more obvious and easily identifiable. One strategy for assisting observation is to give your students a task that requires them to slow down their movements, or to ski on a slope that is relatively flat.
Keep in mind that slower skiing, while helpful for your eye, may not be very exciting for students. Use these observation tactics carefully to challenge, but not bore your students.
WHOLE VS. PART
How you choose to frame the picture also affects your overall observation. You may choose to look at the whole skier first, before zooming in on specific body parts. You might focus only on the ski actions. Each method provides different, yet valuable information you can apply to your analysis.
Studies have shown that less experienced observers evaluate more accurately when focused on a particular part of a performance. Tis may include keen observation of a specific part of the body or a particular part of the turn. More experienced observers have equal success with either approach, but tend to favor observing a whole image.
SKI PERFORMANCE
Observe how skis act on snow to see how much they are turned (rotational control), tipped (edge control), and bowed (pressure control). Notice if there appears to be a balance between skills, or if one skill dominates.
Watch the path of the skis throughout turns to observe whether speed is controlled by turn shape or through braking maneuvers, such as slipping or excessive skidding. Notice if the path of the skis creates a turn in the shape of a C, J, or Z (the C being the generally favored goal and the J and Z indicating potential turn mechanics to address).
PHOTO 6.4: In this basic parallel turn, the skis are tipped early on edge, steering occurs throughout the turn, and pressure is predominantly on the outside ski.
