CommonLit is a free service that offers a large collection of fiction and nonfiction texts paired to reading questions. You can create a classroom on CommonLit in which you can monitor your students' progress through the texts that you assign to them.
Recently, CommonLit added a new feature that they call Guided Reading Mode. When you enable Guided Reading Mode your students will see questions appear in the margin of the documents. Students have to answer those questions correctly in order for the next section of the document to appear. See the Guided Reading Mode in action in the video embedded below.
Applications for Education
CommonLit has been a favorite resource of mine for a couple of years because of the nature of the thematic questions they provide for thought and discussion. The only trouble was that if students didn't understand the assigned text they would have difficulty participating in conversation about the thematic questions. The new Guided Reading Mode should help more students understand assigned texts and participate in classroom discussions about the thematic questions accompanying assigned texts.
