I want to find out whether anyone has explored in a serious, systematic way whether educational leaders have taken into consideration changing demands on students' time relating to common activities in making policy decisions relating to graduation requirements, course selection, homework expectations, sports/phys ed requirements, club expectations, etc. and if anyone has meaningfully documented what those changing demands have been. My suspicion is that there has been little serious work in this area or, if there has been, that it has not seriously influenced policy decisions in both public and private schools, although it may play out differently in the two arenas.
Try Google Scholar to see if others have researched this topic. If they have not, and you want to do the primary research yourself, I'd suggest you track info from old books and newspaper articles. Start by picking 3-5 topics to track (eg time spent on homework), and create a simple tracking matrix showing each topic and various decades (eg 1970s, 1980s). Then try to find pieces from each different decade that discuss the topic. Maybe one article from 1984 will say that students often have 1-2 hours of homework a night. Another article from 1997 might report roughly 2 hours. Get 3-5 articles from each decade to make sure they are roughly consistent. If you can find a book or an academic article discussion what students face, it may give tons of info across several topics for that time period,and so might speed your efforts to fill in the matrix. May be slow going at first, but if you keep it simple, it's do-able. Good luck!
