The Logic phase involves ordering facts into organized statements and arguments. During the middle school years, children are beginning to think independently. They often develop a propensity for argument. Classical education teaches children in this phase to argue well. The study of formal logic helps students understand the fundamentals of a good argument. Practice in making written and oral arguments helps to further develop these skills. Teachers encourage the use of argumentation in each subject. Again, each subject has its own logic. In science, we use the development and testing of hypothesis. In math, we develop a student’s ability to logically orient numbers through the more abstract concepts of algebra and trigonometry.
