This is just a short sketch. The idea is like follows: A student is working within a learning environment such as ActiveMath. Beside an opened book/course the student has also activated the learning diary which is displayed somehow. While the student is writing an entry in his diary, the diary itself asks ActiveMath in the background for the current context. The context information comprises the book’s id and all items of the current page. One could simply assume that while the student is writing the entry he is reflecting on the learning items of the current page.
