  • 1. Formulation ofResearch Question
  • 2. Research Summer School 2
  • 3. ResearchSummerSchool3O ExplorationO DescriptionO Explanation
  • 4. ResearchSummerSchool4O To develop an initial, rough understandingof a phenomenonMethods:O literature reviewsO InterviewsO case studiesO key informants
  • 5. ResearchSummerSchool5O Precise measurement and reporting of thecharacteristics of the population orphenomenonO What is the case?O What is the nature of the relationship?O Methods: census, surveys, qualitative studies
  • 6. ResearchSummerSchool6OWhy is there a relation ?OJustifiable relation
  • 7. O Research idea provides the very basic foundationof research workO Without research idea there cannot be a researchO A ‘problem’ situation is not a ‘wrong’ situationbut we are simply problematizing the situationO Our intention is to enhance our knowledge aboutthe situationResearch Summer School 7
  • 8. Problem or Opportunity FormulationThe crucial first stage in the researchprocess—determining the problem to besolved or the opportunity to be studied and theobjectives of the researchResearch Summer School 8
  • 9. O Research problem is understanding and explainingthe problem – what I am going to study, why andhow?O Research problem sets the frame of reference forthe studyO Defining a research problem is clarifying oneselfwhat is the problem and what the research isintended to do or what are the expected outputResearch Summer School 9
  • 10. O Looking for rationalO Arriving to this problem (interest, gap, need, educational/medicaland policy change)O Collecting preliminary informationO Reviewing the literatureO Discussing with the stakeholders, other researchersResearch Summer School 10
  • 11. O We often need to write a section in our research proposal /thesisO This section can be limited just in one sentence or can be fewparagraphs long extending to more than a pageO Whatever its length be, it should define and delimit theproblemO It should also justify the problemResearch Summer School 11
  • 12. O What situations or problems tend to fascinate, challenge, or interestyou?O List as many ideas as you can as quickly as possibleO Identify which are:O Most interesting (I)O Feasible (F)O Fundable ($)O Best overall (*)O Write/Rewrite your best idea or research question?Research Summer School
  • 13. Capability: Is it feasible?O Are you fascinated by the topic?O Do you have the necessary research skills?O Can you complete the project in the time available?O Will the research still be current when you finish?O Do you have sufficient financial and other resources?O Will you be able to gain access to data?Research Summer School 13
  • 14. Appropriateness: is it worthwhile?O Will the examining institutes standards be met?O Does the topic contain issues with clear links to theory?O Are the research questions and objectives clearly stated?O Will the proposed research provide fresh insights into thetopic?O Are the findings likely to be symmetrical?O Does the research topic match your career goals?Research Summer School 14
  • 15. And - (if relevant)Does the topic relate clearly to an ideayou were given -possibly by your organisation ?Research Summer School 15
  • 16. Formulation means translating and transforming the selectedresearch problem into a scientifically answerable researchquestion.This is the aim of the study.Research Summer School 16
  • 17. O Gives specific focus to our study while staying withinthe research context as set by our research problemO Begins with a general concern that should benarrowed down to a concrete researchable issueO Defines exactly what we are going to do, how, andwhyResearch Summer School 17
  • 18. O Helps to clarify what to expect as the findings ofthe researchO Is the process of operationalizing our researchO One critical concern: are we asking the questionwe want to study?O Or, is our research question compatible with ourresearch purposeResearch Summer School 18
  • 19. Useful TechniquesRational thinking Creative thinkingSearching the literature Scanning the mediaBrainstorming Relevance TreesExploring past projects DiscussionKeeping an ideas notebookResearch Summer School 19
  • 20. O Based on literature/ideaO Includes sample description (e.g., Adult SaudiHypertensive)O Includes study design(e.g., relationship, difference betweengroups, etc.)O Includes the independent & dependent variablesO Is measurableResearch Summer School 20
  • 21. Research Summer School 21
  • 22. Research Summer School 22
  • 23. "Ask a poor question and you will get apoor research. A clear question alsohelps the investigator rapidly assesswhether the study is relevant to his orher own…practice". (Counsell, 1997)Research Summer School 23
  • 24. O Improves clarity of the problemO Facilitates subsequent steps of the research processO Helps select appropriate literature for reviewO Anticipates issues, resource needsO Improves efficiency, minimizes wasted effortsResearch Summer School 24

  • 46. O Clough and Nutbrown use what they call the Goldilocks test todecide if research questions are either too big two small too hot orjust right/O Too big need significant fundingO Too small are likely to be insufficient substanceO Too hot maybe so because sensitivities that may be aroused as a resultof doing the research . This may be because of the timing of theresearch or the many other reasons that may be upset key people whohave a role to play.O Just right are those just right for investigation at this time by thisresearch in this settingResearch Summer School 46
  • 47. O Is a formal statement of the relationship betweenvariables to be investigatedO Must contain two or more measurable variablesand must specify how the variables are relatedO Sets the framework for developing interpretationsand drawing conclusionsO Is a prediction regarding the possible outcomes ofthe study.Research Summer School 47
  • 48. O The hypothesis is the narrowest expression of theresearch question.O Summarizes the elements of the study through thedesign, sample, predictor and outcome variables.O The purpose of the hypothesis is to establish a basisfor statistical tests ( What test will be used).Research Summer School 48
  • 49. O Simple vs. ComplexO Simple: contains one predictor and one outcomeO Complex: -More than one predictor or outcome.(Not easily tested .. Can break it into simple hypothesis).O Specific vs. VagueO Specific:O Leaves no confusion about what the question is.O Clear about what is being collected.O Stated in Advance vs. After-the-FactO In Advance: provides a primary objective and a basis forinterpreting study results.Research Summer School 49
  • 50. O AlternativeO Non-directional: The difference is unknownO Directional: Existing studies/data suggest direction ofrelationship, expressed as HAO NullO Actually, hypotheses are statistically tested in their nullformO Expressed as no relationship/association exists betweenvariables, expressed as H0Research Summer School 50
  • 51. O We believe that female educators have morepositive leadership characteristicsO Our hypothesis (research or alternate, HA):women educators have positive leadershipcharacteristicsO Null hypothesis (H0): there is no associationbetween gender of the medical educator andleadership characteristicsResearch Summer School 51
  • 52. O A good hypothesis should be in a declarativesentence form specifying the relationshipbetween variables; conditional statement cannotbe a hypothesisO It must be measurable and empiricallytestable, concise and with specific meaning(clarity is obtained by means of definitions)O It should be linked with some theoretical /conceptual / analytical framework / toolsResearch Summer School 52
  • 53. Isolate and Identify the Problem, Not the SymptomsO Certain occurrences that appear to be the problemmay only be symptoms of a deeper problemO Good researchers must be creative in developingproblem or opportunity formulations byinvestigating situations in new waysResearch Summer School 53
  • 54. Determine the Unit of AnalysisO The researcher must specify whether theinvestigation will collect data aboutindividuals, households, organizations, departments, geographical areas, or objectsResearch Summer School 54
  • 55. O A written statement of the research design thatincludes a statement explaining the purpose of thestudy and a detailed, systematic outline ofprocedures associated with a particular researchmethodologyO The research proposal must communicate exactlywhat information will be obtained, where it willbe obtained, and how it will be obtainedResearch Summer School 55
  • 56. Include SMART Personal objectivesSpecific: What precisely do you hope to achieve from undertaking theresearch?Measurable: What measures will you use to determine whether youhave achieved your objectives?(Secured a career-level first job insoftware design)Achievable: Are the targets you have set for yourself achievable givenall the possible constraints?Realistic: Given all other demands upon your time, will you have thetime and energy to complete the research on time?Timely: Will you have time to accomplish all your objectives?Research Summer School 56
  • 57. O Formulate PICO questionO Write a FINER(feasible, interesting, novel, ethical, relevant)educational research questionO Translate your question into a working hypothesisResearch Summer School 57

(causal-comparative design)O How do parents feel about the school counseling program?O How can a principal improve faculty morale?Research Summer School 60
  • 61. O What is your area of interest?O Where could you look for help in decidingupon a specific research problem?O What criteria will you apply when decidingupon a specific research problem?O How could you narrow down your researchproblem?O How might your value-judgments(preconceived ideas) affect your researchendeavors?Research Summer School 61
  • 62. 1. Be clearly linked to overall project goal2. Allow the target population to be identified3. Guide the appropriate level of aggregation (e.g. class,course, curriculum, institution)4. Identify the outcome variables and key predictors ofthose variables5. Determine what type of study is needed (e.g.descriptive, relational, experimental)6.
