Experiential learning is most beneficial to people who have a visual, auditory, or kinesthetic learning style preference?

When you want to train or teach someone, it is not only the content that matters. The training style is also of great importance. You have to use a stile that keeps the trainees active and still interested. So you have to involve them usually by having interactive discussions and also physical movements.

So it is Kinesthetic. 

Theory of Experiential Learning

The concept of experiential learning was first explored by John Dewey and Jean Piaget, among others. It was made popular by education theorist David A. Kolb, who, along with John Fry, developed the 'experiential learning theory,' which is based on the idea that 'learning is a process whereby knowledge is created through transformation of experience' (as quoted on SimplyPsychology.org). It is based on four main elements which operate in a continuous cycle during the learning experience:

• Concrete Experience
• Reflective Observation
• Abstract Conceptualization
• Active Experimentation

The components of experiential learning assignments vary to some degree, but generally follow the following criteria:

• The project should be personally meaningful and have some significance to the student
• Students should have opportunities to reflect on and discuss their learning experience throughout the process of the assignment
• The experience should involve the student's whole person, including the senses, personality and emotions
• Previous knowledge on the subject matter should be acknowledged
