Identify a common instructional strategy for teaching main ideas.

The "topic and details" strategy is an effective instructional approach for teaching students how to identify main ideas. This method emphasizes the relationship between a general concept (the topic) and the specific supporting information (the details) that elaborates on that concept. By focusing on this strategy, students learn to discern the central idea of a text while recognizing the details that reinforce or expand upon it.

This strategy equips learners with the skills to identify the overarching theme of a passage and distinguish it from supplementary information, enabling a clearer understanding of the material. By practicing with various texts where they identify the topic first and then pinpoint the relevant details that support it, students can develop a strong grasp of how to extract main ideas effectively.

In contrast, the other options represent different strategies that may not specifically target the identification of main ideas. For example, the "summary and conclusion" strategy focuses more on synthesizing information rather than pinpointing main ideas directly. "Visualization" aids comprehension through mental imagery, and "recall and discuss" emphasizes memory and verbalization, which may not be as directly aligned with explicitly identifying main ideas. This makes the "topic and details" strategy the most pertinent choice for teaching this particular skill.
