Apart from above mentioned critics there are also discussions about learning style researches and
their floes in validity and reliability (Coffield et al. 28-30; Bricheno, and Younger 30). For
example, Dunns‟ claims for validity and reliability are not supported by independent evaluation.
This unfavourable fact was, probably unwillingly, confirmed by Rita Dunn herself as she boldly
