Mesleki Eğitime Yönelik Tutum Ölçeği Geçerlik ve Güvenirlik Çalişmasi A Study of Reliability and Validity An Attitude Scale Towards Vocational Education

Ozet: Bu arastirmada meslek liselerinde ogrenim goren ogrencilerin mesleki egitime yonelik tutumlarini belirleyebilmek icin bir olcek gelistirilmesi amaclanmistir. Arastirmaya 2012-2013 egitim-ogretim yilinda Ankara ili Otelcilik ve Turizm Meslek, Teknik ve Endustri Meslek, Ticaret Meslek, Kiz Teknik ve Meslek Liseleri turlerinde toplam 8 okuldan 1108 ogrenci katilmistir. 35 maddeden olusan olcek ifadeleri 5'li Likert dereceleme seklindedir. Olcegin gecerligine iliskin bilgi edinmek amaciyla yapilan temel eksen faktorleme analizi sonucunda olcegin tek faktorlu bir yapiya sahip oldugu belirlenmistir. Paralel analiz ile tek boyutlulugun dogrulugu test edilmistir. Birinci faktor toplam varyansin %50,96'sini aciklamaktadir. Olcegin benzer gruplarda ayni yapiyi verip vermeyecegine iliskin olarak yapilan capraz gecerleme sonucunda tum gruplardan elde edilen yapi olusturulan alt gruplar uzerinden de elde edilmistir. Olcek maddelerine ait duzeltilmis madde-toplam korelasyon degerleri 0,57-0,81 araliginda degismektedir. Olcegin guvenirlik katsayisi Crα=0,97 bulunmus ve farkli duzeyde tutuma sahip ogrencileri ayirt edebildigi saptanmistir (p<0,001). Arastirmanin bulgulari olcegin psikometrik ozelliklerinin iyi duzeyde oldugunu gostermektedir.

In the 2012-2013 academic years, a total of 1108 students participated to the study in Ankara from 8 different vocational schools which are Hotel Management and Tourism Vocational, Technical and Industrial Vocational, Commercial Vocational, Technical and Vocational school types. The Scale consisted of 35 items to be graded by 5 point Likert type. Principal components analysis was conducted in order to understand the validity of the scale. The result of the analysis provided a single factor structure for the scale. The accuracy of unidimensionality was tested with a parallel analysis. The first factor explained 50.96% of the total variance. Cross validation analysis was performed to determine whether the scale would produce the similar results for similar groups. The analysis showed that similar result could be obtained if the scale would be applied on sub-groups. Corrected item-total correlation values of the scale items varied between 0.57-0.81. The reliability coefficient was found as Crα=0.97. It was determined that the scale could categorize students for their attitude levels (p<0,001). Findings of the research indicate that the scale has good psychometric properties.
