The history teacher who wishes to make a success of the courses given must plan the work in advance according to certain common sense rules and conditions. In the first place, the extent of the subject matter to be covered must be carefully considered in connection with the time allotted for its completion, and the relative emphasis to be placed on the different portions of the period to be covered. Instead of a haphazard assignment of so many pages each day irrespective of time and subject matter, the length and character of the lesson assignments should be plotted out in advance. If the number of pages of text-book subject matter be accurately ascertained (many text-books have pages of outlines, review questions, references, and so forth), and compared with the number of recitation hours available, from which it is well to deduct one-third or one-fourth for reviews, a mechanical basis of assignments can be had. But a mechanical basis is not alone sufficient, a topical one is necessary also. This is the most difficult and at the same time the most vital part of organization and the part in which most teachers fail on account of poor perspective as to important and unimportant topics and a failure to realize the inner meaning and significance of the external events with which they are dealing. Fortunately most history text-books have been constructed on a skeleton of topics, and even a poorly-trained teacher can, with a little care, discover the proper lesson divisions. Some of the newer text-books go so far, indeed, as to give a series of lesson topics which the teacher can follow.[2] A competent history teacher, however, should not need to depend entirely on the text-book, outline, or syllabus, but should be able to select his or her own topics with judgment and success. A teacher properly trained to interpret the subject matter of the different fields of study who will take into account the length of time available and the extent of the text to be covered, can successfully plan out any desired course of study from beginning to end. This plan does not need to be absolutely rigid, but it will be a valuable guide for the work of the year or half year and will lead to a successful completion of the course of study. Instructors in normal schools and in college departments of education can easily train the students in courses on the teaching of history to make such topical outlines based on standard text-books. It will be time well spent, as the student will afterwards find in active teaching, as one such experience in enlightened planning out of a field of study will lead to competent handling of other fields.
