平板电脑被用作实验工具，记录和分析从移动的滑板上垂直抛出的球的运动。特殊应用程序逐分量绘制测量数据，允许简单地确定初始条件和g，以便探索基本的运动规律。这项实验可以很容易地由学生自己完成，在他们的问题解决过程中提供了比传统学习方法更多的自主性。我们认为，这种自主性和实验工具的真实性都促进了他们的动机。
Tablet computers were used as experimental tools to record and analyse the motion of a ball thrown vertically from a moving skateboard. Special applications plotted the measurement data component by component, allowing a simple determination of initial conditions and g in order to explore the underlying laws of motion. This experiment can easily be performed by students themselves, providing more autonomy in their problem-solving processes than traditional learning approaches. We believe that this autonomy and the authenticity of the experimental tool both foster their motivation.
