Tutorial Description

Modelling enjoys a central position in object-oriented software development.

Unfortunately, techniques for modelling, and the industry standard Unified Modelling

Language (UML) in particular, have been criticized as being too complex in teaching

situations. The tutorial will present a mixture of techniques for overcoming this

complexity in teaching and learning UML modelling based on the use of the Ideogramic

UML tool (http://www.ideogramic.com/products/) for gesture-based, collaborative

modelling.

Overview

The tutorial will discuss common problems with introducing object-oriented modelling.

The presented teaching techniques and examples will make use of

Ideogramic UML

: a

tool for collaborative and individual UML modelling. Its most effective use is on an

electronic whiteboards (Figure 1, left), and it is operated using gestures drawn with a pen

or a mouse (Figure 1, right). Drawing a box, e.g., creates a class and drawing a line

between two classes creates an association between those classes.

Gesture Recognition

Throughout the tutorial, we will discuss attack problems of

extent, complexity,

and

usability

of modelling notations by focussing on four types of teaching scenarios:

Lecture use.

A lecturer explains modelling using Ideogramic UML. As on an

ordinary whiteboard there is a close connection between the lecturer’s actions and

the results of these actions.

Peer instruction use.

Teaching assistants and students use Ideogramic UML to

present and develop solutions interactively.

Peer group use.

Students use Ideogramic UML when working in project groups,

solving an exercise collaboratively.

Individual use.

Ideogramic UML is used on an ordinary PC as a modelling tool

combined with all the scenarios above.

At the end of the tutorial, participants should have insight into collaborative teaching

techniques for modelling, have ideas for exercises and assignments, and know how

Ideogramic UML can be used concretely to teach modelling.

Part of the tutorial will be hands-on experience with gesture-based modelling. The

equipment needed for the set-up is relatively inexpensive: a projector, a desktop

computer, and an electronic whiteboard. The electronic whiteboard consists of a device

that can be attached to an ordinary whiteboard and it is available from a number of

manufacturers such as tool-tribe (www.tool-tribe.com), Mimio (www.mimio.com), and

eBeam (www.e-beam.com) with prices starting at 500 US$. All participants are provided

with free educational licenses for Ideogramic UML.

Equipment Needed

We will bring a projector, electronic whiteboard equipment, and laptop computers. The

electronic whiteboard equipment needs to be attached to an ordinary whiteboard (at least

2 meters x 1,5 meters in size) and the projector needs to be able to be placed so that it can

project onto the whiteboard.
