I agree that students should FEEL the rhythm first, and that should involve the student's body.It's useless to try to make the student hear those metronome ticks if s/he doesn't have a strong feeling of pulse when asked to tap and say "quarter" for quarter notes. For some students, it helps if they swing their body, or walk or tap their foot. Something PHYSICAL has to be done. After this, the metronome could be introduced when playing a scale, as the student still says aloud "quarter" (and later "two-eights"). Believe me. This works! After all this, my student finally has a steady pulse and understands rhythm much better, even when playing Bach's sinfonias.
