The present study wants to find out the reasons for choosing the current methods/techniques for teaching grammar and it also wants to investigate whether there is a relation between teachers' thinking and their actions in the class or not. For this reason, four language teachers were selected. The subjects were selected by non-random sampling. They were chosen purposefully (case study). The data collection was done through observations and interviews. An inductive thematic analysis was used to find out the subjects' underlying concepts and themes frequently mentioned. These general themes and underlying concepts were put in some categories. Then, these categories were organized in a coherent and meaningful manner. The findings of this study revealed that the subjects (four English teachers) taught English grammar by referring to their experiences.
