This research investigates the Think-Pair-Share (TPS) technique effectiveness in improving students’ speaking skills in giving and asking for opinions, addressing a significant need for practical cooperative learning strategies. This study used quantitative approach with quasi-experimental designs involving 68 eleventh-grade students in total at SMA Negeri 15 Semarang in the second semester of the 2023/2024 academic year, divided into two groups: an experimental group (n=35) and a control group (n=33). Both groups were given a pre-test, followed by treatments with three meetings in each. After the treatments, a post-test was administered to determine the effectiveness. Based on the data, the control group’s, taught using the group discussion achieved an average score of 72.36 and the experimental group, taught using the TPS techniqe, scored 86.17. The experimental group’s N-Gain score was 62.29, which is classified as "effective enough". The Sig. (2-tailed) on the Independent Sample T-test value of 0.000 <0.05 shows the TPS technique has improved the students’ speaking ability, particularly in giving and asking opinions at a high level. These findings confirm that the TPS technique can substantially enhance students’ speaking skills, particularly in giving and asking for opinions, fostering a more interactive and encouraging active participation in the EFL classroom.]]>
