In today's era, students are highly fond of technology. As a result, lecturers are required to be able to create relevant learning experiences through the use of technology. The use of technology in flipped classrooms is one of them. For engineering students, mastering English for Engineering is a hard work. Therefore, teachers must be able to identify an appropriate and effective technique for students to improve their English proficiency. This research intends to investigate the use of edpuzzle and Quizlet in flipped classroom of an ESP instruction. This study used a mixed methodology. With the aid of questionnaires and interviews, information was gathered. Statistical descriptors were used to the acquired data for further analysis. The results indicated that engineering students viewed the flipped classroom method well. In addition, this study discovered that the Flipped Classroom Method Using Edpuzzle and Quizlet in an ESP course had enabled Engineering students to develop solid social contacts in which they can learn, teach, and share knowledge.
