This study aimed to identify the need for developing a model to enhance language teachers' learning management skills in the Thai context by integrating TPACK, PBL, CBL, and CLIL. It also focused on designing the model and testing its effectiveness. The participants included 390 language teachers for the needs analysis, 5 language education experts for model evaluation, and 30 language teachers for the model implementation phase. Data were collected through needs analysis questionnaires, a proposed model for learning management skills, evaluation forms, satisfaction surveys, and interviews. The data were analyzed using the PNI-modified method for needs assessment and descriptive statistics for evaluating the model. The findings indicated that the model significantly improved teachers' learning management skills, and participants expressed high satisfaction with its implementation. This study contributes to teacher development by integrating essential pedagogical approaches to improve language teaching practices. (c) 2025 The Authors. Published by IASE.
