In a teacher-led discussion, what skill would the group activity primarily promote?

The focus of a teacher-led discussion often revolves around enhancing students' understanding of language and meaning, which is why the chosen answer is appropriate. In this context, using semantic and syntactic clues to identify meaning involves engaging students in critical thinking about the text or concepts being discussed. This skill allows students to draw on their knowledge of word meanings (semantics) and sentence structure (syntax) to derive understanding from what they read or hear.

Participating in discussions encourages students to think deeply about language, as they must interpret, analyze, and construct arguments based on the material presented. This process helps them become more adept at using language effectively for comprehension and communication, which is fundamental in their reading development.

The other options, such as improving handwriting, memorizing definitions, or practicing spelling rules, do not intersect as directly with the skills honed during a discussion. These activities focus more on mechanics or rote learning rather than the interactive and analytical nature of understanding language through discussion. Thus, the emphasis on using semantic and syntactic clues is what distinguishes the primary skill being promoted in a teacher-led discussion.
