When visiting a village, consider asking if you can be shown around the local school. If in session, observing the ways of the students and their teacher will be instructive. (Though you, of course, will be a distraction.)
If out of session, there will still be things to learn. Posters like this one on the wall will likely remind you of your own grade school, with a twist.
Other features, such as the hand-lettered sign painted on a piece of metal at the entrance of this school, stating in plain blue letters "AIDS IS OUR ENEMY FIGHT IT" lets you know some young students have a lot on their minds. And the posters in other classrooms using cut-out magazine pictures to help illustrate how HIV is transmitted, lets you know they are being taught how to do something about it.
