As a qualitative data collection tool, interview enables the researcher to gather data that observation and questionnaire techniques cannot unravel and to examine the participants’ feelings, opinions, perceptions, and attitudes. Observation means reviewing naturally- emerging signs of an event/phenomenon to comprehensively understand that event/ phenomenon. Diary can be described as a source of data where the researcher writes down her/his comments, feelings, and opinions about events that s/he observes and hears and where s/he can add her/his reflections about her/his experience. Documents refer to any kind of written, audio, and/or visual materials that bear information about the focal events or phenomena in a given research. Artifacts are another source of help qualitative researchers can use to answer the research questions. They can also be described as physical evidence for qualitative research. Artifacts refer to object(s) located within the focal context, and somehow, they appeal to the researcher’s interest.
