How do Oral Rehearsals and Peer-feedback Affect Monologic and Dyadic English Speaking Tasks?

indicating that the more L2 learners engage in individual oral rehearsals, the more they are likely to improve their monologic speaking ability.In the authors' subsequent study (Nagasaki, Armitage, & Orimoto, 2020) they examined whether, combining individual rehearsals with interactive rehearsals, led to the development of 60 first-year Japanese university students' communication ability.The results showed, that both individual and interactive rehearsals are significant predictors of improving students' scores in a paired conversation test, and different types of rehearsals developed different linguistic aspects.Specifically, interactive rehearsals were likely to improve their scores of starting and ending a conversation (e.g., greetings and small talk) and attitude (e.g., making eye contact) in the conversation test, whereas individual rehearsals were likely to improve their scores in expressing ideas and vocabulary.These results provide crucial implications for teaching and learning, namely; that L2 learners can benefit from both types of rehearsals.However, since the learners in this study engaged in both types of rehearsals in the same period of the time, whether doing only interactive rehearsals or only individual rehearsals promotes L2 communication ability is unknown.The present study aims to investigate the issues raised in the authors' previous research: that is, whether doing only individual rehearsal can promote monologic speaking (speech) ability as well as L2 communication ability and whether doing only interactive pair rehearsal can promote these two types of ability.The study also aims to determine what learning opportunities and language aspects L2 learners attend to when doing self-review and receiving peer-feedback. The Study Research QuestionsTo examine the effects of the two types of oral rehearsals more precisely and noticing through selfreview and peer-feedback, the following research questions were established: RQ1: Do oral rehearsals promote L2 communication ability?Specifically: a.Does doing only pair rehearsals promote L2 communication ability?, b.Does doing only individual rehearsals promote L2 communication ability?, c.Does doing both types of rehearsals promote communication ability even more?RQ2: Do oral rehearsals promote L2 speech ability?Specifically: a.Does doing only pair rehearsals promotes L2 speech ability?, b.Does doing only individual rehearsals promote L2 speech ability?, c.Does doing both types of rehearsals promote L2 speech ability even more?RQ3: What do L2 learners notice through self-review and peer-feedback?*Communication Strategies: fillers, listener expressions**, natural repetitions, rephrasing, paraphrasing, turn-taking expressions, negotiation of meaning, or
