Which activity involves discussing readings through shared observations in small groups?

The activity that involves discussing readings through shared observations in small groups is best identified as Literature Circles. Literature Circles are structured forms of small-group discussions where students engage with a text collaboratively. In these circles, each participant has a specific role, and they share their insights, observations, and analyses of the readings. This approach fosters a deeper understanding of the text as students learn from each other's perspectives and interpretations.

While "Say Something" encourages students to make verbal contributions during reading (typically by pausing and sharing thoughts in response to the text), it lacks the specific structure of small group discussions characteristic of Literature Circles. This activity is more focused on individual response rather than collaborative dialogue.

Paideia Seminars also emphasize discussion but primarily focus on whole-class discussions driven by open-ended questions, and the format is less about small groups specifically sharing observations.

Cornel Notes Method refers to a specific note-taking strategy that helps students summarize and organize their reading, but it does not inherently involve group discussions or shared observations.

Thus, Literature Circles is the most appropriate choice for the activity described.
