Liang's team developed a product that is a supplement to the science textbooks with coursework, resources and teaching aids that follow the standard.

"Science has become a compulsory course in elementary schools now, which means the government is paying more and more attention to scientific innovation. Therefore, it's important to teach the children correctly, as it's their first chance to learn about the sciences," he says.

On the other hand, Liang says, the number of science teachers working in elementary schools is not enough, noting that some of them are only part-time, so "we want to help them with more teaching materials and a way to focus on how to make science more interesting".
