Query: An informal guide to informal learning

Do people learn best by sitting in a classroom taking notes? Not according to "eLearning" expert Jay Cross. Instead, he says, companies should champion nontraditional, informal learning methods, including: "unconferences," "unworkshops," "eLearning," "Courageous Conversations" and even "grokking" (sci-fi writer Robert A. Heinlein's term for "instantaneous, holistic recognition" or understanding). Cross says properly presented informal learning programs can give your firm a better return on its training investment than formal learning. He explains why that is and how to use his approach. Despite some repetition and fluffy filler, getAbstract recommends this book to learning officers, training managers and human resources professionals who want to know more about setting up informal learning initiatives.
