This lesson is principally conducted outside using a slackline. There is information on how to use a slackline to teach self-efficacy here.
Set the session up by showing the introduction to the documentary on legendary slackliner Dean Potter here (up until 1 minute 30 is enough), or this video of Leo Houlding slacklining the Lost Arrow Spire (some bad language). Ask students if any of them would do what he does: what are their reasons? You could let them know that Dean Potter died whilst base-jumping in 2015: does that change their minds? The story of his death is here.
Have a look at the explanation of self-efficacy here. Go through the different elements needed to build up our confidence that we can accomplish something, particularly something either new or challenging.
Take the students out and slackline with them. Pause regularly to discuss how as a group they are helping to build each other’s self-efficacy and relate this back to how they operate as a class in other learning environments.
Prep: ask pupils to use what they have learned so far about avoiding thinking traps and self-efficacy to try to build their self-efficacy with something they find difficult or challenging and write about their experiences.
