It's not surprising. Remember when you did complex algebra questions? in Lower Sec right? Now they are doing it in P6.
Remember when was the first time you used a calculator for maths? in Sec Sch right? now they are using it at P5.
It's very different now and if parents' dont't catch up, they'll be unable to coach their own children. My cousins are not well-educated (highest is o level onli), so they are unable to coach their own children. send them to me for tuition instead. all they are able to do is check that all homework is complete (based on the homework written down in the diary).
and to be honest, many tutors who are not taught this new syllabus are also stumped by the difficulty level (i have many tutor friends who will call me for help when they cant solve a problem).
and science coverage is getting larger. questions getting more tricky and require more application rather than knowledge. some children weak in english totally will not understand the experiment given in the question and will not do well even if they have the content knowledge.
and not only must you know the content, you must be able to apply. and you must be able to ANSWER THE QUESTION WITH THE RIGHT TERMINOLOGY. marks are not given if the correct terminologies are not used!
I have students whose parents are teachers and they themselves find it difficult to coach their own children. so for other parents, i won't be surprised if they are asking for help to coach their children.
i also have students whose parents sit in during tuition so that they can reinforce and coach their child when i'm not there (well, i'm only there for tuition once or twice a week, they still need to coach their child when i'm not there )
bottomline is education is getting tougher now. train your kids with study skills from young so they can cope with the demand. when they r curious, make use of the opportunity to teach them more, expose them to more knowledge and keep feeding their curiousity so that it will grow. when a child has a curious mind, the learning limits are endless
