Anatomy is a crucial aspect of biological sciences and medical education, playing a pivotal role in various clinical practices. To enhance the existing curriculum and improve students' spatial understanding of anatomy, educators have explored the use of moulages. In a groundbreaking study conducted in 2022-2023, the effectiveness of megamoulages in enhancing the comprehensive understanding of anatomy among medical students at Gonabad and Kurdistan University of Medical Sciences was thoroughly assessed. The produced megamoulages are not simply larger than conventional moulages; rather, they present anatomical details more clearly, including maximum anatomical points, structures, and neuro-vascular relationships as described in reference books and articles, which were not adequately represented in previous models, and they are also hand-painted.
The production of megamoulages involved a comprehensive 20-month sequential process. Initially, a needs assessment questionnaire was administered to medical students, residents, medical faculty surgeons, and anatomists to evaluate the project's feasibility and significance. Results revealed that the majority of respondents (88%) believed the production of megamoulages would facilitate anatomy education. Anatomical models were strategically selected based on their complexity and the unavailability of similar models from foreign companies. Megamoulages (two groups of megamoulages: the first includes unique models, such as a sectional megamoulage of the brainstem that displays all structures in detail, while the second group (cerebellum and mandible) as improved quality models, which are similar to existing ones) were designed using 3D software, printed in sections, and assembled with magnets. The completed moulages were subjected to thorough evaluations following Kirkpatrick's model, which included methods such as smile sheets and scientific tests administered to randomly divided third-semester medical students in the mentioned universities.
In both universities, student satisfaction with the use of megamoulages was significantly higher compared to conventional moulages (P < 0.05). Additionally, in a written test, students who utilized megamoulages achieved an average score that was about 2.73 points higher than those who used conventional moulages (P < 0.05).
The implementation of megamoulages significantly enhanced the scores of anatomy learners. This study underscores the importance of innovative teaching tools, such as megamoulages, in improving anatomical education and increasing student satisfaction.
解剖学是生物科学和医学教育的关键组成部分，在各种临床实践中发挥着核心作用。为了改进现有课程并提高学生对解剖学的空间理解，教育工作者探索了使用人体模型的方法。在2022 - 2023年进行的一项开创性研究中，对巨型人体模型在增强加兹阿巴德医科大学和库尔德医科大学医学生对解剖学的全面理解方面的有效性进行了全面评估。制作的巨型人体模型不仅仅比传统人体模型大；相反，它们更清晰地呈现了解剖学细节，包括参考书籍和文章中描述的最大解剖学要点、结构以及神经血管关系，这些在以前的模型中没有得到充分体现，而且它们还是手绘的。
巨型人体模型的制作涉及一个为期20个月的全面连续过程。最初，向医学生、住院医师、医学系外科医生和解剖学家发放了一份需求评估问卷，以评估该项目的可行性和重要性。结果显示，大多数受访者（88%）认为制作巨型人体模型将有助于解剖学教育。根据解剖模型的复杂性以及外国公司没有类似模型的情况进行了策略性选择。使用3D软件设计巨型人体模型（两组巨型人体模型：第一组包括独特的模型，如脑干的断层巨型人体模型，详细展示了所有结构，而第二组（小脑和下颌骨）作为质量改进模型，与现有模型相似），分部分打印并用磁铁组装。按照柯克帕特里克模型对完成的人体模型进行了全面评估，其中包括向上述大学随机分组的三年级医学生发放笑脸表和进行科学测试等方法。
在两所大学中，学生对使用巨型人体模型的满意度均显著高于传统人体模型（P < 0.05）。此外，在一次笔试中，使用巨型人体模型的学生平均得分比使用传统人体模型的学生高出约2.73分（P < 0.05）。
巨型人体模型的实施显著提高了解剖学学习者的成绩。本研究强调了创新教学工具，如巨型人体模型，在改善解剖学教育和提高学生满意度方面的重要性。
