Research on the Reform and Practice of the "Three Teachings" in IoT Dual High-Standard Professional Group Based on the PAD Class Model

The PAD Class Model, proposed by Professor Zhang Xuexin of Fudan University in 2014, is an innovative teaching methodology. Its core lies in dividing classroom time into two halves, with one half dedicated to teachers imparting knowledge and the other half left for students to engage in interactive discussion and learning. Given the characteristics of the IoT Dual High-Standard Professional Group, such as interdisciplinary nature, practical orientation, innovative thinking, and team collaboration, as well as the practical need for the "Three Teachings" reform outlined in the "Vocational Education 20 Guidelines ", this study focuses primarily on teaching methodology reform, complemented by reforms in teaching materials and teachers. The PAD Class Model was applied to the "Computer Networks" course. The practical results show that this teaching model significantly improves classroom effectiveness and achieves remarkable outcomes in promoting the "Three Teachings" reform, providing new ideas and directions for education and teaching in the IoT Dual High-Standard Professional Group.
