Form-focused discovery activities allow language learners to grasp various aspects of a target language by contributing implicit knowledge by using discovered explicit knowledge. Moreover, such activities can assist learners to perceive and discover the features of their language input. In foreign language teaching environments, they can be used for various teaching purposes. This study investigates "form-focused instruction" in developing implicit knowledge of a language by a poetry-discovery process. Although most language learners avoid poetry due to its complex linguistic and semantic components, poetry holds implicit knowledge (and other qualities) that make it an excellent means by which language rules can be learned. This study was aimed at defeating learners' prejudices about poetry by prompting their deep processing and creativity through the inquiries into the complexity of poetry's structure.
