Data from empirical and clinical studies over the years has shown that original four learning style types—Accommodating, Assimilating, Converging and Diverging— can be refined further into a nine style typology that better defines the unique patterns of individual learning styles and reduces the confusions introduced by borderline cases in the old 4 style typology.
With feedback from users, Kolb first began noticing a fifth “balancing” style describing users who scored at the centre of the Learning
The new KLSI (Kolb Learning Style Inventory) 4.0 introduces these nine style types by moving from a 4 pixel to 9-pixel resolution of learning style types as described below. The learning style types can be systematically arranged on a two-dimensional learning space defined by Abstract Conceptualization-Concrete Experience and Active Experimentation-Reflective Observation.
This space, including a description of the distinguishing kite shape of each style, is depicted in the figure below:
