Teacher's Goals
Teachers have goals, called lesson plans, for each of their classes. For example, how do you teach students about the metric system if they have never been exposed to the concept? A lesson plan is a step-by-step breakdown of how the teacher plans to accomplish this task. Then, how do teachers measure how well you are learning the material?
You guessed it. Tests, quizzes, class participation and term papers are the tools they use to measure their success. They tell the teacher if your class needs further review or can move to a new topic.
