How Plagiarism is Detected in Moodle

All of the content that is submitted to Moodle can be scanned for plagiarism. The submissions are scanned easily and automatically.

The Turnitin plugin can be used to detect students’ work for plagiarism. It is a commercial plagiarism detection system that you have to pay for. Many instructors enable Turnitin to detect plagiarism as it is very effective.

Turnitin uses an Overall Similarity Index to instantly determine the amount of the student’s paper that matches outside sources. The Originality Report will then help educators investigate suspicious passages in the student’s work. Turnitin is efficient in detecting plagiarism to test the authenticity of a student’s work.


PlagScan also allows educators to scan a student’s work for plagiarism automatically. Assignments can easily be checked without using an external interface. Moodle instructors, teachers, and students are all offered a PlagScan account to guarantee that only users who are supposed to access a document are allowed to do so.

The Video Editing Software I Use

I do a lot of video editing for my online websites, blogs and elearning content and I am always looking for software that is easy to use with powerful features at a cheap price. I am not against using open source software or free software but when my income relies on it paid software is the only way to go as you have guaranteed support options with someone available to get me unstuck.

I have trialled many different tools but for speed of editing and powerful features to automate a lot of what I am doing I keep coming back to Wondershare Filmora. The tools it has around vlogging are quite cool as well and for under $50 USD a year or around $4 USD a month it pays for itself just in the time saving.

Click here to give the trial a go and see if it works for you as well.

PRO TIP: The latest version of Filmora has some great speed enhancements that make processing the completed video way shorter than previous versions so if you already have it maybe think of upgrading if your time is important to you.
