4. Do you make a reasonably complete and wholly definite lesson plan for each lesson? Do you keep a plan book, so that you may be able to look back at any time and see just what devices you have used? If you have not done this, will you not start the practice now? 5. What type of lesson material do you use, uniform, graded, or textbook? Are you acquainted with other series or material for the same grades? Would it not be worth your while to secure supplemental material of such kinds? 6. Do you read a journal of Sunday school method dealing with problems of your grade of teaching? If day-school teachers find it worth while to read professional journals, do not church-school teachers need their help as much? If you do not know what journals to secure, your pastor can advise you. FOR FURTHER READING Strayer, A Brief Course in the Teaching Process, chapter XVI.

None but lasting impressions possess permanent value. The sermons, the lectures, the lessons that we remember and later dwell upon are the ones that finally are built into our lives and that shape our thinking and acting. Impressions that touch only the outer surfaces of the mind are no more lasting than writing traced on the sand. Truths that are but dimly felt or but partially grasped soon fade away, leaving little more effect than the shadows which are thrown on the picture screen. Especially do these facts hold for the teacher in the church-school class. For the impressions made in the church-school lesson hour bear a larger proportion to the entire result than in the public school. This is because of the nature of the subject we teach, and also because of the fact that most of our pupils come to the class with little or no previous study on the lesson material. This leaves them almost completely dependent on the recitation itself for the actual results of their church-school attendance. The responsibility thus placed upon the teacher is correspondingly great, and requires unusual devotion and skill. ATTENTION TO KEY The things that impress us, the things that we remember and apply, are the things to which we have attended wholly and completely. The mind may be thought of as a stream of energy. There is only so much volume, so much force that can be brought to bear upon the work in hand. In attention the mind's energy is piled up in a "wave" on the problem occupying our thought, and results follow as they cannot if the stream of mental energy flows at a dead level from lack of concentration.
