The document describes the ASSURE model of instructional design. ASSURE is an instructional systems design (ISD) process modified for use by teachers in the classroom. It incorporates Robert Gagne's events of instruction to ensure effective use of media in instruction. The steps are: 1) Analyze learners, 2) State standards and objectives, 3) Select strategies, technology, media and materials, 4) Utilize technology, media and materials, 5) Require learner performance, 6) Evaluate and revise. The model provides a systematic approach for teachers to design lessons that meet learners' needs and help them achieve learning objectives through strategic use of appropriate materials and technology.
