This article creates awareness on qualitative case sturdy methodology approach. The approach is meant to provide the researchers with tools for studying complex phenomena within their contexts by using a variety of data sources. This article is destined to guide novice researchers in identifying the key elements that designs and implements qualitative case sturdy research projects.
Correct application of this approach facilitates evaluation of program and development of theory and interventions in health science research. Robert Stake (1995) and Robert Yin (2003, 2006) proposed two key approaches that guide a case sturdy methodology. These approaches are based on constructive paradigm that recognizes the importance of subjective human creation of meaning. The paradigm does not reject some notion of objectivity. The paradigm maintains a joint effort between the researcher and the participant. The author reveals that the approach can be used when answering the ‘how’ and ‘when’ questions, when participant’s behavior cannot be manipulated, when there is a need to cover contextual conditions that are significant in the phenomena and when phenomena and context boundaries are not clear. To consider research questions, one must consider what the case is and what it’s not. Yin categorizes case studies as exploratory, descriptive or explanatory while Stake identifies case studies as instrumental, intrinsic or collective. According to Yin, a case sturdy can be single, holistic or a multiple. When a Researcher uses Propositions, the likely hood of placing limits on the scope of the sturdy and the feasibility of completing a project usually increase. Propositions will only fail to exist when the researcher lacks experience, knowledge or information to base propositions. The author states that a conceptual framework model is an anchor for the sturdy and can be referred during interpretation of the data. Use of database will help the researcher track and organize data sources. Pattern matching, proposition data linkage, explanation building, time series analysis and logic models are the techniques used for data analysis. The author outlines the six methods of reporting a case sturdy as; linear, chronological, suspense, theory building, un sequenced and comparative. A clearly written case sturdy, use of propositions, use of appropriate design, application of purposeful sampling strategies, proper collection and management of data and proper evaluation of data helps a case sturdy achieve trustworthiness.
I feel that this article can be of great help to a young and inexperienced researcher who hope gain tremendous insight to a case. The article is easy to understand because it brings out the points in a chronological order. Use of simple and grammatical language makes the article clear and useful to novice researchers who aspire to produce substantial findings in their researches.
