"People become ready to learn something when they experience a need to learn it in order to cope more satisfyingly with real-life tasks and problems. The educator has a responsibility to create conditions and provide tools and procedures for helping learners discover their "needs to know." Learning programs should be organized around life-application categories and sequenced according to the learners' readiness to learn."
