Interview Guide
A general interview guide was used with semi-structured interview questions in an emergent design format developed to gain information from the interviewee. The questions for the interview 54 guide were designed to be interpretive and were drawn from a review of the literature. A Responsive Interviewing protocol was developed with follow- up questions and probes. This allowed the researcher to ask additional questions to explore the particular themes, concepts, and ideas introduced in the initial interview. Probes were also part of the responsive interviewing protocol I used as a technique to keep the conversation going in order to complete an idea, fill in a missing piece, or request clarification (Rubin & Rubin, 2005). Terms of Validity and Reliability Credibility and authenticity are major components of validity in qualitative research. Qualitative validity means that the researcher checks for the accuracy of the findings by employing certain procedures, while qualitative reliability indicates that the researcher’s approach is consistent. In regard to validity with qualitative research, Stake (1995) created a list of ‘Things to Assist in the Validation of Naturalistic Generalizations’ (p. 87). 1. Include accounts of matters the readers are already familiar 55 with so they can gauge the accuracy, completeness, and bias of reports of other matters; 2. provide adequate raw data prior to interpretation so that the readers can consider their own alternative interpretations. 3. describe the methods of case research used in ordinary language including how the triangulation was carried out. 4. make available information about the researcher and other sources of input (p. 87). Stake believes it is the responsibility of the researcher to assist readers to arrive at high quality understandings of the findings. The researcher’s analysis and interpretations have to parallel that of the readers’. Triangulating different data sources of information by examining evidence from the sources and using it to build a coherent justification for themes adds validity to the study (Patton, 2002; Creswell, 2009; Yin, 2009; Stake, 2010) and also serves as support for Stake’s ‘high quality of understandings’ (p. 88) that he asserts a researcher must obtain. I have used multiple sources of evidence to collect my data, keeping careful notes and using a credible subject who is considered 56 a model teacher in the district. My interpretations are well grounded in the data I collected employing triangulation in my design consideration. I was persistent in my observations in order to generate rich data for analysis and interpretation. Download 1.49 Mb. Do'stlaringiz bilan baham: |
