A 3D microfossil collection and its use in a remote micropaleontology practical work course

Résumé

Micropaleontology, a naturalist discipline relying heavily on observation and description, faces significant teaching challenges due to limited access to material resources, samples, and expertise. To address these constraints, we developed a free online undergraduate course in micropaleontology centered on a pedagogical collection of 136 numerically reconstructed 3D microfossils. The 3D models, acquired mainly via X-ray microcomputed tomography and other advanced imaging techniques, represent diverse taxonomic groups such as foraminifera, ostracods, coccolithophores, diatoms, and pollen. Hosted on the Sketchfab platform and integrated within the Moodle-based Unisciel learning management system, the course is structured into taxonomical chapters featuring learning texts, observation activities with annotated 3D models, and evaluation quizzes. Despite limitations including the absence of scale bars on embedded models and the relatively low diversity due to scanning costs and technical challenges, the course offers an innovative pedagogical approach combining remote access to interactive 3D microfossils with structured learning and continuous assessment. This resource aims to improve micropaleontology education by facilitating detailed morphological observation and taxonomic identification remotely, overcoming common barriers in traditional teaching settings. Preliminary feedback highlights the potential for blended learning adaptation and underscores the need for ongoing evaluation to optimize educational outcomes. The course and 3D collection serve as a foundation for further development of digital micropaleontology tools, promoting wider accessibility and fostering enhanced scientific training in Earth and Life Sciences.
