Pebble-in-the-Pond Model
Pebble-in-the-Pond was developed by M. David Merrill, an instructional design researcher and academic who came up with the model as a major component of his Theory on the First Principles of Instruction.
The Pebble model’s focus is on the instructional design phase of the whole instructional development process and assumes that some front-end analysis has already determined that there is a problem that can be solved by instruction rather than by some other means. It is a design rather than a development model. This means production, implementation, and summative evaluation are not considered in this model. (Reiser & Dempsey, 2018).
- First ripple – Prototype
- Second ripple – Progression of Problem instances; with demonstrations or applications for each problem in the progression
- Third ripple – Component skills required to solve this class of problems
- Fourth ripple – Enhancing instructional strategies through learner guidance and peer interaction
- Fifth ripple – Finalization of the functional prototype including the final design
- Sixth ripple – Contains data collection, formative evaluation, and prototype revision

Reflection
The pebble-in-the-pond model of instructional design is an effective way to create meaningful learning experiences for students. This model emphasizes the importance of creating a ripple effect of learning, where each new concept builds on the previous one. By using this model, educators can ensure that students are able to build a strong foundation of knowledge and skills that can be applied to future learning. This model can create a learning environment that is both engaging and effective, and students can build on their knowledge and skills as they progress through the course, ensuring that each new concept is connected to the previous one. This can allow students to develop a deeper understanding of the material, and to apply their knowledge in meaningful ways. By using this model, educators can ensure that students are able to build a strong foundation of knowledge and skills that can be applied to future learning.
