National exam becomes the hot topic in most of discussions. Though the Supreme Court has rejected an appeal by the go-vernment on the organization of the national exams, the controversy over whether it is necessary to maintain the national exams (UN) has continued. Some debates include the primary questions such as; does the quality of Indonesia education depend on the national exam?, will the quality of the Indonesian education system worsen without natipnal exam?
People, who support the national exam explain that the quality of the Indonesia education system will drop without the national exam, so they try to defend the current system.
However there are people who disagree with the opinion. Those who against this national exam kept in our high school education say that it doesn't need the national exams because the quality of education does not just depend on the national exam. Further, the national exam only measures a small portion of students' competence in specific subjects, and does not measure students' competences throughout the semester.
In fact, the national examination can still be useful as an instrument to evaluate or detect the level of students' cognitive competence in several subjects, on a national scale.
A kite is an object which is made from a light material stretched over a frame. Due to its light material a kite will lift off the ground and fly when it is tilted into the wind.
A kite is uses wind to make it fly because it is heavier than air. When wind travels over the surface of the kite, it is split into two streams of air. One stream of the air goes over the kite while the second stream goes under the kite.
The upper stream creates an area of low pressure above the kite. The lower stream hits the kite at a shallow angle and creates an area of high pressure.
The high pressure area has a pushing effect while the low pressure area has a pulling effect. The combination of push and pull can creates enough force to lift the kite into the air.
Kites have been known for thousand of years. They are used for military or scientific purposes. Todays kites are much used for leisure and competition.
