Purpose The purpose of this paper is to analyze the new collaborative learning methods and tools used by elite FIFA referee technical instructors, referees and assistant referees to master the Laws of the Game. These tools allow instructors to learn through practical exercises off the field of play, while they carry out activities in a participative context in which they can share and improve their knowledge regarding the Laws of the Game and consequently the interpretations and the considerations soccer referees throughout the world use to make decisions on the field of play. Design/methodology/approach In this work, we assess a collaborative learning experience that took place during the annual FIFA FUTURO III courses that FIFA provided to FIFA referee technical instructors from its six confederations between 2013 and 2015, where 48 referee technical instructors selected from 211 national associations participated. These instructors constitute the elite of FIFA’s professional training and development chain. They teach other referee technical instructors who will then instruct international referees and assistant referees all over the world with the aim of achieving uniformity when applying the Laws of the Game. Findings The course participants showed a high degree of satisfaction with respect to these materials and methods, especially regarding the possibilities they offer for organizing group discussions and for “learning by doing,” and a lack of skills in ICT management has been detected for some participants, who have shown a willingness and interest to improve their skills in this field. Research limitations/implications The training and education of soccer referees is one of the most heterogeneous training processes in the world. This complex task is even more difficult because of the growing demand for video technology in referee decision making where successful teamwork requires a high level of communication and agreement among its members. Practical implications With 211 associations, FIFA is one of the largest organizations in the world. In international competitions such as the FIFA World Cup, the referees’ decisions are analyzed by media, thousands of fans and millions of viewers. Preparing new professionals for match analysis, interpretation of Laws of the Game and working in a team is a priority for FIFA and the world of soccer. Originality/value It is the first time that collaborative learning methods are used with interactive multimedia tools that facilitate collaborative work in the training environment of soccer referee instructors, international soccer referees and assistant referees. This paper establishes a basis and a reference for future research on the effectiveness of the new collaborative technologies used by FIFA for the training of international referees and assistant referees in general.

The virtual modification of the appearance of an object using lighting technologies has become very important in recent years, since the projection of light on an object allows us to alter its appearance in a virtual and reversible way. Considering the limitation of non-contact when analysing a work of art, these optical techniques have been used in fields of restoration of cultural heritage, allowing us to visualize the work as it was conceived by its author, after a process of acquisition and treatment of the image. Furthermore, the technique of altering the appearance of objects through the projection of light has been used in projects with artistic or even educational purposes. This review has treated the main studies of light projection as a technique to alter the appearance of objects, emphasizing the calibration methods used in each study, taking into account the importance of a correct calibration between devices to carry out this technology. In addition, since the described technique consists of projecting light, and one of the applications is related to cultural heritage, those studies that carry out the design and optimization of lighting systems will be described for a correct appreciation of the works of art, without altering its state of conservation.

The main objective of this article was to analyse whether the Interactive Video Test (IVT) is a useful tool for the practical off-field training of soccer assistant referees, and if its use could reduce erroneous on-field decisions when applying Law 11 of the Laws of the Game. Assistant referees were taken from the Spanish 2nd “B” and 3rd Divisions, and were divided into two groups, the Experimental Group (EG) and the Control Group (CG). The referees in the EG were trained with the Interactive Video Test by analysing 720 off-side decisions. Subsequently, both groups were assessed in on-field tests involving the simulation of 326 possible off-side situations. When the results of both groups were compared, there was a continuous improvement over time in the EG associated to the use of the IVT, significantly better than the improvement of the CG. Moreover, the IVT proved to be a good diagnostic tool to assess the skills of assistant referees in perceiving and evaluating off-side situations.
