Topic One
Developing the tasks for the mathematical
problem solving or mathematical
modeling on the situations of the
Earthquake or Tsunami for each school
level.
Possible Learning Content
A Knowledge of why and how Earthquake and
Tsunmai happen
B Models related to Earthquake and Tsunmai
(mathematics and physical model)
C Prevention and damage control (Good Building
and Logistic arrangement)
D After the disaster (Relief Work and its
arrangement)
A Knowledge of why and how
Earthquake and Tsunmai happen
Geography (plate theory)
Data (frequency of earthquake and Tsunmai)
Possible prediction method and warning system
B Models related to
Earthquake and Tsunmai
•
•
•
•
•
Magnitude of Quake (calculation and
energy level)
P wave and S wave
Longitudinal wave and Vertical wave
Time lapse between the P-wave and Swave. (r/v1 – r/v2)
Safe space during shock (triangular
shape)
B Models related to
Earthquake and Tsunmai
•
•
•
•
•
•
Volume of water (formed by thrust, a
constant after thrust in a certain time)
Wave and energy (measurement)
Travelling time of wave
Successive waves (time lapsed)
Height of Tsunmai (deep vs shallow)
Calculation of possible energy (1/r^2)
C Prevention and damage control
(Good Building and Logistic arrangement)
•
•
•
Knowledge on land used and housing
development
Building of safe haven (high community
hall near the shore)
Effective anouncement systeem
(communication)
D After the disaster
(Relief Work and its arrangement)
•
•
•
Estimation on demand of essential
resources
Effective distribution system (multiple
centre vs central centre) and
transportation system
Requirement of a Relief Centre
Topic Two
Status,
experience and
plan of lesson study in Hong Kong
Topic Two (Status)
•
•
•
•
HK is lucky (we have no earthquake no
tsunmai, no flood, no volcano)
We do have typhoon
mathematics curriculum in Hong Kong is
centralized
curriculum does not cover any part of
modeling
Topic Two (Expeience)
•
•
School Base Learning
Cross curriculum approach
Topic Two (plan of Lesson Study)
•
•
•
•
•
Research into the content material
Develop Curriculum
Cross curriculum approach
Modelling for the high school
Relief work planning/estimation for
primary school
