On plagiarism

Plagiarism is one of the most unpleasant things to deal with when teaching. Panos Ipeirotis wrote a blog post that stimulated some discussion, and was then removed because of legal threats. In short, he detected a fairly large amount of plagiarism in a class, but calling the students out on it created a lot of antipathy towards him, leading to a lower student evaluation, which adversely effected his own financial propects.

The later discussions suggested setting assignments that are impossible for the students to plagiarise. During my tenure teaching at the University of Otago, I saw my fair share (or more than my fair share) of plagiarism, and some of it was pretty bad.


The worst I saw was while teaching my second-year data processing course. It's not like it was difficult to detect, either: the copied portions stood out because the writing style was completely different. A few seconds with Google was usually enough to find the exact source. The easiest-detected case of plagiarism I dealt with was when a student copied from the laboratory manual - which I had written. There were so many cases of plagiarism in that course that the higher-ups changed the way in which plagiarism was dealt with: originally, all cases of plagiarism were sent to the dean of School. After a few weeks of me sending students to them, the regulation was changed to sending them to the head of department. The only penalty the students received, though, was a zero for the work that they had plagiarsied in. By the end of the year, I'd detected more plagiarism than the rest of the department put together, which raises the question: did more students plagiarise in my course, or was I just better at detecting them? If the former, was it because my course was harder? Because it was a required course that the students weren't really interested in? Or were the students really not smart enough to do the course without cheating? If the latter, why did I detect more than the other teaching staff? Was I the only one who read the assignments carefully? Did the other teaching staff not care? Or was it that the assessments in other courses were such that plagiarism was harder to commit in the first place, that is, more practically oriented?

While most of the plagiarism I dealt with was from undergrads, I have come across it reviewing papers, as well. Again, it was easy to detect: most of the paper was written very badly, apart from two or three paragraphs. Again, a few seconds work on Google was enough to find the original source. Needless to say, the paper was rejected. Since it was only a conference paper, I doubt that there were any repercussions on the authors.

As far as student plagiarism is concerned, I agree with the notion that it is better to spend time setting assessments that can't be plagiarised. The one course I taught that never had a problem with plagiarism was my fourth-year computational intelligence course. Now, that is partly likely to be because the students were highly-motivated, honours-level students, but also because of the nature of the lectures and assessment. Rather than me giving lectures twice a week, students took turns researching and presenting on a topic. There was a list of permissible topics for each week, so that the presentations followed the curriculum I had set out for the course, the students got support in researching their talk, and I went over each presentation before it was given. The practical work was entirely project-oriented, where again the students selected a project that interested them. This actually worked very well: it taught the students valuable skills and left no scope for plagiarism. I wonder, though, how well it would work for third or even second year students?

Perhaps a more important question is, why do students plagiarise? If we could answer that question, could plagiarism be eradicated? Or would there always be some students who are simply so desperate (or so unable / unwilling to do the work) that they will always plagiarise?

The problem with academic journals

George Monbiot nicely summarises the problems with academic journals as they currently stand.

• Journals get their content for free (papers submitted by authors).
• Journals get their quality control for free (reviewers volunteering their time).
• Journals get their editors for free (more volunteers).
• Journals charge thousands of dollars per year for subscriptions.

Yet, academics must publish in journals to advance their careers: university managers and funding bodies all like the nice, simple metric of counting the number of publications an academic has published in high-impact journals. And most of the high-impact journals are the ones that cost thousands per year.
 
Monbiot argues that this has the effect of shutting cutting-edge science behind extremely high paywalls, which has the effect of making science inaccessible to most of the population. When this happens, is it any surprise that hokum like the anti-vaccination movement takes hold in the population? Or that creationist baloney circulates so widely?

I think it's time for scientists, and leading scientists at that, to start submitting more to open-access journals. More importantly, it's time for managers and funding bodies to ditch the overly simplistic measures of performance that are derived from impact factors. Otherwise, things are not going to end well.

IEEE Computational Intelligence Society Multi-Lingual Social Media

The social media presences of the IEEE Computational Intelligence Society now include sites in languages other than English. This work has been carried out by the Social Media subcommittee, and so far, we have set up sites for Chinese (Simplified), French and Portuguese.

More sites are being developed and I'll blog about those when they become available. I'm also working on a report describing how the automatic translation is done, similar to this previous post on connecting social media sites. The English language sites are listed in this post. The new sites are listed below.

Teaching computational intelligence

Mengjie Zhang at Victoria University of Wellington discusses his experiences teaching computational intelligence in this article in the IEEE Computational Intelligence Magazine (access depends on your institution). What he describes seems like a fairly logical course structure. I thought I'd add my own experiences teaching computational intelligence at the University of Otago several years ago, to provide an alternative course structure.

The course I taught was a required course for third year honours students in the Department of Information Science. It was taught over one semester per year, and I taught it 2000-2003. I usually had between 15 to 30 students in it, with the number being a bit less near the end of my time teaching as the collapse in enrollments in Information Science started to bite. In addition, I usually had one or two students from other departments, usually biochemistry, as they found what I taught particularly useful.

The course was divided into five sections: data processing; rule-based and fuzzy rule-based systems; artificial neural networks; evolutionary computation; applications of computational intelligence. There were two one-hour lectures and one two-hour lab session per week.

The overall focus of the course was answering the question "What is computational intelligence and how do I use it to solve problems?".To this end, a large part of the course was focused on a small group project (two or three students per group) worth 30% of the final course grade. Students had to select a problem and data set, analyse the data, build an intelligent model to solve the problem the data was related do, and finally build a small prototype piece of software that solved the problem. The structure of the project was inspired by a survey of employers, commissioned by the Information Science department, which found that employers wanted graduates who could:

1. work in a group
2. write coherent reports
3. give effective presentations

Point 1 was addressed by making the project a small group project. Point 2 was addressed by requiring three reports during the course of the project, each worth 8% of the final grade. Finally, point 3 was addressed by requiring an in-class presentation to accompany each report, which were each worth 2% of the final grade.
The material presented in the lectures covered the relevant algorithms and techniques from both a theoretical and practical aspect, covering how the algorithms work and how they can be applied to solving problems. The theoretical aspects were reinforced by ten weekly problem sets, which were worth 2% of the final grade each. The practical aspects were reinforced by the weekly practical / laboratory sessions. These used MATLAB with the relevant toolboxes and were largely aimed at providing the students with the skills and knowledge they needed to do the project work.

The final assessment component was a 50% exam. I would have liked to have set an exam worth a bit less than that, but the University regulations at the time prevented me from doing that.

Overall, the students were very happy with the course. Apart from being well-organised, they found it interesting and useful. At least one project group even managed to publish their project in an international conference.

The lectures that I presented for this course are available here. At some point, I will make the laboratory and assessment material available as well.

While I enjoy my current research job a great deal, I do find myself missing teaching, and would like to return to it one day.
