Kolb's Reflective Cycle
Kolb’s cycle in one page
| Stage | Question | What happens |
|---|---|---|
| Concrete experience | What happened? | Doing, having an experience |
| Reflective observation | Why did it happen? | Stepping back, reviewing, taking feedback |
| Abstract conceptualisation | What can I learn? | Connecting to theory; building a general idea |
| Active experimentation | How will I improve? | Trying out the new idea in the next round |
Key features
- Based on Kolb’s experiential learning cycle (1984)
- Active experimentation feeds the next concrete experience
- The model can be entered at any stage; concrete experience is the most common entry
- Designed for learning from doing, not for passive study
David Kolb’s experiential learning cycle, published in 1984, is one of the most quoted models in education. The reason is its shape. Four stages, drawn as a circle, with each stage feeding the next. The circle is simple enough that a teacher can hold the whole cycle in mind during a lesson, and rich enough that each stage actually does different work.
Where the cycle comes from
Kolb did not start with reflection on its own. He was working on how adults learn from experience. His claim is that learning happens in a cycle, and that any of the four stages can be where a learner enters. For teaching, this becomes a model for reflective practice: each lesson is a concrete experience, and the teacher learns by moving through the rest of the cycle before the next one.
In theory, a teacher can enter Kolb’s cycle at any stage. In practice, the most common entry is the concrete experience. Something happened in the classroom; the teacher reflects on it; the cycle begins.
The four stages
Kolb’s cycle has four stages, each with a question that drives it.
Stage 1: Concrete experience
This is the doing. The lesson, the incident, the conversation with a student. Kolb’s first stage is the physical act of being involved in or having hands-on experience.
The driving question is: what happened?
Concrete experience is necessary but not sufficient. A teacher who has thirty years of concrete experience and never moves to the next stage has, in Kolb’s view, one year of experience repeated thirty times.
Stage 2: Reflective observation
After the event comes the initial reflection. The teacher steps back and views the event from a more objective perspective. This stage should produce some insight into what was done and why.
Reflective observation includes taking feedback. A teacher who only reflects from her own viewpoint sees one version of the lesson. Adding student feedback, peer comments, or video review widens the picture.
The driving question is: why did it happen this way?
Stage 3: Abstract conceptualisation
The initial reflections are then explored in greater detail. The teacher interprets events and actions, looks for connections between them, and applies theoretical concepts to make sense of the pattern.
Abstract conceptualisation is where Kolb’s cycle does its hardest work. Without it, the teacher learns only “this lesson did not work.” With it, the teacher reaches a more general claim: “lessons that introduce three new terms without practice tend to produce disengagement after the third term.” The general claim transfers to other lessons.
The driving question is: what can I learn from this?
Stage 4: Active experimentation
Once the deeper understanding is in place, the teacher translates it into predictions about what is likely to happen next, or actions that should refine how similar events are handled in future. The new idea gets tested in the classroom.
Active experimentation produces the next concrete experience, which feeds the next round of reflective observation. The cycle continues.
The driving question is: how will I improve, and what will I try?
Walking through the cycle: a worked example
A teacher introduces a group activity in a B.Ed. tutorial. The activity stalls. Three students do all the talking; the rest stay quiet.
Concrete experience
The teacher notices the stall and notes the moment in her phone before the next class. The activity, the timing, who spoke, who did not.
Reflective observation
That evening, she reviews the notes. She also asks two students who stayed quiet what was happening for them. One says she did not understand the question. The other says she felt the loud students were already on a different topic. The teacher’s view of the lesson widens.
Abstract conceptualisation
She reads two short articles on group work and dialogic teaching. The pattern in her notes connects to a general idea: when a group activity opens with a complex question and no structure for who speaks, the most confident students take over. She has reached a general claim that explains the local incident and others like it.
Active experimentation
The next group activity opens with a “think on your own for two minutes” stage, followed by “share with one partner,” followed by “open discussion.” She also rephrases the opening question to be sharper. The new lesson runs. The cycle starts again.
It moves reflection from a single incident to a general claim that transfers
Abstract conceptualisation interprets the events of one lesson and connects them to theory or to a wider pattern. Without it, the teacher learns only that one lesson did not work. With it, she reaches a claim that helps her plan similar lessons better in future. The cycle without this stage produces local fixes but no real growth.
Strengths and limits of the cycle
Kolb’s model has held up well across teacher training programmes. Its strengths and limits are worth naming.
Strengths
- Simple enough to remember during the working week
- Each stage asks a different kind of question, so the model resists collapse into “just write about your day”
- The cycle structure makes follow-through visible. Teachers who only reflect once get pushed back to the next experiment
Limits
- The model says little about emotion. Other models, like Gibbs, name feelings as a stage in their own right
- The model assumes the teacher has time to move through all four stages. In practice, time pressure compresses the middle stages
- The model is individual. It does not directly address group reflection or institutional pressure
For most working teachers, Kolb’s cycle is a strong starting point. The limits become reasons to add other models on top, not to abandon Kolb.
