Outline Elective part of the curriculum Curriculum Planning –Learning & teaching sequence in NSS Chemistry –Subject Combinations Brief report on assessment aspects –Public Examinations –School-based Assessment

Need to have detailed reading of the curriculum guide so as to attain a high level of understanding.

Need to have professional discourse to develop some understanding of the topics in the elective part so as to make informed choices.

Need to develop a plan for your school-based chemistry curriculum, with reference to the NSS Chemistry and Combined Science C/A Guide.

NSS Chemistry Curriculum

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

Elective Part of the Curriculum: Chapter 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?

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

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

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

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.

Curriculum Planning

Interfacing Science (S1-3) Chemistry (S4) CS (Chem S4) CS (Chem S5,6) Chemistry (S5,6)

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 …

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

Chemistry Part of the Curriculum 270 hours 135 hours

Two Science Subjects

NSS Chemistry and NSS Combined Science 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 1: Chemistry + Combined Science (Bio/Phy) rather than Chemistry and Biology only Eg 2: Physics + Combined Science (Chem/Bio) + BAFS Eg 2: Physics + Combined Science (Chem/Bio) + BAFS –A watered down curriculum? Building a basis for further development in chemistry related study or career

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 Chemistry Part (Total 135 hours) 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.

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

Catering for learners’ diversity Concern: Flexibility of curriculum for students with different needs Review: Certain flexibility already implemented in the curriculumCertain flexibility 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

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?!Core and extension arrangement?!

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 –… … …

Prepare a 5-minute presentation to share your views with other fellow teachers
