Breaking up large classes into several smaller ones 61 (help) students, but the improvements in many cases come whatever teachers do, a new research suggests.
New 62 (finding) of the research from four nations, tell an interesting story. Small classes work for children, but that’s 63 because of how teachers teach, but because of what students feel they can do: get 64 (much) face time with their teachers, for instance, or work in small groups with classmates.
“These are the same as what researchers have already known,” Gamoran says. There is no good evidence 65 teachers change their instructions based on changes in class size. Teachers are always strict with their students. Some teachers are making use 66 small classes and others are not. There are a lot of differences. “It’s not like that you reduce classes so teachers do something different and the achievement is higher,” he says.
In one study, researchers 67 (close) watched students’ behaviours and found that students behaved better in smaller classes. They also 68 (have) more direct communication with teachers and worked more in small groups rather by themselves.
One team, 69 (lead) by Ronald Ehrenberg of Cornell University, finds that the potential benefits of class-size reduction “may be greater than what we observed” if only a few teachers change their teaching 70 (fit) the smaller group.
