shift away from traditional methods
towards learner-centered approaches is more urgent than ever. Traditional teaching is
often characterized by rote learning, rigid procedures, and a teacher-centered approach
that emphasizes memorization over understanding. In contrast, constructivist methods
encourage active participation, exploration, collaboration, and real-world application.
This essay critically explores the significance of adopting engaging and meaningful
pedagogies when teaching measurement, using constructivist theory as a framework.
Examples from personal learning experiences, curriculum interpretations, and
observations will support the argument.

Understanding Constructivism vs Behaviourism in Mathematics Education

Behaviourism, rooted in the works of Skinner and Pavlov, views learning as a
response to external stimuli. It emphasizes repetition, drills, rewards, and punishments.
