Development of Entrepreneurship Scale Towards Student Teachers: A validity and reliability study Öğretmen Adaylarına Yönelik Girişimcilik Ölçeğinin geliştirilmesi: Geçerlik ve güvenirlik çalışması

In recent years, the development of entrepreneurial characteristics of students has come to the fore at all educational levels. This situation began to reflect on the curriculum. Thus, to the extent that teachers have entrepreneurial characteristics may be important. Especially it can be said that science teachers who will conduct the science curriculum which is a combination of different disciplines, to what extent they must have these features. It is a matter to be examined. For this concrete measurement tools are needed. The aim of this study was to develop "Entrepreneurship Scale Toward Student Teachers". This process was firstly created to item pool. Content validity of items has been achieved by resorting to expert opinions. Application was carried out in 2013-2014 academic year. Sample consists of 730 science student teachers. To form the factor structure of the scale consists of five subscales was used the exploratory and confirmatory factor analysis. Analysis showed that factor loads is found that values between . 51 and 79, item-total-correlations is found that values between . 35 and . 68. the smallest eigenvalues has been found 3.0 and the smallest Variance ratios has been found % 41. And then five factor of the scale was confirmed by CFA. As a result of DFA was verified by considering Chi-square, RMSEA, CFI, NNFI, RMR, NFI, AGFI, GFI and SRMR fit index. the smallest Cronbach's alpha reliability coefficient is . 77 and for test-retest reliability, the lowest correlation coefficient was found to be . 66. Ozet Bu arastirmanin amaci “Ogretmen Adaylarina Yonelik Girisimcilik Olcegi (OAYGO)”ni gelistirmektir. Bu surecte ilk olarak madde havuzu olusturulmustur. Uzman goruslerine sunulan maddelerin kapsam gecerligi saglandiktan sonra on calisma ile olasi hatalar ve eksiklikler giderilmeye calisilmistir. Asil uygulama, 2013-2014 egitim ogretim yilinda olcut ornekleme yontemiyle ile secilen bes universitenin fen bilgisi ogretmenligi programinda ogrenim goren 730 ogretmen adayi ile yurutulmustur. Bes alt olcekten olusan olcegin faktor yapisini olusturmak icin acimlayici ve dogrulayici faktor analizinden (DFA) yararlanilmistir. Arastirma sonucunda; alt olceklere iliskin faktor yuk degerleri . 51 ve . 79, madde toplam korelasyonlari . 35 ve . 68 araliginda degismektedir. Alt olceklere iliskin en kucuk oz deger 3.00 olarak ve en kucuk varyans orani ise % 41 olarak bulunmustur. Bes faktorlu yapi, DFA sonucunda Ki-kare, RMSEA, CFI, NNFI, RMR, NFI, AGFI, GFI ve SRMR uyum indeksleri dikkate alinarak dogrulanmistir. Arastirmanin guvenirligi Cronbach Alpha ve test-tekrar test teknigi ile saglanmis olup, analizler sonucunda; en dusuk Cronbach Alpha guvenirlik katsayisi . 77, test-tekrar test teknigi icin ise en dusuk korelasyon katsayisi . 66 olarak bulunmustur. Bu sonuclara bagli olarak risk alma, yenilikci olma, kendine guven, firsatlari gorme ve duygusal zeka alt olceklerinden olusan OAYGO’nun gecerli ve guvenilir oldugu soylenebilir. Gelistirilen bu olcek ile ogretmen adaylarinin girisimcilik ozellikleri incelenerek, bu ozelliklerin gelistirilmesi icin eylem planlari hazirlanabilir.
