No, I just completely forgot. Thanks for the thread bump, I'll get onto the reply now.
The British infant school, age 4-6, is just mandatory kindergarten. Polish kids in kindergartens do the same stuff. OK, it's not mandatory, still most children attend it.
I see that you have never taught at British schools: I have and that is why I know that British infant school is not mandatory kindergarten. I would direct you to the Learning & Development requirements of the Early Years Foundation Stage Framework. They include literacy requirements that 5 year olds should: readily use written language in their play and learning; use phonic knowledge to write simple regular words and make phonetically plausible attempts at more complex words; show an understanding of how information can be found in non-fiction texts to answer questions about where, who, why and how; begin to form simple sentences, sometimes using punctuation. There are similar levels of requirements for numeracy.
I've also taught Polish kids aged five: they can not read at all.
I suppose they do work more for one simple reason - they get homework assignments, which adds up to more hours of work a day than in the British system.
Good joke there. The current guidelines for homework in the British system state that children should start with one hour per week at the age of five (do Polish kindergartens give homework?) and build up until they are doing two and a half hours per day. However some leading schools commonly ask 11 and 12-year-olds to complete three or four hours' homework per day.
But, FYI, you can't do a magister in four years unless you are doing an individualised study programme. Normally, it takes five years. And yes, I believe that what can be done in six years can be also done in five.
So you agree that a Magister can be done in four years. OK, I agree: I know several people who have done their Magister in four years.
Where have I said anything about magister vs. Master's?
Would you agree that a Magister is not the equivalent of a Master's?
