Classification of skills

Welcome to Skill Acquisition!

In this first chapter of the Skill Acquisition section, we are going to look at how we group and define different sporting skills. You might wonder, "Why do we need to classify skills?" Well, if you’re a coach, knowing the type of skill you are teaching helps you decide the best way to practice it.

Don't worry if this seems like a lot of categories at first—by the end of these notes, you'll see that most of it is just common sense applied to sport!

The Big Idea: The Continuum

Before we dive into the specific categories, you need to understand one key concept: the Continuum.

In PE, we don't usually say a skill is "definitely X" or "definitely Y." Instead, we place them on a sliding scale (a continuum).

Analogy: Think of a light switch versus a dimmer switch. A light switch is either ON or OFF. A continuum is like a dimmer switch—a skill can be a little bit simple, or very simple, or somewhere in the middle!

Quick Review: A continuum is a line with two extremes at either end. We place skills along this line based on their characteristics.

1. The Difficulty Continuum (Simple vs. Complex)

This is all about how much "brain power" and "movement pieces" a skill needs.

Simple Skills: These involve very little information processing and have few decisions to make. They usually have very few "sub-routines" (parts of the movement).
Example: A straight sprint start or a chest pass in netball.

Complex Skills: These require high levels of concentration, lots of information processing, and many sub-routines that must be timed perfectly.
Example: A somersault in gymnastics or a slip catch in cricket.

Key Takeaway: If you can do it without thinking much, it’s probably Simple. If it takes years of practice and intense focus, it’s Complex.

2. The Environmental Continuum (Open vs. Closed)

This looks at how much the world around you (opponents, wind, teammates) affects the skill.

Open Skills: These are heavily affected by the environment. They are unpredictable. You have to adapt your movements constantly because things around you are changing.
Example: A pass in football (you have to look at where defenders are and how fast your teammate is running).

Closed Skills: These are NOT affected by the environment. The situation is predictable and stable. You try to perform the skill the exact same way every time.
Example: A free throw in basketball or a serve in squash.

Did you know? Most "Open" skills are also "Externally Paced" because you have to react to what's happening!

3. The Pacing Continuum (Self-Paced vs. Externally Paced)

This is all about timing. Who controls when the skill starts and how fast it goes?

Self-Paced Skills: The performer (you!) decides when to start the movement and controls the speed/rate of the action.
Example: A tennis serve or a penalty kick.

Externally Paced Skills: The environment (usually an opponent or a starter pistol) decides when the skill starts and how fast it happens.
Example: Receiving a badminton serve or reacting to a sprint start gun.

Common Mistake: Students often confuse "Open/Closed" with "Pacing." Just remember: Environment = Open/Closed, while Timing/Control = Pacing.

4. The Muscular Involvement Continuum (Gross vs. Fine)

This looks at the size of the muscles being used.

Gross Skills: These involve large muscle groups and big movements. They often require power, strength, and stamina.
Example: A rugby tackle, a shot put, or a long jump.

Fine Skills: These involve small muscle groups and very precise movements. They are all about accuracy and hand-eye coordination.
Example: A putt in golf, throwing a dart, or a finger-spin in cricket.

Memory Aid: Gross = Giant movements. Fine = Fingertip control.

5. The Continuity Continuum (Discrete, Serial, Continuous)

This looks at where a skill starts and ends. This one has three points on the line!

Discrete Skills: Have a very clear beginning and a clear end. It's a single, short movement.
Example: A golf swing or a kick in football.

Serial Skills: A group of discrete skills put together to make a new, more complex movement.
Example: A triple jump (hop, then step, then jump) or a gymnastics floor routine.

Continuous Skills: Have no clear beginning or end. The end of one cycle is the start of the next. The movement just keeps going.
Example: Cycling, swimming, or running.

Quick Review:
- Discrete: One and done.
- Serial: A sequence of "ones."
- Continuous: Keeps on looping.

6. The Organisation Continuum (Low vs. High)

This is often the trickiest one, but here is the secret: It’s about whether you can break the skill into parts.

Low Organisation Skills: These can be easily broken down into separate parts or "sub-routines." You can practice just one part of the skill on its own.
Example: A swimming stroke (you can practice just the leg kick with a float).

High Organisation Skills: These are very difficult to break into parts because the sub-routines are closely linked together. If you try to take it apart, it loses its "flow."
Example: A golf swing or a somersault.

Key Takeaway: If it's "choppy" and has clear stages, it's Low organisation. If it's one "fluid" motion, it's High organisation.

Summary Checklist: Can you justify these?

To succeed in your exam, you must be able to pick a skill and justify why you put it on a continuum. Use the phrases below to help you:

- "This is a Complex skill because it has many sub-routines..."
- "This is an Open skill because the performer must adapt to the opponents..."
- "This is a Fine skill because it uses small muscle groups for accuracy..."

Don't worry if this seems tricky at first! The more sports examples you look at, the easier it becomes to "see" where they sit on the scales.
