The development, validity and reliability of TPACK-deep: A technological pedagogical content knowledge scale
Computers and Education Cilt 58 ss. 964-977
Scopus Toplam 213 atıf DOI
The purpose of this study is to develop a TPACK (technological pedagogical content knowledge) scale based on the centered component of TPACK framework in order to measure preservice teachers' TPACK. A systematic and step-by-step approach was followed for the development of the scale. The validity and reliability studies of the scale were carried out with 995 Turkish preservice teachers. The sample was split into two subsamples on random basis (n1 = 498, n2 = 497). The first sample was used for Exploratory Factor Analysis (EFA) and the second sample for Confirmatory Factor Analysis (CFA). After the EFA, the TPACK-deep scale included 33 items and had four factors. These factors were design, exertion, ethics and proficiency. The Cronbach's alpha coefficient for the whole scale was found to be.95, whereas the values of Cronbach's alpha coefficient for individual factors of the scale ranged between.85 and.92. The CFA was conducted within the scope of the validity study of the scale. In this way, this structure of the 4-factor scale was confirmed. In addition, the test-retest reliability coefficient of the scale was calculated as.80. The findings revealed that the TPACK-deep scale was a valid and reliable instrument for measuring TPACK. Consequently, various suggestions were put forward regarding the use the TPACK-deep scale for applied research and for future studies. © 2011 Published by Elsevier Ltd. All rights reserved.

Modeling preservice teachers' TPACK competencies based on ICT usage
Journal of Computer Assisted Learning Cilt 30 ss. 363-376
Scopus Havuzumuzda 67 atıf almış
The purpose of this study was to build a model that predicts the relationships between the Technological Pedagogical Content Knowledge (TPACK) competencies and information and communication technology (ICT) usages. Research data were collected from 3105 Turkish preservice teachers. The TPACK-Deep Scale, ICT usage phase survey and the ICT usage level survey were used to collect the research data. The structural regression model was conducted to test the model regarding the fact that ICT usage phases and ICT usage levels were predictors of TPACK competencies. The ICT usage phase was a statistically significant predictor of TPACK competency for all such sub-factors of the TPACK-Deep Scale as design (β=0.12; p<0.01), exertion (β=0.20; p<0.01), ethics (β=0.93; p<0.01) and proficiency (β=0.41; p<0.01). Similarly, the ICT usage level was a statistically significant predictor of TPACK competency for all such sub-dimensions of the scale as design (β=0.23; p<0.01), exertion (β=0.12; p<0.01), ethics (β=0.78; p<0.01) and proficiency (β=0.21; p<0.01). The research findings demonstrated that ICT use based on ICT usage phase and level and technology use knowledge and skills also influence overall TPACK competencies. When ICT usage phases and/or ICT usage levels are increased with the help of ICT training, it could be stated that TPACK competencies might be influenced; however, certain sub-dimensions might be influenced more, and some dimensions might be influenced less. © 2014 John Wiley & Sons Ltd.
