18. In the final line of the dialogue,the teacher demonstrates which of the following?
Answer: D
The teacher demonstrates recasting.
In the final line of the dialogue, the teacher provides an example or reformulation of a student's incorrect language use, which illustrates the concept of recasting. This technique allows the teacher to model correct language usage without directly correcting the student.
A) Metalinguistic feedback
Metalinguistic feedback involves providing students with comments about the language form or structure used, rather than directly correcting their mistakes. This option is incorrect because the teacher's response does not focus on explaining the rules or concepts behind the language, but instead offers a reformulation of what the student said.
B) Peer correction
Peer correction refers to situations where students help each other identify and correct mistakes in their language use. This option is incorrect as the teacher, not the students, is providing the correction through recasting, making it a teacher-led intervention rather than a peer interaction.
C) Self correction
Self correction occurs when a student recognizes and corrects their own mistakes independently. This choice does not apply here, as the teacher is the one reformulating the incorrect language, rather than prompting the student to self-correct.
D) Recasting
Recasting is the act of restating a student's error in a grammatically correct form without explicitly pointing out the mistake. This option is correct because the teacher's response exemplifies recasting, as it serves to model the correct usage for the student.
Conclusion
The correct answer is recasting, as it highlights the teacher's role in modeling correct language use in response to a student's error. Other options, such as metalinguistic feedback, peer correction, and self correction, do not accurately describe the teacher's action in this context, which focuses on providing an implicit correction through reformulation.
