Second Week Reflections

Through the readings for this week, I learned about critical parts of a research:
Purpose statement, research question, research hypotheses, and research objectives.
Purpose statement: is a statement that advances the overall direction. It is about one to two sentence. I can write it in quantitative or qualitative research. Its place at the end of the introduction.
Research question: are questions in quantitative or qualitative research that narrow the purpose statement to specific questions that researches seek to answer.
Research hypotheses: are statements in quantitative research in which the investigator makes a prediction about the outcome.
Research objectives: is a statement of intent used in quantitative research that specifies goals that the investigator plans to achieve in a study.
These statements are really important to make it clear for readers the key or central ideas that will be addressed in my study.
Through the readings I find myself tend more to qualitative research. I do not know exactly why, but I think the best way to investigate in problems that I faced or I will encounter in my field is the qualitative research.
Qualitative research questions are open-ended, general questions that researcher would like to answer. To design these questions, we should
Expect the change of these questions and emerge of others. Use a few questions to emphasis on learning information from participants. Ask questions that use neutral, exploratory language. Design 2 types of qualitative research questions: the central question and subquestions.
There are 5 misunderstandings about case study research:
1- Theoretical knowledge is more valuable than practical knowledge;
2- One cannot generalize from a single case; therefore, the single-case study cannot contribute to scientific development;
3- The case study is most useful for generating hypotheses, whereas other methods are more suitable for hypotheses testing and theory building;
4- The case study contains a bias toward verification;
5- It is often difficult to summarize specific case studies.
The author of this article provided good reasons to reject this misunderstanding.
The video talks about the natural occurring data and why it is important. Many researchers prefer this way of collecting data because they want to see how participants perceive or respond to a phenomena rather than looking at what they say to produce the phenomena.
