Construction of a Task-Driven Model for BIM Course Cost Training Based on OBE Concept

Traditional Building Information Modeling cost estimation training often suffers from fragmented task design, weak linkage between skills and knowledge, and unbalanced assessment mechanisms, resulting in inefficient learning and insufficient competency formation. To address these problems, this study develops a task-driven training model grounded in the Outcome-Based Education philosophy. The model integrates task decomposition, knowledge–skill mapping, and closed-loop feedback, constructing a dynamic and data-driven learning process that continuously aligns performance indicators with instructional goals.Using data from 56 students in a comprehensive BIM cost estimation course, experimental results show significant improvements: task completion rate increased by 10.0%, knowledge mastery by 12.4%, feedback response time reduced by 42.6%, and learning engagement enhanced by 18.1% compared with traditional teaching. These findings verify the model’s effectiveness in strengthening precision, collaboration, and adaptability. The study offers a replicable framework for intelligent, measurable, and outcome-oriented BIM education within engineering training.
