FormulasQuestion
Feature request: new answer types "list" and/or "set"
Description of proposed feature
Add one or both of the following answer types
- set, e.g. a list of numbers (strictly numbers, no numerical expressions) where the order does not matter
- list, e.g. a sequence of numbers (strictly numbers again) where the order does matter
How can the new feature be used?
Sometimes, one might ask a question like:
- list the divisors of the number …
- find all solutions for the equation …
Currently, it is possible to have multiple answer fields, e.g. two for a quadratic equation. However, in certain cases, one does not want to "give away" the number of solutions. Currently, one would probably write something like: "if there is only one solution, enter 0 in the remaining fields". However, it would be nicer to have a field that could accept a set of solutions.
Also, currently, most people probably use a custom grading criterion to deal with the fact that students enter the two solutions of a quadratic equation in a different order. That problem would disappear with the idea of having just a set of solutions where the order does not matter.
