From the educational process efficiency point of view, the traditional form of e-learning ceases to meet the needs and the "customized" study form - personalized approach to students is more often preferred. This paper describes the design of an adaptive learning environment, as it is being developed as a part of several scientific and ESF projects. The paper focuses, in particular, on the experimental verification of the theoretically suggested characteristics of students which define their individual learning styles. We have described an initial analysis of available learning styles classifications, pointed out the results brought by pilot testing of the students and we have also described in detail the results of modified testing of university and high school students.
