At the start of every year I take my students through a unit on athletics, this year it is years 7, 8 and 9. Each year I teach the different events and associated skills and by the end students have recorded times, distances and heights for all events. Along with other observational data I have used those times, distances and heights to generate a grade. This year I have not been getting the students to measure any results. We started last week with their focus purely on developing technique.
