I find that people outside of education often take for granted the tremendous thought and planning that goes into teaching. First, teachers have to figure out what to teach carefully reviewing curriculum guides and state standards. Then, they have to figure out how to teach. They need to break down those broad skills and concepts into manageable, bite-size chunks of information that are meaningful and developmentally appropriate for their students, and then, figure out exactly how to present that information in a way that will help their children learn. In addition to all of this, teachers are responsible for designing assessments that accurately measure their students' progress. Through the data gathered in those assessments, they are able to adjust their lesson plans and cater instruction to meet the needs of each individual student.
