Description of DLAB •  Multiple choice, ~90 minutes •  Range 12-164, mean 100, SD 15 (~92, SD

~21 for 143K cases; current DLI means ~112-114)

•  Four parts – Bio data – Spoken stress – Deductive rule application –  Inductive pattern application

Page 7: DLIFLC STUDENT PROFILES - UT Liberal Arts · • Correlations of DLAB and outcome data – Consistently significant – Restriction of range affects magnitude • Eight-year data

RESEARCH BASE

•  Carroll’s four components – phonetic coding ability – grammatical sensitivity –  rote learning ability –  inductive language learning ability

•  Other FL aptitude tests – MLAT (Carroll-Sapon) – PLAB (Pimsleur)

How well does it work?

Very well, thank you – Language Skill Change Project, mid-1980s

– Army Research Institute, 2000-2001

– DMDC study, 2007

– DLIFLC program data, early 1980s to present

LSCP* •  1903 US Army students •  Korean, Russian, German, Spanish •  Eleven blocks of predictor variables •  Forced order-of-entry MRA of L, R, S,

course completion •  DLAB added variance, especially for

ARI Attrition Study

•  Tracked 237 beginning students for a year

•  From ARI PI’s outbrief:

–  As in past, DLAB is best predictor of attrition DLAB 98 or less = 32% attrition DLAB 99 to 116 = 20% attrition DLAB 117 or more = 10% attrition

–  Of DLAB scores above 117, 98% had prior language training Prior language training = 17% attrition No prior language training = 35% attrition

DMDC Study, 2007

•  Examined AFQT and DLAB as predictors of language learning success at DLIFLC

•  Employed three samples, using Markov chain Monte Carlo procedures and Bayesian modeling

•  Findings: AFQT < DLAB < Multiple Hurdle

DLIFLC Program Data

•  Correlations of DLAB and outcome data – Consistently significant – Restriction of range affects magnitude

•  Eight-year data set: Ss meeting the DLAB minimums have… – Lower attrition rates – Greater success rates (2/2/1+)

•  Caveat: High aptitude is a predictor—not a guarantor!

Motivation, Choice, and Outcomes

•  Does it matter whether you get a language you wanted?

•  How important is motivation to ultimate success at DLIFLC?

Who Studies What?

•  Constraints – Minimum DLAB requirements (95, 100, 105,

110) – Needs of the Service

•  Timing – Pre-arrival – Post-arrival

Page 17: DLIFLC STUDENT PROFILES - UT Liberal Arts · • Correlations of DLAB and outcome data – Consistently significant – Restriction of range affects magnitude • Eight-year data

Upon Arrival in Assigned Language Department

Page 18: DLIFLC STUDENT PROFILES - UT Liberal Arts · • Correlations of DLAB and outcome data – Consistently significant – Restriction of range affects magnitude • Eight-year data

Does It Matter?

•  Study 1: FY90 – FY94 graduates in 8 languages

•  Study 2: FY01-FY09 graduates in 9 languages

•  Six languages in common: – Arabic, Chinese (M), Korean, Farsi, Russian,

Spanish

Methodology •  Compare “choice” responses to language

learning outcomes – Three variants of coding choice responses:

•  All five options •  “5” vs “1-4” •  “5-4” vs “1-3”

– Outcome measures: Listening, Reading, Speaking, and Success (2/2/1, 2/2/1+)

– Partial correlation and chi square analysis – Visual inspection

Page 20: DLIFLC STUDENT PROFILES - UT Liberal Arts · • Correlations of DLAB and outcome data – Consistently significant – Restriction of range affects magnitude • Eight-year data

Findings

•  Distribution of Responses

•  Relationships of Responses to Outcomes

Comparison of Responses

Page 23: DLIFLC STUDENT PROFILES - UT Liberal Arts · • Correlations of DLAB and outcome data – Consistently significant – Restriction of range affects magnitude • Eight-year data

Relationships with Outcomes

•  Earlier Study –  Most correlations non-significant or too small to

matter –  Most chi squares non-significant –  Much variation across languages and skills

•  Current Study –  More significant chi squares –  Much variation across languages and years

•  Caveat: What does “choice” item measure?

Page 24: DLIFLC STUDENT PROFILES - UT Liberal Arts · • Correlations of DLAB and outcome data – Consistently significant – Restriction of range affects magnitude • Eight-year data

Another Look at Motivation

•  Language Skill Change Project – 1903 students, 4 languages – Multiple Regression, 9 blocks of predictors

•  Forced order-of-entry •  Attitude-Motivation measures in blocks 6 and 7

•  Motivation at start less predictive than motivation during

•  Cognitive variables most predictive
