  • Exam-style question
Why does Amir think that?: Amir, 16, lives in a coastal town and supports a new sea wall. To explain his view, trace what went in and what came out.

An environmental value system (EVS) is a model of exactly that: the inputs that shape a perspective, and the outputs that come from it.

Inputs

  • What shapes the view

Perspective

  • How Amir sees the issue

Outputs

  • What he judges, chooses and does

Inputs are everything that feeds into a perspective. Amir's include:

Media

  • Videos of storms flooding other towns.

Education

  • A geography lesson on rising sea levels.

Worldviews

  • His family's belief that the town must be protected.
Other inputs: Family, friends, religion and lived experience are inputs too. Name the input, then say what it adds.

Outputs are what comes out of a perspective. Amir's:

1

Judgement

The town is at real risk from the sea.

2

Position

He supports the sea wall.

3

Choice

He cycles to school instead of being driven.

4

Action

He speaks for the wall at a council meeting.

Change an input, change the output: If Amir learned the wall would destroy the beach where he fishes, his outputs could change.
How this comes up: A Paper 2 part (a) [4], or a short Paper 1 part asking you to pick inputs and outputs from a source.
IB-style questionOutline[4 marks]

Outline the inputs and outputs of the environmental value system of a named person or group.

The trap: Listing inputs only. The model has two sides, so give outputs too.
