Scaffolding Content and Process in PBL

There are multiple paths babies take when learning to walk. Some babies skip crawling altogether and cruise from object to object. Others use the support of a bouncy chair or walker, or take tentative steps holding the hands of a loving adult. The age at which children are ready to walk varies, as does the process that helps them get there. Over time, with the addition and subsequent removal of the right supports at the right moments, most kids gain confidence, stability, strength, and independence and learn to walk with ease, grace, and automaticity.
