论文摘要
我们基于\ textit {textit {最新的技术}技术，向我们的学生提供了一项自制的实验活动，该活动成功地向我们的学生提议，以教授科学和工程专业的学生的错误分析和不确定性。在过去的十年中，智能手机的出现严重影响了我们的日常生活。多亏了它们的内置传感器，这项革命在许多领域，尤其是教育领域都受到了影响。在这里，我们展示了如何使用智能手机传感器来教授科学专业的学生（例如任何测量）的基本概念，除非指定置信区间或如何确定结果是否与模型一致，否则从已经知道的其他人那里辨别出新现象。我们解释了如何获得和分析实验波动并与高斯分布进行讨论。在另一个应用程序中，我们展示了如何确定最佳测量值，这是标准误差的函数和给定传感器的数字分辨率的函数。
We present a home-lab experimental activity, successfully proposed to our students during covid19 pandemic, based on \textit{state-of-the-art} technologies to teach error analysis and uncertainties to science and engineering students. In the last decade the appearance of smartphones considerably affected our daily life. Thanks to their built-in sensors, this revolution has impacted in many areas and, in particular, the educational field. Here we show how to use smartphone sensors to teach fundamental concepts for science students such as any measurement is useless unless a confidence interval is specified or how to determine if a result agrees with a model, or to discern a new phenomenon from others already known. We explain how to obtain and analyse experimental fluctuations and discuss in relation with the Gaussian distribution. In another application we show how to determine the optimal number of measurements as a function of the standard error and the digital resolution of a given sensor.
