Refereeing Non-Invasion Sports Games
Refereeing in selected Non-Invasion Sports Games:
Just as with Invasion Sports Games, the useful motto applies: "Play, Study, Referee." First, experience the game as a player, then understand the rules and their purpose, and finally, practice refereeing in the field. In non-invasion games, this significantly improves your ability to "read the flight of the ball," hear and see a double bounce, perceive the pace of the rally, and the "cleanliness" of the contact/hit.
Therefore, in non-invasion SGs, we focus primarily on judging the flight and landing of the ball and technical errors in playing the ball, rather than physical contact between opponents (as is the case in invasion SGs).
The goal of this stage is to get to know the game "from the inside"—practically (i.e., by playing), from the player's perspective being able to serve, receive, sustain a rally, read the rebound, perceive the net, the lines, and the "speed" of the surface. In Net/Wall Games (tennis, badminton, table tennis, volleyball), this develops the perception of the ball landing in-bounds or out-of-bounds, and a feeling for the basic principles of the game. In Striking/Fielding Games (softball, baseball, brännball), you gain a feel for pitching—i.e., a good pitch (strike) / bad pitch (ball) (in school variants), the correct hit, running the bases, and the batting order.
Study the current official rules of the given SG (or their school modifications for teaching, if they are official—e.g., slowpitch softball), focusing on the purpose of the rule and its didactic application in school PE. Conversely, mechanical memorization of court dimensions, ball size, etc., is usually not necessary.
When studying (ideally with a mentor or experienced classmate), make an excerpt/summary with regard to:
● The purpose of the rule (why it exists)
● The consequence of a violation (e.g., a service fault in volleyball = the consequence is a point for the opponent and their right to serve)
● Signaling (what and how I show/announce)
● Ambiguities (what I need clarification on)
This summary and its application to practical skill development on the court will subsequently help you in the transfer between non-invasion games, as many principles are transferable (e.g., "a ball that touches the line is good" in tennis/table tennis).
The third stage is primarily practical: it is based on the practice of observation, decision-making, and signaling in real-life situations. We recommend:
● Model situations on the court/field (short drills with clear instructions: a series of serves landing in/out of bounds, a double hit in footnet, etc.).
● Imitation training of signaling (mirror work, video feedback, mentor instruction).
● Qualitative and notational analysis of the game focused on refereeing activities (number of service faults, percentage of correctly judged in-bounds spikes, frequency of net touches, etc.).
In non-invasion games, it pays to train according to the sequence: "eye–whistle–signal". For example, clearly stopping a footnet rally when the ball lands out-of-bounds by whistling, calling "out," and signaling with the hands.
