wayfinding is difficult when there is so much net to choose from.

I have invited all students or newbies to blog so they can find relevant items that they enjoy reading or seeing. the hub is the classroom VLE virtual learning environment " moodle ". Without a hub or somewhere to look for what have we done in terms of themes for the module work many would loose their way in the various networks. Overload of information for the course is created by their own blogs and soon as the students want to just read relevant stuff to get a piece of work done the blogs posts may drop off. The value of them at the start of projects is to share in a space that can hold and remember their finds . The context of the course such as finding a way to claim council tax back or finding how to get e services is vital at the beginning to settle students.So blogs will change both in content and number of posts as the course goes on. This means it is against good course design to expect a post a week on a topic chosen by the teacher. Or maybe you disagree?
Darken split the tasks set for way finding into 3;

Wayfinding Tasks
Wayfinding tasks are classified into three primary categories:
1. Naïve search: Any searching task in which the navigator has no a priori knowledge of the whereabouts of the target in question. A naïve search implies that an exhaustive search is to be performed.

2. Primed search: Any searching task in which the navigator knows the location of the target. The search is non- exhaustive.
3. Exploration: Any wayfinding task in which there is no target.
