Students work in groups to answer five questions about vocabulary from the previous unit. Then, they exchange questions with another group and try to answer the questions. This is an example of:

The correct option is Peer assessment.

Explanation:

Peer assessment occurs when students evaluate or provide feedback on each other's work. In this scenario, students work in groups to create questions and then exchange them with another group to answer and evaluate. Because the evaluation and interaction happen directly between classmates (peers) rather than through self-reflection or teacher evaluation alone, this activity is a classic example of peer assessment.

Let's briefly examine why the other options do not fit:

• Self-assessment: Refers to a process where an individual student reflects on and evaluates their own performance or work.
• Feedback: A general term for information given to a learner about their performance, but here the specific activity mechanism being described is group-to-group peer assessment.
• Reading assessment: Focuses specifically on measuring reading comprehension and skills, whereas this activity focuses on collaborative vocabulary application and peer interaction.
