    Next is the Plagiarism Checker. This program lives up to it title by checking for plagiarism. Plagiarism is easiest defined as stealing or copying someone else’s work and trying to pass it off as your own. Plagiarism is a very serious offense in my opinion. This program is specifically designed to keep you from plagiarizing someone else’s work. Once you submit your paper to the Plagiarism Checker it will provide you with feedback to let you know if any portion of your paper has been plagiarized. If it comes back identified as plagiarism it is our responsibility as students to either submit a reference paper citing the original author or rewrite that portion of the paper in original words.…

    Plagiarism in an Academic Setting

    To define plagiarism, the Oxford English Dictionary states that plagiarism is "the action or practice of taking someone else 's work, idea, etc., and passing it off as one 's own; literary theft" (Last, 2007). In the academic world it has been made clear that plagiarism is a crime. Students are introduced to the issues surrounding plagiarism in their first orientation. After the first class, they are reminded and warned about plagiarizing all the way through their academic career. When a student enrolls in a college or university they are given a code of conduct and a set of rules that have to be adhered to. Additionally, all students agree to the ethical values that come with the code of conduct. If a student does not adhere to the code of conduct the rules state what the price to be paid is for each penalty. In fact, the penalty for plagiarism can be as high as being expelled from the school with a failing grade. This can ruin a student 's academic career. Since we have covered the consequences of being caught plagiarizing, what are the consequences if the student is not caught? The consequences if not caught would be that the student will not be prepared for the career that they are training for and will probably continue plagiarizing other authors throughout their career.…

    Plagiarism

    Plagiarism can be defined as using others published ideas or words and representing them as original (Bird, Sivilotti, 2008).Although plagiarism is not a new issue it has grown it the past few years due the increase use of technology. Plagiarism is one of the most challenging problems facing education (Shenton, 2010). This being due to the escalated amount of material found on the internet with ease and quickly implement into one’s own document (Shenton, 2010). In today’s age plagiarism is more accepted in between students. Most students fail to grasp the concept of properly acknowledging the information from its original source; which they also tend to believe any information found on the internet is free to use (Shenton, 2010). One can argue that there’s has been a value shift which can be questioned, due to the increase in the legitimacy of cheating and plagiarism among college students (Gross, 2011). Research recently done in 2009 states that a shift justifying cheating and plagiarism has been replacing the traditional view of cheating and plagiarism being unethical (Gross, 2011). It seems as university administration are not as aware in this shift as some researchers, although the attention is focused on how to solve this problem cheating continues to increase (Gross, 2011).In another case several students were questioned about their decision making when it comes to plagiarizing: Some said it easy to do; they are confident they won’t get caught or just out of laziness; or they view the assignment as a waste of time or even if they don’t understand the class or topic (Power, 2009). While most students had been told by a professor not to plagiarize; most students themselves did not know how to apply it (Power, 2009). Some students view plagiarizing as a minor offense (Power, 2009). Plagiarism can be explored through many avenues with more students viewing plagiarism and cheating as more acceptable maybe this…

Academic honesty is important because the whole point of academics is learning the subject. If you take material from the internet and just copy it, you’re not learning the subject, you just copy and pasted what was already available online. Next time for your paper please put information into your own words, and summarize the material with your own thoughts included to make it original. Also be sure you use proper netiquette when writing your paper, and make sure you write it in an appropriate and professional tone.…

    Turnitin is a web-based software that can detect unoriginality of student written work by comparing student submitting text with any works written before. The original purpose and main benefit of this software is that it helps reduce plagiarism. Both studies of Dahl (2007) and Walker (2010) support this fact. From Dalh's (2007) research it can be said that the use of the software creates fear of being caught which makes students more careful about plagiarism. Turnitin also encourages student to read about the correct way…
