  • 1. Presenter BiosFirst-year TESOL Doctoral students atthe University of Central Florida.Alison Youngblood has taught ESP,EAP, and K-12 in Japan and South Korea
  • 2. Theoretical FrameworkThe iBT speaking section is met with unfavorable attitudes by test- takers from across the globe (Stricker&Atali, 2010)Researchers also observed this negative attitude while teaching in an EAP
  • 3. Our SampleBased on ETS’s 2009 Score ReportLooked at the average composite score and average section score on the iBT and PBT listed by countrySample included scores from countries where both iBT and PBT were reported by ETS
  • 4. MethodologyResearchers believe it is logical to assume that composite scores include individual test takers’ multiple attemptsStatistical procedures used:1. Dependent t-test 2. Repeated measures
  • 5. Research Question 1Is there a significant difference in the mean composite scores for iBT and PBT?
  • 6. ResultsThe test was statistically significant t(143)=-2.65, p<.05. There is a significant difference in mean composite iBT scores (M=551.79, sd=25.87) and mean composite PBT scores (M=545.67, sd=38.05). The 95% confidence interval for the mean
  • 7. DiscussionOur results indicate that students on average actually score higher on the iBTThis challenges student perceptions that the iBT is ‘harder’However, the converted mean composite of 551.79 on the iBT is
  • 8. Even though the test showed significance, our effect size was calculated by eta squared and found to be .046. This means only 5% of the variance in composite scores can be attributed to test versionDifficult to make exact comparisons based on composite scores because of differences in
  • 9. Research Question 2Do students score significantly lower on the speaking section of the iBT in comparison to the other three sections?
  • 10. ResultsThere is a statistically significant difference in section score ( p<.05) on the iBT sections (F3, 429=95.21). 40% of the variance in score can be accounted for by section.
  • 11. DiscussionThe speaking section had the highest mean composite score (m=21, sd=1.99).The reading section had the lowest mean composite score(m=18.80, sd= 3.28)The is the opposite of student
  • 12. LimitationsSmall sample sizeUse of mean composite scores instead of individual scoresUnable to determine the number of individuals who took the test multiple times versus the individuals who only attempted
  • 13. Further ResearchStudies exist that compare the CBT and PBT, but unable to find studies that compare the PBT to iBTDirect research comparing the iBT to PBT could be helpfulObtain individual scores
