Abstract
Abstract 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.

Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from it
