Children in these member schools are not inert. I'd just say anything. Whatever came into my mind, I would just say it. No one would really laugh at you if you would be wrong. Over here, everyone would speak out loud.
Classrooms reflect the educational approach of member schools.
Several activities thus might be going on simultaneously in the same classroom. Educational projects are organized in such a way that children learn that all intellectual pursuits are interconnected. These portfolios are presented to committees of individuals inside and outside the school, i.e., other educators. Portfolios are better than tests. Even if you cannot do something in portfolio, you ask someone for help, you ask for explanation, and you still put it in your own words, you're still writing it yourself.
