jedpsych-study-design
Use when designing studies for a Journal of Educational Psychology manuscript so they meet the journal's standards for educational settings — nesting (students in classes/schools), cluster-level power, measurement of learning constructs, ecological validity, and preregistration where appropriate. Strengthens the design and pre-analysis plan; it does not write code.

# Study Design (jedpsych-study-design)
The Journal of Educational Psychology expects designs that are **adequately powered for their nesting
structure**, **measure learning constructs well**, and have **ecological validity** for real educational
settings. Because JEP studies are usually students nested in classes nested in schools, the single most
consequential design decision is matching the **unit of randomization, power, and analysis** to the level
at which the treatment and mechanism operate. This skill hardens the design before data collection.
## When to trigger
- Planning a classroom/school study, field trial, or longitudinal study
- Writing a preregistration / pre-analysis plan for a prospective trial
- A reviewer questioned nesting, clustering, power, measurement, or ecological validity
- Justifying sample size at the right level
