Slide5

The data models

Tell us about the

data models itself

what do we see?

Tell us about the process of findings the

data models

Tell us about the value of the

data models

Slide6

The papers

Slide7

Onward

Identify whether and how

naming play

a role in your system, and bring a printed copy documenting your findings to class next week

Be prepared to talk about your findings

Be prepared to talk about the process of identifying your findings

Be prepared to talk about the value of your findings

Slide8

Onward

No class May 21

Read

all of the papers listed on the web site for May

28

Prepare

two

questions, observations, or assertions about the papers and their overall content (printed, with name and student id)

Slide9

First design exercise – structure

In a team of 4-5, spend two sessions of 1½ to 2½ hours each designing at the whiteboard

Be mindful of the expert practices

Videotape your sessions

Slide10

First design exercise – deliverables

Produce a document detailing your design as it exists at the end of the second session

what are the design decisions so far

what is still left to

do

no designing after the two sessions are done, incomplete designs are ok

Document, with

seven short

video

snippets, when

and how you exhibited certain expert practices while you worked at the

whiteboard

DVD or memory stick (to be returned)

a document that indexes/explains the snippets

Slide11

First design exercise – prompt

Design

ClimbingRoutes

, an app that:

allows mountain climbers to contribute new climbing routes to an ever-expanding database of such routes

allows mountain climbers to select, view, and navigate a climbing route

ClimbingRoutes

is primarily meant to be a visual app
