The aim of this quantitative study is to examine high school teachers' use of specific features of interactive whiteboards (IWBs). During the 2012-2013 academic school year, 535 teachers in pilot schools from 10 provinces under the FATIH Project (Movement of Enhancing Opportunities and Improving Technology) participated. Data were collected through a three-factor usage level scale developed by the researchers and analyzed through descriptive statistics and non-parametric tests. No significant difference was found between the use of the interactive features of an IWB and sex, education level, or subject area. However, a significant difference was found between the use of interactive features and professional experience, city, computer ownership, in-field IWB training, previous IWB experience, usage duration, frequency of use, and the case of suggesting the use of IWBs to other teachers.
