Interactive Demonstration / Experiment

#plenary #skills-practice

Why:
Interactive demonstrations can be used in lectures to demonstrate the application of a concept, a skill, or to act out a process. The exercise should not be passive; you should plan and structure your demonstration to incorporate opportunities for students to reflect and analyse the process.

How:

  • Introduce the goal and description of the demonstration.
  • Have students #think-pair-share (see above) to discuss what they predict may happen, or to analyse the situation at hand (“pre-demonstration” state or situation).
  • Conduct the demonstration.
  • Students discuss and analyse the outcome (either in pairs/small groups, or as a whole class), based on their initial predictions/interpretations.
  • Advantages of interactive demonstrations include novel visualizations of the material and allowing students to probe their own understanding by asking if they can predict the outcome of the demo. They are also a venue for providing applications of ideas or concepts.
