VALIDATION OF THE PORTUGUESE VERSION OF THE ‘TEACHERS PERCEPTIONS ABOUT THE PROFESSION’ QUESTIONNAIRE
Abstract
The aim of this study is to validate the Portuguese version of the questionnaire
developed by (Gilat, Kupferberg, & Sagee, 2006) and adapted by (Ezer, Gilat, & Sagee,
2010)), about the perceptions of preservice teachers in the training process experienced
and its contribution to their professional life - Teachers Perceptions about the
Profession (TPP). Two hundred and fourteen students completed the TPP questionnaire
(98 females and 116 males, aged between 21 and 41). Feasibility of scale items was
assessed by inspection of missing values (Dong & Peng, 2013). For exploration of
factor structure, a principal component analysis (PCA) with varimax rotation was
performed. Adequacy of the data for factor analysis was investigated with the KaiserMeyer-Olkin
measure of sampling adequacy (KMO) and Bartlett’s test of sphericity
(Field, 2009). Factors were extracted, using Kaiser’s criterion of retaining factors with
eigenvalues of >1, and inspection of the scree plot (Cattell, 1966). Internal consistency
reliabilities of the scale and its subscales (extracted factors) were assessed with
Cronbach’s α. The results show that TPP questionnaire is a feasible, generally reliable,
and valid instrument to assess perception of teacher education and professional identity
among pre-service teachers
