The ADDIE Model utilizes 5 phases.

# data[].attributes.body
The ASSURE Model utilizes 6 phases.

# data[].attributes.body
The Four Door Model utilizes 4 different learning environments.

In this model, each step has an outcome that directly feeds into the next step.

# data[].attributes.body
In this step the instructional problem is clarified. Educators determine goals and learning objectives. Students existing knowledge and skills are evaluated here, much like in the ASSURE Model.

# data[].attributes.body
In this step, the learning objectives are identified, assessment instruments are selected, exercises are determined, lesson planning and media selections are made. Each element of the unit must be hit during this step.

# data[].attributes.body
This is where the unit is fully developed. Educators create and assemble the content.

# data[].attributes.body
During this step, the course materials and curriculum are delivered to students. Educators start to see learning outcomes.

# data[].attributes.body
This step is where students are evaluated. Educators will use formative and summative assessments. This step is a little different than in the ASSURE Model because educators don't "revise" like they do in the ASSURE Model.

# data[].attributes.body
Overall, I think the ADDIE model and the ASSURE model are the most closely related. They have a lot of steps that demonstrate similar procedures for teachers. However, they differ a little in specific details. The biggest difference, I feel, is that the ASSURE model requires learner participation, whereas the ADDIE Model doesn't have that as a required step.
The Four Door Model is the least similar to the others because it doesn't follow a specific order of steps that needs to be followed. The Four Door Model allows educators to add different "doors" based on the needs of their students, whereas the ADDIE and ASSURE Models don't really allow for much to be taken out or added.

# data[].attributes.body
This step is very similar to the ADDIE model. This is where educators analyze the learners that they have. They determine what information students already know, how they learn, and what skills they are still needing.

# data[].attributes.body
Unlike the ADDIE Model, ASSURE has a step of its own to identify and state the learning objectives for students.

Step 3 - Select Strategies, Technology, Media and Materials

Step 3 - Select Strategies, Technology, Media and Materials

# data[].attributes.body
This step is similar to Develop in ADDIE. I personally like how this step emphasizes the technology, media and materials needing to be selected. Sometimes this can be an after thought in units, when it needs to be at the forefront.
I think this step especially will be important in my Instructional Unit because I will need to develop the technology, media and materials better throughout.

# data[].attributes.body
This step encompasses the actual use of all the materials that have been selected.

# data[].attributes.body
I feel that this is my favorite step in the ASSURE model. This model touches on the fact that sometimes it can be difficult to get learners to participate in lessons, however it also shows that it is an important part to the learning process.

# data[].attributes.body
In this step, we see that educators are to evaluate learning outcomes, and revise their teaching. This is an important step to all planning and units. If teachers don't revise their plans, then why even test the students?

# data[].attributes.body
Overall, I would say this model is very viable in my current organization. The reason I say this is because we currently use a model that is similar. We don't call it the ADDIE, but we do follow similar steps. We start by looking at the unit assessment that has been created by a board of teachers. We determine what needs to be changed on the assessment, but then we plan our units based around the assessment students will complete. We determine multiple pieces of formative assessments before we begin our units as well. Although teachers are free to design their lessons however they please, the assessments that students take are the same across all our 6th grade classes and schools.

I feel that this model is also extremely viable in my learning environment. Just as ADDIE was similar to what we already do, I think ASSURE is also very similar. We do take our students test results and revise what we should be doing. Although we don't revise the unit for those students, we do make notes of how it should be changed for next year. We also require learning participation in our units. I have so many lessons that if students don't respond I can't move on. Overall, I think my learning environment could truly benefit for officially adopting this model of instructional design.

This aspect of the Four Door Model is considered the meat of the model. This is where learners go to actually learn the material or to study. This is the content of the unit. Students are able to move at their own pace in this area of the model.

# data[].attributes.body
This is where learners go to socialize and work as a group. Students can utilize a lot of different technologies in this area of the model to be able to collaborate with others. This door of the model seems to support 21st century learning skills very well.

# data[].attributes.body
This is where students use games to continue their learning. The games are content related, but allow students to feel as though they aren't studying, even though they really are!

# data[].attributes.body
This door is exactly what it sounds like, it's where students go to take tests.
This is the door that I feel is the most related to the other two models that I have selected. I feel that this is similar to the ADDIE and ASSURE models because it utilizes testing students understanding of materials in formative and summative assessments.

# data[].attributes.body
Overall, I think the Four Door Model is very viable for my learning environment. This model is something that is a newer concept to myself, so I think it would take a little practice to get good at doing with my students. However, I enjoy that there are different "doors" for learning. I think the aspect that I am continuously trying to work into my course is The Playground door. I have felt that since moving to teaching ELA only it hasn't been as easy to find games for my students to play that are related to our content. This is the door that I would concentrate on most to incorporate into my classroom.
