1. Review of Research Designs and Techniques

2. How did we use research….
to answer problem statements
test hypothesis
formulate conclusions
We conducted experiments to determine the effects of predetermined independent variables on dependent variables.

3. Experimental Design
We aimed to determine the effects of certain factors on the life cycle of tenebrio molitor.
How do we categorize those factors?
What type of variables were the growth, length, color, activity rate etc….?

4. Experimental Research Design
How did the meal worm experiment help represent the relationship between independent and dependent variables?
What could have been done in addition to what was completed in class to increase the validity of our findings?

5. Causal Comparative Research Design
Causal comparative studies sought to seek the cause of some effect EX: Why do high school students in period 3 English class perform better then those in period 10? Q. How did the causal comparative design differ from the experimental design?

6. Descriptive Study
We tried to determine how various characteristics affected academic behavior or achievement.
The goal of this research design is to be able to describe a common characteristic within a similar population. EX: Peer tutoring works best in mathematics amongst boys between the ages of
How did we try to achieve the goal described? What instrument did we use?

7. Descriptive VS Experimental
How does the descriptive research design compare to the experimental in regards to:
Participants
Instruments
Data collection
Validity

8. Correlational
We studied relationships between variables in an effort to determine relationships between them.
EX: As level of education increases so does family income.
How did we classify those relationships?
How were the relationships quantified?
How were the relationships visually represented?

9. Practice identifying research designs….
In pairs read the article given to you and determine what research design was used…
