They need to prepare lesson plans, make up and mark tests and assignments, write out report cards, valentines, Christmas and thank-you cards, etc. Lesson plans are a particularly important component of teaching. Without them there would not be any order and coherence to the school day. When a teacher comes to class unprepared, it is the students who will suffer. Although a degree of spontaneity in the classroom is desirable, teachers need to get the daily curricula covered in order for their students to be able to move smoothly through their studies.

Guidance is not provided on a regular basis and this arrangement could prove trying to individuals who feel that they need to be helped along.
