The education about earthquakes
In 2005, Libarkin, J.C., and Anderson, S.W., 2
constructed a multiple-choice assessment
instrument for using in the Earth science called
GCI (The Geoscience Concept Inventory). These
test items cover topics related to general
physical geology concepts, as well as underlying
fundamental ideas in physics and chemistry, such
as gravity and radioactivity, these are integral
to understanding the conceptual Earth.
In 2003, C Fazio et al. 3 constructed an
activity-based teaching unit that aimed to
improve the understanding about properties of
seismic waves focusing on analyzing the
properties of very small earthquakes produced
through mechanical shock waves in slabs of
different materials.
12
The education about earthquakes in Thailand
Subtopics of earthquakes on the 6th strand of
science following foundation education
curriculum Buddhist Era 2544 (http//www.ipst.ac.t
h/sci_curriculum/)

• Causes of earthquakes
• The seismometer
• Seismic waves
• Mercalli and Richter scale
• Earthquakes in Thailand
• Safety procedures from earthquakes and Tsunami

13
Explore students understanding of earthquakes
after finishing the 6th strand of science by
means of traditional teaching.
14
Question Are zone of rainy countries more risky
to occur earthquakes
than that of dry countries? Why?
15
Question Which country Thailand or Japan that
has the most probability to occur
earthquakes? Why?
Others
Plate boundaries
Islands
Topography
Volcano eruption
16

• To determine high school students
  misunderstanding of earthquakes.
• To construct a novel teaching module for
  earthquakes (related to the cause of earthquakes
  and the principle of an earthquake detector).
• To increase students conceptual understanding of
  earthquakes by using a novel teaching module.

17

• What concepts of earthquakes do students
  misunderstanding?
• 2. What is a novel teaching module for
  earthquakes?
• 3. Does a novel teaching module increase high
  school students conceptual understanding of
  earthquakes?

1) The characteristics and cause of natural
earthquakes

• Most students believe that
• The amount of rain affect to earthquakes.
• All earthquakes create visible cracks on the
  Earth's surface.

21
2) The basic principle of seismometers

• Most students believe that
• Seismograms are used for measuring the magnitude
  of an earthquake, not for locating its epicenter.
  
• The mass of a seismometer will move when
  earthquakes occur.

22
3) The seismic wave velocity

• Most students believe that
• The seismic waves of the 8 Richter magnitude
  scale propagate faster than those of the
  magnitude 6 because of its violence and vibration.

23
4) The Richter magnitude scale

• Most students believe that
• The ratio of the ground vibration amplitude of 8
  Richter magnitude scale to that of 6 Richter
  magnitude scale is 21.
• A change of one magnitude on the Richter scale
  corresponds to a difference in released energy 10
  times.

24
4 Groups of the students misconceptions
1) The characteristics and cause of natural
earthquakes 2) The basic principle of
seismometers 3) The seismic wave velocity 4)
The Richter magnitude scale

26
To construct an active based teaching module on
the topic of earthquake.

• Seismograms

33
Activity 1 Locating the epicenter of an
earthquake
Purpose
To locate the epicenter of an earthquake by using
online seismograms.
Materials

• a rope
• 3 seismograms
• a pair of compasses
• a worksheet

34
1) Students discuss and share some idea for
finding the position of the gold by using the
three intersection point method.
35
2) Students use 3 seismograms to locate the
epicenter of an earthquake
36

The seismograms
43

• The main parts of seismometers and their
  properties.
• The recording earthquake signals.
• The characteristics of seismograms.
• Anatomy of a wave (amplitude, wave length,
  period, frequency, crest, trough).
• The relation between magnitudes of earthquakes
  and amplitudes of waves on seismograms.
• Anatomy of p waves, s waves and surface waves on
  seismograms.
