| 32 | | Bolt's deeper goal is to let you create better courses: |
| 33 | | to find out exactly how effective each lesson is, |
| 34 | | to make statistically valid comparisons of alternative lessons, |
| 35 | | and to make "adaptive" courses in which different lessons are used |
| 36 | | for different groups of students. |
