Overall implementation took place in a Turkish Language Learning Research Center in a state university in Turkey. We have collected the data via the Interactive Whiteboard Survey for University Students, achievement tests as well as semi-structured interviews with students to support quantitative data after the implementation T-tests and descriptive statistics were used for the analysis of the survey and content analysis for the interview data by using, QSR Nvivo 8.0, a qualitative data analysis tool.
