Too much homework?

In my country has emerged a new debate. Do the Spanish students have a lot of homework? I could say a big yes a long time ago but my work colleagues do not agree. The pupils in Spain can have between one to three daily hours of homework outside the exam period. They have six hours at school and other three hours at home. Nine hours in total. Their fathers work less.
The teacher says that the effort is important. This reminds some teacher of an old school. In my country the people say "the letter with blood enter" and they follow thinking the same thinking.
We need a deep changes in our education. Maybe we can look at other countries with new education systems, better and more humanitarianism.

[Good work.]
