The teaching of vocabulary is essential in the world of teaching English as a foreign language (EFL). EFL learners have problems in learning vocabulary. To attract the students' attention, the teachers should have adequate teaching methods. One of the teachers' efforts to engage the students is by applying ESA (engage, study, and activate) through Quizizz to find out the enhancement of students' vocabulary knowledge. The study was done in a public junior high school. This was a quantitative research with a sample of 65-students. The students were divided into two groups as experimental and control group. The result of this study showed that both groups have enhanced their vocabulary knowledge. Also, there is a significant difference between the experimental and the control group. Student responses through the questionnaire show they like the learning model. Therefore, it can be concluded that ESA through Quizizz games are effective methods for teaching vocabulary, and also the use of Quizizz can be done at all academic levels from the primary to the tertiary level. The students enjoy and are excited to learn through this model.
