Research findings: ‘Breaking the mould?’
An early study of AS Science for Public Understanding. Key findings:
Missed opportunities for exploring ideas about science
Many lessons seen to be teacher-led Few examples of discussion between students observed.

Research findings: ‘Valuable lessons’
A study by Ralph Levinson of the discussion of issues related to biosciences:
Humanities teachers comfortable with discussion – but not too concerned about the accuracy of the science.
Science teachers very concerned to get across the science – and uneasy about discussion.

Discussion in small groups –Making a start
Establish the ground rules Choose a topic that students can relate to Provide a structure (with clear roles where
appropriate) Define the outcomes Set a (short) time limit Minimal teacher interventions: procedural, not
judgemental

Some established discussion techniques
SnowballsDiscuss topic in pairs, then fours, then eights – working towards consensus
JigsawsIndividuals work as ‘experts’ on a section of a topic and then re-group. Needs advanced planning but does ensure participation of all.
Rainbow groupsStudents each given a different colour, say in a group of 4; they discuss in groups of same colour, then original groups reassemble.

Purpose 1: language
Developing the language needed to analyse and develop arguments
– e.g module B1 You and your genes Activity AB1.22 Gene therapy in the news

Purpose 2: clarifying knowledge and understanding
Discussing true/false statements– e.g module P2 Radiation & life Activity AP2.29 Global warming challenge
![Page 8: 1 Purposes of small group discussions. 2 Research findings: ‘Breaking the mould?’ An early study of AS Science for Public Understanding. Key findings:](https://reader036.fdocuments.us/reader036/viewer/2022072006/56649f445503460f94c65083/html5/thumbnails/8.jpg)
Purpose 3: data & explanations
Discussing possible evidence for claims– e.g module P1 Earth in the Universe
Activity AP1.23 What killed off the dinosaurs (based on a video) or
– GCSE Science F tier textbook, questions about continental drift on page 62 (refer to pages 60-63)
Making sense of evidence– e.g module B3 Life on Earth
Activity AB3.7 Life on Mars

Purpose 4: exploring issues Issues with an ethical dimension
– e.g module B1 You and your genes Activity AB1.21 Embryo selection: what should be allowed?
Issues with a technical and economic dimension
– e.g module C2 Material choices – Activity C2.16 Can it be done? Should it be done?
– Gaining insight into other viewpoints

Purpose 5: making decisions
Developing policy arguments based on information and evidence
– e.g module B2 Keeping healthy Activity AB2.11 Is it worth it?
– See module P3 Radioactive materials Activity AP3.28 What was said?
