The Effect of the Australasian Parliamentary Debate Technique on Students’ Argumentative Speaking Ability

ABSTRACTThe goal of this research was to investigate whether the use of the Australasian Parliamentary Debate had an impact on students’ argumentative speaking ability. The method was quantitative with a quasi-experimental design, and the participants of this research were SMAN 29 Jakarta 10th grade social students in the academic year 2017/2018. They were X IIS 2 as the experimental group and X IIS 3 as the control group, consisting of 32 students for each group. Convenience sampling was used to select the participants for this research, and the data were collected using an oral test. The argumentative speaking rubric was used to assess the students’ argumentative speaking ability in the pre- and post-tests. The results of statistical hypothesis testing, using independent sample t-test, found that the t-value was 2.23 on the significance level of 5 percent (α = 0.05), whereas the t table was 1.99 or tobserve > t table. H0 was therefore rejected and Ha was accepted. This finding shows that the use of the Australasian Parliamentary Debate has a positive effect on students’ ability to speak argumentatively.ABSTRAKTujuan dari penelitian ini adalah untuk menginvestigasi apakah penggunaan the Australalasian Parliamentary Debate memiliki pengaruh positif terhadap kemampuan berbicara argumentatif siswa.
