This document discusses behaviour for learning and why students may misbehave. It provides several possible reasons for misbehaviour, including that students may not know what to do, how to do it, or why they should do a task. It also notes that there may not be consequences for misbehaviour or relevant feedback. Additionally, the document discusses adolescent brain development from ages 11-25, noting that the prefrontal cortex, which controls risk and logic, shrinks during this time. This leads teenagers to be impulsive, love risk-taking, and be ruled by emotions over logic.
