So it looked as though teacher motivation and teacher migration was a powerfully correlated thing with what was happening in primary schools, as opposed to whether the children have enough to eat, and whether they are packed tightly into classrooms and that sort of thing. It appears that way.
つまり 教師のやる気や定着率が 初等教育での成績に 大きく関連しているのでしょう 子供が十分に食べているか 教室にぎゅうぎゅう詰めにされていないか というようなことは関係ないのです
