One of the most controversial subjects in the field of foreign language research is grammar teaching which plays an important role in English language learning. Although different studies have investigated the explicit and implicit instruction of grammar, a few studies have been conducted to explore the effect of explicit and implicit instruction through Telegram. The aim of this study was to compare explicit and implicit grammar teaching through a kind of mobile app that is Telegram and compare and analyze explicit grammar instruction and implicit grammar teaching strategy. The participants of the study included 30 EFL learners who were divided randomly into two groups: explicit and implicit groups. A pretest and posttest were applied to measure the effectiveness of implicit and explicit methods of teaching grammar. The findings of the study indicate that explicit teaching of grammar is more effective than implicit teaching. The researchers believe that teaching grammar through deductive way is more successful than inductive method but Ling (2015) believed that in explicit grammar teaching, students concentrate on language forms and they can make correct sentences grammatically but students are not able to communicate in English but in implicit grammar instruction, students have more interaction with teacher and in fact implicit teaching can provide more relationships among teachers and students.
