摘要：Abstract Video is a tool used for teacher reflection and teacher training. Hence video analysis supports the reflection and enhance of one's own teaching. There are scientific studies that evidence the use of video for reflection. However, there is little research on video- annotation tool in teacher education. The purpose of this paper is to determine how many scientific studies research the use of video annotations tools in teacher training. Thus, we review different papers of national and international databases. We compare and contrast studies of video annotation tools over time and articles indexing in databases. Findings indicate the evolution of the number of studies in this research area observable in the five last years. Finally, it is necessary to encourage scientific community to inquiry in this research field.
