Plagiarism has occurred for numerous of years in different ways, but now it is a dangerous problem.
In old days, plagiarism was a grind. Needed more time and effort to go to a library, find different sources copy from that, recreate that and turn them to your own. It was taking longer time than doing a non-plagiarized work, but nowadays the web and online sources making very easy to find contents, copy and past, and it is difficult to detect. Now plagiarism is very easy fast and effortless.
For me copying someone's idea and thoughts and show as your own is like cheating with yourself. "...the consequences of plagiarism are much more serious than the consequences of turning in a paper late..."
I grew up and study in the country that had 30 years of civil war. During the war, all our education system fell apart and damage, after fall of the Taliban schools and universities reopened. In that time, everyone was thirsty for knowledge and education, but without a proper school study and resources, the only information source was the internet. Students start to get information from the internet and present as theirs own.
Literary plagiarism is common in Afghanistan and occurs unwillingly, in my opinion below are the point why it is happening
-People do not know much about plagiarism and citations.
-lack of knowledge.
-Poor time management and lack of resources.
- copying other's thoughts and writings and thinking that no one will know or catch you.
In Afghanistan most of the People didn't know about plagiarism, I remember an article "Forgiving The Unforgivable Sin Of Plagiarism." in NPR (National Public Radio www.npr.org) website.
It was about and Afghan journalist that commit plagiarism, and he mentioned that he doesn't know, it is an act of fraud to copy some words or paragraph from others writing, if you want to read the article the link is in the reference.
"If you copy text from the Internet (or from anywhere else) and put it into your story, you are plagiarizing. No excuses for this will be accepted, including "cultural differences."
But, recently due to modernization of education system, education scholarship to other universities, establishment of foreign universities, and plagiarism detection tools and easy way to find and detect the plagiarism, the culture and attitude of people has been changed, we had several books, publication, media seminars about plagiarism like a recently published book.
"Plagiarism Detection System for Afghanistan's National Languages"
During my career and studies I always respect for others thoughts, works, and ideas and whenever I used their work, I always appreciate and put a reference to them. I will be honest about my work and writings and will always cite and set reference.
I will use TurnItIn, SafeAssign to check before submission of my assignment.
As I used before safeAssign a Plagiarism detection tool and was familiar with the rating and originality percentage, TurnItIn, is also a fantastic tool easy to use and was very useful for me.
