How and why particular research methods are used at the SLA (8)
INTRODUCTION
1.
experiments
2.
case studies
6 main methods that researchers use to conduct their studies
3.
observational studies
SLA = scientific study of society + culture can affect behaviour
4.
interviews
5.
surveys
6.
correlational studies
triangulation = incorporate 2 or more research methods
increases credibility
researcher bias - researcher's expectations subconsciously / consciously affect the findings of the study
observer bias - pp acts differently due to awareness of being observed
certain biases are present in research:
main methods used in SLA = observations + experiments
CONCLUSION
experiments - determine cause + effect relationship between 2 variables
observations - used to observe normal behaviour of pp's in their normal environments (can provide new insights + directions for research)
at SLA, main methods = experiments + observations
type of method used depends on aim of study
research methods = for collecting + analysing data
EXPERIMENTS
lab experiments = easy to replicate + eliminates irrelevant factors
example of lab experiment in SLA =
Asch 1951
attempts to control extraneous variables
Aim:
investigate conformity in an unambiguous task
quantitative research method
IV = confederates line of judgement
researchers manipulate IV + measure DV
DV = pp's line of judgement
used to determine a cause + effect relationship between 2 variables
used these results to determine % of conformity amongst pp's
experiment allowed him to develop cause + effect relationship between the 2 variables
field / natural experiments = high ecological validity
cause = group situation formed when pp's gave their answers
effect = level of conformity between individuals in the group
this relationship wouldn't have been found using other research methods eg. survey / interview
