Quest Ladder / Type groups
Type groups on a ladder
When three types cover the same ground and a learner only needs some of them.
Same idea, different question. Let the platform pick.
What a group is
Select several types on the canvas and Group selected types makes them one step with alternatives inside it. Ungroup takes it apart again, and Type group settings opens its options.
The behaviour is described in one line in the editor: each member has its own visit quota, and questions rotate at random among the members that are not yet satisfied.
Why use one
Variety
A learner retrying a step meets a genuinely different question rather than the same type again.
Coverage
Three approaches to one idea, where meeting two of them is enough.
Fairness
Two learners at the same step are not comparing identical questions.
The natural use is a concept that can be asked several ways — a rate problem as a word problem, as a graph reading and as a formula — where you want the learner to meet the idea rather than one particular framing of it.
Visit quotas
Each member carries its own quota, so a group is not simply a random pick. The rotation only draws from members that have not yet had their share, which is what stops a learner meeting the same member four times while another is never served.
The editor also previews what a specific learner would get from the group: whether a member would be skipped, reviewed or served in full, based on what they already know.
When not to group
Only group types that genuinely test the same understanding. A group whose members differ in difficulty makes the step a lottery, and a learner who drew the hard member is held back by chance rather than by knowledge.
Where the types are related but different, they belong as separate steps with a path between them. Where one is plainly harder, it belongs later in the ladder, or behind a path that only strong learners take.
