# Building an app for mastery learning

## Building for Mastery Learning

#### Required Measurement Components

Your app should track:

```
- Accuracy rates per concept
- Time spent per lesson (target: <15 min)
- Number of practice attempts (7-10 per concept needed)
- Success rates across different problem types
- Performance on validation assessments
```

*Note: If you are using PowerPath, the system already measures these.*

#### Progress Tracking

Implement tracking for:

* Practice attempts per concept
* Accuracy rates over time
* Time spent per lesson
* Success on validation tests
* Prerequisites completed
* Knowledge gaps identified

*Note: If you are using PowerPath, the system already measures these.*

### Curriculum Design Guidelines

#### Lesson Structure

* Design lessons to take ≤15 minutes when prerequisites are mastered
* Include 75-200 lessons per grade level
* Provide 7-10 distinct practice opportunities per concept
* Build in prerequisite checks before new concepts

#### Content Organization

* Break concepts into clear prerequisite chains
* Include multiple problem variations for each concept
* Provide validation assessments for each major concept
* Build remediation paths for struggling students

*Note: If you are using PowerPath, the system already measures these.*

### Development Best Practices

1. **Progressive Testing**

* Build in regular knowledge checks
* Implement spaced repetition
* Include varied problem types
* Require consistent performance

*Note: If you are using PowerPath, the system already measures these.*

2. **Adaptive Learning**

* Adjust difficulty based on performance
* Provide additional practice when needed
* Identify and address knowledge gaps
* Offer alternative learning paths

*Note: If you are using PowerPath, the system already measures these.*

3. **Error Handling**

* \*Detect when students are struggling
* \*Identify prerequisite gaps
* Flag unusual patterns
* Monitor for gaming behaviors
