This case study aimed at identifying barriers encountered by an English teaching who taught in a large class and how he dealt with them. The participant of this study was an English teacher in a private owned school and the number of students he taught was more than 30, which is considered a large class for language learning. An in-depth interview and classroom observation were conducted to gain data. Analysis was done in an iterative way. This study revealed seven issues which were encountered by the participant in his EFL class. All of which were associated with the difficulty to 1) evaluate and provide individual feedback, 2) control students'(discipline), 3) achieve learning effectiveness and learning outcomes, 4) engage students to the lesson, 5) pay individual attention. Other issues occurring in his class were the use of local language by the students in EFL class and decreased interest (motivation) to learn English. In order to tackle these issues, the teacher employed two strategies, namely: 1) using a variety of games and 2) setting an outdoor English class in order to attract students' attention.
