Video Game use – exponential increase

A great deal of some kind of learning no doubt happens

But can targeted learning be made to happen?

Can we exploit this trend rather than fight it?

3

Many learning claims get made

4

Few games have specific learning goals

Claims are about “new ways of learning,” not about any particular content

Few (any?) claims are based on empirical investigation

But more in glossy books than dull research papers

5

To design a game with concrete learning goals

Based on learning principles

In one’s own research area And investigates its effects

empirically

An interesting opportunity therefore…

7

Game contains all the non-specialist words of English Sequenced by frequency/range in the BNC

Yes-no test determines start-point in sequence Words are introduced in six coordinated word games Games focus on

Form Meaning Verbal efficiency (speed of access)

Words are dropped only after six correct uses Principled recycling

Games are integrated within a tutor-model Choice of tutor Goal setting, record keeping, error review

Game incorporates a level-appropriate dictionary CALD

Belief: Discovery is not a sufficient strategy to grow an L2 lexicon

Some type of vocab focus is demonstrably necessary

Computer /video game is an ideal start to this job

Although maybe not finish

Content – 3 strands

1. Form of words

17

2. Meaning of words

19

3. Processing speed

All packaged in a small box

… and announced to the world in a huge publicity campaign -

21

Are more word meanings known both immediately + after delay

Are more words used in oral production

Are words accessed more quickly?

Research Questions

Following substantial use of the game…

22

Grade 6 primary school in suburban Montreal Feb-June 2007

Two intact classes, same teacher, n=50 Condition 1: both groups get to use game Condition 2: testing sessions not to exceed 1 hr

60%+ immigrant children, some quasi-bi/tri-lingual French, English, another

Instruction is in French, 2 hrs/wk ESL

Game is integrated into ESL classwork Parents solidly behind experiment

DS players + game disks from Ubisoft

Subjects and setting

23

1. For meanings known Paul Nation’s BNC-based 14k

Levels test 10 levels used, then 5

2. For words used Boy, dog and frog story (Mercer) Analyzed with VP-kids

3. For word access UNESCO method

– Read words aloud from 60-word list in fixed time

50

Are more word meanings known both immediately + after delay

Are more words used in oral production

Are words accessed more quickly?

Research Questions

Following substantial use of the game…

51

For this population, results are significantly and meaningfully positive on all three measures

Esp. compared to baselines e.g., Milton & Meara (1995): 550 wds/yr

in classroom on recognition measure

But paradoxical

Lexical development is at opposite ends of the spectrum Recognition – gains throughout first 5k Production – gains in first 250 words

Conclusions

52

Source of productive gains unclear Learning or activation of existing knowledge?

Apparent confirmation that lexical access is trainable Small effect for practice with format; big effect for time-

pressure processing• As known since SkiJump days but never widely exploited

First successful use of Levels Test as pre-post measure

Unsurprising since game and test derive from same wordlists

Conclusions 2

53

Significant prior vocab knowledge from somewhere 2350 known words at pretest

… but not in use

Frog stories of 100 toks / 40 fams• (cf. age 6 NS: 350 toks / 91 fams,)

… and distributed so that half the words are unknown at key 1k + 2k levels (# 32)

• Which explains weak reading levels• Which reflects neglect of lexis in MEQ curriculum

Conclusions 3 – Interesting portrait of Quebec ESL learner

54

Can Word Coach compensate for any of this?

Effects of moderate-to-heavy users of the game

Word knowledge: 1k and 2k levels rise to equivalent age native speaker (NS) levels (80% plus)

Word use: Story size of 250 word, pushing age= NS average of 350

Access: 85 words read aloud/minute is approaching NS average of 110

A lot of compensation in a short time!

Conclusions 3 – Interesting portrait of Quebec ESL learner

55

Two possible directions

1) More of the same

Game 2 which extends Word Coach approach into collocation, context, idioms, specialized domains

2) Integration of Word Coach principles (whole lexicon, sequence, recycle, review) into a full adventure narrative

“Look out ! They’re shooting from the balcony !!”

Next steps for Word Coach

56“Look out – the other one’s in a garbage can!”
