THE EFFECTIVENESS OF UNO STACKO TO IMPROVE ENGLISH SPEAKING SKILLS

English speaking skills is a crucial aspect of language education in Indonesia, where English is treated as a foreign language. Despite its importance in global communication, students often face challenges such as limited vocabulary, lack of confidence, and insufficient practice opportunities due to traditional teaching methods. To address these issues, game-based learning (GBL) offers an innovative approach that combines educational benefits with engaging activities. This study investigates the use of UNO Stacko, a well-known game, as a tool to enhance English speaking skills among students participating in the English Club extracurricular at MTs Muhammadiyah 1 Malang.
The purpose of this research was to assess the impact of UNO Stacko on improving students’ speaking abilities. Using Classroom Action Research (CAR) based on the Kemmis and McTaggart framework, the study was conducted in two cycles consisting of planning, implementation, observation, and reflection. Ten students participated as research subjects, with data collected through pre-tests, post-tests, and classroom observations. The study evaluated improvements in students’ vocabulary, grammar, pronunciation, fluency, and task completion.
The findings revealed significant progress in students’ speaking skills, as the mean scores increased from 17.9 in the pre-test to 23.7 in the post-test. The integration of UNO Stacko not only enhanced vocabulary acquisition and fluency but also boosted students’ confidence and created an engaging learning atmosphere. These results highlight the potential of GBL, specifically UNO Stacko, as an effective instructional strategy for teaching English. Further research is encouraged to explore its application in other areas and with larger groups of students.
