Paired-samples t-test comparing the 24 experimental-group participants' IELTS speaking pretest and posttest after the PBL treatment; the article reports "a statistically significant increase" with t(23)=13.22, p=.00. No effect size is printed.

"A paired-samples t-test indicated a statistically significant increase from pre-test (M= M=15.75, SD= 1.15) to post-test [M=18.58, SD= 1.05, t(23)= 13.22, p=.00]"
