Command Terms

The VCAA do not provide a list of explicit definitions for the command terms used in VCE Biology (because that would be too useful)

  • However, most terms are associated with uniform expectations and hence their meaning can be assumed as per the following list
  • The different objectives reflect the level of depth required in a response (more depth will likely involve more marks)


Objective 1

These terms require a student to demonstrate knowledge and understanding of facts, concepts and terminology

  • Define:  Give the precise meaning of a word, phrase or physical quantity
  • Draw:  Represent by means of pencil lines
  • Label:  Add labels to a diagram
  • List:  Give a sequence of names or other brief answers with no explanation
  • Measure:  Find a value for a quantity
  • State:  Give a specific name, value or other brief answer without explanation or calculation

 

Objective 2

These terms require a student to apply methods of communicating scientific information 

  • Annotate:  Add brief notes to a diagram or graph
  • Apply:  Use an idea, equation, principle, theory or law in a new situation
  • Calculate:  Find a numerical answer showing the relevant stages in the working (unless instructed not to do so)
  • Describe:  Give a detailed account
  • Distinguish:  Give the differences between two or more different items
  • Estimate:  Find an approximate value for an unknown quantity
  • Identify:  Find an answer from a given number of possibilities
  • Outline:  Give a brief account or summary


Objective 3

These terms require a student to formulate, analyse and evaluate hypotheses, methodologies, data and scientific explanations

  • Analyse:  Interpret data to reach conclusions 
  • Comment:  Give a judgment based on a given statement or result of a calculation
  • Compare:  Give an account of similarities and differences between two (or more) items, referring to both (all) of them throughout
  • Construct:  Represent or develop in graphical form
  • Deduce:  Reach a conclusion from the information given
  • Derive:  Manipulate a mathematical relationship(s) to give a new equation or relationship
  • Design:  Produce a plan, simulation or model
  • Determine:  Find the only possible answer
  • Discuss:  Give an account including arguments for and against the relative importance of various factors, or comparisons of hypotheses
  • Evaluate:  Assess the implications and limitations
  • Explain:  Give a detailed account of causes, reasons or mechanisms
  • Predict:  Give an expected result
  • Show:  Give the steps in a calculation or derivation
  • Sketch:  Represent by means of a graph showing a line and labelled but unscaled axes but with important features clearly indicated
  • Solve:  Obtain an answer using algebraic and/or numerical methods
  • Suggest:  Propose a hypothesis or other possible answer
