Özet

The study is conducted with the aim of analyzing the effects of the differences between the main principles of the subject centered and stimulus centered scaling approaches on the scales and the results gathered through the scales. In this study, a Likert type scale which is entitled as "Attitude Scale towards Using Foreign Languages as Medium of Instruction" was developed. The items of the Likert Type Scale were scaled by the group of judges depending on the methods of the equal appearing intervals and successive categories. Basing on evaluation of the judge group, The Form of Successive Categories and Equal Appearing Intervals were developed. At the end of the study, The Form of Successive Categories shows similarity with the Form of Equal Appearing Intervals and the Likert Type Scale in terms of the items which are included and not included in the eventual forms. The relationship between rank of the items of the Form of Successive Categories and Likert Type Scale is low and it is not significant. The relationship between rank of the items of the Form of Successive Categories and the Form of Equal Appearing Intervals is medium and it is significant. The relationships between the rank of the subjects according to their total score which they obtained from the forms of Successive Categories, Equal Appearing Intervals and Likert Type Scale are low and they are significant. At the end of the study it is concluded that the scaling approaches have effects on the position of the items on the scale and their ranks.
