The problem spiral review solves
A unit ends, the test goes well, and six weeks later half the class has lost the skill you thought was done. This is ordinary forgetting, not laziness. The fix is to bring the skill back several times, with gaps in between, in small doses. That is the idea behind spaced repetition, and spiral review is the classroom version of it: every week a little of the old material rides along with the new.
What ClassSense does
When a student reaches Mastered on a skill (at least five answers at around 85% accuracy), ClassSense schedules a later re-check. The intervals expand: the first is a few days out, and the gaps stretch toward a month as the student keeps holding the skill.
The detail that matters is how the re-check works. It is passive. ClassSense does not send the student a surprise quiz and does not remind them. It reads the answers a student gives when they go back to a mastered skill on their own, and judges retention from those. Three outcomes are possible:
- Holding. Recent answers still clear the bar, so the skill stays mastered and the next check is pushed further out.
- Slipping. Recent answers fall short, so the skill drops back to Approaching and shows up as something to revisit.
- Not enough evidence. The student has barely touched the skill since, so the check is postponed rather than guessed at.
A teacher override stops the check for that student and skill. Your call is treated as final.
The honest consequence. If a student never returns to a mastered skill, there is nothing to judge, and the check keeps getting postponed. The re-check only works when old skills get replayed. Getting that to happen is your job.
Building the spiral yourself
Pick the skills worth keeping
Not everything needs a spiral. Choose the handful per unit that later units quietly depend on: fractions before ratios, claim and evidence before every essay.
Put old skills in front of students
Name a mastered skill on the board as the opener or as a station, and have students replay it. Their answers feed the re-check, so the work counts twice.
Add paper where useful
Generate a short Worksheet in Create Content that mixes two or three older skills with today's. Mixed sets are a gentle form of interleaving.
Read the grid on Friday
Scan the Students grid for skills that moved from Mastered back to Approaching. Those are your small-group topics for Monday.
A rough rhythm
| When | What comes back | How |
|---|---|---|
| Same week | Today's skill, once more | Short practice run, or a bell ringer |
| Next week | Last week's skill | Opener or a mixed Worksheet |
| Two to three weeks later | The skill from the unit before | One review station |
| End of term | Anything the grid shows slipped | Targeted reteach and a practice test review |
These gaps are a sensible starting point, not a law of nature. Adjust to your pacing guide and to how fast your students forget.
What it does not do
- It does not schedule review for you or put it on a student's task list.
- It does not have a due-for-review queue students can open.
- It does not generate a cumulative review automatically. You ask for the Worksheet or Assessment in Create Content.
- It cannot see what students retain on paper or in class discussion. Only the answers given in the app count.
So treat ClassSense as the memory that tells you which skills are slipping, and treat the spiral itself as a habit you keep in your planning. See also bell ringers for one low-effort place to run it.
Common questions
Does ClassSense schedule spaced review?
It schedules a re-check of skills a student has mastered, at expanding intervals. The check reads answers students give when they replay the skill. It does not send them a quiz or a reminder.
What happens if a student forgets a mastered skill?
If their recent answers fall below the bar, the skill drops back to Approaching so it shows as something to revisit.
Can I make a cumulative review from old units?
Yes, by generating a Worksheet or Assessment in Create Content on the older material. It is not automatic.
Does a teacher override affect the re-check?
Yes. Once you override a student's status on a skill, ClassSense stops re-checking that skill for that student.
