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 My Word Coach - description
8 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 My Word Coach - philosophy
20 All packaged in a small box … and announced to the world in a huge publicity campaign - http://mywordcoach.us.ubi.com
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 Instruments
31 Results To note first: Equal game use between groups (despite considerable variance)
32 Results 1 1a. Levels Test (pretest, both groups, no diffs) About 2350 word meanings known from first 5000 families but only just over half at key 1k level (600 words, SD 150)
33 Results 1b. Levels post-test Significant gains for first 5 k-levels combined at T3
34 Results 1c. Levels Test (3 times, both groups)
35 Results – Levels Test - Summary Initial state: No significant difference Baseline (602, T1-T2): No significant difference Following game use 601: 459 words average gain, **sig – but at T3, not T2 602: 178 words average gain, * sig Note: These are average gains Incorporating wide range of variance
36 Results 2 2a. Frog stories – new words in use
37 Results 2b. Frog stories – where are these gains?
43 Results – Frog stories - Summary Initial state: No significant difference (n.s.d.) - In # families used - In # tokens (=story size) Baseline (602, T1-T2): n.s.d. Following game use Despite variance: - Average 3 new word families - Average 35 more word tokens - Average 45% reduction in # of L1 words used
44 Results 3 3. Access – number of words read in 1 min.
45 Results 3. Access – number of words read in 1 min.
46 Results – Lexical access - Summary Initial state: No significant difference (n.s.d.) Baseline (602, T1-T2): Small but sig gains * Practice effect Following game use Despite variance: - Av. 23 more words read/minute - Statistically significant **

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!”
