  • Measuring Hate Speech: Unifying Deep Learning with Item Response Theory

    Claudia Natalia von Vacano & Chris Kennedy, D-Lab UC-Berkeley

    Overview The hate speech measurement project began in 2017 at UC Berkeley’s D-Lab. Our goal is to apply data science to track changes in hate speech over time and across social media. After two and a half years we are now nearing the completion of a comprehensive, groundbreaking method to measure hate speech with precision while mitigating the influence of human bias.

  • Novice Study of Teacher Learning Progressions in Posing, Pausing and Probing Practices: A Multi-Dimensional IRT Analysis

    Brent Duckor, Carrie Holmberg with Yidan Zhang

    Abstract Research on teachers and teaching has shown that formative assessment can improve student learning more than most instructional practices (Hattie 2009, 2012). A robust body of empirical evidence spanning over two decades indicates that thoughtfully implemented formative assessment practices improve students’ learning, yet little empirical work has been done on teachers’ developmental trajectories with these so-called high-leverage moves.
