Sampling techniques

From OER in Education

Lesson idea. A comprehension and discussion activity based on four different organisms: the butterfly, the oak, the whale and the zebra.

Teaching approach. This lesson offers students an opportunity to use their existing knowledge to analyse a ‘real scientific publication’ and its language(ta) and link this to scientific method(ta).

  • They use study skills(topic) to skim read, make sense of complex language, and use visualisation(ta) to select relevant information
  • They engage in collaborative(tool) group work(ta) using reasoning(ta) and skills in peer assessment(ta)
  • They engage in dialogue(ta) and questioning(ta) to explore ideas together
  • They also think about how to present information using ICT(i) tools)

  • Explaining the advantages of a special sampling technique when compared with other methods.
  • Communicating the results and conclusion of the supplied articles on sampling populations.
Format / structure

Each organism has 4 documents where N represents: B (Butterfly), O (Oak), W (Whale) or Z (Zebra)
N1 – Leading questions
N2 – Differentiated material
N3 – a word document copy of the web-based article if no ICT is available or if the article is not available online
N4 – a truncated word document of the original article to be used as differentiated material. The text contains the parts relevant to answer the leading questions from the original article
