### interface to symbolic math. problem generator available

Number of replies: 5Developers Forum, I thought I'd post a copy of my announcement here too.

I have developed an interface from Moodle to WeBWorK, a web-based system

for generating and grading mathematics problems (which can also be

used for physics too). The system can generate sophisticated problems

which require symbolic mathematical answers, e.g. e^x sin(4x-2) + ln(5x-2)

and it will analyze and grade such answers accurately.

The interface I have developed allows you to link to such an assignment

from within Moodle. After submitting such an assignment, you can click

on a button to return back to Moodle, and your grades from the WeBWorK

assignment will be automatically imported back into Moodle.

You can also print a hard copy of the WeBWorK assignment by clicking

a link in Moodle.

WeBWorK is open source software from the University of Rochester which

is free for noncommercial use. It is written in Perl and runs under many

varieties of Unix, including Linux and MacOS X. (It currently doesn't

run under Windows.)

You can see the Moodle interface in action by going to the following URL

https://webwork.math.ohio-state.edu/moodle/

and logging in as user doe.123 and password doe.123

You can leave your comments on the News Forum in the course.

The interface scripts and installation instructions can be found at

https://webwork.math.ohio-state.edu/moodle_scripts/

For further information and background, you can look up my posts in the

General Developers Forum. Feel free to email me if you have any questions.

### Re: interface to symbolic math. problem generator available

I've implemented the following improvements to the Moodle-WeBWorK

interface:

1) A feedback link from WeBWorK problems to a Moodle discussion

forum.

2) A variant of the interface to online WeBWorK problem sets,

which does NOT return a score back to Moodle. This would

be an interface to optional just-for-practice WeBWorK

assignments.

To see this in action, please log into

https://webwork.math.ohio-state.edu/moodle/

with login doe.123 as both username and password. The updated interface

scripts are available for download at

https://webwork.math.ohio-state.edu/moodle_scripts/

I would appreciate your reactions to this interface.

I'm trying to get into your WeBWork interface course, but I need an enrolment key. Apparently it starts with an "L"....

TIA
