Kolb’s Four Stages of Learning

Last Updated: June 10th, 2019

Tool Types:


In Experiential Learning: Experience as the Source of Learning and Development (1984), Kolb defined learning as “the process whereby knowledge is created through the transformation of experience” (p. 38). This learning experience consists of four stages:

  • Concrete Experience (CE): feeling
  • Reflective Observation (RO): watching
  • Abstract Conceptualization (AC): thinking
  • Active Experimentation (AE): doing

These four stages, or steps, of learning typically move through a cycle that begins with a student having a concrete experience and ends with them actively experimenting with the knowledge they gained.

Kolb’s Four Stages of Learning

Kolb identified four different learning preferences, or learning styles, after observing the cycle of learning.  He identified learning styles as “habitual ways of responding to a learning environment.”  How students react to specific stages in the learning cycle helps identify their learning style.

Below is a grid that identifies the various types of learners and which stage of learning they lean toward. The stages of learning reflect how learners process and assimilate information:

Application to All Courses

Student learning styles are observed in a traditional classroom setting by engaging with students in classroom discussions, or observing students during lectures, group projects, presentations, or other activities. In the online environment, it is important to find ways to engage students through the entire cycle of learning and incorporate activities or prompts that will help reveal student learning styles present in your course. Remember: it is best practice to create a variety of learning experiences that reach all learning styles. Exposing students to a variety of learning experiences will also help them become a more adaptable, versatile learner.

This grid reflects examples of tools that can be found in each learning stage; however, many of these tools would be appropriate in multiple stages. Kolb recognizes that all learning stages are part of the experiential learning experience. For instance, “a classroom lecture may be an abstract experience, but it is also a concrete one, when, for example, a learner admires and imitates the lecturer. Likewise a learner may work hard to create an abstract model in order to make sense of an internship experience or experiential exercise. From the learner’s perspective, solitary reflection can be an intensely emotional concrete experience, and the action of programming a computer can be a highly abstract experience.”3
