Final Grading Details

in Posts
Here is some information on where the final grades came from… DE13 Self-Evaluations Thanks to everyone who did this (almost everyone). They were pretty uniformly insightful and thoughtful. They gave me lots of ideas. I will fight the urge to say “but it was that way for a reason” - and instead say “OK, need to work on that in the future”. And there were some great specific things that I can do differently. Read more…

Final Forms

in Posts
Some notes on the final handins - details on what the forms look like so you can be prepared. The detail instructions are available at Final Project Handins. It is probably best to have your answers ready when you fill out the Canvas forms. The Handin Form Note: you can turn in two files: a PDF (your document), and a ZIP (anything else - it should not include your document, although it can include a supplement document). Read more…

The Week in Vis: Week 15

in Weeks in Vis

The last week of the semester…

The big thing is, of course, the project. Instructions for the final handin are at Final Project Handins. Please consider signing up to give an in class presentation.

In class… I will give a “presentation on presentations” on Monday. This is more about the “general skill” of giving presentations, rather than something specific to Vis. On Wednesday, we’ll have some students give presentations. (we only have time for a few presentations)

Final Project Handins

in Posts
The final projects must be turned in on (or before) Friday, December 16th. There will be a Canvas survey for turning the assignment in. Only one person per team should turn in the final project. The handin will include a writeup (up to 4 pages + references) and “artifacts” (software, a portfolio, video, …) These are detailed below. Self-Evaluations for the project must be turned in on (or before) Sunday, December 18th. Read more…

The Week in Vis: Week 14 (Dec 5-9): Graphs

in Weeks in Vis

The last full week of the semester!

In some ways, this is a normal week. We have a big topic (graphs - in the sense of networks, not in the sense of “line graph”). But, since you’re probably deep into the project, we’ll adjust expectations accordingly.

To give you more time to focus on the project, we won’t have an online discussion this week. Instead, use this as an opportunity to contribute to the Project Theme Discussions. Please be careful though: join a group before posting (if you post before joining a group, it goes into a “no-mans-land” where only people who haven’t joined a group can see it).

The Week in Vis: Week 13 (Nov 28-Dec2): Evaluation

in Weeks in Vis

The week after Thanksgiving… we can sortof get back to a normal schedule.

This topic for this week is Evaluation. I’ll talk about it in lecture on Monday. The readings are important. You can read them before lecture or after (I’ll go through the main points - it’s stuff you will need to see more than once). The readings are very reduced for the project. But, there will be a “Design Excercise” related to both the project and the readings for the following week.

For Wednesday’s lecture, the topic is “the random stuff that doesn’t fit anywhere else.” It might be more on evaluation. I may talk about 3D and animation - because there is simply no other day to talk about them, and I feel a need to talk about them. Or maybe I’ll talk about the SciVis topics that we simply don’t get time to cover in class, but I feel must be at least mentioned in a Vis class.

In terms of the project: there is a “check in” this week - it’s officially due on Tuesday, but it is OK if you turn it in before Friday Dec 2. That will give you more time to make progress. Note: only one member per team needs to fill out the form, but all team members should do the survey to indicate who is doing the form for them.

The Weeks in Vis: The Last Weeks

in Posts
This posting is meant to give you a sense of what is planned for the last weeks of class (post Thanksgiving). Class is dominated by the project: the design exercises are all parts of the project, and there is something due each week. There are some seek-and-finds, and one online discussion left, but we’ll skip those at the end (to make more time for projects). Week 13: Evaluation The topic is important: how do we know that visualizations (or visualization systems or visualization ideas) are good? Read more…

The Week in Vis: Week 12 Color, Projects, Thanksgiving

in Weeks in Vis

It’s Thanksgiving week. The schedule is changed a little. I hope everyone has a good holiday.

This week we have a big topic: color. It seems so central. It seems so basic. But it turns out to be remarkably complex (and important). We can only scratch the surface. But, the amount we’ll do is also constrained by its Thanksgiving week, and the course project is starting (and I want students to focus on that).

Hints for Good Figures (how to do well on DE9)

in Posts
Here are some hints for how to do well on Design Exercise 9: Visualization Hand-Ins - but really, they are advice on how to make good figures generally. These are generated from the experience of grading Design Exercise 5: Aid Data Handin. We discussed most of them in class. Don’t rely on the rationale. Yes, you can argue for why what you are doing are good choices (and you need to do this for the assignment), but a good figure doesn’t need the rationale to explain why it is a good figure.

Grading Information for Aid Data Design Exercises (DE3-DE5)

in Posts
The grading (assessment, not critique) for the “Aid Data Design Exercises” puts together all the scoring information from the 3 assignments (drafts, critiques, and final handins). Short version: your final score is a number between -2 and 2, where 0 is meant to be “expected” (where the mean is). This doesn’t tie neatly to grades. Initial thoughts This turned out to be more complicated than I had thought it was going to be. Read more…
