Society is changing. Technology is changing. Therefore, it seems a logic conclusion that how we learn and what we learn, from the onset, changes. I feel the people complaining (educators and teachers association) that kids aren't learning how to play with blocks are more concerned about preserving their existing jobs rather than adjusting to a changing world.
That doesn't mean I think learning to play with blocks, lincoln logs, or lego is wrong or outdated. I think the complaining by the teachers association is just that...complaining.
