ABRACADABRA (ABRA) is an evidence-based suite of interactive multimedia that engages learners in the development of core reading skills. This meta-analysis presents an update of the research evidence about the effectiveness of ABRA for elementary students. It reports 91 effect sizes in six reading-related outcomes for a sample of 7,388 students. Regardless of context and measurement type, the studies yielded positive effects of ABRA, ranging in magnitude from g+ = 0.080 for "Vocabulary Knowledge" to g+ = 0.378 for "Phonemic Awareness" and reaching statistical significance in four outcome categories. This meta-analysis adds to our understanding of the effectiveness of ABRA-based reading instruction by exploring factors of research design, ABRA design and implementation contexts, and various student characteristics and offers implications for instructional practice.
