Putting Research into Practice:the EPSE Project Jenny Lewis CSSME [Phil Scott; John Leach; Andy Hind; JaumeAmetller; all the teachers who worked with us]
Alternative/everyday Conceptions ‘Communicative Approach’ Learning Demand EPSE Evidence based Practice in Science Education Research informed design, implementation and evaluation of teaching sequences
Specify the teaching goals • For example • to introduce, andsupportthe developmentof, the ideas that: • an electric current consists of a flow of charge. • the electric current has the job of transferring energy • to draw attention to, andtoemphasise, the ideas that: • the electric current does not get used up • it is the energy which is transferred in resistances to make things work.

Patterns of talk: plant nutrition sequence Lesson 5 Explains the use of minerals from the soil; compares and contrasts animal and plant nutrition. Interactive authoritative Lesson 1 Uses ‘What if ..’ scenarios and brainstorming to explore and make explicit students’ ideas about food. Interactive dialogic Lesson 2 Presents a simple explanation of photosynthesis for students to challenge through discussion of ‘I don’t believe it’ statements. Interactive dialogic [non-interactive dialogic] Lesson 4 Presentation and consolidation of the science explanation; revisiting the ‘What if’s..’ Interactive authoritative • Lesson 3 • Uses 3 practical activities to make the key science ideas more plausible: • Demonstration: gas + liquid can produce a solid • Investigation: does gas have mass? • Atomic Jigsaw: glucose from CO2 and H2O • Mixing non/interactive; dialogic/authoritative
Did the students learn anything? Did they learn more? How did we know?
Evaluation of the learning outcomes • Pre, post and delayed post test written questions with case study and control groups • Responses were coded for: • correct or incorrect prediction (about the behaviour of a simple circuit) • the extent to which a scientific model was drawn upon in the explanation (‘no use of’ , ‘some or inconsistent use of’, ‘use of most aspects of’ the scientific model)
‘Case study’ and ‘Comparison group’: student explanations in the post-test
Writing the sequence • Brief • Teacher friendly language • Signposting (the icons)
