![]() The students quickly realized that there was incentive to make their edits early. I ended up not allowing this type of minor edit in the latter part of the semester because there were so many lingering non-corrected errors. I was surprised (although in retrospect it isn’t too surprising) to discover that many students would rather type the solution to a non-assigned problem for their minor edit than to read through an existing solution in search of an error. Of course, wikis have excellent version histories, so I could always go back and see who edited what, when. Each student had their own page on the wiki where they kept a log of which major and minor edits they made, and the dates they made them. Thus I only kept track of whether they did the required major and minor edits. I graded the students on participation, and not on the quality of their edits. Once I signed off on it, they do not have to edit it further.) (If the solution to a problem is correct, I put a red checkmark underneath it. After you have written the solution, you should remove this banner. This homework problem (or a part of this homework problem) has not been started. Once you make the changes, you should remove this banner. Please read the discussion there for ideas on improving the writing. The suggestions are described on the talk page. I have suggested improvements for this text. Once you have cleaned things up, you should remove this banner. Look on the talk page for more information. It might need better math formatting or structural repair. When you have corrected the error, you should remove this banner. ![]() There is probably a discussion of the error on the talk page. There are one or more errors in this solution. I wrote comments on the “talk page” and added banners (complete with goofy clipart) underneath each solution. Periodically I went through the wiki and read the solutions. Starting a new solution, but not making much progress.Modifying text to conform to our style guidelines.Correcting all typographical errors in a solution.Correcting all mathematical errors in a solution.Typing in the statement of a problem and a complete solution to a non-assigned problem.Fixing or cleaning up a proof is not sufficient for a major edit, it must be modified in a fundamental way. Making substantial changes to an existing solution.Typing in the statement of a problem and a complete solution.All of the problems were ones that I had assigned for homework, but I waited until after the students turned in their homework to list the problems on the wiki.Įvery couple of weeks (once we’d accumulated enough problems) I required each student to contribute one major edit and two minor edits to the wiki. I chose only problems that did not have answers in the back of the book. As the semester progressed I listed the problems that needed solutions. I made a page for each section of the textbook. I used the wiki as a place for the class to create an online solution manual for the homework. (Here’s a Wikidot LaTeX help page that I created.)ĭiscrete Mathematics is our gateway course to the mathematics major, so it is in this course we teach the students how to write mathematical arguments (proofs). (I did this for Discrete Math because I figured the textbook author wouldn’t want the solutions available on the web.) Also, one of the deciding factors for me was that you can write mathematics in Wikidot using a modified version of LaTeX. You can make the wiki private if you want to. Their wikis are free and ad-free for educational use. In the Knot Theory class each student had a “pet knot” and created a wiki page containing biographical information about their knot. In the Discrete Mathematics class the students collaborated to create a homework “solutions manual” on the wiki. I have used wikis in three of my classes: two Discrete Mathematics courses (Fall 2008 and Fall 2009) and one Knot Theory course (Spring 2009). A website that allows the easy creation and editing of any number of interlinked web pages… are often used to create collaborative websites, to power community websites, for personal note taking, in corporate intranets, and in knowledge management systems.
