DIAMAPs--Self Scoring Kidmaps.
Doig, Brian A.
How data gathered through item response theory (IRT) analysis can be used to give immediate diagnostic information without a computer is explained. The Kidmap, developed by B. D. Wright and others (1980), provides clear information in a visual manner. Its major problem lies in the need for a computer and suitable software to construct a Kidmap. The solution lies in the proposed diagnostic map (DIAMAP). Once items have been calibrated and a raw score to logits equivalence established, items that would normally be placed in correct and incorrect columns on a Kidmap are put on either side of the central raw score scale. Items answered correctly on the "correct" side are circled, and incorrectly answered items on the "incorrect side" are circled. The raw score is marked on the central column and interpretation proceeds as for a Kidmap. An analogous version is also created for rating scale analysis; this version can give an immediate understanding of the measured trait for every respondent, based solely on raw score. This brief outline of the construction and use of DIAMAPs illustrates that good reporting methods can make IRT analysis more pertinent to the lay user. Eight figures illustrate Kidmaps and DIAMAPs. A nine-item reference list is included. (SLD)
