Abstract: This paper has studied the teaching design of heat conduction in multilayered medium by a group of experimental data of prosthetic body in high temperature. This paper has designed sub-problems that are logically progressing, in the process of modeling the definite problem of heat conduction in multilayer protective clothing, also in the solution process of the model based on finite difference algorithm. The students are guided to explore the experimental data more deeply through pondering these problems, thereby achieving the target of decomposing and refining the research process in an effective way.
