Abstract
Studying English is mandatory in many countries, including Indonesia, since English is one of the most generally spoken languages in the world today. This study focuses on productive skills since they reflect students' performance. This study offers valuable insights for future researchers focusing on enhancing speaking skills or conducting research utilizing the Cooperative Learning-Jigsaw Model. Speaking skills are chosen from the productive skills since the ability to speak is essential. This study used the pre-experimental design, so the sample used was only one class. Therefore, unlike a conventional learning method, there was no comparison class and no control class to strengthen the significance of the jigsaw in enhancing students’ speaking ability. The use of Jigsaw influences students' involvement in speaking. It increases their communication skills, as indicated by significant differences in pre-test and post-test scores seen from the mean. The majority of the sample succeeded in reaching a good category.
