The topic / subject line caught my interest. I evaluated several schools from this perspective couple of years back and found a school called Babaji Vidhyashram in Sholinganallur. Both my kids study there now. It may be worthwhile investigating. The only negative is they are the only school on OMR where you cannot get admission if you are not well planned, in line with their philosophy and well planned ahead of time.
Thanks for your message PB. If you don't mind could you share your contact (mail/phone) to discuss on this? You can message me at email@example.com
You can also consider Montessori schools which makes children learn beyond books.
