This is an argument advanced by Burgerstein (524 ff.) against coeducation in the German middle schools, and it is worthy of serious consideration. For the rest, the relations between sex and fatiguability are still quite as uncertain as those between intelligence and fatiguability. The greater susceptibility to fatigue of younger children is to be met by shorter lesson-periods, fewer hours of study and more frequent pauses, particularly in the primary grades. Length of lesson-periods. In dealing with the mat- ter of the length of lesson-periods we may as well see clearly at the start that human nature gives us no absolute warrant whatsoever for making a lesson- period exactly an hour, exactly 60 minutes.
