~0’5’: students settle
down; teacher prepares laptop etc.

7 E Instructional Model

~5’20’: ConcepTests
using Kahoot! (see http://kahoot.it and http://getkahoot.com): students will do
conceptual multiplechoice questions, answering using their mobile devices.
If the percentage of correct answers is very low, then we may have
encountered a misconception. I will then take the time to try and clear up
the misconception.

Elicit and Engage

~20’40’: selected
students will take turns to do homework questions on the whiteboard. They
will explain their answers and workings to the rest. Students “in the
audience” may be called upon to clarify the workings. In the meantime, the
teacher will go around and check whether the students did their homework. The
homework of about five students will be collected and marked by the teacher.
Depending on the questions at hand, I may use applets to clarify.

Explore and Explain

~40’55’: students will
get a challenging problem to work on in groups of three or four. They will
write their workings on miniwhiteboards. This will help to make their
thinking visible. The groups will be decided on by the teacher before the
lesson. Each group will have students of varying ability (based on recent
test scores).

Elaborate and Extend

~55’60’:
I will highlight the main points of the problem the students did on the
whiteboards, giving a strategy to solve similar questions. I may use an
applet for this.
