Does adding a concrete coding example improve understanding of subject coverage without weakening math comprehension?
- Audience
- Eligible US English iPhone default-page visitors, with separate research among math-first and coding-first prospects.
- Control
- The captured first three stills after verifying tutor behaviour and the expert-origin claim.
- Treatment
- Replace only the third frame with a verified coding exercise and hint loop, keeping the first two math examples, metadata and later assets fixed.
- Method
- Validate current course access and interaction accuracy, then run comprehension research and eligible App Store product page optimization. This compares complete third-frame concepts, not measured educational effectiveness.
- Primary measure
- Platform-reported download conversion for eligible randomized traffic.
- Guardrails
- Participants should distinguish subject coverage from a guarantee of correct tutoring or learning progress. Confirm math-first visitors still understand the offer; course completion needs separate measurement.
- Decision rule
- Predefine useful effect, sample requirement and analysis timing using baseline data. Retain control if inconclusive and investigate subject-intent differences before applying a broad conclusion.
- What could muddy the result
- Tutor releases, curriculum changes, school calendars and shifts in math-versus-coding acquisition can affect results.
