Providing teachers' aides in more classrooms would improve educational quality by allowing every student to get help or assistance during class. Sometimes so many students have different questions that the teacher cannot get around to everyone before the class period ends. With teachers' aides, most of the students can get their questions answered. The last idea to improve education is to perform teacher evaluations at least twice a year. An administrator or appointed evaluator could drop in the class unexpectedly and observe teachers.
Some teachers are lazy.
Some just don't know what they are doing, or at least it appears that way. Teacher evaluations will be a tool for disposing of those incapable teachers, and making room for qualified ones. Adding classroom discussion to the curriculum, getting rid of disruptive students, putting more teacher's aids in the classroom and conducting teacher evaluations are all ideas to improve education quality.
