Weekly interactions are posted in Google Classroom each Wednesday morning. Students will reply to their teacher's post and the teacher will reply to each student's post weekly. These are documented in MiStar and count for your student's attendance each week. The conversation loop is not closed until the teacher replies to each individual student and that reply may include a question, so make sure your student is checking back.
This example has a response from a student that is thorough, detailed and fully answers each portion of the teachers interaction post. The response mentions a core subject and is more than 3 sentences.
This example is lacking in multiple areas of the students response to the interaction. It isn't specific, doesn't fully answer all the parts of the teachers post and doesn't really give the teacher any information.
