2. All About Adolescence
 Adolescence describes the teenage years between 13 and 19
and can be considered the transitional stage from
childhood to adulthood. However, the physical and
psychological changes that occur in adolescence can start
earlier, during the preteen or "tween" years (ages 9-12).
Adolescence can be a time of both disorientation and
discovery. The transitional period can bring up issues of
independence and self-identity. Sometimes adolescents
may be experimenting with drugs and alcohol or sexuality.
During this time, peer groups and external appearance
tend to increase in importance.

3. Theories of Education:
 Constructivism is a philosophy of learning founded
on the premise that, by reflecting on our
experiences, we construct our own understanding of
the world we live in. Each of us generates our own
"rules" and "mental models," which we use to make
sense of our experiences. Learning, therefore, is simply
the process of adjusting our mental models to
accommodate new experiences.
