Introduction
Education in the twenty first century is passing through a time of fast change. Across the world, and especially in Africa, teachers are facing new demands from learners, parents, governments, and society at large. The classroom is no longer a place where the teacher talks and the learners listen quietly. Instead, it is now a place where learners are expected to think, ask questions, solve problems, and apply what they learn to real life situations. This change calls for new ways of teaching that can help learners gain deep understanding of concepts taught and perform well both in school and in life.
