Transcription

1 Physics Subject Specialism Training 2016/17 Overall aims Address gaps in subject knowledge and adoption of new teaching approaches. Increase confidence to extend the most able students. Introduce new ideas for student practical activities and class demonstrations Introduce and optimise required practical activities for GCSE Develop use of scientific models, identify and challenge misconceptions. Review what is required for GCSE exams and enhance teaching of exam technique. Review maths requirements and the teaching of maths skills within Physics Two sets of 5 face to face days are offered and whilst it is anticipated these will run over two years some may wish to attend only the Key Stage 4 course or take both concurrently. Each session will be a balanced mixture of theory, demonstrations and practical investigations and will include discussion of how to enliven our teaching, how best to teach the maths involved and frequently refer to what is required in the GCSE exam. Tasks will be set between these sessions to practise skills, initiate further discussion, to reflect on and enhance current practice and address the wider requirement to teach scientific thinking and working scientifically. Webinars will be used to offer extra support and cover such topics as maths skills, astronomy and exam technique. Our physics TSST course carries IOP community accreditation for 2016/17 Tutor: Simon Fitzjohn Ex-Head of Science with over 30 years experience at teaching Physics, Electronics and Computing up to A-Level. Now enjoys working on subject specialism training such as these, being a tutor on the Troops to Teachers programme, A level Physics examining and even some overseas consultancy. Interested to develop new apparatus and accepts that it often falls to Physics teachers to be the first to embrace new technology and exploit technological advances. A RaspberryPi, Python programming enthusiast who is also looking forward to help kids do real science with their BBC micro:bits. He remains convinced that most of us learn best from hands-on experience, We often ask our students to imagine things that can t been seen so it s incumbent on us to get the very most from the experiences we do create in the laboratory.

2 Key Stage 3+ These sessions will develop the Key Stage 3 topics which underpin work at GCSE and will include optimising 3 of the core practicals as described in the subject specifications for first examination in 2018 Day 1 Content Matter States of Matter Physical properties Particle model Changes of state Pressure caused by gases Outcomes Use of atomic models Measurement of density (Core practical, part CP1) Demonstration of phenomena associated with changes of state Qualitative investigation of melting ice (Core practical, part CP1 ) Appreciation of how pressure is caused by gases Use of water manometers Application of simple Gas Laws (ie P 1 V 1 =P 2 V 2 ) Day 2 Day 3 Static Forces Non-contact forces (Electrostatic, Magnetic and Gravitational forces) Contact forces Forces and Motion Measuring speed Force and acceleration Measuring acceleration Newton s Laws Appreciation nature of paired exchange of push/pull forces Magnetic fields and forces between magnets Force on a current carrying conductor Simple operation of DC motor Meaning of weight Equilibrium turning forces, moments Pressure in fluids Some fun ways to demonstrate and measure pressure.

Perform investigations with convex lenses and use ray diagrams to explain formation of real and virtual images. Observation of total internal reflection and discussion of importance and uses of fibre optic cables.
