32
Features of NSS Chemistry Curriculum

• Contents of each topic
• Overview
• Learning Objectives Outcomes
• Suggested L/T Activities
• Values and Attitudes
• Science Technology Society and Environment

33
Learning Outcomes

• Learning outcomes expected in each topic are
  included with a view to communicate the depth and
  breadth of the curriculum, e.g. Topic II (g)
• recognise the existence of covalent molecules
  with non-octet structures
• draw the electronic diagrams of some non-octet
  molecules such as BF3, PCl5 and SF6

34
Environmental Chemistry

• Science-Technology-Society-Environment (STSE)
  connections are included in topics of the
  compulsory and elective parts.
• Knowledge and concepts related to the environment
  are enhanced, e.g. pros and cons of using
  supercritical carbon dioxide and water as
  solvents instead of organic solvents

35
Features of NSS Chemistry Curriculum

• Green chemistry is introduced in the elective
  part (i.e. topic XIII XIV).
• The knowledge and concepts related to
• greening of industrial processes
• manufacturing uses of green materials
• are included .

36
Green Chemistry an introductory text

• Mike Lancaster (2002)
• Cambridge Royal Society of Chemistry

37
Investigative Study

• Page 85 (Eng), Page 73 (Chi)
• I.S. is included in and is presented as a
  separate topic of the curriculum (i.e. topic XVI)

38
Investigative Study

• I.S. is a collaborative (group-based) scientific
  experimental investigation
• Finding out
• Gather first-hand information

39
Investigative Study

• Learning objectives
• Justify an investigation plan
• Suggest how to improve validity and reliability
  of an investigation
• Communicate with precise language
• Evaluate conclusions and process of investigation

40
Investigative Study

• Time allocated 18 hours in the curriculum
• Some learning experience like how to work
  together in a group , how to select an
  appropriate question for the study, are
  required before the conduction of I.S. page 86
  (Eng) and page 74 (Chi)

41
Investigative Study

• Five stages
• Searching for and defining questions for
  investigation 3 hrs
• Developing an investigation plan 4 hrs
• Conducting the investigation 4 hrs
• Organizing and analysing data for a justified
  conclusion 4 hrs
• Presentation of findings using written reports,
  posters and other means 3 hrs
• Mostly done within school hours!

42
Investigative Study

• Examples
• Variation of the amount of active ingredient in a
  bleach solution upon storage.
• Analysis of vitamin C content in citrus fruits or
  vegetables.
• Extraction of naturally occurring chemicals and
  testing their uses, e.g. natural pest repellent
  from citrus fruit peelings.
• Synthesis of a photodegradable soapy detergent
  and investigating its characteristics.
• Construction and testing of a chemical cell.

51
Curriculum Planning

• A curriculum for all students with a range of
  abilities and aptitudes
• Curriculum planning at the school level is
  definitely required!

52
Learning Difference and Curriculum Planning

• Option 1 Include all the topics of the
  compulsory part in the school plan
• Option 2 Include all the topics of the
  compulsory part and appropriate components of the
  elective part in the school plan
• Option 3 Select key components of the topics in
  the compulsory part and appropriate components of
  the elective part in the school plan

53
Teachers Network and Learning Community

• To provide opportunity to share experience on
  issues like
• Working with students with a range of abilities
  and aptitudes
• How to plan school-based curriculum
• If you like to join the network, send your email
  address to us!
