1. How does "the open source way" apply to your course work?

**Developing**open source software doesn't seem to apply directly to mathematics

courses, however at U. of Rochester math department we use WeBWorK extensively for homework.

I will be teaching numerical analysis (really numerical

methods for mathematical engineering) next semester and will probably use Sage for

at least a few exercises. There are a few other professors using Sage in their research in number

theory so contributing to this open source project might spread sideways in

the math department.

2. How will you incorporate what you have learned here in your course?

What I've learned about building packages will be used in the near future to make the server component

of WeBWorK much easier to setup. This has been a barrier to using WeBWorK

and some universities and is likely to be a bigger barrier when encouraging its use

in high schools.

Much of WeBWorK has been developed with the aid of undergraduate programmers and that

will continue. This won't involve class work per se but it will be part of a few undergraduates' experience.

3. Any feedback/comments on POSSE itself you would like to add?

As one of the creators of the open source on line homework system WeBWorK

I was interested in finding how other open source communities work. This POSSE

has been very useful in that regard. I think the CommArch exercise is very useful and enlightening

and will probably try to work through it for other math open source projects -- moodle, sage,

geogebra.

Being able to meet people involved in other open source projects at this POSSE and at the

sagedays31 earlier this summer has been a very valuable experience. It's very interesting

to see the diversity in open source communities.
