In our work on the ADDIE instructional design we tried to identify our learning objectives as specificlly as possible and then put them at the begining of our design. We decided to incorporate various media such as Screencasting, discussion forums, video leactures to make the experince of learning as interactive as possible. Utilizing some short quizzes with the answers and explanations aftarewards, we tried to accomodate immidiate feedback in our teaching so that learners could identify their mistakes as early as possible. Apart from this formative assessment we also included summetive assessment in the form of a final poject. Unfortunately as this was our first experience in instructional design, it took us more time than we had thought to do our design and left the most part to be completed outside the class time which made collaboration between the team members difficult.
To me the most important phase of ADDIE model is the Analysis phase which defines the audience, their needs as well as the lesson’s outcomes and ways to measure its success. If the designers skips the Analysis phase they will not be able to fully address the needs of the audience and might design the course in a way which is not concordant with students’ abilities and need, i.e too easy or beyond the learners, resulting in learners’ boredom or struggle. If the analysis phase is not seriousley taken into account, the designer may even put inacuarate content in his or her design and therefore not teaching the correct material. This is a phase that once conducted with care, can prevent the potentioal errors that may occure in the last phase of ADDIE model which is the Evaluation phase.
In my oppinion the most difficult phase in ADDIE model is the Design stage where one should decide how to organize the content, in what ways deliver it, what type of activities and exercises to use that suit the various learning styles and how to measure the learners’ accomplishment. This is a stage that once done with care along with the Analysis phase, determine the difficulty of the subsequesnt stage which is the Development stage in which the course content and training materials are created to meet the needs of different leraners. The design phase requires logical and creative thinking on the part of the designer and acts as a blueprint for the Development phase. A good desing can fascilitate the Development stage and a poor one can easily slow down or hinder the process. I found the idea of using a concept map a very useful tool in the Designing stage as it helped us to brainstorm the ideas, break the information into chunks and organize them inlogically in our design.
Each model has its own advantages and disatvantages. One f the most common criticisms of ADDIE model is that the evaluation Phase is the last step in the design model which does not allow the prevention of the potential errors from the beginning. This drawback in the ADDIE model encouraged educators to revise the model in different ways. The picture below shows the most popular revised ADDIE model(clark 1995). ADDIE model
Another limitation mentioned is the mechanical and linear nature of ADDIE model. As opposed the holistic nature of f Dick & Carey and Kemp models. According to the article
Dick and Carey model breaks down the instruction into segments which allows the continious revision of th desgin and follows a more behavourial approach whereas the Kemp ID model emphasizes the management of the design process. The Dick & Carey model according to Moss is far better for beginner instructional designers and the Kemp ID will benefit the experience designers more.
