Everyone who's ever been through the education system can recall at least one "problem child." There's sure to always be one student that oversteps being the well-meaning class clown and just wreaks havoc.
Children with multiple, repetitive behavioral issues are often reacting to a specific cause. Sometimes, it's as simple as being bored or wanting attention, no matter if it's positive or negative. Unfortunately, though, the reason can be more serious or complex. Children who feel out of control at home can often try to exact control over some other area of their life, like what they do at school. Instead of allowing their teacher to guide their behavior, they will assert control of their own actions here, regardless of consequences.
