No two students who walk through the music room door for a lesson are the same and I like this quote because it emphasises the individual first before the material we are about to teach them.
Every student is unique. They might be young or old, different genders, from different cultures or perhaps have learning needs. They could also have contrasting learning styles, whether that is visual, more aural based, a preference for practical based activities (a kinesthetic learner) or even a combination.
So even though you might be teaching students Ben and Emily the same version of 'Twinkle Twinkle Little Star' in their tutor book for example, the approach is likely to be different for each individual.
How do you personalise or tailor the teaching to each of your students and do you agree with the quote?
