| | 164 | Bolt offers a ''memory refresh'' system that periodically repeats exercises |
| | 165 | and, if necessary, lessons. |
| | 166 | Memory research suggests that this is necessary for students to shift |
| | 167 | learning to long-term memory. |
| | 168 | This mechanism works as follows: |
| | 169 | |
| | 170 | * A sequence of ''inter-refresh intervals'' is defined. For example, (7, 28) means that an exercise should be repeated 7 days after it is first taken, and then every 28 days thereafter. |
| | 171 | * Bolt provides a function that returns the set of items, for a given student, for which refresh is due. Your course can use this function to implement a "Review now" button on web pages. |
| | 172 | * Bolt provides a "review mode" in which the student is presented with exercises due for review. |
