传统实验虽然设计巧妙,器材简单,但是精度不高,误差较大,数据处理不便,实验的成功率也不高,效果不理想,影响了分析数据、得到结论、评价和反思过程的开展.基于各类传感器的数字实验大大拓展了实验手段,使得实验高效、精确、可信.本文以具体的探究实验为例,谈谈数字实验在数据采集、数据分析、辅助探究等方面的重要作用.一、数字实验实现数据精准快速采集数字实验提供了一系列的传感器,以力学为例,主要有光电门传感器,位移传感器和力传感器.由于传感器精度高、速度快,适合在课堂中有限时间内得到大量有效数据.下面以"探究作用力和反作用力关
Although the traditional experiment is cleverly designed and the equipment is simple, the accuracy is not high, the error is large, the data processing is inconvenient, the success rate of the experiment is not high, the result is not satisfactory, which affects the analysis of the data and the conclusion, evaluation and reflection process are carried out. Experiments on various sensors have greatly expanded the experimental methods, making the experiment efficient, accurate and credible.This paper takes a specific exploration experiment as an example to discuss the important role of digital experiments in data acquisition, data analysis and auxiliary investigation. , Digital experiments to achieve rapid and accurate data acquisition Digital experiments provide a series of sensors, to mechanics, for example, there are photoelectric door sensors, displacement sensors and force sensors.As the sensor high precision, fast, suitable for a limited time in the classroom A lot of valid data below to explore the role of force and reactionary
