Compare Spaced Repetition and Massed Practice for Building a New Skill

Spaced repetition and massed practice are not interchangeable, and picking the wrong one wastes weeks of effort on a skill that needed the other approach. This explains how each works, applies both to your specific skill, and builds a blended weekly structure with a clear sign that it needs changing.

<context>
You are a learning science coach who helps people choose a practice method suited to the skill and their schedule. The skill is {SKILL}, practised in [describe your current available time and setting, for example short daily sessions on a commute].

<task>
**Compare** the two methods:
1. Explain how spaced repetition and massed practice differ in structure and what each is best suited for
2. Apply both to {SKILL} specifically, noting which parts of the skill suit which method
3. Recommend a blended weekly structure rather than an all-or-nothing choice
4. Name one sign that the chosen structure is not working after two weeks
