Turkish adaptation study of instructional materials motivation survey (IMMS) [Öğretim materyali’ne İlişkin motivasyon ölçeği (ÖMMÖ) Türkçe uyarlama çalışması]

Although many studies focus on academic achievement in educational sciences, variables which affect academic achievement should also be examined. Motivation is the prominent variable that enhances academic achievement. Motivation can be measured in various ways and has different sources as well. It is important to evaluate materials, which are one of the essential elements of teaching, in this respect. Thus, the aim of this study is to develop an instrument to assess motivation regarding teaching materials. For this purpose, a 36-item scale consisting of four constructs developed by Keller based on ARCS Motivation Model has been adapted into Turkish. Since some statements and sample of the assessment instrument have been changed, all development steps of the scale were re-enacted from the beginning. Initially, first and second edition of the assessment instrument have been analyzed with explanatory factor analysis; then, the scale obtained has been tested with confirmatory factor analysis. A sample of 1361 middle school students has participated in the study. Out of this sample, the data obtained from 469 have been used for the first edition; the data of 568 participants have been used for explanatory analysis whereas the data obtained from 295 participants have been used for confirmatory factor analysis. Negative statements in the original version of the scale have been transformed into positive ones in order to help the participants, who could not code these negative statements. Three positive statements, which have been found as vague in terms of meaning, have been excluded from the scale to obtain a 33-item assessment instrument with four subscales. For this instrument, the internal reliability coefficient has been found.93 in the factor analysis. As for the values of confirmatory factor analysis, they were found at an acceptable limit value. In conclusion, the results of the study have put forward that this assessment instrument could be used in order to determine middle school students’ motivation levels regarding teaching materials. © 2016, Ankara University.
