The author of this research tries to critically discuss the disadvantages and advantages of qualitative and quantitative approaches and the methods used in language testing and in assessment research. The study starts by introducing the background of the procedures and research methods. The brief description of the assessment is provided. The cons and pros of using both methods are discussed. Finally, the ethical considerations are also noted.

The author did not discuss how qualitative research approaches may be developed for better usage in the future or are there any plans for the same. He has noted that it produces a better and detailed description of the participants and it also interprets the meaning of their respective actions. The author has not elaborated on the accuracy of both quantitative and qualitative research methods.

From the research, quantitative appears to be more appropriate compared to qualitative since it deals with quantification while collecting data and therefore has a higher likelihood of proper representation and better results.

• DISCUSSION:

DESIGNING QUANTITATIVE RESEARCH

The threat to internal validity in quantitative research are the factors which affect the relative truth about the inferences regards cause-effect, like maturation, instrumentation, and selection. External validity in quantitative analysis is the factors which influence the extent to which research findings are generalized to the same population which the sample is taken. The best strategy to mitigate internal quantitative research threats is by improving how you implement your methodology and avoiding poorly designed research techniques and tools (Babbie, 2017).

On mitigation of external quantitative research threats, is by ensuring the sample design and procedures are a representative of the various characteristics of the study population so that the findings are a representative of them. The ethical issues are vital in matters relating to an unbiased and fair selection of sources and in the analysis (Babbie, 2017). A research topic to be amenable to scientific study using a quantitative approach is that a method which adopts a more significant number of the subjects and various survey methods which can be applied to address the existing problems (Babbie, 2017).
