Fermilab is a U.S. Department of Energy national laboratory for research exploring the fundamental nature of matter and energy. This paper describes the Fermilab LInC (Leadership Institute Integrating Internet, Instruction and Curriculum) Online program and the strategies used over the past six years to develop leadership teams that can: (1) recognize, design, and implement engaged learning experiences for and with their students based on local, state, or national standards; (2) effectively integrate technology in these experiences to allow students to communicate, collaborate, explore, research, and publish in ways that would not be feasible without the technology; and (3) provide professional development and act as change agents in their region. LInC has developed and refined a wide variety of scaffolding strategies to assist K-12 educators in making the transition from traditional lecture-based teaching to technology-supported engaged learning. LInC has also created a successful online course by developing online strategies to maintain and improve upon essential qualities of the original face-to-face course. Contains 7 references.
