As students work on a long-term project, the teacher encourages them to pause periodically to reflect on what they understand and what they still need to learn. Which instructional strategy does this represent?

Dual coding is a learning strategy that combines verbal and visual information to enhance comprehension and memory retention. While it is effective for understanding complex information, it does not specifically involve self-reflection or assessment of one's own learning, which is central to metacognitive strategies.

Inquiry-based learning emphasizes student engagement through questioning and exploration of topics. Although it encourages active learning, it does not inherently include the reflective pauses that characterize metacognitive strategies. Inquiry-based learning focuses more on exploration than on self-assessment of understanding.

Concept mapping is a visual representation of knowledge that helps organize and structure information. While it can aid learning, it does not necessarily involve the reflective process that metacognitive strategies promote. Concept mapping is more about organizing knowledge rather than assessing one's understanding and learning needs.
