Gaining Data Literacy through Professional Development

Data Literacy and Action Research

Data literacy, as described by Mandinach and Gummer (2016), encompasses the ability to understand, interpret, and use data effectively in educational settings. This proficiency is important for educators aiming to foster meaningful classroom changes that are informed by solid evidence rather than intuition or tradition alone. In the context of P–12 education, data literacy enables teachers and administrators to make informed decisions that directly impact student learning and achievement (Henderson & Corry, 2021). This concept supports the development of a school climate that values and utilizes data in all aspects of its operation, from daily classroom activities to strategic planning for future educational endeavors.

In my educational setting, data is collected through various means, including standardized tests, classroom assessments, surveys, and observational records. The means are all different and useful in different ways. The data from standardized tests, for example, are helpful for identifying trends, progress, gaps, and areas of strength or need at both individual and collective levels. Classroom assessments, on the other hand, provide immediate, actionable data that teachers can use to adjust their instructional strategies to meet the needs of their students; it is helpful for understanding daily student performance and progress toward learning objectives (Cai et al., 2020). This data is then shared among educators and stakeholders in a structured manner, often during professional development sessions, staff meetings, or through digital platforms designed for educational data analysis. Decision-making processes are increasingly data-driven, with teams of educators collaboratively analyzing results to identify areas of need, set goals, and plan interventions. However, while data is being collected and used, the depth of data literacy among staff varies, which indicates a potential area for growth.
