Mathematics and the transition from Alevels to physics and engineering degrees

Professor Peter Main

Mathematics in STEM: Transition Issues

RAEng 16 th January 2012 peter.main@iop.org

Two Studies

Mind the Gap

 A study based on the perceptions of students and academics

 Students include those who did choose physics or engineering as well as those who could have done but chose not to.

SCORE Maths in Science A-levels

Investigations and characterisation of the mathematical content of science A-levels in absolute terms and relative to what is in the curriculum

Also feedback from academics and employers

Mind the Gap : Specific objectives

To understand the extent to which students are prepared to deal with the maths aspects of physics and engineering undergraduate courses

Transition from A-Level to degree

Reactions to mathematical aspects of degree courses

Most and least challenging mathematical aspects

Gaps in preparation

To understand reasons for not pursuing physics to degree level

“Starting my A-levels, I was thinking about what degrees I might want to do.

My teachers said if you want to do Maths or Physics, you should try Further Maths, so that you’re prepared for degree level.

It made the A-level Maths seem easier in comparison” Physics student

A number of factors steered potential students away from

Physics degrees

Aptitude for

Maths at

GCSE = study at A-

Level

Maths &

Physics are a logical fit

Physics perceived more as

‘learning’ than

‘problem solving’

Compared to Further

Maths,

Physics not as challenging

Lack of awareness of potential career options

“I guess it’s the only thing that truly made sense to me I was good at it and the problem-solving and satisfaction that you get from that made me more enthusiastic about it. It just seemed like the natural thing to want to study it further” Maths student

“What you could do with a Physics degree was never mentioned to me or gone over in my classes. I don’t think it was ever mentioned. A lot of people who were interested in Physics did Engineering”

... long-term consequences

“The lack of any proper maths at A-Level

Physics meant that I felt quite overwhelmed and had to learn the skill of deriving physical meaning from maths, something I'm still having to pick up on”

Physics student

This can prove to be an obstacle throughout the course

A small number (ranging from 5-15%) drop out each year, but this cannot be directly linked to a struggle with mathematical content

“Before I came to university I was really confident with my mathematical ability. The first year I was good, but now the problems are getting more and more vast, hard and complicated. Sometimes I look at a problem and barely even attempt it because I just get it in mind that it's really difficult. Two years ago I would never have done that, so it’s starting to get a bit more daunting” Physics student

“Mostly they’ve covered a wide and appropriate range of mathematical concepts and techniques.

I do think they lack practice and fluency. I think many of them have a rather poor feel for numbers and find it very difficult to do estimates, quick checks, if there is a reasonable answer […] I think they’re quite poor at unstructured problem solving”

Physics academic

A number of reasons offered for perceived lack of fluency

TEACHING TO EXAMS

Many academics believed that A-Level Maths is taught too heavily to exam

Some agreement from students

 Equations/ techniques taught by rote

 Leads to a lack of understanding of the context in which techniques should be applied

“I always say you often see equation democracy. If you look at A-Level Maths text books nowadays they look like every equation is as important as every other equation. The only way you could possibly do maths is to memorise every equation in the world, whereas there are relatively few equations that are important….” Engineering academic

“I was startled by how different university level maths is, lots more rigour. I wasn't very well prepared for this by my school's teaching to pass exams” Physics student

A number of reasons offered for perceived lack of fluency

COMPARTMENTALISATION

 Too little connection between Maths & Physics at A-Level

 Too little connection between modules

 Further compounds inability to see the link between mathematical techniques and their place within Physics/ Engineering

“If you learn technique a in a unit, let’s say, in a module on technique a, you are never ever expected to use it in a course or module in something different. So there’s absolutely no transferable skill that they are learning…..

They’ve never seen maths as toolbox for physics before. It is purely down to compartmentalisation” Physics academic

Possible solutions suggested from academic perspective

“Introducing more mathematical, problemsolving type questions into the Physics A-

Level seems more appropriate. Getting across the importance of Maths and practising how it is used in Physics would be very valuable”

Academic

“Change the way Maths is taught at A-

Level; provide the fundamentals, not just recipes to apply in specific cases”

Academic

“The content [of Further Maths A-Level] is clearly helpful. In their first semester here, a lot of the

Maths that we’re teaching them is essentially the content of A Level Further Maths, because we take students who haven’t had maths. So they have a gentler lead in and more time to get used to the differences in style and shape of problems that we’re asking them to tackle” Physics academic

“If they were music students they would need to practice their scales.

They just need more practice, until algebraic manipulations, powers, logs etc all come naturally and quickly to them. Then they can start to play the sonatas, concertos and symphonies that are Physics”

Academic

“Those who have taken Further Maths at A-level are fairly well-prepared. It appears necessary to give those without this background a different introduction. It is not so much a question of mathematical ability but more using maths in a Physics problem

– reducing a Physics problem to a Maths problem that they can solve.”

Academic

Key points

Lack of awareness of what a physics degree involves or can lead to

A level should give a better foretaste of degree work

Stronger careers promotion needed

Academics and students recognise problems with maths preparation

 Academics perceive a greater problem than students

Further Maths is regarded as helpful for degree preparation

Practice makes perfect

Teaching to the Test and Compartmentalisation at

A level

Does not encourage use of maths within physics

Does not give a realistic foretaste of degree work

Why this matters

1. Influence on what is taught

• Authenticity of experience of the sciences

• Providing tools to fully understand the science

• Rewarding explanations

• Preparation for further study

2. Confidence in standards

3. Confidence in the system
