Results of the analysis of experimental methods conducted by science-gifted students.
Manipulated variable | Dependent variable | Experiment method | No. | Sub-sum |
Moving distance | Time | (A-1) the experiment which measure the period or frequency of the pendulum according to the target moving distance of the ball | 15 | 33 |
(A-2) the experiment which measure the change in the water clock according to the ball's target travel distance | 13 | |||
(A-3) the experiment which compare the position where the ball moved down the slope with the distance the ball rolled from the constant velocity motion device | 3 | |||
(A-4) the experiment which measure the change in the hourglass according to the ball's target travel distance | 2 | |||
Time | Moving distance | (B-1) the experiment which measure the moving distance of the ball on an inclined plane according to the period of the pendulum | 23 | 25 |
(B-2) the experiment which measure the distance a ball moves on a slope according to the change in a water clock | 2 | |||
