 Understanding Research Methods

week 1 Assignment :


Please write your research question. Please ensure your submission is less than 100 words.

Nanotechnology has become one of the hottest area in research and development worldwide and also attracted media and investment community.Preparing Carbon Nanodots (CND’s) by facile and low cost processes have received considerable research interest due to its various applications. In this work we report green approach to prepare CND’s through hydrothermal treatment using grass as a green source as it is cheap and abundantly available in nature. Present study is developed to find the role of CND’s for the detection of toxic metals as these metals are harmful for environment and mankind so as to develop cheap and effective method for detection of metals by CND’s which is prepared by grass which is easily available. Is that possible to use natural material to work on pollution sites and detect heavy metals from lakes and oceans? That's what our work and research is all about. By introducing synthesis and undergoing characterization, prepared CND’s be used in toxic metal detection. Their photoluminating performance will be observed after being kept for an extended period of time. Can Further use of CND’s be used for the detection of heavy metals such as Mercury, Cadmium and Iron which are harmful to mankind.

week 2 Assignment :

Summarise your understanding of the main points of Booth, Papaioannou and Sutton's or Hart's or Kiteley and Stogdon's chapter in no more than 200 words.

-The chapter starts with an elaborate definition of Literature. 

-Then the Author gives us a brief insight about the nature of knowledge and Evidence in Social Care Practices. 

-We are introduced to Grey Literature, which means the various types of documents produced by governments, academic institutions, businesses and industries. These aren't controlled by commercial publishers and aren't published through conventional routes often making them difficult to find and access. Along with this a list of pros and cons have also been mentioned.

 -The Author covers the types (Narrative and Systematic) while defining the Literature Review and views it in two contexts

 1) Literature Reviews as preparation for empirical research 

2) Literature Reviews as stand-alone pieces of work Different methods of Literature Review have been mentioned such as Search Methods, Data Extraction Methods, Critical Appraisal methods etc. The process of synthesis in relation to literature reviews has been described and key synthesis methods identified by Rutter et al have been mentioned. Last but not the least the author gives us an overview of the length and structure that should be maintained with respect to the type of literature we're reviewing.

week 3 Assignment :


In no more than 400 words, please respond to Chapter 1 from John W. Creswell, Research Design Qualitative, Quantitative. and Mixed Methods Approaches Second Edition (Sage, 2003)

Research approach, design and methods are crucial part of planning. Research approach refers to the holistic processes and procedures commencing from the broader discussion of philosophical theories and assumptions to the detailed execution of research activities such as data collection, analysis and interpretation. There are primarily three research approaches namely qualitative, quantitative and mixed method. Qualitative method mainly encompasses use of data based on interviews, open ended questions that are not numeric in nature. On the other hand, quantitative method employs numerical data such as surveys with close ended questions. Mixed method approach uses a mix of both numbers and qualitative data. It must be noted that qualitative and quantitative approaches are at the two ends of the continuum and mixed method based in the centre. Selection of research approach can be based on the philosophical world view and the research question. There are generally four types of worldview namely post-positivist, constructivist, transformative and pragmatic. These world views form an essential basis for the selection of research designs and methods. For instance, post-positivist world view is based on cause and effect, which leads to quantitative research design particularly experimental research. While constructivist world view is based on subjective meaning of individual experiences. It therefore, leads to the selection of qualitative research design such as narrative inquiry. The book therefore provides some of the different types of studies under different research design. The details are as given below: 1. Quantitative research design: a. Survey research b. Experimental research 2. Qualitative research design a. Narrative research b. Phenomenological research c. Grounded theory d. Ethnography e. Case study 3. Mixed method design a. Convergent mixed method b. Explanatory sequential mixed method c. Exploratory sequential mixed method While broadly the above are some of the key elements of research approach, the research designs are also determined by other factors some of which are: Research problems or questions - it is mainly influenced by the type of research problems and approaches including gaps in the literature; Researchers’ own personal training and experiences - for instance, an individual who is well trained in statistical analysis will lean towards quantitative research design; and choices of audiences and their acceptance of research design and research question.
