The story so far
•
January exams have already been removed.
•
The timeline for A-level reform has shifted constantly since first announced
in 2012.
Initially announced new A-levels to start in 2014, but this has been pushed
back a year.
•
•
Boards have worked with universities to agree the new Subject Content for
A-level Biology, Chemistry, Physics and Psychology
•
Inter-board agreement on:
–
–
–
–
•
subject content
the future of practical work
strengthening the maths content of A-levels
changes to Assessment Objectives.
DfE and Ofqual consultations are yet to report.

What’s the same?
•
•
•
•
The vast majority of the subject content is the same.
60% of an A-level in Biology, Chemistry or Physics is the same for all
boards. There is very little change to this subject criteria.
40% can be different between boards.
The expected outcomes are the same: the same students would get the
same grades before and after the changes.

What has changed?
•
•
•
All A-levels are now linear.
AS is a separate qualification, but co-teachable with A-level
Some updated subject content:
– Momentum has moved into the AS
– Some re wording (e.g. angular velocity now in subject criteria, “stationary
waves” not “standing waves”)
– Mechanical properties of matter (e.g. Young modulus) added
•

•
Changes to practical assessment
40% of the marks on Physics papers will require the use of Level 2
mathematical skills
New Assessment Objectives

Planning for linear exams
•
•
“My students are used to modular”
AS content will be examined at a full A-level standard where possible.
Examples:
Multi-step calculations:
• AS: scaffolded question with steps laid out
• A-level: multi-step calculation that the students have to work through.
Using the A-level maths skills (e.g. exponential equations )on AS content.
•
Make links wherever possible.
–
–
–
–
•
Examples:
How can we use the equations of motion or fields in particle physics?
Practice using the equations of diffraction on electron waves.
Introduce students to exponential equations in AS through attenuation of light
through a substance.
Outcomes should be the same.

Activity: Move to linear
•
•
•
Spend a couple of minutes discussing how the move to linear may affect
your teaching.
What can you do now to make sure you’re ready?
What materials or examples could you use with your current students to
stretch them, that will help you to prepare?

Practical assessment
•
•
•
•
Internal assessment of practical skills will no longer contribute to A-level
grade
Endorsement for practical skills
15% of questions in written papers will be about practical work
Very likely to be a list of specified practicals that all students can be
expected to have done during the course.

Teaching practical skills
•
Use dual lesson objectives
– For the Physics content
– For skills, such as practical skills
– Focus on one specific area of practical
Lesson objective:
1. To understand the use of the Young
Modulus of a material
2. To be able to use a micrometer
3. To be able to combine uncertainties of
measurements to calculate the uncertainty
in the size of an area

What can’t be tested in exams?
•
Exam papers cannot test students’ abilities to
–
–
–
–
•
follow instructions
work safely
use equipment
make measurements
These will be assessed via endorsement.

What can be tested in exams? (1/2)
•
•
•
•
•
•
Justify choice of a procedure for investigating a scientific question using
scientific knowledge and understanding
Select and justify an appropriate sequence of stages to support the
gathering of valid evidence
Select and justify data collection methods that minimise error and will
produce valid and reliable data.
Select and justify the choice of apparatus and methods of deployment to
gather valid and reliable data.
Identify hazards and risks
Adapt approaches to control risk

What can be tested in exams? (2/2)
•
•
•
•
•
•
•
Identify key variables and propose how each may be controlled in order to
produce valid evidence
Explain why some variables cannot be controlled easily and how planning
reflects this
Assess the strength of evidence to support conclusions
Process data to identify relationships between variables
Interpret and evaluate varying and conflicting evidence
Represent data using symbols, tables and a variety of graphs
Evaluate planning and implementation to account for errors and anomalies
and it’s impact on conclusions in complex contexts

Planning ahead
•
In pairs or small groups:
– Take each statement and decide:
• Which practical experiences you would give your students to develop this skill?
• Should any of these be on our “specified practical” list?
• What questions you could ask to prompt thinking about these skills?
• What should AQA provide to support this statement?

Assessment Objectives - old
AO1: Knowledge and understanding of science and of How Science Works
a) recognise, recall and show understanding of scientific knowledge
b) select, organise and communicate relevant information in a variety of forms.
AO2: Application of knowledge and understanding of science and of How
Science Works
a) analyse and evaluate scientific knowledge and processes
b) apply scientific knowledge and processes to unfamiliar situations including those
related to issues
c) assess the validity, reliability and credibility of scientific information.
AO3: How Science Works
a) demonstrate and describe ethical, safe and skilful practical techniques and
processes, selecting appropriate qualitative and quantitative methods
b) make, record and communicate reliable and valid observations and
measurements with appropriate precision and accuracy
c) analyse, interpret, explain and evaluate the methodology, results and impact of
their own and others' experimental and investigative activities in a variety of
ways.

• in a range of theoretical and practical contexts;
• when handling qualitative and quantitative data, to solve scientific
problems.

Assessment Objectives in the classroom
AO1:
Teach the specification content – including practical procedures and
skills.
Test to ensure students know it.
Take out the scaffolding in AS questions- this will be required for the
full A-level.
AO2:
Give opportunities for students to apply their knowledge to unfamiliar
situations.
Ask them to design experiments using the skills they’ve used.
Allow lots of opportunities to use mathematical skills in a range of
contexts.
Give students data and ask them to carry out mathematical analysis
on it.
AO3:
Give students data and ask them to draw conclusions from the data.
Give students a conclusion and ask them to evaluate it.
Ask students to suggest ways to improve experiments.

Maths skills
•
•
•
•
The list of maths skills required for A-level Physics has increased
40% of marks in Physics papers will require the use of maths skills
These must be Level 2 (Higher tier GCSE) maths or above
Standard form is specifically excluded from being Level 2 maths.

Not Level 2 - Physics

How can you prepare for the new maths
requirements?
•
•
Consider if this will affect your entry requirements for A-level.
Dual lesson objectives
– One for the Physics content
– One for skills, such as maths skills
Lesson objective:
1. To understand Kirchoff’s laws
2. To be able to handle calculations involving
reciprocals

Activity: maths requirements
•
Look at the list of maths skills.
•
Discuss where you would:
– Introduce each skill
– Practice each skill
•
Remember that you potentially have two years to develop skills now.
