1. Changing practices: The role of curriculum development Robin Millar University of York S-TEAM mid-project Conference, Glasgow 14 October 2010

2. Can science education curriculum redesign provide significant improvement on its own, or is additional change necessary, for example in assessment or pedagogy?

3. curriculum assessment pedagogy Changing classroom practices what we teach how we teach how we check what students have learned

4. curriculum assessment pedagogy Changing classroom practices For significant improvement, we need to address all three.

5. Twenty First Century Science

6. What is Twenty First Century Science? A suite of 6 inter-related courses Two-year courses (students aged 15-16) Each taking 10% of total curriculum time Each leading to a General Certificate of Secondary Education (GCSE) qualification Designed to provide a range of options to suit students with different interests and aspirations

7. Starting point “A central fact about science is that it is actually done by a very small fraction of the population. The total of all scientists and engineers with graduate level qualifications is only a few percent of the whole population of an industrialised country. Thus the primary goal of a general science education cannot be to train this minority who will actually do science.” Ogborn, J. (2004). Science and Technology: What to teach? In M. Michelini (ed.) Quality Development in Teacher Education and Training (pp. 69-84). Udine: Forum.

Quality Development in Teacher Education and Training (pp. 69-84). Udine: Forum. So what is the primary goal of a general science education?

9. Beyond 2000 report “The science curriculum from 5 to 16 should be seen primarily as a course to enhance general ‘scientific literacy’.” How can we achieve this, whilst also catering for the needs of future specialists?

10. The school science curriculum has two purposes : A design challenge to develop the scientific literacy of all students to provide the first stages of a training in science for some students These require distinctively different approaches Can we resolve the tension between them, by designing a curriculum structure that addresses both?

11. Science curriculum model for 15- 16 year olds (pre-2003) Double Award GCSE Science 20% of curriculum time Counts as 2 GCSE subjects Taken by >80% of students - with <10% doing less (1 GCSE) and <10% doing more (3 GCSEs)

12. GCSE Science 10% curriculum time Emphasis on scientific literacy (the science everyone needs to know) for all students GCSE Additional Science 10% curriculum time or GCSE Additional Applied Science 10% curriculum time for some students Twenty First Century Science curriculum model

13. citizens future scientists citizens future scientists

14. Twenty First Century Science Core: for all students Additional options: for some students

15. GCSE Science Core course for all students With an emphasis on developing students’ scientific literacy

16. How is it different from previous science courses at this level? More obvious links to the science you hear, or read about, out of school Some new content, for example: risk evaluating claims about correlations and risk factors clinical trials More emphasis on Ideas about Science in the context of evaluating scientific knowledge claims More opportunities to talk, discuss, analyse, and develop arguments about science and about its applications and implications

17. Ideas about Science All data are uncertain: how to assess uncertainty and deal with it How to evaluate claims about correlations and causes Scientific knowledge claims are of different kinds – ranging from established ‘facts’ to tentative explanations How the scientific community works: peer review How to express and compare levels of risk, and weigh up risks and benefits The issues which applications of science raise, and how individuals and society decide on these

18. Science Explanations The ‘big ideas’ of science: The idea of a ‘chemical reaction’: rearrangement of atoms; nothing created or destroyed The idea of ‘radiation’: energy travelling outwards from a source; may go through objects, or be reflected or absorbed …. The gene theory to explain inherited characteristics etc.

19. Course structure Science Explanations Modules (on topics of interest) Ideas about Science etc.

20. What worked, what didn’t?

21. Internal evaluation of pilot trial Almost all pilot school teachers thought the core Science course was significantly different from previous science courses Relates to students’ experiences and interests Stimulates, and provides more opportunities for, discussion More opportunities for students to contribute ideas and views Over 90% of pilot school teachers judged the course successful in improving their students’ scientific literacy 70% thought their students’ response in science classes was noticeably better than in previous years For more detail, see: Millar, R. (2006). Twenty First Century Science: Insights from the development and implementation of a scientific literacy approach in school science. International Journal of Science Education, 28 (13), 1499-1522.

22. Positive teacher and student response Students report more interest in reading about science Support and training were essential to improve teachers’ understanding of course aims and confidence with the new teaching styles involved Teachers needed time to assimilate the new approach Summative tests (external examinations) developed by the Awarding Body did not fully reflect the course developers’ aims and intentions External evaluation of pilot trial For full report, see: http://www.21stcenturyscience.org/data/files/c21-evaln-rpt-feb07-10101.pdf

23. What did we learn from the pilot trial? It is possible to make a ‘scientific literacy’ course which teachers find workable, and many find attractive which improves student engagement with science which integrates science content and ideas about science Together with Additional Science, this can provide good access to more advanced study Teachers need time, and considerable support, to take on more discussion-based teaching approaches and methods, and make these work well It is difficult to develop and implement forms of assessment that encourage and support the teaching of science for scientific literacy Examiners’ imagination External constraints

28. Can science education curriculum redesign provide significant improvement on its own, or is additional change necessary, for example in assessment or pedagogy?

29. Some reactions Curriculum redesign can trigger some positive changes Matching curriculum content better to students’ needs and interests Leading to classes that are more rewarding for many teachers Successful implementation usually requires a change in pedagogy Activities that involve new and unfamiliar teaching methods A new approach may involve a reappraisal of values (views of purpose and priorities of school science) ‘… the main reason for pupils’ dissatisfaction with lower secondary school science lies with the impoverished forms of pedagogy that are a feature of most science lessons.’ (Galton, M. (2009). Primary-secondary transfer in science. Perspectives on Education, 2. London: The Wellcome Trust.)

30. Assessment is the most significant driver of real change It defines the real learning goals It facilitates communication between designers and users If it is ‘high stakes’, it strongly influences classroom behaviours The idea of ‘backward design’: Wiggins, G., & McTighe, J. (2006). Understanding by design, 2 nd edn. Upper Saddle River, NJ: Pearson.

32. Supplementary question How can the research base in science education best be mobilised to support science teachers in schools?

33. Some responses Let’s be realistic about the ‘research base’ Research has been more successful in identifying learning difficulties than in testing solutions We know more about what learners think than about how to change what they think We know a lot about students’ attitudes to science, but less about how to change these

34. How can the research base best be mobilised to support teachers? Research-informed teaching & learning sequences key design criteria (Andersson & Bach); ‘critical details’ (Viennot); design briefs (Leach & Scott) Research-informed resources and tools EPSE project: diagnostic questions ‘Getting Practical’ audit tool: focused reflection on current practice
