Abstract
This study examined the changes in the communication skills of preschool students with autism spectrum disorder (ASD) that resulted from an intervention that featured three evidencebased, transactional approaches to augmentative and alternative communication (AAC) intervention: (a) attributing communicative meaning to student behaviours; (b) providing aided language input; and (c) focusing on graphic symbols representing core vocabulary. Using a mixed-methods design with multiple sources of data (i.e., observation field notes, IEPs, and direct communication assessment), the study was conducted in three classrooms with 6 educators and 13 preschool students with ASD. The purpose was to explore interaction patterns between educators and students while also analyzing improvements in student communication as measured by the Communication Matrix. The results point to a transactional relationship between educators’ and students’ communication across the three classrooms. This group of preschool students with ASD learned to use abstract graphic symbols representing core vocabulary to request as a result of educators’ focus on this requesting. A number of students demonstrated growth in use of non-symbolic communication for social interaction and information sharing as a result of educators’ increased use of aided language input.

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
