    Qualitative and quantitative methods allow researchers to investigate, explore, and investigate the nature of the phenomenon being studied. It is important for the researcher to develop a clear understanding of the problem and design a plan to study it (Cresswell, 1998, para. 1). There are various research methods; nevertheless, it is important to determine which research method is appropriate for the study. Qualitative research focuses on human experiences while quantitative research relies on numbers, measurements and testing. However, qualitative and quantitative methods use similar approaches to conducting research and collecting data. For example, observations and interviews are approaches used in both research designs; however, the approaches are used and perceived differently. This point will be discussed later in the article. Controversy Between Qualitative and Quantitative Research Designs The two research methods, qualitative and quantitative, are different and according to Brewer (1999), the controversy between research methods has been going on for decades regarding which research design offers the most results. complete and objective data (p. 245). However, according to the reviewed literature, mixed methods appear to be an appropriate solution to this problem. Mixed methods combine qualitative and quantitative approaches and, according to Abusabha and Woelfel (2003), there are advantages to combining the two research designs: First, all data has both an objective and subjective component. Numbers can be easily assigned to all qualitative data (such as open-ended questions in surveys), and any number obtained by a quantitative study is interpreted using subjective or qualitative judgment. Secondly, by using different paper media……objective in nature, thus producing accurate data. Nevertheless, Allington and McGill-Frazon established that “reducing a complex phenomenon to a few quantifiable variables can lead to an oversimplification of the phenomenon” (p. 445). In other words, for observations to be complete, a combination of qualitative and quantitative data is necessary to explain the entire phenomenon. An advantage of pretest and posttest designs is that they can be conducted with a single group or a control group. In the proposed research topic, a pre-test and post-test were used as a group to maximize internal validity. However, in the proposed research topic, the experimental design is used to illustrate a cause and effect between two variables. The downside is that external elements pose a threat to accuracy (Leedy & Ormrod, 2010, p..230).
