Writing samples:Biological
The following section includes annotated samples of responses to exam questions - as well as strategies for answering questions based on the command terms. The responses are not from the IB. They are created specifically for the site.
There is no definitive list of questions for this curriculum - so the list of potential questions below is not exhaustive. However, most of the questions will fall within the list that has been provided below. The questions are grouped by topic and include both SAQ and ERQ (essay) questions.
SAQs may be asked using the command terms explain, describe or outline. In the following sections, all questions will be stated using "explain" to simplify this page.
ERQs may be asked using the command terms discuss, evaluate, contrast or "to what extent" as appropriate. All examples below will use the command term "discuss" to simplify this page.
For the ERQ responses, students should include two or more pieces of research. Only one piece of research should be used for responses to SAQs.
SAQs
- Explain the use of one research method in one study using the biological approach to understanding human behaviour.
- Explain the use of one research method in one study of the brain and behaviour.
- Explain the use of one research method in one study of hormones or pheromones and behaviour.
- Explain the use of one research method in one study of genetics and behaviour.
- Explain one ethical consideration relevant to one study using a biological approach to understanding human behaviour.
- Explain one ethical consideration relevant to one study of the brain and behaviour.
- Explain one ethical consideration relevant to one study of hormones or pheromones and behaviour.
- Explain one ethical consideration relevant to one study of genetics and behaviour.
ERQs
- Discuss the use of one or more research methods...
- Discuss ethical considerations .....
SAQs
- Explain one technique used to study the brain in relation to behaviour.
