Accessible Simulation Approaches: The Effect of Portable Three-Dimensional Visual Material-Supported Education on University Students' Knowledge, Satisfaction, and Self-Confidence
This randomized controlled trial aimed to evaluate the effectiveness of simulation-based education supported by a portable and mobile three-dimensional (3D) visual material on university students' knowledge of cervical dilation assessment, learning satisfaction, self-confidence in learning, and perceptions of simulation design. Undergraduate health sciences students were randomly assigned to either an intervention group receiving simulation training with the portable 3D material in addition to standard education or a control group receiving standard education alone. The primary outcome was change in knowledge of cervical dilation assessment. Secondary outcomes included student satisfaction, self-confidence in learning, and perceptions of simulation design.
This study is a parallel-group, 1:1 allocation randomized controlled trial with a pretest-posttest design conducted among third-year undergraduate health sciences students enrolled in the Pregnancy and Care course. Participants were randomly assigned using a computer-generated randomization sequence with allocation concealment through sequentially numbered opaque sealed envelopes.
Both groups received the standard theoretical and laboratory curriculum on cervical dilation assessment. In addition, participants allocated to the intervention group received simulation-based training supported by a portable and foldable three-dimensional cervical dilation educational model designed to facilitate repeated individual practice outside the simulation laboratory. Students practiced with the model seven times throughout the semester using a standardized educational protocol delivered by the same instructor.
The educational material was specifically developed to provide an accessible, reusable, and portable simulation resource that allows repeated psychomotor practice without requiring permanent simulation laboratory access. The study evaluated whether supplementing standard education with repeated practice using the portable three-dimensional model improves educational outcomes compared with standard education alone. The trial was conducted in accordance with the CONSORT reporting guideline, and no protocol modifications were made after trial initiation. Ethical approval and written informed consent were obtained before participant enrollment.
