There are some minor navigation problems.

When I put in the student_dashboard code:
[cp_pages page="student_dashboard"]

The student will see an list of the course there are in.
But there are some minor navigation problems.

There are to links that are going to the same place? That doesn't give any meaning?
See: http://screencast.com/t/0YO9RGts

The botten "Course details" should go to the course so that button should be like in Course view. http://screencast.com/t/wdwpgRrb0
Go to course
fx:
http://siteurl.com/course/coursename/modules/

Offen you are clicking so many times. When you are enrolled in a course, why alway.

An other thing is the style the student dashboard with thumbnails, why is the thumbnails not there?
