Patterns Workshop

• We have a set of case stories– Completed stage 1

• Challenge: Generate Design Patterns• Key questions

– What is a pattern?– Why generated it?– How to generate it?

What is a pattern?

• At is simplest, it is a– Generalised solution to a problem– Follows a specific structure

C o n t e x t

Problem Solution

When, Where, Who

What are we trying to achieve / solve?

Cookbook: ingredients, procedure, expected

outcomes

“if I copy a dress, I can only create the same dress. If I have a pattern, I can create many dresses” (Yim Ping LENDEN)

10

Why generate patterns?

• Need a way to collaborative produce and share knowledge of practice

• Use this knowledge to inform the development of new TEL artifacts (technologies and pedagogic resources)

• Integrate expertise across disciplines

11

How to generate patterns?

• Two-stage process• Start with this partial template

– Problem– Context– Solution

• Identify common features across case stories– How?– Let’s talk through an example

12

Case study 1: CoMo

13

Case study 2: MiGen

14

How do I determine common features?

• Identify the problem addressed– Supporting knowledge construction

• How is it addressed?– Through communication around artifacts

• Identify the key aspects– Students – Setting – Artifacts

• Identify the forces underlying the problem

15

Underlying Forces

• Knowledge construction through communication

• Communication is a powerful driver of learning– Prompts learners to articulate their intuitions and

in the process formulate and substantiate them– Enables learners to share knowledge and question

• Communication is even more powerful when building on experience

16

What are the common features?

• Artifacts are produced– CoMo: images of practice– MiGen: mathematical models

• Artifacts are shared– CoMo: online image blog– MiGen: shared on school network

• Artifacts are discussed in conversation– CoMo: f2f with tutor – MiGen: online with teacher

17

What are the key features?

• Conversation mediated by artifacts produced by students using technology

• Let’s make the language slightly simpler – “Artifact” ~ “object”– “Conversation” ~ “talk”

• Memorable title!

18

“Objects to talk with” Pattern• Problem

– How to support learning through online discussion of a shared activity

• Context– Tools which allow learners to communicate

• Solution– Learning activities often involve the use or construction of

objects – When providing tools for learners to discuss their

experience, allow them to easily include these objects in the discussion

– The medium should support a visual (graphical, symbolic, animated or simulated) representation of the objects

19

Pattern Generation

• Pattern generated from cases• CoMo and MiGen are instances of this pattern

– But there can be many more …

22

The Plan

• Map the common features to core template

• Illustrate the big idea

• Force mapping

• Sequence / block diagram of solution

• Define context as per concept map

• Fill in the blanks

23

The core template

• Context– Primary, English, PBL, Implementation

• Problem (pick one!)– We want to do A under condition B but are

constrained by C

• Solution

(in any order that

works for you) C o n t e x tProblem Solution

24

Draw it!

25

Force MappingForces: constraints or factors that influence the problem.

The difficulty of solving the problem arises from tensions between competing forces.

• Name the forces

• Give them icons

• Plot the links and mark + / -

26

Forces

• Actors

• Beliefs

• Conditions

• Desires

27

Sequence / block diagram / flowchart

28

Fill in the blanks• Support

– Source Case

– Other Cases

– Theoretical justification

• Related patterns

• Notes, Links and References

• Liabilities, potential risks, extensions, expected side-effects
