what i find with a lot of international school/ ESF school kids just focus on rote learning these days. a lot of the better teachers left hong kong left hk i the last ten years and now they are just left with people that don't know how to teach! instead of gaining critical understanding of the material they just rote learn instead. a lot of parents are aware of the teaching quality out here in HK but what can they do? they are stuck in hk because of their jobs afterall... so they look for private tutors for their kids... even though a lot of these tutors claim to know the international curricula well- they actually went to local schools here in HK so they are just another bunch of rote learning robots.
in my opinion, you cant put too much faith in the schools anymore, and start looking for a tutorial centre that focus on holistic learning and gaining critical understanding before your kids turn into robots!
