3. Testing the Instrument
3.1. Participants
The instrument was tested by collecting data from 292 classroom teachers (teaching at grades 1 to 4) working in
state elementary schools located in five main districts of Ankara.
3.2. Data collection and Analysis
First of all, the researchers applied to Human Subjects Ethics Committee (HSEC) of Middle East Technical
University, and Provincial Directorate for National Education for taking permission to collect data in schools using the scale being developed. Data were collected by personally visiting the schools in May-June 2014.
In order to explore the factor structure of TAST, Exploratory Factor Analysis (EFA) was conducted. Also
Cronbach’s alpha coefficients were calculated for reliability of the whole scale and subscales. All analyses were
conducted using SPSS 21.
