This task is based on a City & Guilds sample Paper 1 question, and involves modelling the level of a prescribed drug (with a half-life of between 1 and 4 hours) within a patient. It was adapted by the SouthWest and West Early Adopters, to provide a specimen problem-solving activity. Task-specific assessment grids were then designed by this group, intended for peer assessment.

Overview of task

This task is based on a City & Guilds sample Paper 1 question, and involves modelling the level of a prescribed drug (with a half-life of between 1 and 4 hours) within a patient. It was adapted by the SouthWest and West Early Adopters, to provide a specimen problem-solving activity. Task-specific assessment grids were then designed by this group, intended for peer assessment.

+
Prior knowledge

An appreciation of ‘half-life’. The exponential function could be introduced (not essential).

+
Relevance to Core Maths qualifications

  • AQA
  • C&G
  • Eduqas
  • Pearson / Edexcel
  • OCR

+
Suggested approaches

This task could as easily lend it self to small group work as to individual work, according to students’ preferences.

+
Resources/documentation

In addition to this teacher guidance there are:

  • Youtube (a ‘funny’ clip to use at start): House MD Clinic patient inhaler fail: http://youtu.be/Qg78NzjLcrQ
  • Handout (Cormathzadine) with relevant data for students
  • Specific assessment grid – can be used for peer assessment
  • Examples of student work to trial peer assessment

+
Relevant digital technologies

Spreadsheet for modelling/graphing software/calculator

+
Possible extensions

The exponential function of decay could be introduced, as illustrated in the City & Guilds sample pre-release material. See the Core Maths Masters Subject Support, Strand: Graphs; Units 4 and 5 for further extensions. For a similar project, see the Nuffield FSMQ resources: http://www.nuffieldfoundation.org/fsmqs/level-3-algebra#Maximum%20and%20minimum%20problems
