During the last two decades, an increasing well-established line of work has underscored the concept of metaphor. Also, many studies have concluded that task-based instruction, as well as Focus on Forms, lead to desired levels of second language learning. Moreover, the use of L1 in learning L2 has also been highlighted. What seems to have gone unexplored though is investigating the effect of the use of collaborative tasks via L1 on learning figurative language. Moreover, the effects of negotiated interaction and reciprocal teaching-as two important task types- on speaking fluency have not been proved yet. Additionally, the impact of task-based and focus on forms instruction on metaphorical competence seems to have gone unexplored. Therefore, the current manuscript, in an attempt to fill the gap in the literature, contains three articles with the following titles: 1. Collaborative Translation Tasks: The Case of Figurative Language 2. Negotiated Interaction and Reciprocal Teaching:The Case of Speaking Fluency 3. The Effect of Task-based Instruction and Focus on Forms Instruction on the Development of the Metaphorical Competence of Iranian Upper-Intermediate EFL students
