Leading Learning: International Perspectives Book

This is a pretty dry read, but the info is useful. The authors advocate for longer school days to bring such benefits as increased arts and language instruction, longer class periods for in-depth study, and tutoring to improve students' proficiency.

For society in general, it would be awesome if kids had more time for learning skills and were kept off the streets/out of trouble for more hours of the day. Personally, though, I'd like less institutionalized school time for my children, allowing more time for learning alone, having family fun, and just being creative.
