In this article, I will critically analyze the strength and weakness of the use of the terms “qualitative and quantitative” in a specific area of ​​social work practice. The area of ​​choice is children's services, focusing on two research findings in the area of ​​social work performance measurement, with particular emphasis on quality of services and stability of placements for children looked after outside the family home. Both documents will be referenced under the title of first article. entitled “Performance targets and stability of placement of long-term care children away from home” Harriet Wardan and Tricia Skuse (2002) and the second article entitled “Defining quality care for children in care: the perspective of primary care workers line on standards and all that” (David Watson (2003). I chose to use the nursing framework because quantitative and qualitative studies are different research approaches and therefore need to be approached differently with respect to critique . » Frances Ryan et al (2007) However, there has been considerable debate over whether qualitative and quantitative research can be evaluated using the same criteria May & Pope (2000). such as title, theoretical framework, research design, methodology, data collection, methods, data analysis, rigor, findings, ethics, generalizability and flexibility. The title clearly indicates the purpose of the study in both articles, but for the second article, it does not say the meaning of “all of this”. According to Smith (1983), quantitative research is about explaining, predicting and developing laws that can be universally applied and qualitative research is the interpretation and understanding of what people give to their situation. The researchers have clearly stated the purpose of their studies, the aim, the objective, the objective method because they are interested in how ordinary people observe and describe their Silverman (1993). There are debates about why qualitative and quantitative can be combined because both approaches share the goal of understanding the world we live in Haase & Myers (1980). However, Reichath and Rallis (1994) argue that the two paradigms are incompatible if the qualitative paradigm assumes that there are no external referents for understanding reality. Howe (1988) suggests that researchers should move forward with what works. Quantitative research does not seek to maintain personal relationships with the people being studied or to report their perspectives. The stories include feelings, beliefs, which constitute concepts of feminist work. Feminism clings to the qualitative method because it is interested in how ordinary people observe and describe their Silverman. (1993).
