The improvement of strategies for information-based educational and teaching abilities of newly appointed teachers should be substantially investigated urgently based on the policy level of various countries or the reality of colleges and universities. However, from the perspective of the Technological Pedagogical Content Knowledge(TPACK)hierarchy, there are only a few studies on the strategies to improve the information-based educational and teaching abilities of newly appointed teachers. Therefore, this study analyzed the relationships between the three cores and four composite elements, designed the ability improvement strategy corresponding to each element, designed a hierarchical improving strategy which corresponds to 20 training contents, and used quasi-experimental research methods to apply the strategy to the 2019 newly recruited teacher training system of Guangdong University of Finance and Economics. Through the implementation of the training strategy for one semester and effect evaluation, combined with the comparative analysis of the training evaluation data of newly appointed teachers who did not implement this strategy in 2018, it shows that the implementation of the strategy can significantly improve the information-based educational and teaching ability of newly appointed teachers, with good results.
