Problems solved by technology

[0002] In middle school physics course teaching, many experiments about mechanics and electromagnetism will be involved. For example, a energized coil can generate a magnetic field, and the magnitude of the magnetic field is related to the magnitude of the current passing through the coil; The magnitude of the force is related to the magnitude and direction of the magnetic field; for example, the elongation of a spring within a certain range is proportional to the magnitude of the tension, etc. These experiments generally have corresponding experimental devices for verification, but only a simple conceptual understanding, The relationship between various physical quantities cannot be verified intuitively through data. At the same time, the experiments are relatively independent and lack of correlation. It cannot stimulate students' creative thinking and imagination well, and cannot make students understand the experiment accurately and quickly. and the existing experimental devices are generally multiple independent parts, but in classroom teaching, experimental demonstrations are required, or students operate in person, and the large number of experimental devices is inconvenient to carry and carry, which affects the quality of experimental teaching
