Black and Wiliam Study

The Black and Wiliam Study, conducted in 1998, examined how formative assessment—ongoing, informative feedback during learning—improves student achievement. They found that when teachers routinely assess students’ understanding and adjust instruction accordingly, learning outcomes significantly improve. This approach encourages active student engagement, self-assessment, and tailored teaching strategies. The study highlights that effective formative assessment is a powerful tool for enhancing educational results, emphasizing the importance of feedback and adaptation in the learning process.
