What’s new in the Successive Approximation Model (SAM)?
The Successive Approximation Model (SAM) prioritizes collaboration, flexibility and iterative development. In contrast to other linear models like ADDIE, the SAM adapts to frequent changes in a learning experience thanks to its iterative phases.
The Successive Approximation Model focuses on iteration and responsiveness from the beginning and during the learning experience, instead of waiting until the end to collect and apply feedback.
Depending on the complexity of the project, we can use SAM 1 (Smaller projects) or SAM 2 (Bigger and more complex projects). In the following presentation, you have a review of the SAM 2 and its stages.
The Successive Approximation Model by Pilar GonzálezStrengths and Limitations of SAM in education K-12
The main strength of SAM is the Iterative approach because it allows to incorporate feedback in continuous updates and refinements of the learning materials. This is the best way to ensure that the learning experience is effective!
This iterative model also responds better to any change of the learning materials or needs of the learners. However, the continuous need of refinement and collaboration is resource-intensive and requires a deep knowledge of SAM for the instructional designers and the rest of stakeholders.
The SAM requires continuous updates based on feedback received from groups of learners before the launching and final phase. In Education, we do not have the time or the group of learners to test the materials previously because we need a final version that we can present to our learners from the first day of school.
On the other hand, I do recommend this model for companies that design learning materials to be open to receive feedback and make updates based on our students’ surveys.
Our students are already using many e-learning materials in the classroom, mostly during and after the pandemic. However, the learner’s or teacher’s feedback is not solicited after the school district has purchased the learning materials. I would encourage and recommend to include student friendly surveys to gather their feedback, in addition to the teacher’s one.
Implications of SAM for Instructional Design
In the previous models, the collaboration with stakeholders is required in one specific stage. However in the SAM the collaboration with stakeholders is present in all of the stages. That continuous feedback is beneficial for the project because the Instructional Designer can adjust different elements at the moment to refine and improve the whole learning experience.
The SAM implies a detailed development of the Instructional materials, creating different versions that are refined with continuous feedback. The level of excellence and performance is higher than in previous models if you review the requirements in the stages.
