3. 3 1st consultation exercise (Oct 04 – May 05) Implementation schedule Core and elective subjects Career orientated courses

4. 4 2nd consultation exercise (Jun 05 – Jan 06) Benchmarking (UCLES, IBO, WMIER) Meetings with chemistry/science department of various universities and colleges Focus group meeting Questionnaires from secondary schools

5. 5 Comments and Concerns from questionnaires –Public examination: weighting, SRA, duration and question types of written papers –SBA and investigative study: teachers’ and students’ workload, weighting, class size, fairness, requirements and assessment –Curriculum content: cater for learner differences, teaching hours, resources

6. 6 Response to comments Re-examining teaching time, learning objectives and outcomes Proposing suggestions to facilitate teachers to plan a flexible curriculum Proposing suggestions on how to cater learners diversity

7. 7 Response to comments Delivering professional development programmes of NSS Chemistry for teachers Developing exemplars for learning, teaching and assessment in task groups

8. 8 3rd consultation exercise (Sep – Nov 06) Focus on public assessment for NSS Public examination: Paper structure, weighting, duration SBA: Weighting, design, timeline, teachers’ effort, students’ effort, authentication
