The ADDIE Model - Why to Use It - Essay Example

Activities of the Model:

            As explained earlier the ADDIE Model is comprised of five main stages (Tzanis, 2002). Here the main activities of these stages will be discussed.

1. Analysis: This is the first phase of the model. Here the main problem is defined and the sources of the issue are identified. The source of the issue is then used as a means to determine the possible solutions. This may include a wide range of techniques like a job or task analysis (Castagnolo, 2007). Here the output from this phase generally provides the instructional goals and these are used as a start for the design phase.
2. Design: This stage is based on the analysis stage and here this stage involves the development of the plans to reach the instructional goals. This stage involves a number of activities like the selection of delivery systems, learning analysis, population description, and also listing of the objectives.
3. Develop: The third phase of the model is the development stage. Here the focus is on the development of the instructions and also the use of various media and documentation to help develop the plans. This stage involves activities like generation of the lesson plans and also lesson materials.
4. Implement: This stage as the name suggests is the actual delivery of the instructions. Several activities can be involved here including different mediums of instruction like classroom learning, lab-based, or computer-based learning.
5. Evaluation: Finally the last stage of the model is the evaluation stage. Here this occurs among all the phases and even between phases. This stage can be divided into two main phases. Formative Evaluation and Summative Evaluation. The first form is done during the ongoing and between phases, while the summative evaluation occurs during the final element of the implementation. The activities that are included here are the decision-making processes like whether or not the instructional package should be bought if it should be continued or discontinued.

Essential Stages:

The most essential stage among the above-mentioned stages is the analysis and evaluation stages. The analysis stage is the most essential as it brings out the overall scope and goals and also brings out the changes needed. Any mistake here at this stage can lead to wasted efforts (Branch, 2009). In terms of the evaluation stage, this stage is also crucial as it takes into account all the processes and ensures that the processes are accurately completed and meet the actual plan. Here it is important to note that although each of the stages is important in its own manner, these stages form the foundation of the ADDIE model and hence need the most focus.
