Understanding how humans grow and change is really important for Year 9 psychology students. Here are a few reasons why:

1. Building Knowledge:

   • The work of Piaget, Erikson, and Vygotsky gives us ways to understand how people behave.
   • Piaget talked about four stages of thinking that kids go through, which can help teachers know how to teach better.

2. Real-Life Connections:

   • Knowing about these development stages helps us understand how our friends act.
   • For instance, Erikson suggested that kids ages 12 to 18 often struggle with figuring out who they are. This can affect how they get along with others.

3. Important Facts:

   • Research shows that 60% of teens deal with big challenges when trying to form their identities during this time.
   • This shows how understanding these theories can help us support each other better.

4. Developing Skills:

   • Learning these ideas improves our thinking skills and helps us be more understanding of our peers, which are key skills for doing well in school and life.

By exploring human development, students can learn more about themselves and their friends. This leads to better relationships and stronger emotional understanding.
