    School Organisation Level

    School Curriculum Level

    Class / group Level

    Guidance and exemplars provided by C&A Guides, EDB 334 web

    Funding and support provided (e.g. staffing, grants, professional development)

    Facilities, Physical conditions for appropriate learning environment

    Systemic Level

    Wide choice of subjects, ApL courses & OLE Forming a task force to co-ordinate and lead

    Devising a Whole-school Policy

    Ethos building to value diversity and individual differences, as well as uniformity

    Human Resource Deployment:

    Strengthen communication with parents on student progress

    Partnership with community to motivate student participation in a wide range of learning activities and competitions

    e.g.

    Forming learning support team

    A dual class teacher system

    Assign a teacher to one level instead of a range of levels

    Arrange a teacher to the same class for 3 years

    Employ teacher assistants

    Pedagogy, Environment and Assessment to motivate learning

    Student learning profile to record progress (formative)

    Recognise non-academic achievements and participation in report cards

    Identify the core and extended / elective parts of the curriculum for different students

    KLA / Panels devise plans to cater student diversity

    Make adaptation to assessment, e.g. separate core and extended content in the assessment papers, introducing challenging questions in exam

    Learn from other teachers by sharing, peer observation, reflection on lessons and student feedback

    strategies:e.g. Multi-level activities, co-construction, learning portfolios

    Motivation Strategies

  • Students are more different than more alike.Teachers provide support for excellence for all rather than achieve same attainment in all.Teachers have to develop understanding why some students can learn while others cannot.Teachers provide scaffolds for learning.

    C. Questions and Answers

  • Science (S1-3)

    Chemistry (S4) CS (Chem S4)

    CS (Chem S5,6)Chemistry (S5,6)

  • Flexible Organisation

  • Organise the sequence of topics / concepts from fundamental to advance

    Use spiral arrangement Integrate some or all the related topics Adopt alternative teaching sequences Build on knowledge and skills learnt in other subjects

    Extra support in some topics for students Reference: Chapter 3, CAG 2007

  • S4: V. Fossil fuels and carbon compounds (20 hours) Some reactions like substitution reactions of

    hydrocarbons (alkanes and alkenes only) and halogens Addition polymerisationS5: XI. Chemistry of Carbon Compounds (27 hours) Complete yet brief organic synthesis, i.e. the synthesis

    of useful carbon compounds through inter-conversions between different functional groups

    Addition and condensation polymerisation, plus detailed study of the relation of structure and properties

  • Other spiral arrangement of topics in NSS Chemistry curriculum:

    I. Planet EarthXII. Patterns in the chemical world

    II. Microscopic World IVI. Microscopic World II

  • CAG(E), p.92

  • CAG(E), p.91

  • CAG(E), p.94

  • For instance, in the study of chemical kinetics, students are expected to make use of skills related to drawing a volume of gas against time graph to report the findings from an experiment. Knowledge and skills from junior / senior Mathematics will be useful.

  • Mathematics requirement Skills:

    Handling DataArithmetic operationsUse of standard form in expressing numerical quantitiesManipulation of algebraic expressionsUse of logarithms and exponentsUse and inter-conversions of ratios, fractions and percentagesConstructing and interpreting graphsApplication of geometry

    Handling Experimental Error Recognise Instrumental Accuracy

  • Cognitively More Challenging Topics of the Compulsory Part Microscopic world II Chemical reactions and energy Chemical equilibrium Chemistry of carbon compounds Patterns in the chemical worldElective Topics: Industrial Chemistry Materials Chemistry Analytical Chemistry

  • http://evises.evi.com.hk/chem/

  • The challenge is to ask yourself which is the most difficult topic in NSS Chemistry / Combined Science (Chemistry)1. Analyse the topic2. Identify the difficulties in the topic3. Deliberate on how to address the difficulties4. Design small / manageable tasks to address the difficulties

  • With the use of school intranet systems, teachers can provide students with (1) more challenging exercises for students, and (2) information about some interesting newspaper articles / television programmes, followed by discussion Example of contents: Daily encountered chemistry related news, e.g TV programmes, e.g. Master Joe, TVB Especially useful for engaging students out of lesson time

  • Providingmorechallengingexercises

  • Summerholidays

  • a collection of resource materials - for example, an article on Kevlar with detailed uncluttered description, schematic drawings of polymeric structures and photographs of bullet-proof vests made of Kevlar, to help students understand the relation between the structures of polymers and their properties;a learning task with clear procedural guidelines and reporting template - for instance, a worksheet with guiding questions to help students in planning their own experiments;

    CAG(E), p.116

  • guidance, in a variety of formats, on the development of cognitive abilities, and social and investigative skills - for example, showing a video clip on how to conduct an acid-alkali titration to enhance the acquisition of the practical skills required for a titration;teacher debriefings - for instance, the presentation of a clear conceptual framework at the end of an activity to help students who have difficulty in conceptualising the essence of the activity, or encounter obstacles that significantly hinder their learning, e.g. mind map
