This paper presents our systematic review of empirical learning analytic studies carried out at K-12 education with a specific focus on pedagogically innovative (constructive) approaches on technology-mediated learning, such as knowledge building, knowledge creation, and maker-centered learning and maker culture. After reading abstracts of identified 236 articles, we zoomed in on 22 articles. We identified three categories of studies: 1) articles oriented toward methodology development, 2) articles relying on digital tools (learning environments with LA functions) and 3) articles investigating the impact of LA.
