Half Time Cyberteacher

How to solve the shortage of teachers. Some school subjects such as math practise, might be cut in half using a  computer as the supervising teacher. Same with homework. When it comes to quizzes, memory tests, and writing work all might be checked by a computer with results sent to the instructional teacher.  It would free the student to do such work at home rather than attending a school building. Teachers are there to consult in a student's education,  instructing and conselling young people. Practice in a mechanical way, doesn't require an instructor. I think of one teacher who persists in demanding that students do a list of algebra questions every night as homework. That doesn't make sense to me when the student rebels with "I know how to do this, why do I have to take my time going over and over it". Overcrowded schools and lack of  teachers might also be helped in this manner. It is not a bizarre suggestion. How much of a teacher's time is spent in actual instruction and how much in monitoring quizzes and supervising students who are writing only or reading material or filling in blanks or doing work sheets? Sometimes, a computer testing is less threatening for some students who would benefit it done by a computer. Computer progams have an objective way of correcting student errors and in a non threatening way, re-teaching until the student gets it right. Sounds odd,  but in my teaching career I found that certain students work better with a computer than in a busy classroom where social issues might interfere. A teacher in this situation, would be available when the student needed to consult or question. It would allow one teacher to attend a larger number of students, therefore. While it may be argued by some, to be non-education, we all know perfectly well, that students learn a great deal on their electronic devices because we are creatures whose brains are memory banks in themselves and they learn best in images as well as symbols such as letters of the alphabet and certainly by repetition. Time away from mechanical practise would be better spent in the arts for example: graphics, musicl, dance, performance etc. Parent and student would make a personal choice outside,  instead of having it happen within schools. The teachers who trained for these subjects in the the arts, could then become paid business persons in their artistic  subjects rather then under school district oversight. Those parents who couldn't afford the arts sessions, would be assessed to be government subsidised. Arts teacher talents would become private business. It would mean,  back to the future in the public schools once again: places for "reading, writing, and arithmetic".  Just a thought.
