| Background
: |
Many
students have problems in understanding the process
of cell division. An interesting teaching and
learning process such as constructing models and
hands on projects can help them.This model/kit
consist of the following items:
- Materials
to construct model
- Instructional
cards (5 pieces)
- Example
model with a list of structures to be labelled
is provided along with a brief description of
the structures.
- All
materials and instructions are placed in a compartmentalised
box.
|
| Objectives
: |
At
the end of teaching and learning process, the
students will be able to
-
work as a team in constructing the model
- understand
the concept and significance of the process
in living cells and organisms
- remember
and explain every phase of mitosis
|
| Benefits
for teaching- learning process: |
- The
kit can be used in the first topic of Biology
Form 4 syllabus and Science Form 4
- Learning
process is more on inquiry and discovery, to
enhance their interest.
- To
create their thinking skills and creativity
- Can
be used as teaching aids for outdoor activity
|
| Apparatus
/ Material : |
Materials
to construct model (7-P1):
-
Manila card/paper plates
- Threads
of different colours and thickness
- Beads
Instructional
cards (5 pieces) (7-P2):
-
Each card will consist of information and directions
(for students) regarding a phase in mitosis
- Information
includes the structure and position of the chromosomes,
nucleus membrane, spindle fibbers, centrioles
and other information relevant to visualise
the cell
- Cards
are numbered sequentially to the phases.
|
| Constructions
of teaching aids : |
- Materials
to construct model are prepared (7-P1).
- Instructional
cards with brief information are prepared for
students' references (7-P2 and 7-P3).
- A
complete model of a phase, without label, is
prepared for the students to label (7-P4b).
|
| Implemen-tations
: |
-
Students are divided into groups of a maximum
number of five.
- Each
group is given a complete set of kit.
- each group is to set up the model within
a given time, based on the information given
on the instructional cards using their understanding.
-
time allocated depends on
i.
whether the group is to set the model for
all or one of the phases
ii. the students' level of education
- Each
group is to construct the model in team or individually
based on information given on the instructional
cards.
- In
setting up the model, no references are allowed
and the students are not required to do any
prior reading. Thus, stimulating their thinking
process and prodding their creativity.
- Each
phase of the model is arranged in a sequence
on a board (or a flat surface (7-P4a).
- Students
give a brief explanation of the process in a
report or presentation.
- Students
will also do the labelling of the model cell
(7-P4b).
- The
teacher will supervise the groups and give necessary
comments to reinforce their understanding of
the process after the report or presentation.
- Making
the task in a competition form will create a
lively and competitive atmosphere.

| Suggestion
for modification : |
- The
same method can be used to construct a meiosis
model
- Then,
the comparison for both process can be list
out
- The
significance of mitosis and meiosis can be relate
to certain examples in heredity
