Help for the score calculation
A course contains units, and units contains nuggets.
Units can be of 3 types: Normals, Homework and Exams.
The Normal units doesn't have dates (nor start or end). Their questions can be answered whenever and as many times as the students wants to, and the solutions are open so the students can check them up. This doesn't happen with the P2P (peer review) activities, they can be sent at anytime but only once.
On the other hand, the Homework or Exam units have beginning and ending dates. Outside of this time range the student can't attempt any activity (not even P2P submissions reviews) nor change their previous answers. The solution of the questions will only be available after the end date.
There are 3 possible activities:
- Video. The student only has to watch a video.
- Question. After watching a video, the student has to answer a few small questions asked by the teacher.
- P2P. It's an activity reviewed by peers. There is a topic, and the student has to prepare a submission, after sending it the student has to review as many partners' submissions as required.
Student evolution measurement. Progress View
A student can check his evolution in the progress view, there his activity is displayed per units.
The completeness percentage of a unit is calculated based on its nuggets and in function of the nuggets' associated student activity.
- Video. Once watched, the activity will be considered complete.
- Question. If the student has watched the video and have answered to the question, then the activity will be completed.
- P2P. Once the video is watched, the submission sent and the required partners' submissions reviewed, the nugget will be completed.
The score of the course is in the 0 to 10 range. In this calculation only the Homework and Exam units are considered. The Normal units are support content for the good development of the course, and because of that they don't contribute to the final score.
In a course, the different units may have a different weight (some are more important than others, this weights are percentages and their total value sums 100). Each unit has nuggets, and nuggets also have a weight that represent the importance of the nugget in the unit, and they are percentages too.
In the "evaluation criteria" view the student can see the weights assigned to every unit and nugget of the course.
The score of the course will then be the ponderated sum of the scores of its units, and the score of each unit (also in a 0 to 10 range) will be the ponderated sum of its nuggets. This final score can be seen at the "my transcript" view.
For each kind of nugget its score (in a 0 to 10 scale) is calculated in a different way:
- Video: If the student has watched the video, then the score is 10, else 0.
- If the student answers the questions without any mistake, then its 10.
- If he doesn't answer or he makes mistakes, then is 0.
- P2P: There are a few conditions that affect the score of these activities.
- If the student doesn't send his submission or he doesn't review the required number of partners' submissions, then the score is 0.
- If the student sends his submission, reviews at least the required number of partners' submissions, but his submission is not reviewed by the required number of partners, then the nugget will not be considered in the unit score calculation. (The weight of the nugget will be split a added to every other nugget of the same unit).
- If the student sends his submission, reviews at least the required number of partners' submissions, and his submission is reviewed by at least the minimum required number of partners, then the score of the nugget will be the mean of the partners' valorations of the nugget, in a 0 to 10 range.
Each nugget contributes to the unit score in a proportion defined by its weight as follow: 10 x weight / 100.
Note: The sooner the student send his submission for the P2P activities the better, since the probabilty of getting enough reviewers to review his work will be bigger.
