Abstract: This brief presents an overview of the full report, "Evaluation of the Digital Lizards of Doom Level 1 Curriculum," which studies the effectiveness of the multimedia sci-fi fantasy series Digital Lizards of Doom (DLOD) on student learning using a quasi-experimental design (QED). A total of 11 third-, fourth-, and fifth-grade teachers in the San Diego Unified School District used the DLOD curriculum resources to deliver 16 daily lessons to their students (n = 389) over a 3-4 week period. Data sources and measures included student achievement data, curriculum content, curriculum implementation observation data, and teacher interviews, focusing on teachers' perceptions of students' achievement and engagement and to explore its potential impact on reading scores. A significant interaction between grade level and treatment showed that students in higher-grade DLOD classes demonstrated significantly higher Lexile Score gains than their comparison-group counterparts. Teachers found the DLOD curriculum easy to implement, with the program strengths being its engaging story and adaptable curriculum materials.
