Abstract The main objective of this study was to explore EFL teachers’ practice of group work in teaching English as a foreign language. To this end, Motta Secondary School, Motta Ayer Marefiya Secondary School, Enessie Secondary School, Keranyo Secondary School and Sedie Secondary School were selected by using purposive sampling technique as study area. Data were gathered through classroom observation and interview from the same ten English language teachers, who were chosen randomly by lottery system and through questionnaire from 25 teachers, who were selected by using comprehensive sampling. The obtained data, then, were analyzed qualitatively and/or quantitatively based on the nature of the tools and the items employed. The results of the study revealed that more than 68% of the teachers used group work as one of their teaching technique at least frequently and at most very frequently. The findings of the study, however, indicated that there were some teachers’ roles, which were not played by nearly half of the participants of the study. The study also showed that lack of knowledge about techniques of group work, lack of experience, and large class size were some of the factors, which can hinder the teachers from playing their expected roles effectively in using group work. The study also provided some possible recommendations, which were likely to alleviate the effects of those factors, such as maximizing the number of classrooms, preparing short-term training programs for teachers, and the likes. In addition, the need for group work activities to be carefully selected, designed, and evaluated was found to be given due attention so that group work could be implemented effectively.
