This paper discusses the development of a learning approach based on the unique needs of adult learners who are required to learn and use new information technologies. It establishes how the "Inquisitivism" learning approach has evolved from a synthesis of key cognitive learning theories into one cohesive approach and how the implementation of Inquisitivism in the development of learning environments, curriculum, and courses can meet the needs of today's adult learner. The first section explains why there is a need for a new approach to adult learning. Contemporary cognitive learning theories upon which this new approach is based are identified in the next section, including constructivism, discovery learning, activity theory (active learning), functional context, and minimalism. The third section describes the learning approach of Inquisitivism. The following key concepts of Inquisitivism are summarized: (1) fear removal; (2) stimulation of inquisitiveness; (3) using the system to learn the system; (4) getting started fast; (5) discovery learning; (6) modules can be completed in any order; (7) supporting error recognition and recovery; (8) forum for discussions and exploiting prior knowledge; (9) real world assignments; and (10) developing optimal training designs.
