Adults only learn efficiently when intrinsically motivated to master a specific skill or body of knowledge. They have a pragmatic learning approach and want to know how it will suit their present and future requirements. The learning objectives, learning style, and learning application are unparalleled. Adult learning enhances a dynamic and collaborative interface of reconstructed information that concurrently interfaces with internalizing external imprints of knowledge captured by various means. Stimulators of knowledge are faced with the Herculean challenge of conditioning the adult learners' minds since they must simultaneously foster a desire to study and augment the adults' knowledge base with innovative and novel techniques. The unidirectional knowledge flow that characterized conventional classroom teaching methods has already been challenged and overturned. Presently, lecture halls are furnished with technological tools to assist lecturers, whose clever approach and use of the tools bring out the learner's potential and promote interactive learning in lecture halls. With an andragogical approach, students are expected to make more in-depth connections between the supplied theory and the real-world situation. Innovative teaching methods encourage students to broaden their horizons beyond the expected job path and investigate the many avenues open to them. The paper presents innovative approaches to andragogy in contemporary higher education, especially engineering education.
