Evaluation process should include a great variety of evidences that go beyond the traditional final examination based on paper and pencil.
Face-to-face contextFace-to-face context
Professors use more than just formal mechanisms to evaluate students. body language participation
Quality of questions proposed by students are good indicators of learning

What normally occurs it is the use of formal mechanisms only
Why ?Why ?
It occurs not only because of the lack It occurs not only because of the lack of accessible mechanisms that can of accessible mechanisms that can assist instructors on this task, but also, assist instructors on this task, but also, because many professors prefer to because many professors prefer to work with more traditional methods of work with more traditional methods of evaluation.evaluation.

Tool of consensusTool of consensus
It allows on time creation of enquete proposing instigating questions, as well as the collection and tabulation of responses;
The tool has the capability to keep track of each student's level of contribution to the discussion as well as enquete responses.
Tracking toolTracking tool The register of learning activities
(accessed page with dates and time) is important because it allows the professor to know the progress of students trough the course;
The collected information will show that type of access the student has made (visited units, tools used, etc), as well as the time spent on it.
Voting toolVoting tool
Aimed to provide conditions for a fast feedback for the instructor on specific subjects.
Self-evaluation toolSelf-evaluation tool
Allows the dynamic building of enquetes for self-evaluation by professor and by students.

ConclusionsConclusions Formative evaluation plays an important
role to get distance students motivated because they feel a sense of not being lost in space
Just the opposite, they feel that being closely monitored and having their opinions being asked often is more like having a personal tutor that pay attention on way they do and what they say.
ConclusionsConclusions
This kind of attention provided by the system helps to minimize solitude that sometimes is referred as main desisting factor from students in distance education programs
