We have just pulled our DD out of a play based curriculum school where the day is based around "investigations" and "authentic learning". I heard the academic who designed the curriculum talk, she was likeable and passionate but I left thinking "well sure, but if all that is true I can do it better myself by homeschooling." and it's not that i think her theories aren't valuable and interesting but I question the suitability for my DD in particular and for the population of a high fee / high socio economic area private school. Didn't work for us at all.
