Mapping of Learning Activity in Sequence

Activity Structure with Selection Learner could select any activity randomly

without completing an activity. We can’t wait for a complete message after

loading an activity. Activity Structure with selection could declare

a number-to-select attribute to indicate how many sub-activities we have to complete. This imply that we have to use a loop, and the

condition follows the number-to-select attribute .
