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

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

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

P1.5.2 Reflection

a) The normal is a construction line perpendicular to thereflecting surface at the point of incidence.

b) The angle of incidence is equal to the angle ofreflection.

c) The image produced in a plane mirror is virtual,upright and laterally inverted.

How can you explain these things...

NB: object distance (do), and the distance from the image to the mirror is known as the image distance (di)

As the angle of incidenceincreases towards the criticalangle ( glass = 420 ) therefracted ray gets weaker and the reflected ray getsstronger.
