In-Service Teacher Training Assessment in IGCSE Chemistry 0620 Session 1: Introduction to the Syllabus
Introductions Background Aim of training Welcome
Session 1 looks at: Syllabus aims The structure of the syllabus Assessment objectives The development of different skills The difference between formative and summative assessment
Aims of the syllabus (1): Relevance and application Relevance of chemistry to everyday life The social and economic aspects of chemistry The application of chemistry in solving problems Ethical and cultural influences
Aims of the syllabus (2): Practical skills Carrying out experiments Inventiveness Following instructions Accuracy and precision
Aims of the syllabus (3): Communication and objectivity Communication skills are important in everyday life Objectivity is an important part of science Science has some limitations and does not always provide answers
Structure of the syllabus (1): Overall structure There are 14 sections covering physical, inorganic and organic chemistry Some sections are divided into subsections
Structure of the syllabus (2): Overall structure The Core curriculum is applicable to all students The Extended curriculum builds on the core material and the relevant sections are placed next to each other
Structure of the syllabus (3): Overview of curriculum content 1 Particles (C + S)) 2 Experimental techniques (C + S)) 3 Atomic structure and bonding (C + S) 4 Stoichiometry (formulae and equations) (C+ S) 5 Electricity and chemistry (C + S) 6 Chemical changes (energetics) (C + S) 7 Chemical reactions (rates and equilibrium) (C + S)
Structure of the syllabus (4): Overview of curriculum content (2) 8 Acids, bases and salts (C + S) 9 The periodic table (C + S) 10 Metals (reactivity, metal extraction) (C+S) 11 Air and water (including gaseous pollutants) (C + S) 12 Sulphur (S) 13 Carbonates (C) 14 Organic chemistry (alkanes, alkenes, alcohols, acids & macromolecules) (C + S)
Structure of the syllabus (5): Core and Supplement What extra knowledge is required for the Supplement? What extra skills are required for the Supplement? Are there any parts of the Supplement and Core which overlap? Do certain topics appear in more than one of the sections 1-14?
Assessment objectives (1): General assessment objectives Assessment objective Weighting Knowledge with understanding 50% Handling information and 30% problem solving Experimental skills 20%
Assessment objectives (2): The scheme of assessment Paper Weighting Discriminating Core or grades Extension Paper 1 30% C-G C (multiple choice) Paper 2 (theory) 50% C-G C OR Paper 3 50% A-D C + E (theory) Papers 4 or 5 or 6 20% * C (practical)
Assessment objectives (3): Paper 2 or Paper 3? Paper 2 is based on the Core curriculum (80 marks) Paper 2 targets C-G candidates Paper 3 is based on the Extended curriculum (60 marks) plus 20 marks targeted at the Core curriculum Paper 3 targets A-C candidates Which paper should be chosen?
Assessment objectives (4): Practical assessment Paper 4 Coursework Paper 5 Practical Test Paper 6 Alternative to Practical
Assessment objectives (5): The importance of practical work Candidates need to be able to: Understand how to carry out practical procedures Record readings and construct tables of data
Assessment objectives (6): The importance of practical work Candidates need to be able to: Undertake tests for gases and ions Identify sources of error Suggest suitable techniques and apparatus for an investigation
Assessment objectives (7): Coursework (Paper 4) There are 4 strands: C1 Using and organizing techniques, apparatus and materials C2 Observing, measuring and recording C3 Handling experimental observations and data C4 Planning investigations
Assessment objectives (8): The role of teachers in practical work Provide students with opportunities to develop their practical skills Produce and assist with subjects for investigations Sources of information Advise students in the practicality of schemes they have chosen Suggest length of time and general treatment of the problem Exercise continuing supervision of the assessment
Formative assessment (1): Formative and summative assessment Summative assessment involves terminal testing and interim testing There is no individual feedback on summative assessments that involve public examinations Formative assessment involves assessing student progress on a regular basis There is always feedback to the student in formative assessment The feedback from formative assessments are used by the students to improve their performance
Formative assessment (2): The nature of formative assessment Formative assessment involves an interaction between the student and teacher The teacher is able to assess progress, for example by feedback on tests etc. True formative assessment encourages improvement in performance
Formative assessment (3): Ways of assessing progress Marking Feedback on tests Answers given to verbal questions Target setting Student self evaluation
