Learning objects are reusable teaching units that are supported by various learning management systems, such as Moodle and Blackboard. Once learning object standards are followed, several types of media can be used as learning objects, such as augmented reality applications. We propose the use of augmented reality content as media for e-learning systems. Therefore, this paper presents an Web Augmented Reality-based Authoring called WebAR. It is compatible with Experience API (xAPI) which is a standard learning object that is based on the Shareable Content Object Reference Model (SCORM). Learning objects based on augmented reality can also be used to assist students with difficulties related to spatial skills. Keywords: Augmented reality · Learning objects · E-learning 1 Introduction The use of technological resources in the teaching and learning process has grown in recent years. One of these resources is learning objects, which can be defined in general terms as a way to organize and structure digital educational materials. According to Wiley [18], learning objects include any digital resource that can be reused to support teaching and learning. Thus, learning objects can be characterized as different types of media, such as images, videos, graphics, and sounds. The use of learning objects to promote sharing content has been discussed in the context of e-learning [17], which can be defined as a way to deliver information and instruction to someone through the Internet.
