2. Task: The Example of development from cognitive, afective, and
psikomotoric activities.
A. Name of activity : Determining high of an object or building
with certain distance and angle of elevasi
Equipment : Klinometer
Steps of activity :
1. Students divided into group, every group consist of three student.
2. Klinometer made of degree of bow, hollow pipe, yarn, and
pendulum. So every group must prepare that equipments. And then
all the equipments stringed up to become klinometer by them.
(with tuition teacher)
3. With use klinometer, every group ordered to measure of highly
building or tree in school environment with angle of elevasi view
has been determined by group so also with distance, that is
perception distance with object or the first of perception distance
or second of perception distance.
4. Every group ordered to calculate of highly objects which they have
measured angle of elevasi and its distance
5. Every group ordered to presenting result of measurement of them
and enumeration in the following tables.
No Material noun Angle of the first Angle of the first Distance High
perception (α) perception (β) (d) (h)
3. 6. Every group ordered to made report about their activity to
determining high of an object or building with certain distance and
angle of elevasi.
SKILL DEVELOPMENT of Case A:
a. The Value of cognitive development
From activity above, we can see the value of cognitive
development student in understanding of Trigonometry material,
so student can make a calculating by a klinometers to find a high
of thing. And then, we can see from using formulas, the way of
find solution in their work, their opinions to do their work and
finally they are succes to find calculating of their work and
understand about trigonometry material.
b. The Value of afective development
We can see The Value of afective development in this activity at
their team work, cohesive of student in a group, divided work of
every student, then attitude of student to say their opinions, the
way of student to associate with their friend in group and the
other groups, attitude of student to ask something to their
teacher, and the other.
c. The Value of psikomotoric development
We can see The Value of psikomotoric development at how to use
klinometers, choosing tool will be used in process to find high of a
three or a thing, and then how to measure elevation angel and
distance a three or a thing.
4. B. Name of Activity : To find the area of sphere’s surface
Equipment :
1. Orange (bali’s orange)
2. Ribbon
3. Knife
4. Ruler
5. Paper
6. Compass
7. calculator
Steps of Activity :
1. Students divided into groups, and every group consist three
members
2. Teacher ordered every group to cut bali’s orange be two pair with
equal side
3. Measure the diameter of bali’s orange
4. Find the circumference of your orange with the ribbon. Be
accurate.
5. Using this measurement to find the radius of the sphere.
6. Draw two circles which diameter equal with other,
diameter of circle = diameter of bali’s orange
7. Remove the skin of bali’s orange and then cut to be little pieces
from the half of sphere.
8. Patch the little pieces to the draw of circle (point of 7). Then the
pieces bali’s orange will be provide a cover of all surface two
circle.
9. Then students must be proof with formulas that the surface area of
sphere is four area of circle.
10. Every group ordered to collect the result of experiment above !
5. SKILL DEVELOPMENT of Case B :
a. The Value of cognitive development
From the activity above, we can see the value of cognitive
development students such as, students can approximately that
the skin of bali’s orange can to find the surface area of sphere,
the using of sphere formulas and circles formulas to proof that the
surface area of sphere is four area of circle. And we can see from
calculating to proof the formulas. The other side, we can know
the cognitive development from step by step in process finishing
their work
b. The Value of afective development
The students can feel glad because they work, study and think
together with their friends so they are not stress and be happy
always. And then we can see from their team work, honesty at
measure the radius of bali’s orange, objective, attitude with
teacher and the other, efficiency of the using experiment tool.
c. The Value of psikomotoric development
The psikomotoric development students seen from how to the
cutting of bali’s orange, and then from the way patch the little
pieces to the draw of circle. And then from the cleaning of their
experiment. the other side, we can see from the structure of the
experiment tool.
