1. some mummies themselves are not equipped with study techniques to teach their kids
2. to teach time management, you need someone to guide them first. many parents dont have this luxury to sit at home to remind your child when it's time to do something
3. teaching them self-study skills does not show immediate results. many parents want immediate improvement in results
4. the kid must be mature enough to understand the need for self-study. many kids do not understand the need to study, therefore they do not focus on it
when i give tuition, i do teach the kids time management and self-study techniques. everyone is different so the kids gotta learn to discover their own unique way of studying. some kids can use mindmap very well to study, some kids need to read many times, some kids need to write many times to be able to remember basic facts. basically it's a discovery process which may take quite a while for the child to discover his/her own best study technique.
it's easy to 'say' but when put into practice, it really takes alot of effort. it's easier to just 'baby' them thru the education system which would be what most parents would choose to do bcos they do not know how to go about imparting these lifelong skills to them. most children will be able to discover their own self-study methods by the time they are in sec sch.
*this is the reason y expensive motivation n study skills courses which can costs thousands are always full n even have long waiting lists. parents understand the need n importance, but how many parents are able to guide their child on their own without the knowledge and time?
