There are those who think that segregation of the sexes is the answer to problems in education. They think segregation will end sexual harrassment in schools and put more attention on girls, one area in which our educational system has failed in the past. According to Jeffrey Weld, a biology teacher for eleven years, who is pursuing a Ph.D. in science education, segregating girls from boys in science and math courses makes no sense. Segregation of the sexes places the responsibility for closing the gender gap in education on the students, when the real responsibility lies with teachers, administrators, and parents, who can and should see to it that science and math are equally accessible to all students, regardless of gender. In reality, segregation of the sexes would only serve to reinforce stereotypes of what a female's role or a male's role should be in our society.
Class size has a lot to do with how a child learns.
If a child is in a class with thirty or forty other students, that child is definitely not receiving much individual attention from the teacher. It is not possible for one teacher to watch over thirty or forty students and give any special attention to an individual child who may be having trouble. Besides monitoring the behavior of a large number of students, the teacher is expected to teach effectively. It is no surprise, then, that some children fall through the cracks and fail academically. One step on the way to creating a better educational system would be to limit co-ed class size to a manageable number of students, a number that would allow for individual attention from the teacher when it is needed.
