2. The _developmental_ (or inductive) lesson; in which the aim is to lead the child through his own investigation and thinking to use the information already in his possession as a basis for discovering new truth or meaning. 3. The _application_ (or deductive) lesson; in which the aim is to make application of some general truth or lesson already known to particular problems or cases. 4. The _drill_ lesson; in which the aim is to give readiness and skill in fundamental facts or material that should be so well known as to be practically automatic in thought or memory. 5. The _appreciation_ lesson; in which the aim is to create a response of warmth and interest toward, or appreciation of, a person, object, situation, or the material studied. 6. The _review_ lesson; in, which the aim is to gather up, relate, and fix more permanently in the mind the lessons or facts that have been studied. 7. The _assignment_ lesson; in which help is rendered and interest inspired, for study of the next lesson. THE INFORMATIONAL LESSON The child at the beginning is devoid of all knowledge of and information about the many objects, activities, and relationships that fill his world. He must come to know these. His mind can develop no faster than it has the materials for thoughts, memories, ideas, and whatever else is to occupy his stream of thought. He must therefore be supplied with information. He must be given a fund of impressions, of facts, of knowledge to use in his thinking, feeling, and understanding. To undertake to teach the child the deeper meanings and relationships of God to our lives without this necessary background of information is to confuse him and to fail ourselves as teachers. For example, a certain primary lesson leaflet tells the children that the Egyptians made slaves out of the Israelites and that God led the Israelites out of this slavery. But there had previously been no adequate preparation of the learners' minds to understand who the Israelites or the Egyptians were, nor what slavery is. The children lacked all basis of information to understand the situation described, and it could by no possibility possess meaning for them.
