针对传统喷泉实验的不足,可将手持技术引入喷泉实验的设计之中,凭借压强传感器实时检测喷泉实验中压强的变化,即可让学生从数据的变化中感知压强的变化。其优点体现在,一方面可以加强学生的感知体验,促其从定量的角度认识喷泉实验的原理;另一方面教师可以利用手持技术辅助实验教学,能够让学生直观体验实验过程,并降低从形象实验事实到抽象实验原理的分析难度。
In view of the deficiency of the traditional fountain experiment, the hand-held technique can be introduced into the design of the fountain experiment. With the real-time detection of the pressure change in the fountain experiment by the pressure sensor, students can perceive the change of pressure from the change of the data. The advantages lie in: on the one hand, it can enhance the students’ perception experience and promote the principle of fountain experiment quantitatively; on the other hand, teachers can use the hand-held technique to assist the experimental teaching, enable the students to experience the experimental process intuitively, Experimental facts to the abstract experimental principle of the analysis of the difficulty.
