Some class feedback so far….

I think more time should be allotted to complete

these surveys or emphasize that these surveys

are for feed back only and not graded.

I'd prefer shorter and more concise readings

with less congested detail, because a couple of

these readings have been VERY unbearable to

read.

— CMSC434 Student

It would be nice to learn about things such as

typography and specific examples of how to

implement good HCI. I see the differentiated

bold and italic font on your slides and noted it

is very effective and easy to read, but I'd like a

formal understanding of how to come up with

stuff like that on my own.

The [presentation] rubric was very non specific.

This may have been intentional so that we could

sort of try to present our proposal in the best way

we thought but I feel if there was a bit more

specific guidelines we could have developed a

better presentation.

— CMSC434 Student

Grading your own presentation is always

difficult/confusing, and not necessarily helpful.

— CMSC434 Student

If it isn't already done so (I haven't been able to

find it), it would be helpful to have a list of links

to the readings all in one place instead of

having to scroll through piazza to find them.

— CMSC434 Student

I feel one area that can be improved is giving a

clearer outline of the stages of our group

projects and what we expect to accomplish at

the end. I found myself confused at first about

what exactly we would be doing further down the

road with our projects.

— CMSC434 Student

So far, I really like the class and I feel like it's been

helpful for thinking about design not only for

the technical side of CS, but also art in general

(something that I felt was missing from the Studio

Art program at UMD).

(something that I felt was missing from the Studio

questions could be added for reading

assignments to help us get the most out of them.

— CMSC434 Student

In short, less reading assignments. Quiz was

very fair and acceptable and the lectures are very

good and enjoyable.

I think the class is very casual which I like.

I think the class is very casual which I like. But, I

just don't feel that the class hours is thought of as

very... academic.

— CMSC434 Student

I think the class is very casual which I like. But, I

just don't feel that the class hours is thought of as

very... academic. Probably during like 20 minutes

of the class, we can have some session where

everyone gets serious and starts taking notes

from the slides.

— CMSC434 Student

Also, Matt needs to learn how to not shake the

camera...steady hands young padawon :-D.

IDEO Method Cards are intended as inspiration

for practicing and aspiring designers, as well

as those seeking a creative spark in their work

IDEO Method Cards, http://www.cs.umd.edu/class/spring2013/cmsc434/protected/IDEOMethodCards.pdf

Learn Analyze the information

you’ve collected to

identify patterns and

insights

Look Observe people to

discover what they do

rather than what they

say they do.

Ask Enlist people’s

participation to elicit

information relevant to

your project

Affinity Diagramming Activity

1. We are going to diagram the HoF/S Piazza post

2. Write down ideas/observations onto post its

3. Start discussing relations/themes

4. Sort into themes spatially

5. Keep sorting and iterating until consensus forms

6. Create headers to describe themes
