Qualitative research involves exploring phenomena from an inside point of view, and it provides to the researcher a complex comprehension about the subject in study ( (Rubinstein, 2010). Quantitative research involves studying the behavior of phenomena under controlled conditions that, acquiring quantitative data on the basis of accurate dimensions and generalizable findings (Johnson & Christensen, 2011). Mixed research involves the mixing of both quantitative and qualitative research paradigms. Action research involves observation and collecting of data that will help the researcher to come up solutions of solving indigenous problems (Johnson & Christensen, 2011). The strength of quantitative research is that, it is beneficial when studying a narrow number of subjects deeply as it gives a complex description of phenomena. Qualitative research assists quantitative research. Quantitative research on its own has the advantage that, it can be independently used for studying a large number of phenomena as it has some quantitative methods of collecting data that are comparatively quick (Ndunda, 2004). Being a combination of both qualitative and quantitative techniques is itself strength of the mixed research and hence it can be used for studying a large number of phenomena. Mixed research provides precise, quantitative and numerical data. The advantage of action research is that it involves practitioners who develop their own theories from their own practice gained.
Experimental research can be used in a classroom situation, specifically, in grade eight to find out whether discussion groups help in an individual’s academic performance. Here, students are organized in two groups. The first group of students is made to study individually while, the students in the second group are further sub-divided into study-groups of four. After two weeks of study, the two groups are to be given an individual self-test from which the performance of the students ...Show more
