They may appear keen to try these new ways and want to please you but do not be surprised if the next day or even sooner they go back to their old ways. This is because many of them will already have developed bad habits which, because of proactive habit interference , will get in the way of their attempts to learn new ways.
Old habits die hard.
Despite your best efforts, many children will be very slow to take up these desired new ways. They will appear to forget what you taught and showed them from one day to the next and will repeatedly fall back to old ways. This will happen even when they are motivated to improve. Conventional re-teaching will not help much with such learned errors or habit errors. You will need to use a Mediational Learning approach to help children unlearn their old ways so that they can more quickly adopt the new ways.
