3
Need to have detailed reading of the curriculum
guide so as to attain a high level of
understanding.
4
Need to have professional discourse to develop
some understanding of the topics in the elective
part so as to make informed choices.
5
Need to develop a plan for your school-based
chemistry curriculum, with reference to the NSS
Chemistry and Combined Science C/A Guide.
6
Curriculum Framework

Discussion Questions

1. Identify the sub-topics in the compulsory part
   required to support the learning of the topics in
   the elective part of the curriculum.
2. 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?
3. 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.

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

The Combined Science Curriculum
23
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

24
Chemistry Part of the Curriculum
25
Two Science Subjects
26
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

27
Chemistry Part (Total 135 hours)
I. Planet earth 8 hrs
II. Microscopic world 21 hrs
III. Metals 22 hrs
IV. Acids and bases 28 hrs
V. Fossil fuels and carbon compounds 23 hrs
VI. Redox reactions, chemical cells and electrolysis 26 hrs
VII. Chemical reactions and energy 7 hrs
Simple investigations are subsumed in the lesson time suggested for each topic. Simple investigations are subsumed in the lesson time suggested for each topic.
28
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
  Chemistrys way

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

45
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?!

46
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
