This study evaluated the effectiveness of Edpuzzle, an interactive media learning tool, in enhancing student achievement in Math and English Language Arts (ELA) among grades 3-11 students in a participating California school district during the 2023-2024 academic year. Employing a retrospective design, the evaluation analyzed Edpuzzle usage data and assignment performance, and whether they predicted standardized outcomes including the CAASPP state test and Renaissance Star formative assessments. Results indicated that both teacher-created and Edpuzzle Original assignment grades were positively associated with higher performance on standardized tests, indicating the validity of the assessments, with the Edpuzzle Originals showing more consistent question difficulty levels across grade bands. Correlational analysis demonstrated that increased Edpuzzle usage predicted improved CAASPP and Star scores across grades. In addition, chi-squared tests indicated that students with high levels of Edpuzzle engagement were significantly more likely to meet or exceed grade-level proficiency compared to low-usage peers, even surpassing state averages. These findings suggest that Edpuzzle's integration of interactive video elements and embedded formative assessments can support personalized learning and inform targeted, data-driven instructional strategies. This study provides promising evidence of Edpuzzle's program efficacy and underscores the need for further research across diverse educational settings.
