Yeah, probably no recess either.
These kids are being used as Janet's little guinea pigs.
I remember when I was homeschooling my kids.
They began at age 4 1/2 and we probably did a total of one hour max of schooling per day. The rest of the day, I wanted them to be kids--playing.
Now that my kids are in high school, I can look back and say I did nothing detrimental at that age that would produce poor school performance.
I read the study and couldn't tell if race/income etc. were controlled--what if full-day Kindergartens tend to be popular in poorer neigborhoods, or neighborhoods where both parents work, for example?
I'm not strongly for or strongly against all day K, just wondering about this study.
