This systematic review of the literature focuses on the empirical research conducted between 1998 and 2018 at the intersection of leaders, teachers, and technology in K-12 schools. The question guiding this review was "what does the technology integration literature identify as key leadership practices that support teachers' technology integration efforts?" Findings are presented in terms of the larger body of knowledge about effective leadership practices that are empirically shown to influence teaching and learning by applying a conceptual framework of empirically derived leadership practices. The researchers analyzed, deductively coded, and categorized findings from 34 relevant articles in peer-reviewed journals. Findings emphasized leadership practices for building professional capacity including providing teachers with opportunities to learn, creating communities of practice for them, considering their individualized needs, and addressing issues of access and support. In this article, domains of the conceptual framework are described and convey the findings about leadership practices in terms of IT and offer suggestions for further synthesizing the currently siloed work on technology integration in the leadership, teacher, and technology literature.
