The idea of a “prebrief” is to introduce an activity or pique the interest of the class before launching into an experience.
Here are some ideas for effective prebriefs:
Ask the students to speculate about what they are about to discover.
For example, if students are going to tour the building for the first time, ask they what they expect to see, what they are wondering about, etc.
Start with a broad example or story. Ask students questions to get them thinking about the topic you are about to explore.
Show a funny or compelling media clip or play a song that is related to your topic. Ask the students to unpack what you have shown them in relation to the activity you are about to do.
Design a surprising way to introduce the activity. Put the instructions for the activity in an envelope. Create a scavenger hunt. Create some mystery around what the students are about to do.
