My professor told us that reading is silent by nature
but, in the class, we resort to aloud reading to check students' pronunciation and see who of them has dyslexia. In fact if they are unable to read or confuse some letters like (d-b)or words like (saw-was) they won't understand well.
hey
i sometimes use shared reading to encourage my students and help them have some confidence in themselves, they really like this way.
