民族地区中学物理教学中使用低成本实验有三种主要途径,即低成本实验应用于演示实验、学生随堂实验和课外实验。低成本实验有助于解决民族地区中学物理教学中实验仪器匮乏的问题,且低成本实验本身具有潜在的深层教育价值和教育功能,有助于学生的发展。 There are three main ways to use low-cost experiment in middle school physics teaching in minority areas. That is, low-cost experiment is applied to demonstration experiment, pupil’s pupil experiment and extra-curricular experiment. Low-cost experiments help to solve the problem of lack of experimental apparatus in physics teaching in middle schools in ethnic minority areas, and the low-cost experiments themselves have potential deep educational value and educational function, which is helpful to the students’ development.
