For most of my inquiry-based learning (IBL) proof-based courses, I typically assign two types of homework assignments:

1. Daily Homework
2. Weekly Homework

I’ll briefly explain each of these.

# Daily Homework

The Daily Homework is assigned each class meeting, and students are expected to complete (or try their best to complete) each assignment before walking into the next class period. All assignments should be carefully, clearly, and cleanly written. Among other things, this means that the work should include proper grammar, punctuation, and spelling. However, the work done on these assignments is not intended to be perfect. The Daily Homework generally consists of tasks (e.g., completing exercises, proving theorems) from the course notes. On the day that a homework assignment is due, the majority of the class period is devoted to students presenting some subset (maybe all) of their proposed solutions/proofs to the tasks that are due that day. Students are allowed (in fact, strongly encouraged!) to modify their written work in light of presentations made in class; however, they are required to use a felt-tip pen, which I provide at the beginning of each class. Students can annotate their work as much as they like and there is no penalty for using the felt-tip pen. Students submit their their work at the end of class and the assignment is graded on a $\checkmark$-system. Whether the student receives a $\checkmark-$, $\checkmark$, or $\checkmark+$ depends on how much work they had completed before they walked in the room. The felt-tip pen strategy works amazingly well.

# Weekly Homework

In addition to the Daily Homework, students are also required to submit two formally-written proofs each week. During week $n$, students submit any two problems marked with a * that were turned in during week $n-1$ for the Daily Homework. The *-problems are typically a subset of the medium to difficult proofs. The students are required to submit a PDF of their write-ups, and in general, the Weekly Homework assignments are due on a non-class session day (so that they don’t interfere with the Daily Homework). One huge advantage of this approach is that students are forced to reflect on the previous week’s work and it allows them another opportunity to learn the material if they didn’t master it the firs time.

If you’d like to know more about my approach to Daily and Weekly Homework, as well as the felt-tip pens, check out the slides for this talk. In the future, I plan to write a more extensive blog post about the advantages of the felt-tip pens and the multiple rounds of revision that the Weekly Homework promotes.

# Using LaTeX for the Weekly Homework

I either require or strongly encourage my students to type up their Weekly Homework assignments using LaTeX. In case you don’t already know, LaTeX (pronounced “lay-tech”, or sometimes “la-tech”) is a markup language that is the standard for typesetting mathematics (and other technical fields). Most people find it difficult to get started with LaTeX and my students are no exception. To minimize some of the initial difficulties, I encourage them to use either ShareLaTeX or ScribTeX, which are online LaTeX editors. This way students do not need to worry about installing the LaTeX backend and an editor. In addition, both ShareLaTeX and ScribTeX allow my students to share documents or folders with me. Whenever they are having difficulty, I can just take a look at their file and either make a comment right in the file or do a quick debug. In the past, most of my students have used ScribTeX, but I think that I’ll start steering them towards ShareLaTeX. Another way that I try to reduce the LaTeX start-up cost is by providing my students with a LaTeX Homework Template (see below).

This template is set up exactly how I want the Weekly Homework to look. I also provide a minimal amount of guidance, as well as some examples in the template. Here is what the resulting PDF looks like.

Feel free to use the template and if you have ideas for improvements, I’d love to hear about them. Lastly, I’ve written a Quick LaTeX Guide to help my students get started with the actual writing of LaTeX.

Update: As of September, 2012, it looks like ScribTeX and ShareLaTeX are joining forces. It’ll be interesting to see what impact this has.

### 5 responses to LaTeX Homework Template

1. You should really include a preview of the generated file in the article.

Aside from that, good stuff. Nice to see teaching staff finally catching up using great technologies like github and blogs. Oh, nice profile picture as well! Carry on…

• I’ve added a preview of the PDF. Thanks for the suggestion.

2. On another note, when navigating to “Teaching” on this site, following either link below “Under construction….” results in 404.

• Ah, thanks. I forgot that I renamed a directory. It’s now fixed.

3. Very nice to see people spreading LaTeX. I didn´t know about that sharelatex thing and it just blow my mind!
