The Science Rifi



Controlled assessments
Introduction: What is a controlled assessment?

A controlled assessment is a new form of internal assessment that replaces coursework in the UK.

What are you expected to do?
  • Plan practical ways to answer scientific questions and test hypotheses.
  • Devise appropriate methods for the collection of numerical and other data.
  • Assess and manage risks when carrying out practical work.
  • Collect, process, analyse and interpret primary and secondary data including the use of appropriate technology.
  • Draw evidence-based conclusions.
  • Evaluate methods of data collection and the quality of the resulting data.

In addition students studying additional or separate science must be able to devise their own hypothesis.

Outline of the ISA process

Step 1
-Teacher chooses assessment task from a few provided by AQA
-Teacher explains to students the nature of the problem to be investigated – This is a hypothesis supplied by AQA*

Step 2
Students research:
- 2 ways to carry out the investigation- record notes on AQA-supplied candidate notes sheet
-The context around the investigation
-Risk assessment –health and safety issues around the investigation
On the candidate notes sheet, students will record-

Step 3
Students draw a blank table of results- see the Recording and analysing data page

Step 4 Test Section 1 (20 marks)
Students complete a written 45 minute test with questions about:

  • the equipment that you plan to use
  • how you will use the equipment
  • the measurements that you are going to make
  • how you will make it a fair test
  • a risk assessment

Step 5 Part 2 of the ISA
-Carry out the practical using your chosen method or an AQA supplied method
-Record results on a table
-Draw suitable chart (bar chart, line graph as appropriate) -for guidelenes, see the Recording and Analysing data page

Step 6 Test Part 2
-50 minute test about results, conclusion and evaluation, will also relate investigation to context

Secondary data is also supplied for this question, so you need to be able to relate it to the investigation and also compare it with the primary data that you collected.
