| 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
