Preview Generation for Mathematical Interactive Educational Resources in Netpad

With the development of network technology, some online educational resource platforms have emerged, and the number of resources on these platforms is increasing. How to preview resources is becoming increasingly crucial for users to understand the content of resources and retrieve resources efficiently. NetPad is a dynamic geometric resource platform, the resources on the platform have distinctive characteristics. We need to interact with it to understand the content of interactive dynamic resources, but the cost of performing this manual interactive process is relatively high. In this paper, we propose a method for generating picture preview of mathematical interactive educational resources. Firstly, we analyze the JSON file that stores interactive resource information, obtain interactive element information, and generate an operation sequence. Secondly, we execute the operation sequence using script software to simulate the interaction process between the user and the resource, and save the screenshots in the process to generate picture preview of interactive educational resources. Experimental results indicate that the method can effectively simulate the interactive process, and the generated picture preview is of great help to the user to understand the content of interactive educational resources.
