Problem Solving Skill (PSS) and Self-Regulated Learning (SRL) were still low, especially in the Calculus course, so a learning model is needed is to activated students to asking questions and to solve the problems well. The objective of the research was to analyze the validity of the STEM-oriented Problem Posing model (SPACE) which could improve PSA and SRL in Calculus courses. The research method used descriptive methods use Aitken-V to validate SPACE model by expert. Based on the results of the preliminary research show that Calculus learning should emphasized students involvement through some activities. Next at Prototyping phase obtained the abbreviated syntax namely SPACE (simulation, Posing, Action, Communication, Evaluation), social system, reaction principle, support system, instructional impact and accompaniment which were designed to follow the steps of the SPACE model. Based on results of the expert validation were obtained the SPACE model is valid. This can be seen from the criteria for the validity of the V-Aitken value above 0.4. The conclusion is each aspect in the model book, lecturer manual, and student guidebook that were in the valid criteria, so that the model can be used for learning Calculus. © 2024 Author(s).
