2.2.1 Circuit Symbols (a) recall and use appropriate circuit symbols as set out in SI Units, Signs, Symbols and Abbreviations (ASE, 1981) and Signs, Symbols and Systematics (ASE, 1995); (b) interpret and draw circuit diagrams using these symbols.

TASK: Link these symbols to names & functions…. cell Indicator / light source Low resistance, connect in series resistor No more semi circles! thermistor High resistance, connect in parallel Electric motor ammeter Resistance falls as temp rises Light emitting diode Resistance falls as light level rises Light dependent resistor Emits light when forward biased heater voltmeter of a specific value diode Conducts when forward biased Variable resistor Many cells = a battery

Connection Connect your learning to the content of the lesson Share the process by which the learning will actually take place Explore the outcomes of the learning, emphasising why this will be beneficial for the learner Demonstration Use formative feedback – Assessment for Learning Vary the groupings within the classroom for the purpose of learning – individual; pair; group/team; friendship; teacher selected; single sex; mixed sex Offer different ways for the students to demonstrate their understanding Allow the students to “show off” their learning Consolidation Structure active reflection on the lesson content and the process of learning Seek transfer between “subjects” Review the learning from this lesson and preview the learning for the next Promote ways in which the students will remember A “news broadcast” approach to learning Activation Construct problem-solving challenges for the students Use a multi-sensory approach – VAK Promote a language of learning to enable the students to talk about their progress or obstacles to it Learning as an active process, so the students aren’t passive receptors
