    Second Order Latent Growth Models and Measurement Equivalence
    (Turkish Education Assoc, 2011) Dural, Seda; Somer, Oya; Korkmaz, Mediha; Can, Seda; Ogretmen, Tuncay; Çetinkaya, Seda Dural
    Research problems related to individuals' behaviors and attitudes requires examining inevitable changes over time. Because learning by nature implies change, analysis of longitudinal data becomes an important topic especially in the field of education. In this article, linear changes of a particular attribute over time was studied in the framework of the second order latent growth models by using data generated from Monte Carlo simulation. All analyses were performed by using Mplus 5.1 software. Related Mplus syntaxes were introduced and the interpretation of the model parameters was discussed. Additionally, it was explained how to study measurement equivalence in these models. Analyses were performed in three steps: (1) basic latent growth model, (2) latent growth model with weak measurement equivalence, and (3) strong measurement equivalence.

    An Examination of the Factor Structure of the Turkish Version of the Online Learning Environment Survey
    (Turkish Education Assoc, 2011) Ozkok, Alev; Yurdugul, Halil; Aşkar, Petek; Özkök, Güldem Alev
    The primary aim of this study was to examine the reliability and validity of the Turkish version of the Online Learning Environment Survey (OLES) in postsecondary distance education. The OLES is a 54 item instrument for assessing social-psychological perceptions among distance education students. The second aim was to investigate empirically perception of the online learning environment in Turkish context. This paper consisted of three models explaining online learning environments in the Turkish context. Model I, based on relations of originally item-construct reported by Trinidad, Aldridge & Fraser, (2004), was analyzed with gathered data from Turkey setting by the translation, adaptation, and validation of the Online Learning Environment Survey (OLES) (Trinidad, Aldridge & Fraser, 2004) in a new Turkish-language form. In Model I, the OLES was designed to measure nine dimensions of online educational environment. The fit of the proposed multidimensional factor structure was examined with 902 post-secondary distance education students in two institutions. Model II, based on relations of emprically item-construct which were obtained with principal component analysis, was investigated with first-order confirmatory factor analysis. Model II consist of twelve subconstructs. Model III, with a higher-order construct with twelve first-order factors of OLES-TR, was perfectly represented as a general online learning environments trait rather than the OLES.
