It is the teacher's understanding of desired outcomes that guides students to the learning situations they need to visit. This is why understanding subject content and pedagogy is so important to teaching. If a student struggles with a concept, the knowledgeable teacher presents the concept from a different perspective or two perspectives, if needed, often changing teaching strategies. This kind of teaching only happens with teachers who know and understand what they teach and know how to motivate students to want to learn. A knowledgeable teacher with an array of motivational strategies tends to penetrate the thickest clouds of confusion and excite the least motivated students.
Good teachers produce good students.
A weak teacher produces weak students. The academic repercussions of weak teaching can haunt a student for a lifetime. Effective schools are successful because they depend on knowledgeable teachers and solid curricular strategies, both of which are essential to producing attentive, interested students. Education is about teaching, and teaching is about presenting ideas, facts, and concepts in a way that challenges students to learn. This process, though appearing simple, is challenging and complex.
