Message design is all around us, from the presentations in meetings and classes to the instructions with our latest tech gadgets to multi-million-dollar training simulations. In short, instructional message design is the real-world application of instructional and learning theories to design the tools and technologies used to communicate and effectively convey information. This field of study pulls from many applied sciences, including cognitive psychology, industrial design, graphic design, instructional design, information technology, and human performance technology, to name just a few.
