Abstract: Based on the demand for talents in the development of mineral resources exploration and exploitation, the direction of geoscience instrument combined with its own scientific research advantages, explored the mixed practical teaching path of "ladder-type research feedback" and "online and offline". Based on the scientific research achievements of "ECUTRES-III 3D Resistivity Imaging System" and according to the learning ability of undergraduate students at different stages, the four-layer step-by-step cultivation of "basic cognition-systematic training-field combat-social expansion" was implemented. Integrating "online and offline" teaching methods, it built a practice platform of "thinking-learning-doing-using" for students. The practical results show that the model can effectively promote the scientific research feedback in teaching, and provide experience and reference for the cultivation of innovative and applied talents in the new era.

Key words: Geoscience instrument, Ladder-type, Research feedback, Online and offline
