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 ## Design standards 1. **Match the level: randomization, power, analysis.** If you randomize classrooms or schools, the experiment's effective N is the number of **clusters**, not students. Power at the cluster level using the intraclass correlation (ICC) and number/size of clusters; plan the matching multilevel analysis up front (see `jedpsych-da

What does the jedpsych-study-design skill do?
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.
How do I install it?
Run `npx skills add brycewang-stanford/Awesome-Journal-Skills --skill jedpsych-study-design --agent claude-code` — it drops the skill into your project so the agent can pick it up. Swap the --agent value for codex, cursor or copilot if you use one of those.
Where does this skill come from?
From brycewang-stanford/Awesome-Journal-Skills, a repository with 909 stars. We read it straight from the repository tree rather than a submitted listing, so what you see here is what is actually published.
Is a popular skill a good skill?
Not necessarily. Stars measure attention, not adoption — a repository can trend for a week and be abandoned. That is why we show the weekly change from our own snapshots next to the total, instead of a single flattering number.
