  The growth of Internet has led to new approaches for distance education. The
main mechanisms involved in this process are distance learning and distance
evaluation. Distance learning have multiple forms, from browsing and finding
information when needed or collecting information onto ready-to-use packages,
to interactive content where the learner is able to affect and control the
content in some way. From the teacher's point of view, evaluation of learning
aims to determine whether the students have achieved the goals set for a
particular topic or course. Typically this is tested somehow and based on the
test results, evaluation is performed. This kind of method is always restricted
to the test, however. Many times the students may actually learn something
completely different from those that are tested. Furthermore, testing does not
necessarily take the students' individual needs into account. However, when
properly designed, the testing method is a practical and even fairly reliable
way of evaluating learning.
