For Sec 3 Geography Elective

1. Geog Homework -
Evaluation

2. You will need
- Pg 13-16 of your coastal handout (given on
Thursday)
- Your textbook

3. Lesson Objectives
By the end of this lesson, you will be able to
- Explain what evaluation involves
- Describe the different components of
evaluation
- Evaluate the effectiveness of gabions in
protecting a coast from erosion.

4. evaluate
/ih-val-yoo-eyt/
To judge the value of something

5. As profound as the term sounds...
we have been
evaluating
everyday!

6. Examples of day-to-day evaluation:
Which is the best
Handphone model?
Is that movie good?
Which subject is the
easiest to score?
Should we go for
KFC or McDonalds
today?
Which canteen store is
better?

7. what do we do when we
evaluate?
- compare and weigh which is better
- decide what is the worth of something

8. how do we
evaluate?

9. how do we
evaluate?
The next slide is a movie review of “The
Hunger Games”, which is an example of
evaluation.
Determine what must one do when they
evaluate.

10. Set in the future, 16-year-old Katniss Everdeen is living with her mother and
little sister in what's left of North America, in one of 12 districts all being run
by the Capitol. Despite mastering the skill of hunting and trapping edible
plants, Katniss still struggles to keep her family from going hungry.
Each year, the names of all residents between the ages of 12 and 18 are
entered into a lottery and two names, one girl and one boy, are chosen at
random from each district to compete in the televised Hunger Games. The
24 children must try to kill each other off and the last one standing is
rewarded by the Capitol with a feast of food. When her little sister's name is
selected, Katniss steps up to take her place in the deadly competition.
I can say that this was a must-see movie of the year. Scenery was accurate
to the book and it was good to see that the arena in which they fought was
as it was described.
I think one bad thing I wish they would have done was made the movie a
few minutes longer in order to display correct and actual events in the
book. Such as where the Mockingjay Pin came from, possibly explained
events in the movie better for those who haven't read the book.

86. Example 1:
How effective are gabions in preventing coastal erosion?
Gabions is an effective method to prevent coastal erosion.
Gabions are wired cages that contains rocks. They are stacked
along the coast to form a wall. Gabions are effective in
preventing coastal erosion because wave energy is absorbed as
the waves are forced through the narrow spaces in between the
rocks. As a result, ?? energy is available to erode the coast. For
example, in the 1970s, gabions was used in East Coast Park,
Singapore, to protect the coast from erosion.

87. Example 1:
How effective are gabions in preventing coastal erosion?
Gabions is an effective method to prevent coastal erosion.
Gabions are wired cages that contains rocks. They are stacked
along the coast to form a wall. Gabions are effective in
preventing coastal erosion because wave energy is absorbed as
the waves are forced through the narrow spaces in between the
rocks. As a result, less energy is available to erode the coast.
For example, in the 1970s, gabions was used in East Coast Park,
Singapore, to protect the coast from erosion.

88. Example 2:
How effective are gabions in preventing coastal erosion?
Gabions are effective in preventing coastal erosion because
wave energy is absorbed as the waves are forced through the
narrow spaces in between the rocks. As a result, less energy is
available to erode the coast. For example, in the 1970s, gabions
was used in East Coast Park, Singapore, to protect the coast
from erosion. Gabions are ineffective in preventing coastal
erosion because it is easily destroyed and require frequent
maintenance. As a result, it cannot protect the coast for a long
period of time from erosion. For example, the gabions used in
East Coast Park, Singapore, in the 1970s had to be replaced
after a few years as it was destroyed.

92. Example 4:
How effective are gabions in preventing coastal erosion?
Gabions is an effective method in preventing coastal erosion.
Gabions are wired cages that contains rocks. They are stacked

preventing coastal erosion because wave energy is absorbed as
the waves are forced through the narrow spaces in between the
rocks. As a result, less energy is available to erode the coast.
For example, in the 1970s, gabions was used in East Coast Park,
Singapore. Gabions are ugly and spoils the beauty of the beach.

94. recap

95. when we evaluate...
1) What the Factor is about
2) Explain why factor is good
(With Egs)
3) Explain why factor is bad (With
Egs)
We can modify the
square approach to help
us plan our answers

96. tips for better answers
1) Make sure your explanation answers the question.
Check that it consist of reaction and outcome to answe
r
the question.
2) Remember to show both good and bad
3) Make sure examples support the explanation.
In another words, if the explanation is saying that chicke
ns
are bad for health, you should provide an example that
shows that chickens are bad for health, not an example
to
show why chickens are delicious!
