This worksheet summarizes the evolution of different techniques in high jump. It outlines the main phases of jumping events - the starting run, take-off, flight, and landing. It then provides a table analyzing the student's attempts at different high jump techniques - frontal jump, simple scissors, ventral jump, and dorsal/Fosbury flop. The student was unable to clear 90cm on their first two attempts at frontal jump but cleared it on the third try. They failed on their first two attempts at simple scissors at 1m but cleared 80cm on the third try.
