In class activity

Finding theories
Finding research articles (2개) based on the theories you found the above
Building at least 2 hypotheses based the theories
Summarize the two articles
in class -
- From the hypotheses you built
- Identifying IVs, Dvs, etc.
- Identifying level of measurement
- Identifying the nature of hypothesis
and then
what you would do (plan)
- measurement
- data gathering
- analysis
- interpret
