Vocab
This is a variable that the researcher studies as a possible cause of something else. This is one that the researcher directly manipulates.
What is an independent variable?
This procedure guarantees that any difference between the groups are probably quite small and, in any case, are due entirely to chance
What is random assignment?
Quasi-experimental research involves the manipulation of the independent variable without the ________ of participants to conditions or orders of conditions.
What is Random Assignment?
Randomly assigning second graders into reading intervention groups.
What is Experimental Design?
What was one of the dependent variables in this study? Hint: page 5
What is the level of improvement on the Social Skills System rating scale, Social Responsiveness Scale, and the Social Motivation and Competency Scale?
A variable that is influenced by other variables.
What is the dependent variable?
The extent to which an intervention is implemented as intended.
What is fidelity?
What kind of design is this "Does attending a selective school affect long-term outcomes? Compare those who barely passed the entrance exam (and now
attend the school) with those who failed by a tad."
What is Regression Discontinutity?
What is quasi-experimental?
What does "START" stand for?
What is Social Tools and Rules for Teens?
A group that receives either no intervention or a "neutral" intervention that should have little, if any, effect.
What is a control group?
Different participants are used in each condition of the IV
What is between- subjects?
When would you use a quasi-experimental design?
What is when the researcher is interested in IV's that cannot be randomly assigned?
A teacher splits randomly assigns half of her class to a control group and the other half to a treatment group. She then uses a standard teaching technique and a new teaching technique with each group respectively for one week and then administers a post-test of similar difficulty to all students.
What is Experimental Design?
For how many weeks were participants in the treatment group exposed to the START Program.
What is 20 weeks?
What is the treatment group?
Experimental designs offer a greater degree of control and, as a result offer greater this.
What is internal validity?
What kind of design is this: Does ABA work for children with behavioral dysregulation? Compare students’ behavioral functioning to their own performance at a different time. (Hint refer to last week's PowerPoint Slide 11)
What is Fixed Effect Regression?
You hypothesize that girls can run faster than boys. You compare their times in a 100-meter dash.
What is Quasi-experimental design?
What were the authors trying to address by allowing the control group to participate in the START group after the treatment group had completed the 20 week program? (Hint: think back to the beginning of the semester)
What is an ethical dilemma?
Whenever we compare two or more groups that are or might be different in ways in addition to the particular treatment we are studying, we have these variables in the study.
What are confounding variables?
After we can determine a change has taken place after a treatment and we have eliminated confounding variables, we have a reasonable basis on which to draw a conclusion about this kind of relationship. (Hint: opposite of correlational)
What is a cause-and-effect relationship?
Which tenet of quasi-experimental design concerns the independent variable (Hint: think about why random assignment is not attainable)
What is the independent variable is not malleable?
Do children with IEPs who receive peer tutoring perform better
on the SOL? Compare data from this group to a non-intervention group that is matched on gender, age, background, achievement, behavior, social skills, etc.
What is quasi-experimental?
What were the authors trying to address by using weekly "checklists" to track and ensure that all the content was covered?
What is fidelity of implementation?
