Purpose This study aims to analyse how first-year undergraduate audiovisual communication students assess the credibility and reliability of information on Wikipedia in Basque and analyse whether the experience of being a Wikipedia editor helps to improve students’ perceptions of Wikipedia’s trustworthiness. The purpose of this project was to help students to better understand the credibility mechanisms of Wikipedia in Basque regarding the work of editing and creating entries. Do students’ perceptions about how reliable Wikipedia is change if they receive training (...) as Wikipedia content editors and understand Wikipedia’s credibility mechanisms? What are their perceptions about the credibility of Wikipedia? Design/methodology/approach The authors observed and analysed students’ behaviour and perceptions when creating Wikipedia articles and learning about the process of evaluating Wikipedia. This research was carried out at [masked for review] over four consecutive years, where 188 students in the Degree Programme in Audiovisual Communication participated through a questionnaire and in-depth interviews. Findings After the experience of creating content on Wikipedia and learning about Wikipedia’s credibility mechanisms experientially, the majority of students reported that their perception of Wikipedia’s credibility had increased, and 70% of students believed Wikipedia to be reliable or more reliable than expected. A smaller number of students stated that understanding Wikipedia’s editing processes decreased their perception of Wikipedia’s credibility. Practical implications This project will lead to a better understanding of the performance of students in editing content on Wikipedia and of the impact that this editing experience has on students’ perceptions of credibility with respect to Wikipedia. It will make it possible to better incorporate Wikipedia content editing into the learning processes of students and citizens. This study provides interesting keys to improving the reliability and credibility of Wikipedia among students. Social implications As the study examined Basque Wikipedia, it has important social implications since Basque is a minority language and Wikipedia is the main sources of information for students who study in Basque. Originality/value The authors have been analysing the credibility of information in general and that of information on Wikipedia in particular since 2010. Based on this experience, the authors decided to design this study so that it was carried out while the students were creating and editing Wikipedia content as part of a project in their educational curriculum. Furthermore, the study expands the body of research carried out to date by incorporating the perspectives of media studies students. (shrink)
