UNED, has started the UNED-COMA (Curso Online Masivo Abierto; in English, UNEDMOOC) project for
managing massive courses with multimedia videos and social interaction tools (like forums).
In particular, UNED-COMA is an open initiative created in the 2012 year.
The OpenMOOC platform is employed for this purpose.
The main objective of this initiative has been the exploration of the rich experience with the distance educational
methodology employed at UNED.
Not oriented towards learning analytics.
Nowadays this platform has been replaced by OpenEDX
OpenMooc has three databases:
Database PostgreSQL related towards the structure of the courses and users profile data.
Database MySQL, a database for each forum:
OpenMOOC is based on AskBoot for handling forums (https://askbot.com/).
Database NoSQL MongoDB, oriented towards activities interactions this database was not available.
Youtube analytics from 2015:
Fundación CSEV (https://www.youtube.com/user/FundacionCSEV).

POSTGRESQL: STRUCTURAL CONCEPT
Course Users Groups
POOR STUDENT PROFILE INFORMATION
Detect the sex of the students using an
automated function that uses public name
lists such as Spanish Government Statistics
popular names lists and the usernames.
Not always is possible.
Almost a 10% is not classified.
• Evaluation related videos have
a high number of views and
• Rest of the videos have a
lower number of views.
Hypothesis 1: shorter videos are better for the students’ outcomes.
Hypothesis 2: courses with fewer videos are more successful that those ones with a great number of videos.
Number of videos per course.
Mean duration of videos per course.
Mean amount of visits per video in the course.
Mean amount of likes per video in the course.
Three types: coments,

Content_type Type of activities: voting,
EXAMPLE OF FORUM BEHAVIOUR
Statistics and histogram:
Only 2240 students participate in
the forum (reading or writing):

Number of activities.
Number of questions.
Number of answers.
Number of comments.
Percentage of the number of students.

A set of hypothesis have also been proposed and discussed from the detected candidate variables (indicators)
This indicators are about students’ behavior in MOOCs given both from the point of view of videos and debate
A clear need to improve the platform with further learning analytics.
