With the permission of onlinecolleges, I will be running a series of their infographics related to online learning.

Today’s is on how Google (and presumably other search engines) impact on how we remember things – both the pros and cons.

Infographic on cheating in online learning

onlinecollege.org has produced this interesting infographic: Do Online Students Cheat More Often?, comparing cheating online with cheating in class.

My interpretation of their results is slightly different from online college.org. They report a higher proportion of online students admitting to cheating, but the difference is just 0.6% (31.7% to 31.1%) on a sample of 635 students, which I would guess is pretty much a no significant difference statistically, more due to chance, or at best not a meaningful difference.

More interesting was that classroom students were almost twice as likely to be caught – but again the numbers actually caught are low (less than 5%).

There is a useful set of tips on how to prevent cheating in online courses. The only one I would add is the use of an Internet plagiarism detector tool such as turnitin.com. Just the threat of using it I found stopped a lot of cutting and pasting from the Internet without proper referencing, although that has subsequently been somewhat offset by their own software showing students how to avoid being caught (Writecheck). (Sorry, ‘inadvertently’ copying from the Internet – yeah, right). This enables students to change the copying just enough not to get caught – pretty much what academics do at times, as well.

Overall, though, a very useful infographic from onlinecollege.org – and thanks to them for permission to reproduce it (phew – I was nearly guilty myself.)

Daily Infographics (2012) The World of Mobile Phones, January 20

I’m posting this infographic, because the Canadian government is looking at changing the rules about foreign ownership of telecommunications companies.

It can be seen that Canada has a relatively low penetration of mobile phones, because it has some of the highest charges. There are three main companies in Canada, and opening up the market to foreign competition and tweaking the rules to give smaller companies connections to the main networks at reasonable cost is considered to be the best way to get the rates down.

One reason some countries though have high mobile phone ownership is because there is no reliable terrestrial phone network. Mobile is the only form of access in some countries. Nevertheless, there is no such reason to explain why Canada has less mobile phones per person than say Chile or Germany.

Just as important though is the bandwidth – with increasing demands for video and graphics, the availability of broadband access is as important as the number of phones per person.

I’d like to see a similar map for tablet ownership.

I’ve shown only a portion of the whole graphic. The full graphic (and many other fascinating graphics) can be found at Daily Infographics
