Our education system

After spending a few years now in education - i am fast coming to the conclusion that our system of education is a bit back to front. My primary reason for thinking this is that from an early age in rimary school we engage students in whats seems to me in thematic based work where the primary curriculum allows teachers to explore content in a combined way. Whilst when the students get to secondary school we put them in silos seperate subject knowledge and traditionally expect them to learn in 5 or 6 50 min periods.

This creates a real dilema in that we expect students to be able to work independently and make decisions but the way we teach them promotes students who sit and digest learning rather than being active participants in it. It would seem logical to me that at an early age we teach students to make decisions and learn processes in a systematic/ more structured way whilst at secondary level giving them space work at a more independent level
