I let students see that "real" math is about exploration and learning. I don¹t believe class should be a transcription exercise. When students see me making mistakes they don’t fear making their own. I also grade their homework on completion rather than “correctness". In exams I allow them make corrections later to improve their grade. So there is no fear about mistakes or homework or grades or anything. With fear removed the students can focus on learning rather than grades.

In Stan's <a href="http://theiblblog.blogspot.com/2014/01/destigmatizing-mistakes.html" rel="nofollow">Destigmatizing Mistakes</a> post, he writes that Ed Burger implements the following:<br /><br />1. 5% of course grades are based on the quality of student failure. In order to get an A in the class students must fail productively.<br /><br />2. Use specific activities to teach intentional mistake making as a positive strategy. An example of this strategy is to give a problem to students to work on. Their first task is to intentionally do the problem incorrectly and then share their mistake with a neighbor.<br /><br />I think these sorts of ideas can go a long way to changing the culture of the classroom.

No obvious reward for trying something interesting that doesn't work. When the teacher is faced with a stack of homework and not much time (or when the computer is grading for you!), it's easier to just check the answer and only look at the work if the answer is wrong.

I like to use sports analogies to support this idea.<br /><br />Chris, thanks for the link to <a href="http://planarity.net" rel="nofollow">planarity.net</a>.<br /><br />Joel, I love your message about "playfulness" in your address.

We all get discouraged sometimes, but if we tinker, try something, then we can start chipping away at our challenges.

These can range from the simple "Find a graph that satisfies..." to playing games that highlight graph theoretical concepts (Hashi or planarity.net) to asking students to tinker with something unclear: "What is the maximal number of cycles in a graph that has n vertices and n edges?"Christopher Hanusahttp://www.blogger.com/profile/11020601369400214573noreply@blogger.comtag:blogger.com,1999:blog-5816649486576881540.post-70581473753206147742014-04-01T08:17:56.912-07:002014-04-01T08:17:56.912-07:00I think solving this problem goes a long way to re...I think solving this problem goes a long way to really helping students understand what learning is.
