In 2002, Netty Baan started her teacher training in Pass Valley, located sixty kilometers from Wamena, deep in the Papuan inlands. During a two-year period she taught a two-monthly course to a group of 25 primary school teachers. She aimed to teach them new skills that would make teaching more fun and effective. In the mornings she taught new theory which the teachers put into practice in the local elementary school in the afternoons. It was successful to a degree, but Netty was not satisfied. It is hard to change ingrained habits overnight.
