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)

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.

B. Name of Activity : To find the area of sphere’s surfaceEquipment : 1. Orange (bali’s orange) 2. Ribbon 3. Knife 4. Ruler 5. Paper 6. Compass 7. calculatorSteps 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 !

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 workb. 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.
