At the elementary level any student who does not undertand the concept, or who is struggling with the concept I will pull to work with in a mall group. I might also send them with another teacher for intervention (at my school, we each work with another teacher and do intervention with their students who need it). When I see students struggling with the work, or when a student does poorly on a test I use that information to decide who I am working with in small groups. How do you do that at the secondary level? When a student fails, let´s say a math test, what would be your next step of action? Are students allowed to continue working on tests and retest? I am very curious because my daughter struggles in math and I am trying to figure out how secondary teachers, in general, help those kinds of students.
