LITERATURE REVIEW DEFINED A literature review lets you gain and demonstrate skills in two areas: information seeking: the ability to scan the literature efficiently, using manual or computerized methods, to identify a set of useful articles and books critical appraisal: the ability to apply principles of analysis to identify unbiased and valid studies.

LITERATURE REVIEW DEFINED A literature review must do these things: be organized around and related directly to the thesis or research question you are developing synthesize results into a summary of what is and is not known identify areas of controversy in the literature formulate questions that need further research

QUALITY OF LITERATURE REVIEW The quality of the literature review is dependent upon The thoroughness of the writer's search The quality and  reliability of the writer's sources The ability of the writer to relate research studies to one another and to the writer's own thesis or purpose The objectivity of the writer in selecting, interpreting, organizing, and summarizing the research he or she has reviewed

PURPOSE OF LITERATURE REVIEW The purpose of a literature review is to: establish a theoretical framework for the subject area define key terms, definitions and terminology identify studies, models, case studies etc supporting the topic define / establish area of study, i.e. research topic

KEY POINTS OF A LITERATURE REVIEW Tell me what the research says (theory) Tell me how the research was carried out (methodology) Tell me what is missing, i.e. the gap that your research intends to fill

WRITING A LITERATURE REVIEW Ask yourself questions like these: What is the specific thesis, problem, or research question that my literature review helps to define? What type of literature review am I conducting? Am I looking at issues of theory? methodology? policy? quantitative research (e.g. on the effectiveness of a new procedure)? qualitative research (e.g., studies )? What is the scope of my literature review? What types of publications am I using (e.g., journals, books, government documents, popular media)? What discipline am I working in (e.g., nursing psychology, sociology, medicine)?

WRITING A LITERATURE REVIEW How good was my information seeking? Has my search been wide enough to ensure I've found all the relevant material? Has it been narrow enough to exclude irrelevant material? Is the number of sources I've used appropriate for the length of my paper? Have I critically analysed the literature I use? Do I follow through a set of concepts and questions, comparing items to each other in the ways they deal with them? Instead of just listing and summarizing items, do I assess them, discussing strengths and weaknesses? Have I cited and discussed studies contrary to my perspective? Will the reader find my literature review relevant, appropriate, and useful?

HOW CAN ONE AVOID THIS MISTAKE? MAJOR MISTAKES A literature review is a piece of discursive prose - not a list describing or summarizing one piece of literature after another. It's usually a bad sign to see every paragraph beginning with the name of a researcher HOW CAN ONE AVOID THIS MISTAKE? Organize the literature review into sections that present themes or identify trends, including relevant theory. Summarize each item briefly and follow through themes and concepts and do some critical assessment of material. Use an overall introduction and conclusion to state the scope of coverage and to formulate the question, problem, or concept the chosen material illuminates

TIPS FOR A GOOD LITERATURE REVIEW Examining existing literature review models will assist any student/researcher wishing to know how to write literature reviews that are accomplished and effective Narrow your topic - there are hundreds or even thousands of articles and books on most areas of study. The narrower your topic, the easier it will be to limit the number of sources you need to read in order to get a good survey of the material Keep your own voice - while the literature review presents others' ideas, your voice (the writer's) should remain front and center

EXERCISE Read as many as possible literature reviews written by both students and professionals
