hmm....all govt-schools in SG, all teachers (except for mother tongue teachers) adhere to EL mode of communication when comes to teaching.
teachers and students are not the only factors to consider. There are other internal and external factors that you have to take into consideration to ensure that the child picks up good command of EL.
frequent oral/written practice at home,
lang. people use in the presence of the child,
setting up of home environment (like EL books for the child, EL tv prog)
IMHO, it is not to fair to put the sole responsibility on schools, school friends and teachers in educating our children to learn EL. A good foundation starts from home.
