Effective and ineffective rotary

Effective
The core supplies the strength and functional tension to the inside half of the body to facilitate the steering activity of the legs.

• Tension to builds up and is released into the new turn
• Quiet upper body
• The skier’s legs turn underneath a strong/stable torso to help guide the skis through the turn.
• Both skis and legs turn together throughout a parallel turn with the femurs turning in the hip sockets (instead of the entire hip coming around)
• Movements are progressive, unless an aggressive move is necessary

Steering movements of the legs allow us to adjust the radius of the turn and control speed
• Shoulders don’t follow tips
• Shoulders and hips level
• The skis are tipped and turned an appropriate amount to create a smooth C-shaped arc.

During turn transitions the lower body releases then realigns with the upper body.
• Constant speed and turn shape
• Tips follow tails
• Center of mass travels a more narrow path then legs

Ski into and out of counter rather than making a strong counter movement.

Ineffective
Without proper rotary movements, control deteriorates in difficult terrain because the skier cannot use the legs properly.
• The shoulders and/or torso initiate the turning of the skis.
• One ski stems or steps to begin the turn.
• The skis pivot or skid throughout the turn, creating a Z-shaped turn.
• The skis turn too quickly, causing over-turning, or do not turn fast enough, causing under-turning.

VAK - Visual, Auditory, Kinesthetic

Visual learners These students learn best by watching and imitating others. The following guidelines are helpful when teaching visual learners. • Ski well-executed demonstrations that illustrate the point. Be careful not to exaggerate and destroy the picture of good skiing. • Target the students’ attention to a certain part of your body or to particular movements.

Learning Styles – Doers, Feelers, Thinkers, Watchers

A learning style is the way a person’s sensory, perceptual, memorial, decision-making, and feedback mechanisms operate. Or more simply, the preferred technique to approach learning. Some students have a dominant style and others are comfortable in more than one. PSIA references different theories on learning styles, this is a classic one. Doers Values active experimentation Pragmatic, practical, functional Good problem solvers, work well with others Constantly active, doesn’t like being idle and gets frustrated with too much talking Learn by experimenting, trial and error Instructor should provide experiences that will guide the child Experiential learning is an effective method for all students

Sarah’s Big Binder of Ski Teaching Geekery (and more!) (Updated/edited as of October, 2015)

UPDATE: October, 2015: This has been updated with new links, programs, and information. Please let us know if you have other references, we promise to update again before 2020! - Kerry (Diva2) Last year when I was preparing for my L3 Part 1 Skiing exam, the Dev Team Diva turned me on to these great task descriptions developed by Bob Barnes for the PSIA Rocky Mountain Division (the Pocket Summaries listed under "Skiing" below). (Kerry's edit: Those pocket summaries are not on the PSIA-RM site anymore. But I think what you're looking for is in the Skiing IDP linked below.) In my search for them online, I discovered lots of other valuable ski teaching resources tucked away on various PSIA divisional Web sites. So I printed them out, organized them into categories, and stuck them in a binder. The binder became an invaluable resource in discussions with my good friend and ski coach as I helped him to prepare for his Dev Team tryout and he coached me to success in my ski
