And most of the students commit such mistakes. The core reason behind this is unclear concepts and understanding which lays the base. Hence strong concept base is very much required to escape from these blunders.Zack Humeshttp://www.thesisclinic.co.uk/statistical-help-using-spss.phpnoreply@blogger.comtag:blogger.com,1999:blog-4242439961617529545.post-15882227139517084262016-09-21T21:36:19.891+01:002016-09-21T21:36:19.891+01:00I'm guessing this was a reply to my comment ab...I'm guessing this was a reply to my comment above.<br /><br />Sorry, I forgot to mention that I was working in the ring R[ϵ]/ϵ^2 so that Newton and Leibniz's ad hoc approach to calculus works pretty much as-is. I find this far more accessible to students than Cauchy's ϵ-δ definition which, if I were to use the language of limits, I would of course spend the required five weeks to Loopspacehttp://loopspace.mathforge.orgnoreply@blogger.comtag:blogger.com,1999:blog-4242439961617529545.post-37990296287825862642016-09-20T15:22:25.492+01:002016-09-20T15:22:25.492+01:00AAARRRRRGGHHH!!!!

I think that Maths has an image problem (and I will admit that I may be hyper aware of it) and part of it is that Maths is all about "right answers". I really want my students to see the messy side of maths, and part of that is being able to make mistakes and tidy up afterwards.Loopspacehttp://loopspace.mathforge.orgnoreply@blogger.comtag:blogger.com,1999:blog-4242439961617529545.post-47236164499636610222016-09-19T21:16:00.049+01:002016-09-19T21:16:00.049+01:00Thanks for your comment.

As I say in the post, it's a jokey way of trying to get students to stop and think when they make one of these common mistakes. I've found this kind of thing (eg the kitten killing joke) effective in the past for engaging students in conversation about misconceptions.
