Meaning of Visibility and Access
The following figure 1 demonstrates the interplay of the date-sensitive configurations Visibility and Access . Figure 1 above has no entries. Thus Visibility and Access are not restricted. As of figure 1 below, there are different entries concerning Visibility and Access . During the period when the course element's link is visible but not accessible, there is a possibility to provide some information instead of the element's content. Please note that it makes no sense to limit the Visibility more than the Access because an invisible course element is not accessible anyway.

Figure 2 demonstrates the group-sensitive configurations of Visibility and Access . Figure 2 above has no entries. Thus all participants can see the course element's link and have access to its content, no matter if they are members of a learning group. As of figure 2 below, only the red and green group do.
