Discussion of the Experimental Teaching of the Hall Effect

Discovery process and the development of Hall Effect are briefly introduced. A discussion is done to find out about how to cultivate students' innovative thinking through the teaching of Hall Effect. Through the derivation of the actual calculation formula of Hall voltage on Hall Effect experiment, the function of the “symmetry measuring method” in eliminating the error of the experimental system is also put under examination. By such a means, the students' idea of scientific methodology can be expected to take shape. This is of practical significance for developing students' scientific quality in the teaching of College Physics experiment.
