Science Education Section2010

Aim: To enhance the integration of the

learning, teaching and assessment for quality learning

To broaden the scope of assessment in SBA

Action required: Students are required to perform a stipulated number of non-practical related tasks.

A task used should cover one or more of the curriculum content areas and one or more of the generic skills such as Creativity, Critical thinking skills, Communication skills and Problem-solving skills (3C1P).

1. Critical reading, analysis and reporting on the contribution of chemistry to the understanding of the material world

2. Designing a poster or pamphlet aimed at persuading people to follow the principles of green chemistry, or explaining the principle of a chemical cell

3. Writing a report to present the scientific knowledge and concepts acquired after a visit to an industrial plant

4. Developing a multimedia artefact to illustrate the synthesis of polymers

Example 1: critical reading, analysis and reporting on the contribution of chemistry to

the understanding of the material world

Some students wish to examine the social economical consequences of rusting / Haber process / burning fossil fuels, … etc.

Learning elements: ▪ Content areas: Redox, Equilibrium, Fossil fuel, …▪ Skills: Critical thinking, communication and

problem solving (which involves data collection and analysis)

Example 2a: designing a pamphlet for persuading people to follow the principles of

green chemistry

Some students wish to persuading Hong Kong people to use PLA lunch box by using pamphlets

Learning elements: ▪ Content areas: Materials chemistry, Green

Chemistry▪ Skills: Creativity, critical thinking,

communication and problem solving, information technology

Example 2b: designing a poster for explaining the principle of a chemical cell

Some students wish to show the public the principle of a direct methanol fuel cell (DMFC) using posters

Learning elements: ▪ Content areas: Redox reactions, chemical cells

and electrolysis▪ Skills: Creativity, critical thinking,

communication and problem solving, information technology

Example 3: writing a report to present the scientific knowledge and concepts acquired

after a visit to an industrial plant

To explain how chemistry helps provide us with quality drinking water, some students wish to visit a water treatment plant and report their learning in a writing form

Learning elements: ▪ Content areas: Planet earth (water treatment)▪ Skills: Critical thinking, communication

Example 4: developing a multimedia artefact to illustrate the synthesis of polymers

To explain the chemistry involved in the formation of urea-methanal, some students wish to make use of a presentation software to present the process at a molecular level

Learning elements: ▪ Content areas: Materials chemistry (condensation

polymerisation)▪ Skills: Creativity, critical thinking, communication,

information technology
