ADDIE+Model

__**SUMMARY:**__ ADDIE is a 5 step instructional model that allows the instructor to evaluate the learning process throughout the lesson.

The five phases of ADDIE are as follows: //Analysis// //Design// //Development// //Implementation// //Evaluation//
 * During analysis, the designer identifies the learning problem, the goals and objectives, the audience’s needs, existing knowledge, and any other relevant characteristics. Analysis also considers the learning environment, any constraints, the delivery options, and the timeline for the project.
 * A systematic process of specifying learning objectives. Detailed storyboards and prototypes are often made, and the look and feel, graphic design, user-interface and content is determined here.
 * The actual creation (production) of the content and learning materials based on the Design phase.
 * During implementation, the plan is put into action and a procedure for training the learner and teacher is developed. Materials are delivered or distributed to the student group. After delivery, the effectiveness of the training materials is evaluated.
 * This phase consists of (1) formative and (2) summative evaluation. Formative evaluation is present in each stage of the ADDIE process. Summative evaluation consists of tests designed for criterion-related referenced items and providing opportunities for feedback from the users. Revisions are made as necessary.

__**HISTORY:**__ Although several sources claim that there is no known author or creator of the ADDIE model, W. Dick and L.Carey are credited for refining the model to what it is today. Here's a timeline on the evolution of the ADDIE model.
