Abstract


This research is intended to detect the misconception about parabolic motion of the tenth grade students of SMA N 6 Pontianak. The test items are adapted from the diagnostic tests which have been developed and have also met the required criteria of Lila (2017). There are 24 items of diagnostic tests. The research simple consists of 36 students which are the tenth grade students of SMA N 6 Pontianak. The result shows that 58,33% students stated that the maximum speed is when an object is on the top; 27,78% students stated that the minimum speed is on the farthest point; 30,56% students stated that the smallest the elevation angle the more time is needed; 91,67% students stated that the largest the elevation angle the farthest an object can reach; 63,89% students stated that the speed of axis x is different from the initial speed; 75% students stated that the time need will be different when two object are dropped together on different tracks; 63,89% students stated that an object dropped at a certain height will form parabolic motion track which was seen by observer as a pilot; 55,56% students stated that an object dropped at a certain height will form a backward parabolic motion track seen by observer from the ground. Hopefully the findings of this research will be used as additional reference when choosing the right treatment to solve the misconception.
