Investigation of Scale Development Studies Conducted in Educational Sciences Published in Turkey by Many-Faceted Rasch Model

Abstract

The aim of this study is to investigate the scale development studies that were conducted in Turkey from 2010 to 2015 and published in the journals indexed in Social Sciences Citation Index (SSCI) by means of their verifications about scale development steps. In the study, 57 scale development articles published in between years 2010-2015 in three different journals scope of whom are educational sciences were rated according to "Scale Development Article Investigation Form" by four measurement and evaluation expert. The 19-item Scale Development Article Investigation Form was composed according to the view of the literature. The many-facet Rasch model analysis were done by using FACETS and frequencies were gathered by using SPSS programs. The analysis results of the three facets (the level of articles by means of verification of determined criteria, criteria used in investigation form, and the raters) used in the study and the rating levels of investigated criteria were gathered separately. As a result of the study it was seen that the 14th article was cover the investigated criteria mostly and the 27th article was the least cover one according to the logit scale. When the criteria used for investigation of the articles were examined, the 16th criteria was the most difficult one. On the other hand, the third criteria (There were a suitable sample for the aim of scale.) was the easiest one to meet. When the ratings of raters were investigated, it was observed that the fourth rater was the strictest one and the first rater was more lenient one. Moreover, the developed scales were given in just 27 of 57 investigated articles (47,4%) and there were no such a situation on 30 articles (52,6%). While the scoring information of developed scales for other researchers who want to use the developed scales in their future studies was given only 56,1% (f=32) of investigated articles, there were no such information for 43,9 % of investigated articles.
