A praxis rationale evolved during the development of the Compendium over a period of several years. In general, educators of adults have two options for helping adults learn. One teacher-oriented option is an instructional perspective for knowledge transmission familiar during secondary and higher preparatory education for young people who share similar preparation, and use achievement exams to demonstrate successful completion, but whose actual performance occurs later in various life roles and contexts. A second praxis option is life-long, life-wide, and life-deep collective learning by educational program participants, instructors, mentors, coordinators, evaluators, media specialists and other program stakeholders; focused on enhanced performance in roles such as family, work, community, recreation (team, music); that entail combinations of knowledge, skills, and predispositions; along with situational influences or simulations. The second option is the focus of Learning Performance.
