Compared with top-notch special training, Jiangsu second-grade mathematics teaching assistant problem-solving experts are better. Teaching assistant problem-solving experts are equivalent to synchronous training, and it is not difficult to deepen the content of teaching materials. Top-notch special training is more difficult on the basis of the original work, and it is more difficult for children to write, which will cause children to be frustrated. Therefore, I personally think that instead of putting so much pressure on children, it is better to choose teaching assistants to solve problems.
