Thay vào đó, liên tục là một cách đơn giản tổ chức mô hình khác nhau theo một số ý tưởng bao quát phía sau họ. Vì vậy, nhằm mục đích nắm bắt được mức độ mà các tác giả của mô hình tuyên bố rằng phong cách dựa trên hiến pháp và tương đối cố định, hoặc | The long history of public dispute over the reliability of the LSI can be portrayed as the action of two opposing factions of supporters and detractors. But this complex picture is made more complicated still by one of the sharpest groups of critics having a change of heart as a result of research with a modified version of the 1985 version of the LSI. In a number of studies Veres Sims and their colleagues had criticised the 1985 version because the minor improvements in test-retest reliability as compared to the 1976 version were not sufficient to support Kolb s theory Sims et al. 1986 Veres Sims and Shake 1987 Sims Veres and Shake 1989 . However when they changed the instrument by randomly presenting the order of the sentence endings to eliminate a probable response bias the test-retest reliabilities increased dramatically Veres Sims and Locklear 1991 149 . As a result they now recommend that researchers should use the modified version of the LSI to study learning styles. Their stance is supported by Romero Tepper and Tetrault 1992 who likewise in order to avoid problems with scoring the LSI developed new scales which proved to have adequate levels of reliability and validity. In the technical specifications of the 1999 version of the LSI Kolb 2ooo 69 uses the data produced by Veres Sims and Locklear 1991 to claim that its reliability has been substantially improved as a result of the new randomized self-scoring format . Validity The continuing conflict over the reliability of the LSI is replicated with respect to its validity and shows little sign of the kind of resolution which the theory of experiential learning suggests is necessary for learning to take place. The latest version of the guide to the LSI Kolb 2ooo contains one general paragraph on the topic of validity. This refers the reader to the vast bibliography on the topic but does not provide any detailed statistics or arguments beyond claiming that in 1991 Hickox reviewed the literature and concluded .
