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

Semi-final

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
