Okami,
There is a huge gulf between elementary students that have had kindergarten and those that have not. It gets even more pronounced for those that have had bilingual kindergarten versus those who have not had any kindergarten. Free one year kindergarten was a great reform, but what are they teaching? I remember the initial start of this and it was glorified free babysitting. I'd assume it has improved. Private kindergartens give 2 years of Zhuyin Fuhao instruction and work with pronunciation. Good ones also work on hand strength and dexterity, key determinants of a good student.
By free kindergarten do you mean the ones attached to the elementary schools? It's not free, it costs about 20,000 for a semester, running until 4pm each day. Yes, there are subsidies for those who can't afford it, but subsidies are also available if you want to study in private schools. My son is in his second year of his kindergarten. Personally, I am very happy with this system. They do have a curriculum, the teachers are trained preschool teachers, and their activities are planned to work on those milestones in child development that are in curricula worldwide. The children also have a good amount of free time, which I now see was sorely lacking in the private kindergartens I worked in. Whilst they do introduce some pronunciation and the idea of it, they spend more time developing children's vocabulary, grammar and so on through stories, drama, songs, and other experiences (we could label it art, science...)
In a sense I would like to see it too, but the reality that without real reform at the basic school level, like more Zhuyin fuhao classes, your setting people up for failure or a hard time. I'll ask my anqinban today how much Zhuyin fuhao is taught in 1st and 2nd grade, but it's pitifully low amount of time in relation to its importance.
It was quite interesting to me, that the MOE wrote that actually Zhuyin fuhao is not as important as people think it is. They said, more time needs to be put into teaching children more vocabulary through experience, reading to them more for understanding, so they can understand their schoolwork better. Also, they talked about the difficulty of re-learning the pronunciation if it hasn't been taught accurately. (I don't have the booklet in front of me so I can't quote it exactly, I will extract some points, including the other questions, over the weekend.)
Okami, my nieces had 8 weeks of Zhyin fuhao instruction in first grade. That's pretty much all they did. That really seems enough to me, after that you have to spend time reading a lot of things to start learning the Chinese characters, such your written math problems, story books, and so on.
From the booklet, I felt that they were trying to stop people panicking and forcing their children to cram a lot of things into their minds before first grade, but rather let them get a balance of spending time with family, having shared experiences, or learning how to handle times when there is "nothing to do".
I know that a booklet won't change too much, but like sandman, I do see it as a small step toward at least starting people to think about the choices they make for their children.
