M.8855 is a technology-based instructional design and implementation guide that was created by the American Center for Technology and Education (ACTE). It contains a set of instructional design standards, concepts, and philosophies that make up the framework for designing, implementing, and assessing technology-enabled learning experiences. The guide includes six core activities—analysis, design, development, implementation, evaluation, and sustainability—that make up the instructional design process. The activities are broken down into smaller tasks and resources that can help those working in the field of instructional design to focus their efforts and ultimately create the best learning experiences possible.
