Resumen:
In recent years, collective teacher efficacy has been presented as a promising factor in improving student performance (Donohoo, 2017; Eells, 2011; Hattie, 2016). However, unlike self-efficacy beliefs, collective teacher efficacy has been studied much less. Hence, this systematic literature mapping seeks to deepen the development and study of the collective efficacy beliefs of teachers in the academic field, with the objective of understanding and synthesizing the information of various investigations regarding the subject in question. Through the methodology of systematic mapping, a total of 60 potential studies published between 2000 and 2019 and indexed in the Scopus and Web of Science databases were found. After the application of the inclusion and exclusion criteria, 35 studies were included in the present investigation. The results show the geographical distribution of the studies, the most frequently cited articles, the variables related to collective teacher efficacy, the instruments used to evaluate these beliefs, and the educational levels in which they have been studied. There is a clear interest in the study regarding the impact of collective teacher efficacy on student learning and performance. However, there is a lack of research on this subject in Spanish-speaking countries, as well as research focused on the promotion and development of collective teacher efficacy. This study concludes with a proposal for future lines of research.
