•Store in javelin rack at collection point; never leave lying on ground
Alternative: Turbo javelins, foam javelins, or vortex howlers for students with less upper body strength
Fully charged, apps open and ready, protective cases on
Alternative: Mobile phones with slow-motion video capability, video cameras on tripods
Create clear throwing lanes 5m wide, mark safe collection zones
Alternative: Marker discs, rope boundaries, painted lines on field
Used for measuring throws in game application phase
Alternative: Trundle wheels, pre-marked distance markers on ground
Essential for safety - all students must stop on whistle
Alternative: Loud voice, air horn for large outdoor spaces
Include student names, space for 10 throws, valid/invalid checkbox
Alternative: Clipboards with blank paper, digital recording on tablets
Test video plays before lesson, have backup video ready
Alternative: YouTube technique videos, athletics coaching resources, pre-recorded demonstration
Position near teaching area, students aware of location
Alternative: School nurse on call, designated first aider present
How you hold the javelin - either knuckle grip (javelin rests on palm, secured by index finger and thumb) or fork grip (javelin held between index and middle fingers)
The moment the javelin leaves your hand - should be high (above shoulder height) with elbow leading and wrist flicking through
A legal throw where the metal tip of the javelin lands first, creating a mark in the ground
Standing sideways to the throwing direction with non-throwing shoulder pointing at target
A stepping technique where the back leg crosses in front of the front leg to generate momentum before the throw
Keeping the throwing elbow at or above shoulder height during the throw to achieve proper trajectory
The path the javelin takes through the air - good flight shows a smooth arc with the tip pointing forward throughout
The pointed metal end of the javelin that must land first for a valid throw
The continuation of throwing motion after release, with arm extending toward target and body weight transferring forward
Understanding where pupils are coming from and where they're going
Technical vocabulary development and accurate usage. Giving clear verbal instructions to partner. Listening skills during video analysis feedback. Articulating self-assessment and targets. Writing feedback comments on peer performance.
Measuring distances to nearest 10cm using tape measures. Calculating average distance from three throws. Analysing data to identify improvement trends. Understanding angles of trajectory. Calculating valid throw percentages. Recording and presenting data on graphs. Using mathematical language: greater than, less than, average, percentage.
Forces in javelin throwing - push/pull forces, gravity, air resistance affecting flight. Kinetic energy transfer from body to javelin. Trajectory and projectile motion. Levers in the body - arm as lever system, fulcrum at shoulder. Muscles used in throwing - deltoids, triceps, core muscles, latissimus dorsi. Energy systems - anaerobic energy for powerful throws.
Using iPad technology for video recording. Operating slow-motion video apps effectively. Analysing digital footage to identify technique points. Understanding frame-by-frame analysis. Digital data recording and organisation.
Using directional language - throw toward north, south, east, west. Spatial awareness of throwing zones and landing areas. Mapping the throwing area showing measurements. Understanding how wind direction affects javelin flight (geography connection to weather).
Resilience - persisting when cross-over technique difficult, learning from failed attempts. Teamwork - working effectively with partner during video analysis. Communication skills - giving and receiving feedback constructively. Setting personal targets for improvement. Celebrating others' success. Managing frustration and emotions when technique difficult. Supporting peers with encouragement.
During whole-class instruction: position at edge of student formation where all can see demonstrations. During skill practice: position at end of throwing line with side-view of all students. During partner work: circulate continuously among pairs, stopping to observe individual throws. During video analysis: move between pairs to facilitate feedback discussions. NEVER stand in potential landing zones.
Watch for: 1) Safety compliance - correct carrying, same direction throwing, whistle response. 2) Technique fundamentals - grip security, high elbow position, javelin tip angle, weight transfer. 3) Valid throw percentage - tip landing first consistently. 4) Footwork coordination in cross-over attempts. 5) Engagement and challenge level - students appropriately challenged not bored or overwhelmed. 6) Partnership quality - communication, support, equal participation.
Intervene immediately if: any unsafe behaviour (horizontal carrying, throwing without signal, entering landing zone). Intervene quickly if: technique significantly incorrect (elbow very low, dangerous release angle). Intervene supportively if: student struggling with coordination (offer simplified version). Intervene encouragingly if: student showing frustration or giving up (reframe challenge, celebrate small progress). Do NOT intervene if: minor technique imperfections being self-corrected, productive struggle occurring.
Demonstrate: all new techniques in slow motion first, then full speed. Show from multiple angles - front, side, back - as different students see better from different viewpoints. Exaggerate key elements (very high elbow, very tip down angle) so they're clearly visible from distance. Use competent student demonstrators when possible to show technique is achievable by peers. Demonstrate common mistakes then correct version to show contrast. Narrate during demonstration: 'Watch my elbow - see how high it is? This is the most important part.' Keep demonstrations brief (30-60 seconds) to maintain engagement.
Minimum 40m x 30m outdoor space (athletics field or large playground). Clear run-off area of at least 15m beyond maximum throwing distance. No boundaries, trees, buildings, or hard surfaces within 10m of throwing zones.
Grass surface preferred for javelin landing. Check surface is dry (not after heavy rain causing slippery conditions). Inspect for holes, uneven ground, or hidden obstacles. Remove any stones, sticks, or debris from throwing and landing areas before lesson begins.
Two sharp whistle blasts: all activity stops immediately, all students freeze. Assess situation: if student injured, send responsible student to fetch first aider/school office. Administer first aid if trained and appropriate. If javelin strike: assess injury severity, do NOT remove javelin if embedded, keep student still, call for immediate medical assistance. For minor injuries: ice pack, rest, elevate, monitor. Complete accident report form. Contact parents if injury requires attention beyond basic first aid. Preserve equipment involved for inspection.
