,1 The nature and process of social research
What is social research?
• Academic research which uses the social sciences for conceptual and theoretical inspiration:
• to formulate research topics
• to interpret the findings (pag 4,5)
• This book is about the methods used to do social research.
1. Bepalen afhankelijk of onafhankelijk maar ook
2. Sociale verandering ontketenen: ingrijpen
How are research topics formulated?
• They stem from social scientists’ attitudes to prevailing social theories; (pag 5,7)
• They follow from the researcher’s existing knowledge about the current state of phenomena;
• They depend on the researcher’s orientation to theory as something to be tested in research
or to emerge from research;
• They depend on whether research is regarded as apart from the social world studied or as an
integral part of that world.
The role of ethics and politics
• Certain kinds of research – involving children or vulnerable adults, for example – require (pag6,7)
special provision with regard to ethics, limiting what can and cannot be researched.
• Research participants might need to be involved in the formulation of the research design.
• Certain research topics are more likely to be funded than others, leading to a strong
influence by sponsors on the issues actually researched.
Politiek kan meespelen in subsidiëring van onderzoek
The role of theory in research
Which comes first, theory or research? (pag 8,9)
• should we examine a problem and try to work out how it’s caused and how it might be
solved (inductive reasoning),
• or should we take a generally accepted theory of how things work and find evidence for it in
the problem we examine (deductive reasoning)?
een theorie
= een samenhangend stelsel van uitspraken waarmee empirische wetmatigheden kunnen
worden voorspeld/ verklaard.
Wat komt er eerst?
= een theorie of een onderzoek? Twee benaderingen: inductie en deductie
- Inductie: vertrekken van empirisch materiaal en gaan naar de theorie (eerst
onderzoeken, dan concluderen). vb. Je gaat mensen observeren/interviewen in de
straat. Vervolgens breng je een systematiek in de data en trek je conclusies.
- Deductie: (deducere = afleiden): vertrekken van theoretische inzichten en van hieruit
gaan naar empirisch materiaal (eerst concluderen, dan onderzoeken).
, Epistemological considerations
• What is (or should be) considered acceptable knowledge?
• Can the social world be studied ‘scientifically’?
• Is it appropriate to apply the methods of the natural sciences to social science research?
• (pag 6)
Epistemologie = kennisleer/wetenschapsfilosofie. Men vraagt zich hierbij af wanneer je
onder welke omstandigheden kennis tot wetenschappelijke kennis mag rekenen. Wanneer
beschouwen we iets als wetensch kennis?
Elements of the social research process
1. Literature review
2. Concepts and theories
3. Research questions = fasen vh onderzoek
4. Sampling
5. Data collection
6. Data analysis
7. Writing up the research
pag 8, 15
1. Literatuurstudie
"Literature review"; Wat werd er reeds geschreven over het onderwerp?
2. Concepten en theorieen
Concepten zijn de bouwstenen van de theorieën ('de ingrediënten van theorieën zeg maar')
vb. charisma, macht, ... Sterk verschillend naargelang discipline. Concepten helpen ons het
onderzoek te organiseren en duidelijk te maken aan het publiek waarover het gaat.
3. Onderzoeksvragen
Zeer scherp formuleren (zo kan je het tot in detail uitwerken). MAAR is bijzonder moeilijk!
Sommige auteurs zeggen dat je nood hebt aan onderzoeksvragen, maar evengoed aan
deelonderzoeksvragen. Maar belangrijker is, is dat de vraag kadert in de probleemstelling.
Het moet kaderen in een ruimere context.
Volgens Bryan: het gehele onderzoek wordt bepaald door de onderzoeksvragen. Werkelijk
alles draait rond de onderzoeksvraag.
Zie naar voorbeeldvragn in het handboek (Types of research questions).
- Predictieve vragen: willen iets voorspellen. Vb. de verkiezingsuitslag
- Verklarende vragen: je gaat op zoek naar oorzaken van een verschijnsel, en zo
verklaar je ze.
- Evaluatieve vragen: er wordt ergens een voorziening getroffen. (Cfr. Beschrijvende
vs verklarende statistiek)
- Verbeterende vragen
- Empowerment vragen
