The Logic (or Dialectic) Stage
Grades 6 - 8
During the dialectic stage the student’s capacity for formal reasoning develops. So why not stick the peg where it fits? This is the stage when learning facts is not enough. Questioning and arguing is commonplace, and often even a nuisance. Children reaching this age are eager to challenge ideas and exercise their newly developing reasoning abilities. Learning formal logic and the correct methods of reasoning fit in this stage like hand-in-glove. Logic, as a subject, matches the structure of their developing minds. Amazingly, classical and Christian schools have been quite successful in teaching college level logic to eighth graders (including formal syllogisms, fallacies, truth tables, and digital logic)!
