I am a fervent proponent for modern constructionistic learning environments, but affecting change in the current system is almost impossible. Some teachers are enthusiastic and willing to spend their own time to develop and implement these modern* ideas about learning, but in the end, one way or another, they have to conform to the traditional educational system. If it isn't for management that presses for better test results, parents that want good grades, children that cannot take to the new way (for whatever reason) it is the seemingly incommensurability of these ideas with the traditional norm for education that leads to a watering down of the ideas and a feeling of hopelessness about it all.

What many don't understand is the enormous difference between the learning of the one child (your child) and the education of a nation. Try institutionalizing these "almost logical" ideas about learning for nation-wide implementation for a reasonable price and see what happens. I think it is possible to implement these ideas, but that means that we as a nation have to make hard choices. At the moment, we choose to fund education for all and learning for all be damned.

*: Every couple of decades these ideas or similar ideas seem to be reïnvented by a new generation ...
