This is our multistory approach to ensure that the basic doctrine is learned. This is often confusing to many teachers and they can be shown how this is done. Some churches or parents want to use these materials as the basis for their family devotions and want to know the best way to do this. Many times churches want to train new teachers in skills such as classroom discipline, teaching songs, learning how to put the Gospel into every lesson, and other 'basics' that this seminar covers. The seminar can be adapted to meet unique needs of the audience that it is teaching.
All teachers can become tired and sometimes discouraged.
The answer to this question depends on the church asking it. Each situation is unique and therefore the seminar is molded and conformed to meet the specific need of the group asking for it. The 10 reasons listed above help to explain it. As Protestants, this is one of our heritages. If a church wants a basic teacher's seminar we will send the leadership the outline that we generally cover.
