Improving students' pronouncing of Friction Consonants through dubbing Video at the first grade of SMA Negeri 1 Way Jepara

The current study aimed to find out whether the use of dubbing video technique could improve students' achievement of pronouncing the Friction consonants. It was conducted at the first grade students of SMAN 1 Way Jepara, in the academic year 2021/2022. The study was a quantitative approach with the design of true experimental where two classes (experimental and control classes) were involved (X IPA 1 and 2), each of which consisted of 30 students. The data were collected through the pretest and the post test in the form of friction consonants list for students to pronounce. The gain scores of both classes were compared using SPSS software 22. The results showed that i) dubbing video technique significantly improved the students' achievement of pronouncing friction consonants with significant level 0.05, and ii) there was statistically significant difference achievement of friction consonants between the students taught through dubbing technique and those through conventional learning method without dubbing video technique. The result showed that the students taught with dubbing video techniques had better achievement than those with conventional learning techniques. This suggests that dubbing technique facilitates students to improve their achievement of pronouncing friction consonant sounds.
