1. Workshops on Understanding and Interpreting NSS Chemistry Curriculum Raymond WH FONG Science Education Section EDB

2. Outline • Elective part of the curriculum • Curriculum Planning • Learning & teaching sequence in NSS Chemistry • Vertical and horizontal coherence • Assessment aspects • Public Examinations • School-based Assessment

3. Curriculum Framework • Compulsory Part (198 hours) • Elective Part (52 hours) • Investigative Study (20 hours)

4. Elective Part of the Curriculum: • Chapter 13-15 of the C/A Guide • Select two topics out of three (26 hours per topic) • Have to be taught the topics in S6? • Are these topics most challenging ones?

5. Industrial Chemistry • Importance of industrial processes • Rate equation, Activation energy and Catalysis & industrial processes • Industrial processes: • Haber process • Chloroalkali industry • Methanol synthesis • Green Chemistry*

6. Materials Chemistry • Naturally occurring polymers • Synthetic polymers and plastics • Metals and alloys • Synthetic materials in modern ways of living • Green Chemistry*

7. Analytical Chemistry • Detecting the presence of chemical species • Separation and purification methods • Quantitative methods of analysis • Instrumental analytical methods • Contribution of analytical chemistry to our society

8. Reading Time Knowledge and understanding? Skills? Values and Attitudes? STSE?

9. Cast Your Vote(You have two votes) • Industrial Chemistry – ( ) • Materials Chemistry – ( ) • Analytical Chemistry – ( ) • Why?

10. Discussion Questions • Identify the sub-topics in the compulsory part required to support the learning of the topics in the elective part of the curriculum. • Compare and contrast the cognitive demands of the topics in the elective part. Are the demands roughly the same? Should the demands be the same? • Identify the sub-topics in each of the topic in the elective part that are difficult to your students. For some reasons, you have included the topic in your teaching plan, what would you do to facilitate students’ learning.

11. Prepare a 3-minute presentation to share your views with fellow teachers

12. Curriculum Planning

13. Interfacing with Junior Secondary Science Curriculum • “Stepping stones” for senior secondary science curriculum!? • Knowledge and skills required for conducting scientific investigation • Knowledge and understanding • Uses of fossil fuels & related environmental impacts • Common acids and alkalis • … • Practical skills • Tests for hydrogen, oxygen, carbon dioxide, … • Separation techniques • …

14. Suggested Learning and Teaching Sequences

15. Curriculum Integration

17. Progression of Study (2/2)

18. The Combined Science Curriculum

19. Chemistry Part of the Curriculum: • 135 hours • There are no elective topics in the chemistry part of the curriculum • Are the topics challenging ones? • Cognitive demand is appropriate: exceed the current S4-5 Chemistry Curriculum, and the coverage is balanced

20. 270 hours 135 hours 135 hours Chemistry Part of the Curriculum

21. 2X Two Science Subjects

22. NSS Chemistry and NSS Combined Science • NSS Combined Science • Designed for students intended to study two subjects in science KLA • Eg 1: Chemistry + Combined Science (Bio/Phy) rather than Chemistry and Biology only • Eg 2: Physics + Combined Science (Chem/Bio) + BAFS • A watered down curriculum? Building a basis for further development in chemistry related study or career

23. Chemistry Part (Total 135 hours)

24. Combined Science • Assessment tasks: “Volumetric Exercise” and “Experiment” should be incorporated into normal learning and teaching • Investigative elements can be included into the experiments • There is no need to do investigation in the NSS Chemistry’s way

40. Catering for learners’ diversity • Concern: Flexibility of curriculum for students with different needs • Review: Certain flexibility already implemented in the curriculum • Response: • provide suggestions to facilitate teachers develop a flexible curriculum for students • provide suggestions to teachers on how to cater differences at learning and teaching • include diverse assessment items • provide PD opportunities for teachers to enhance their knowledge and skills in understanding the curriculum and how to deal with learning differences

41. Catering for learners’ diversity • Possible arrangements: • Complete the entire curriculum but focus more on the less demanding sub-topics • Focus more on the compulsory part and put less emphasis in the elective part • Focus only on the compulsory part, and skip the topics in the elective part • Core and extension arrangement?!

42. Curriculum Planning Exercise • Devise a draft plan for learning and teaching of NSS Chemistry for a hypothetical school or share your initial plan, which includes • background information of the school • a desirable learning and teaching sequence of the compulsory part • how would you implement investigative study • rationale for selecting topics in the elective part • means to cater for learners’ diversity • … … …
