An AVID coordinator wants to determine whether the Cornell Notes strategy causes improvements in student retention. To establish causality, the most critical requirement is:
Answer: Random assignment of students to treatment and control groups
Random assignment is essential to establish causal relationships by controlling for confounding variables.
Which term describes the extent to which research findings from an AVID study conducted in one district can be applied to other districts?
Answer: External validity
External validity refers to the generalizability of research findings to other settings, populations, or time periods.
A teacher reviews three studies on collaborative learning, all showing positive effects. What is the most rigorous next step for drawing conclusions about effectiveness?
Answer: Conduct a meta-analysis to synthesize effect sizes across studies
A meta-analysis quantitatively combines results from multiple studies to produce a more robust overall estimate of effect size.
In action research, what is the primary purpose of the 'reflect' phase?
Answer: To analyze whether the instructional change achieved its intended goal
The reflect phase involves evaluating outcomes and determining whether the action taken produced the desired change.
When an AVID study reports a Cohen's d of 0.8, this is interpreted as:
Answer: A large effect size
By convention, Cohen's d of 0.8 or above is considered a large effect size.
A researcher studying AVID tutorial effectiveness uses a sample of 12 students from one school. Which limitation does this introduce?
Answer: Low statistical power and limited generalizability
Small samples reduce statistical power and make it difficult to generalize findings to broader populations.
Which ethical principle requires that research participants understand the study's purpose and voluntarily agree to participate?
Answer: Informed consent
Informed consent ensures participants are fully aware of the research and freely choose to participate without coercion.
