Learning Task Design for Science KLA
Chow Kai Yin
Maryknoll Fathers’ School
Example: Go Up, Stay High (GUSH)Science Design Project
• Design a flight device and a launcher
• Judge by the time that the flight device stays in air
• Restrictions:– height not exceeding 5 m– maximum mass of flight device is 0.3 kg– no chemical or electrical device
Stages
1. Preliminary design and preparation
6 weeks • KF (discussion)
2. Prototype production and trial flights
2 weeks • Making the device• KF (discussion)• Semi-final contest
3. Modifying and testing of the product
2 weeks • Refining the device• KF (discussion)• Final contest
Problem of the week for KF discussion
Week 1 Launching mechanisms and launching principles
Week 2 What determines the time taken for an object to reach the top of its flight?
What determines the time for an object to fall to the ground?
Week 3 How can one ensure the object will fall back to the same location
Week 4 Design rocket and launcher to maximize the height
Week 5 Design features of the rocket to maximize the fall time
Week 6 Fabricate the model during the Easter holiday

Rubrics: Technical Design
Characteristics of project (1)
• Variety of activities– Classroom discussion– Knowledge Forum– Hands-on experience– Indoors and outdoors
Characteristics of project (2)
• Progressive stages– Talk > write and draw > work things out– Trial > adjustment > trial– In-school > inter-school– Semi-final > final
Characteristics of project (3)
• Knowledge advancement– “Build on”
• Build one’s knowledge on– Own idea– Others’ ideas– Facts and existing knowledge from references– Experience/experiments (Investigation)
– Developing higher order thinking– Applying generic skills
Characteristics of project (4)
• Collaboration– Peer cooperation– Peer assessment
• Polling on awards: knowledge advancement, explanation, advice, etc
Characteristics of project (5)
• Appropriate time span– March to May (3 months)– Time to nourish students’ interest and in-
depth participation– Possible stages of events
Room for improvement
• Clear objectives
• Rubrics
• Progressive stages
• More feedback to students
