What is Pedagogy?
Pedagogy is the art (and science) of teaching.
Effective teachers use an array of teaching strategies because there is no single, universal approach that suits all situations. Different strategies used in different combinations with different groupings of students will improve learning outcomes. Some strategies are better suited to teaching certain skills and fields of knowledge than are others. Some strategies are better suited to certain student backgrounds, learning styles and abilities.
Effective pedagogy, incorporating an array of teaching strategies that support intellectual engagement, connectedness to the wider world, supportive classroom environments, and recognition of difference, should be implemented across all key learning and subject areas. Effective pedagogical practice promotes the wellbeing of students, teachers and the school community - it improves students' and teachers' confidence and contributes to their sense of purpose for being at school; it builds community confidence in the quality of learning and teaching in the school.

Why is it important?
Pedagogy is the "how" the teaching and learning occurs. Students are not empty vessels to be filled with our expert knowledge. They must construct their own understandings through our considered learning experiences.

Do I need variety or do I need consistency?
The answer is both. Students need to feel safe to learn effectively. You need variety in order to reach all the students in the class. Therefore a wide variety of teaching strategies are essential in order to develop effective methods of teaching at the highest level.
