teaching physic the big ةةةةةةةةةةةةةةةة

Teaching physics is a vital part of education because it helps students understand the fundamental laws that govern the universe, such as motion, energy, electricity, and light. Physics develops critical thinking and problem-solving skills by connecting abstract theories with real-world applications. Through experiments, models, and simulations, students not only learn scientific concepts but also build curiosity and creativity. Teaching physics prepares learners for careers in science, technology, and engineering, while also enriching everyday life with a deeper appreciation of how the world works. In this way, physics education shapes both knowledge and innovation for the future.Teaching physics is essential because it introduces students to the fundamental principles that explain how the universe works. It covers key topics such as motion, forces, energy, waves, electricity, and modern physics, linking theory with everyday experiences. Physics education develops logical thinking, problem-solving, and analytical skills, which are valuable in both academic and practical life. By engaging in experiments, demonstrations, and interactive learning, students gain a deeper appreciation for science and technology. Teaching physics not only prepares learners for future careers in STEM fields but also inspires curiosity, creativity, and a lifelong passion for discovery and innovation.

1. Teaching physics:
the big picture

2. Learning outcomes
describe the scope of physics: physical phenomena across
many orders of magnitude in time and space
appreciate that similar (physical & mathematical) models can be
used to explain very different phenomena
discuss the nature of effective physics teaching, drawing on both
education research and classroom experience
recognise the importance of conveying the nature of physics
(‘fundamentals’) to learners
be able to use index notation for numbers very small or large

3. the nature of physics

4. What is physics?
In pairs
Consider some examples.
Work towards a definition. – e.g. aims, procedures, key
concepts or relationships
Plenary
compare ideas.

5. Ways of thinking about physics
•an eclectic range of subjects (including e.g. mechanics, heat,
waves, sound, optics), historically brought together under a
single name
•an experimental science concerned with ‘the extension of the
human sensory-motor arrangement’ (JD Bernal)
•science that models physical phenomena with a coherent set of
abstract concepts – particles, radiation and fields.
•science of the fundamental building blocks of matter and
interactions– reductionist view: ‘physics underpins all sciences’

6. Space & time exercise
based on Roger Blin-Stoyle (1997) Eureka:Physics of
Particles, Matter and the Universe. IOP Publishing
Each group needs: A3 sheets of blank paper, pencil

7. Understanding the natural world:
5 revolutions
1.ancient Greeks introduce mathematical reasoning (e.g. Euclid,
Archimedes ~ 300 BC)
2.Galileo and Newton (17
th
C) – explain motion of solid bodies in
terms of forces between their constituent particles
3.Faraday and Maxwell (19
th
C) – continuous fields, as real as
particles, pervade space
4.Einstein (20
th
C) – space-time, speed of light and gravity
(‘relativity theory’)
5.Einstein et al (20
th
C) – wave-particle interactions between
matter and radiation (‘quantum theory’)

8. The Institute of Physics
Unifying ideas in physics
A.Thematic ideas
B.The endeavour of physics (thinking like a physicist)

9. Richard Feynman
Nobel Prize in Physics, 1965
1981 Horizon programme,
The pleasure of finding things out

10. effective physics teaching

11. In the science classroom
What key factors can lead to student success
… or difficulties?

12. ‘Constructing entities’
‘As teachers’ skills develop, they learn a range of
different ways of representing and formulating ideas
in science which make them comprehensible to
students.’
(J Ogborn et al (1996) Explaining science in the classroom

13. Analogy and metaphor
Consider their roles in
•science
•science education, generally
•physics education

14. Fossils of old thoughts
In each case, what’s the origin of the term?
•electrical ‘charge’
•thermal ‘conduction’
•heat sink
•anode, cathode and ion
•symbol I for electric current
“To become acquainted with words in their full significance is to
know much about the things that they represent and about
thoughts which other people have had.” Clive Sutton (1992)

15. Figuring things out with words
‘blanket of cloud’
‘computer virus’
‘biological cells’
‘resistance of a wire’
‘harnessing water power’
‘the heart as a pump’
‘flowing in an electric circuit’
‘the eye as a camera’
Discuss in pairs: What does each phrase mean? What
is the analogy or metaphor from which it derives?

16. What ‘learning’ can mean
learning as an increase in knowledge
something done by the teacher rather than something you do to or for yourself
learning as memorising
‘getting it into your head’, ideas memorised but not transformed in any way
learning as acquiring facts or procedures to be used
skills and formulae as well as knowledge, but still no transformation
learning as making sense
trying to understand so you can see what’s going on, being able to explain things,
not just remember them
learning as understanding reality
you kind of see things you couldn’t see before, ‘everything changes’

17. High-quality learning
1.students must see the value of learning
2.students must believe they can do it
3.challenging goals (involving reasoning, not just reproduction)
4.feedback and dialogue on progress toward goals
5.general approaches: from known to unknown; from concrete to
abstract; structure first, then detail
6.time & repetition: multiple contexts, perspectives, representations
7.teach skills as well as content: study skills, thinking skills
- Geoff Petty (2
nd
ed, 2009) Evidence-based Teaching

18. Effective teaching
1.start from phenomena (familiar and unfamiliar) when developing
conceptual knowledge
2.engage with misconceptions
3.use a variety of approaches and contexts
4.develop procedural knowledge – how to analyse given situations,
how to solve problems quantitatively
5.practise qualitative and conceptual analysis – go beyond symbol
manipulation - Randall Knight (2004) Five Easy Lessons
Give students glimpses of ‘the big picture’ – making connections,
simplification & modelling

19. Domains of learning
•cognitive (conceptual): recalling facts, analysing &
synthesising information, applying knowledge
•affective: students take a personal interest in a subject and
learn to express and defend opinions and values. also self-
perception of oneself as a learner
•physical and behavioural: students gain skills in
manipulation and planning, also learn to work both
independently and alongside others in teams

20. Contextual reading
An overview of physics: popular, historical,
philosophical, or anecdotal
For example,
•J D Bernal (1972) The extension of man
•Bill Bryson (2003) A short history of nearly everything
•A Einstein & L Infield (1938) The evolution of physics
•Richard Feynman (1998) Six easy pieces
•R Feynman (1985) ‘Surely you’re joking, Mr Feynman!’

21. The student view
‘Students can tell if their teacher is really interested in
what they are teaching.’

•analysing how effective student learning is
•questioning and probing
•making judgements and drawing conclusions
