VCE ChemistryUnits 3 and 4 2008–2011VCAA and CEA Implementation WorkshopsTerm 2 2007
Purpose of the workshop
● Highlight differences between the reaccredited study design and the current study design with focus on Units 3 and 4
● Introduce the assessment requirements for Units 3 and 4
● Provide some time for discussion● Provide some sample teaching and learning programs
for Units 3 and 4● Seek feedback as to future professional development
and support
Study design: structural changes
● A set of key skills applicable to all units
● Two areas of study in each Units 1–4
● Newer and fewer assessment tasks
● Glossary
● Two year implementation− Units 1 and 2 in 2007− Units 3 and 4 in 2008
Study design: content changes
● Key concepts ‘spiral’ through each unit● Choice in Unit 4 area of study● ‘The Periodic Table’ introduces the study of VCE
Chemistry in Unit 1● ‘Rationale’, ‘Aims’ and ‘Introduction’ for each unit
and area of study have been updated● More detail on safety and laboratory time provided● More detailed ‘Advice for teachers’ section
Study design: summary of new content
Unit 3 - additional techniques of analysis, biochemical fuels, forensic analysis, design new medicines
Unit 4 - waste management and health and safety, choice of industrial chemical, sustainability of energy sources
Assessment
● Number of examinations− one for Unit 3 mid-year− one for Unit 4 end-of-year
● Contributions to study scores− 34% School-assessed Coursework
(17% each for Units 3 and 4)− 33% mid-year examination− 33% end-of-year examination
● Time allocated for each exam− One and a half hours
plus 15 minutes reading time
Key skills (Study design page 12)
● Apply to each unit
● Developed, used and applied in a variety of contexts
● Demonstrate skills at a progressively higher level as the complexity of knowledge increases
● Examinable for Units 3 and 4
Structure
Unit 1The big ideas of chemistry
Unit 3Chemical pathways1. Chemical analysis2. Organic chemical
pathways
Unit 2EnvironmentalChemistry
Unit 4Chemistry at work1. Industrial chemistry2. Supplying and using
energy
1. The Periodic Table2. Materials
1. Water2. The atmosphere
Unit 3: Chemical pathways
Area of study 1 Chemical analysis
Area of Study 2 Organic chemical pathways
Outcome 1Evaluate the suitability of techniques and instruments used in chemical analyses
Outcome 2Identify and explain the role of functional groups in organic reactions and construct reaction pathways using organic molecules
Unit 3: School-assessed Coursework
Three assessment tasks
An extended experimental investigation that can be drawn from either area of study 1 or area of study 2
AND
From the area of study NOT used for the extended experimental investigation
Unit 3: School-assessed Coursework (cont.)
A written report of one practical activity
AND
One task selected from the following:● a response to stimulus material in written, oral or
visual format● an analysis of first or second-hand data using
structured questions● a report in written, oral, multimedia or visual
format related to chemical pathways
Activity 1
Selection of assessment tasks for Unit 3
Unit 4: Chemistry at work
Area of study 2Supplying and using energy
Area of study 1Industrial chemistry
OutcomeAnalyse the factors that determine the optimum conditions used in the industrial production of the selected chemical
OutcomeAnalyse chemical and energy transformations occurring in chemical reactions
Unit 4: School-assessed Coursework
Assessment tasks
A summary report including annotations of three practical activities drawn from either area of study 1 and area of study 2
AND
From the area of study NOT used for the summary report
Unit 4: School-assessed Coursework (cont.)
A written report of one practical activity
AND
One task selected from the following:● a response to stimulus material in written, oral or
visual format● an analysis of first or second-hand data using
structured questions● a report in written, oral, multimedia or visual format
related to chemistry at work
Activity 2
Selection of assessment tasks for Unit 4

VCE Assessment Handbook Chemistry
● Section 1 Administrative Procedures
● Section 2 Chemistry Assessment Advice
● Section 3 Assessment Support Materials and
Further Resources
Section 2: Chemistry Assessment Advice
● Outcome statement(for each area of study in each unit)
● Task− Description− Designing the assessment task− Resources and scheduling− Performance descriptors
● Information about examinations
The Performance Descriptors
● Guide for expected standards when setting and marking assessment tasks
● 5 mark ranges provided
● Each range is accompanied by a list of typical performance
● Each mark range allows for discrimination
Activity 3
Using Performance Descriptors
Exams
Exam 1 (June)● Multiple choice● Short answer● Data booklet● Equal weighting of
each area of study
Exam 2 (Nov)● Multiple choice● Short answer● Data booklet● Equal weighting of
each area of study
Support for implementation
● Chemistry – a pathway to Emerging Sciences in Victoria, CD-ROMDepartment of Innovation, Industry and Regional Development (DIIRD)
● Ongoing professional development program such as RACI (VIC), VICS, STAV, CEA, GTAC, Ecolink (Bacchus Marsh), Victorian Science Space Centre
