The traditional approach of e-learning platforms based on learning management systems has allowed education to be accessible to a broader group of people; however, their pedagogical model based on promoting a transmissive approach has caused learning outcomes do not achieve the success of their traditional counterpart. There is a disconnection between what happens in the physical classroom and what happens when students take an online class. The experience usually goes from interactive to static.In this work, we propose the design of an interactive e-learning platform that makes use of dynamic media such as videos, to improve the interactive experience of students. To this end, the main limitations of current systems are studied and different solutions are proposed to mitigate the problems. The main contributions of this work are, first, to establish a set of challenges that interactive e-learning platforms should support, and second, the description of the necessary processes to implement the platform.

Cone Beam Computed Tomographs (CBCT) provide high-quality 3D images with submillimeter resolutions, fairly short scantimes (10 to 70 seconds) and radiation doses up to 15 times lower than classic CT systems. Thanks to this, its use in differentareas, both in dentistry and in other areas, has increased significantly. Additionally, the advancement of teleradiology and thecompatibility of the resulting DICOM images with different types of planning, simulation and 3D printing software; have madeit possible to consolidate a powerful tool for the possible early and accurate diagnosis of different deep lesions, anomalies andthe acquisition of deep knowledge about a specific maxillofacial area and its relationship with adjacent structures. However,its resulting measurements with very little error range and the possibility of generating three-dimensional reconstructionsmake it a clear pedagogical instrument of great utility in modern archaeological, technological, forensic, anthropologicaland biomedical investigation techniques. This article provides an overview of CBCT systems, their associated computationaltechnologies, and demonstrates their applicability as tools for the analysis, preservation, reconstruction and reproduction ofarchaeological pieces. As a test, its application in the acquisition of different stereolithographic models of archaeologicalremains of the Pumapungo Museum in the city of Cuenca, Ecuador is described
