Summary:
Learners seem to prefer optional support, where they can choose to use or not to us it.
...
| In a study, 78% of learners declared they wanted optional support. |
Yet, they rarely use it!
...
| Less than 50% of learners use support.
|
It is not only that many learners dislike compulsory support, but learners with only little pre-knowledge consider it even annoying or/and restricting.
Learners with pre-knowlegde benefit most from help.
...
Help provides an additional cognitive task.
Learners with pre-knowledge can process new information more easily and can therefore take more advantage of support.
Processing new information requires cognitive capacity. Therefore, learners with little pre-knowledge quickly reach their limits. Using support might thus lead to cognitive overload.
|
Learners with little pre-knowledge generally benefit less from help, whether it is optional or compulsory.
...
| Help may lead to cognitive overload when learners have little pre-knowledge and need their cognitive capacity to process new information.
