Fig. 1: Construction and Evaluation of the Teaching Plan Dataset.

This figure illustrates the process involving three main phases: dataset construction, quality enhancement, and effectiveness evaluation. During the dataset construction phase, four baseline teaching plan datasets (Datasets A, B, C, and G), comprising a total of 240 teaching plans, were created. In the quality enhancement phase, the process unfolded in three steps. First, the LLM simulated classroom interactions between teacher and students based on the content of the teaching plans. Second, the LLM generated teaching reflections by integrating the teaching plans with the simulated classroom interaction texts. Third, the LLM refined the teaching plans by incorporating the original plans and the generated teaching reflections. Four improved teaching plan datasets were obtained in this phase (Datasets D, E, F, and H), with 240 teaching plans in total. Finally, in the evaluation phase, manual assessment and comparative analysis were conducted on 8 teaching plan datasets.
