Setting the
context
•
• Ask students the main stages of a cell
cycle
• Ask students what the essential
difference is between meiosis and
mitosis.
PowerPoint

Modelling and
deconstruction
•
To introduce the stages
and phases:
– Nuclear division:
prophase, metaphase,
anaphase, telophase
– Cytoplasmic division
Language aspect applied:
prefixes
•
teach students the key events in two
stages of mitotic cell division

Guided
construction
•
To explain the stages and
phases
Language aspect applied:
Temporal explanations
•
Guide students to demonstrate and
present the stages using “ice-bar stick”
model in pairs Language aspect
applied: Visual presentation.
• Ask students to explain the stages with
biological terms.
In the guiding phase, teacher will use
language such as:
– T: “What should I think of first when I
think about nuclear division?”
– SS: “There are four phases: the
prophase, metaphase, anaphase and
telophase – in that order.”
– T: “OK. And tell me what happens in
the prophase and, by the way, how do
I know it is the first phase – what in its
name tells me it is the first phase?"
– SS: " ... etc"
