Access to Information is increasingly at the forefront of AI-driven technologies. Zelma, an innovative tool from Brown University, highlights this objective, as it aims to to make US state assessment data more assessable using its AI-powered interactive platform.
What is Zelma?
Zelma is a comprehensive database containing all publicly available assessment data from all 50 states and D.C. for students in Grades 3-8. It integrates this data across state, district, and school levels, disaggregated by subject, grade level, and student subgroups. This integration provides valuable insights into proficiency trends and changes in achievement gaps over time.
Developed by a team led by economics professor Dr Emily Oster at Brown University, Zelma is unique in its approach. It not only collates data from State Education Agencies but also integrates important identifiers from the National Center for Education Statistics (NCES) to aid researchers.
Who Can Use Zelma?
Zelma is for everyone. Specifically, it targets educators, education leaders, journalists, policymakers, parents, researchers, and students. Its user-friendly design and AI-powered interface allow individuals to ask questions and explore data regarding states, districts, or schools in a visually engaging way.
Key Features and Use Cases?
Data Accessibility
Zelma hosts a vast array of data, including proficiency data sourced directly from State Education Agencies, district and school characteristics from NCES, and additional "flags" for researchers tracking changes in assessments over time.
Zelma provides extensive data access, including proficiency data sourced directly from State Education Agencies, alongside district and school characteristics from the NCES. Additionally, it features specific markers for researchers, which are designed to help in tracking any modifications that occur in assessment methodologies, standards, or content across different years.
Coverage
The platform includes data from annual statewide summative assessments in English Language Arts (ELA), Math, and other subjects like Science, Social Studies, and STEM, depending on state availability.
Comparability
It's important to note that Zelma's results are not comparable across states due to the distinct assessments and proficiency definitions used by each state.
User Engagement
Zelma enables users to ask natural language questions, making data exploration intuitive and straightforward. For example, one can query, "Show me math scores in Alaska over time" or "Compare reading scores in Brookline, MA, with the rest of the state."
Data Download and Sharing
Users can download state data as csv files and share their queries easily through a dedicated share button.
Educational and Research Implications
Zelma is a treasure trove for educators and researchers. By providing up-to-date, comprehensive data, it enables them to identify trends, assess achievement gaps, and make informed decisions. Journalists and policymakers can use Zelma to report on education trends and craft policies based on solid data.
Zelma's Limitations and Terms of Use
While Zelma is a powerful tool, it does have limitations. It does not include student-level data or personal identifiable information, focusing instead on broader state, district, and school-level data. Additionally, data suppression is applied to protect personal information, meaning some subgroup data might be omitted if it includes too few students.
