eLearning and Embryology: Designing an Application to Improve 3D Comprehension of Embryological Structures.

Area of Science:

• Histology
• Embryology
• Medical Education

Background:

• Embryology and histology present significant learning challenges for higher education students.
• Difficulties in visualizing 3D tissue orientation and limited lab access contribute to negative perceptions.
• Existing digital histology tools often lack effective 3D visualization capabilities.

Purpose of the Study:

• To develop and evaluate a novel 3D visualization tool for embryology and histology education.
• To address the challenges of 3D orientation comprehension in histology and embryology.
• To compare the efficacy of a 3D reconstruction mobile application against current eHistology programs.

Main Methods:

• Created 3D embryological reconstructions from serial histology sections of a sheep embryo.
• Developed a mobile application integrating 2D histology sections with interactive 3D models.
• Assessed the application's effectiveness with life sciences graduates using qualitative surveys and quantitative orientation tests.

Main Results:

• The 3D visualization modality significantly improved student comprehension of slide orientation compared to traditional methods (p=0.042).
• The developed mobile application was rated as more interesting, useful, and usable than existing eHistology tools (p<0.05).
• Participants demonstrated enhanced understanding of spatial relationships within histological specimens.

Conclusions:

• 3D reconstruction and visualization tools offer a more effective approach to learning challenging embryology and histology concepts.
• This technology has the potential to increase student engagement and improve learning outcomes in these fields.
• Mobile applications integrating 3D models can overcome limitations of traditional histology education.
