Which of the following is an effective strategy for teaching third graders key concepts in expository texts?

Using semantic feature analysis is an effective strategy for teaching third graders key concepts in expository texts because it helps students understand and organize information by focusing on the relationships between different concepts. This method encourages students to think critically about the material by identifying the features that define each concept and how those features compare across various subjects. It enhances vocabulary acquisition while also promoting comprehension of the text's main ideas and supporting details.

This strategy is particularly beneficial for younger learners who may struggle with the abstract nature of expository texts, as it provides a visual and structured approach to analyzing information. By actively engaging with the content in this way, students are more likely to retain and apply what they have learned.

Other strategies, such as assigning homework readings or focusing solely on vocabulary, may lack the interactive and analytical components that make semantic feature analysis particularly effective. Furthermore, conducting lectures may not facilitate the same level of engagement or critical thinking among third graders, who often benefit more from collaborative and hands-on learning experiences.
