We often think about schooling as simply getting good exam results; maybe at best, we regard it as a way to practice our intellectual skills. But schools are where the adults of tomorrow learn not just how to read and write, but how to live. Our schools do a good job of teaching us basic literacy (and arguably quite a poor job of helping us think about the things we read and write), but even our best schools are often only mediocre when it comes to preparing us for life outside academia.
A friend of mine, Lim Su Ann, wrote an excellent post some months back on how deeply unsatisfying the opportunities for extracurricular growth are in our schools — it's a piece I recommend highly. Most of us in school simply go through the motions of extracurricular involvement — we don't really care about what we do. Most of the extracurricular things I pursued in school had nothing to do with my school. Until our schools allow students the freedom to pursue the things which interest them outside the classroom, and encourage responsible decisionmaking instead of simply usurping all of students' autonomy, we can't say our schools are properly preparing the adults of tomorrow.
