Measuring what matters

Pilot study live.

We measure vocabulary retention using Cohen’s d effect size — the same methodology used in peer-reviewed education research. Our pilot study is recruiting participants now.

Design

Pre/Post Assessment

14-day vocabulary retention study with matched pre-test and post-test. Standardized measurement across all participants.

Metric

Cohen’s d Effect Size

The gold standard for educational intervention measurement. Target: d ≥ 0.5 (medium effect), aspiration: d ≥ 0.8 (large effect).
