Questioning is one of the most frequent strategies used by teachers during classroom interaction. Therefore, teachers employ different type(s) of questions during classroom interaction due to the uniqueness of each language classroom. This study was conducted to identify the question types asked by teachers and discover the pedagogical goals of these questions. Besides, teachers' opinions regarding question types they asked during classroom were investigated. A mixed-method research design was followed. Quantitative data was gathered through a descriptive analysis of questions types used in the classroom. Qualitative data was obtained via semi-structured interviews and stimulated recalls based on classroom observations. Three EFL teachers working at a private university preparatory school participated in this study. Their classes were observed by one of the researchers three times. The video and audio recordings were analyzed and then semi-structured interviews and stimulated recalls were carried out. The results of the study yielded that referential and display questions were the two most common question types. While referential questions were common in classroom context mode, display questions were much more common than referential questions in materials mode. The number of referential questions mostly doubled the number of display questions in classroom context mode. Even though teachers are not aware of the name of the question types, they use the questions based on the pedagogic goals of the classroom.
