pptxPART 1. CRITICAL REVIEW
PART 2. REPLICATION STUDY
Song, M-Y. (2008). Do divisible subskills exist in second language (L2) comprehension? A structural equation modeling approach. Language Testing, 25 (4). 435-464
Hypothesis
Language proficiency most probably consists
of a general higher-order factor and several distinct
first-order ability factors.
The main purpose of this study
to investigate the factor structures of the WB-
ESLPE listening and reading test items with regard
to different subskills, using a SEM approach
Method
Small sample size : 110 test-takers scores
Creating 7/8 observed variables : item parceling
Structural equation modeling :
(Model 1) 1 unitary skill : COMP
(Model 2) 2 subskills; COMP + EXP, IMP
(Model 3) 3 subskills; COMP + TOP, DET, INF
Uni/multivariate normality evaluation, reliability estimate
ML by EQS
no report on scaling, covariance matrix, effect size
missing data fixed to 0 score
뵀2 statistics, 뵀2/df ratio(2), CFI(.90) , RMSEA (.08)
Analysis & Findings
Different factor structures between listening and reading skills
: due to test-takers high proficiency level and task characteristics,
More holistic and integrated subskills required in listening skill
