Celebrating Expertise in Mathematics Teaching: Insights from Dr Linda le Hanie
Improving the quality of mathematics education is becoming increasingly essential in South Africa, and one of the strongest influences on learner success is the presence of truly expert teachers. In the latest issue of Sum It Up! by Oxford University Press South Africa, Dr Linda le Hanie contributes a thoughtful and engaging article on this very topic.
Her piece, “Expert teachers in Mathematics: how to know one, how to be one,” unpacks the characteristics of expert teachers and offers practical guidance for those who aspire to grow their teaching practice. Rather than focusing only on techniques, Linda highlights the deeper thinking, decision-making, and professional habits that set expert teachers apart.
What Makes Someone an “Expert Teacher”?
Linda draws on the work of educational researcher David Berliner, who described five developmental stages of teaching expertise: Novice, Advanced Beginner, Competent, Proficient, and Expert. Each stage reflects a unique way of seeing problems, responding to learners, and designing learning experiences.
According to Linda, expert teachers:
One of her key points is that expert teachers think differently. They make connections quickly, anticipate challenges, and respond almost effortlessly in complex classroom situations.
A Voice of Authority in Mathematics Education
Linda’s contribution reflects her deep commitment to strengthening mathematics teaching across South Africa. Her work as a lecturer at SANTS Private Higher Education Institution gives her a strong understanding of both teacher development and real classroom experience. Her approach is always grounded in research, yet carried through with practical strategies that teachers can use immediately.
We are proud to share her insights with the education community and encourage you to read the full article in Sum It Up! for a richer understanding of her message.
