教师要充分利用好“同学”这个教学资源。这样,既能增加师生互动、生生互动的机会,又能让更多的学生从中得到启示。最后本人和同伴都没有发现和意识到的错误由教师来订正。学生本人、同伴和教师的共同纠错,形成一个整体,这就是“三位一体”纠错法。 Teachers should make full use of “classmate ” this teaching resource. In this way, it not only increases the chances of teachers and students interacting with each other, but also enlightens more students.
