Hi, I'm happy I read your forum message. I think we might study in the same online college:) What a great explanation of the reflective cycles.
Both of the cycles are used in setting to evaluate and change the performed activities. I like Kolb's reflective observation where we think about how well activity went, what was a success and what could be changed. It helps to plan the future activities better. Sometimes it is enough to change the resources. Sometimes we might think of changing our own approach. It also can lead us to a conclusion that we might need a further professional development in some areas.
The Gibbs reflective cycle reminds me more ABC forms. His theory concentrates more on the reasons for the children's behaviour. The teachers have an opportunity to reflect how they handled the situation.
