Using the example of a basketball free throw, identify THREE ways it can be classified according to the characteristics of motor skills.   (3 marks)

Show Answers Only

Sample Answer

  • A basketball free throw is classified as a discrete skill because it has a clear beginning when the player receives the ball and a definite end when the ball is released toward the basket.
  • It is categorised as a closed skill as it is performed in a stable environment where conditions such as distance to the basket, basket height, and ball size remain constant.
  • The free throw is self-paced because the player controls when to release the ball, having up to 10 seconds to shoot after receiving it from the referee.

The image below shows a cricket batter facing a fast bowler.

Which skill classification would MOST accurately describe the batter's action in this scenario?

  1. Closed, self-paced, discrete
  2. Open, self-paced, continuous
  3. Closed, externally paced, serial
  4. Open, externally paced, discrete

\(D\)

Show Worked Solution
  • D is correct: The batter must adapt to the varying delivery from the bowler (open), the timing is determined by when and how the ball is bowled (externally paced), and the batting stroke has a clear beginning and end (discrete).

Other Options:

  • A is incorrect: Batting occurs in a changing environment due to variations in bowling (open, not closed) and the timing is determined by the bowler’s delivery (externally paced, not self-paced).
  • B is incorrect: Batting involves distinct actions with clear beginning and end points (discrete, not continuous).
  • C is incorrect: The environment is constantly changing based on the bowler’s delivery (open, not closed) and batting is primarily a discrete skill rather than a sequence of movements (not serial).

  • A is correct: A gymnastics floor routine primarily uses large muscle groups (gross), occurs in a stable environment (closed), the gymnast controls the timing (self-paced), and consists of discrete elements performed in sequence (serial).

Other Options:

  • B is incorrect: The environment in gymnastics floor routines is stable with consistent conditions (closed, not open).
  • C is incorrect: Gymnastics primarily uses large muscle groups (gross, not fine), the gymnast controls timing (self-paced, not externally paced), and consists of discrete elements in sequence (serial, not continuous).
  • D is incorrect: Gymnastics uses large muscle groups (gross, not fine), occurs in a stable environment (closed, not open), and the gymnast controls timing (self-paced, not externally paced).

The table shows characteristics of four different sport skills.

Sport Skill    Environment  Pacing Beginning and End
W Stable Self-determined   Clear start and finish
X Changing External factors  Ongoing with no clear endpoints  
Y Changing Self-determined  Series of connected movements
Z Stable External factors  Clear start and finish

Which sport skill would BEST exemplify classification W?

  1. Returning a serve in tennis
  2. Rugby lineout throw
  3. Free throw in basketball
  4. Freestyle swimming in a race

\(C\)

Show Worked Solution
  • C is correct: Performed in a stable environment (closed), the player controls when to shoot (self-paced), and the action has a clear beginning and end (discrete).

Other Options:

  • A is incorrect: Returning a serve is externally paced (timing determined by opponent’s serve) and occurs in a changing environment (open).
  • B is incorrect: While a lineout throw has a clear beginning and end, the environment includes opponents and timing is influenced by referee whistles (not fully self-determined).
  • D is incorrect: Freestyle swimming is a continuous skill without clear beginning and end points during execution.

The image below shows a mountain bike rider navigating a rocky downhill trail.

Based on this activity, which classification is MOST accurate for this skill?

  1. Open, externally paced, continuous
  2. Open, self-paced, continuous
  3. Closed, externally paced, serial
  4. Closed, self-paced, serial
Show Answers Only

\(A\)

Show Worked Solution
  • A is correct: Mountain biking on a rocky trail occurs in an unstable environment that requires constant adaptation (open), the timing is influenced by the terrain features (externally paced), and the riding motion consists of ongoing adjustments without clear beginning or end points (continuous).

Other Options:

  • B is incorrect: While mountain biking is open and continuous, the timing of movements is dictated by approaching terrain features rather than being fully controlled by the rider (externally paced, not self-paced).
  • C is incorrect: The environment is unstable (open, not closed), and the skill involves ongoing movements rather than a sequence of discrete skills (continuous, not serial).
  • D is incorrect: The environment is unstable (open, not closed), and the skill does not consist of discrete elements combined in sequence (continuous, not serial).

A netball player catches the ball, pivots, and passes to a teammate during a match.

Which of the following best describes this skill according to motor characteristics?

  1. Fine motor, closed, self-paced
  2. Gross motor, open, externally paced
  3. Fine motor, open, externally paced
  4. Gross motor, closed, self-paced

\(B\)

Show Worked Solution
  • B is correct: Catching, pivoting and passing involves large muscle groups (gross motor), occurs in a changing environment with defenders (open), and timing is influenced by opponents’ positions and movements (externally paced).

Other Options:

  • A is incorrect: Netball passing primarily uses large muscle groups (gross motor, not fine motor) and occurs in a changing environment (open, not closed).
  • C is incorrect: Netball passing primarily uses large muscle groups (gross motor, not fine motor).
  • D is incorrect: Netball passing occurs in a changing environment (open, not closed) and timing is influenced by game conditions (externally paced, not self-paced).
