Mobile learning is an evolving form of technology-based learning. The novelty of mobile learning gives educators a new tool for evaluating how to develop effective instruction for this new medium. A Delphi study was conducted using a 30-member panel comprised of experts across 20 states. The purpose was to determine the competencies needed to develop instructional strategies for mobile learning. The expert panel reached consensus on 48 competencies needed to develop instructional strategies for mobile learning. The competencies were grouped into 7 areas: communication, technology, learning, course management and policies, course content, assessment and evaluation, and instructor skills. Findings revealed the need for professional development to enable acquisition of these skills and also revealed the need to create a competency framework for the development of mobile learning. Instructors in colleges of agriculture using mobile learning can better meet the needs of their students when they possess the instructional design competencies needed to meet learners' needs. A lack of these competencies could lead to reduced effectiveness in the facilitation of learning overall when using mobile devices for instruction.
