E-learning Solutions

proctorial - exam integrity

Proctorial

a proctoring system that seeks to uphold the integrity of online exams, using a multi-faceted approach to educational assessments. It can be integrated into moodLearning-supported learning management systems (LMS). More info.

 
learning management system

E-learning Platforms and Support

online and offline tools, interactive materials for blended learning, massive open online courses (MOOCs), or e-training. moodLearning also offers support services for your LMS.

 
mL ecoach

mL eCoach

a specialized platform for running coaching programs. Using a mobile app, coaches can rate mentees and have access to their progress reports (grades, submissions, feedback) tracked across courses. More info.

 
SCORM - interactive materials

E-learning Resource Development

moodLearning specializes in the development of interactive e-learning materials, including SCORM and H5P packages, 2D animation deployable in diverse e-learning environments.


eTraining with a purpose!

E-training

on the use of e-learning platforms by teachers and staff, who should be able to effectively run online courses, monitor and evaluate trainees' performance. See also My.eTraining.PH courses and webinars.

 
antiplagiarism integrated!

Antiplagiarism Service

Bundled with supported e-learning platforms, the moodLearning antiplagiarism (mLaP) service scans documents for similarities with other materials in your own databases or repositories, or in the Internet.
