My goal was not to just get them to predict and record, but also to remember and be able to explain 2 important technical aspects of each event. Prior to doing each event, we had a discussion about key technical points. It was important for them to know and understand these technical aspects and be able to apply them during the event itself in order to try and produce their best result possible.
They made their predictions, did the event then recorded their actual result also being sure to include an explanation of 2 technical aspects. The class went very well and upon a close look of their formative assessment sheets, most students were able to recall 2 technical aspects which demonstrates that they were being attentive and listening to expectations. Please see example student assessment below.
