This research examines the effect of the blended project-based learning (PjBL) model and creative thinking ability on engineering students' drawing learning outcomes. Using a pre and post-test quasi-experimental design, the research included a sample of 80 students from two different classes at the Faculty of Engineering, UNIMED, North Sumatra, Indonesia. The data were analyzed using descriptive and inferential statistics through two-way ANOVA. Subsequently, the results showed that the members of experimental group I, comprising students who participated in the blended PjBL model, obtained the highest engineering drawing learning outcomes. The creative thinking ability outcomes of the students taught with this model were higher than those of the group II students who used the ordinary blended learning model. However, those with low thinking abilities taught with the ordinary model exhibited higher learning outcomes than the experimental group. These results show an interaction between the effect of the PjBL model and creative thinking ability on the learning outcomes of engineering students. Therefore, lecturers need to use a blended PjBL model to ensure improved outcomes, alongside enhancing students' creative thinking abilities to increase the model's effectiveness.
