Effects of a kindergarten phonological awareness intervention on grade one reading achievement among Spanish-speaking children from low-income families
Bibliographic record
Abstract
Abstract There is little knowledge about the effects of kindergarten Spanish phonological awareness interventions on literacy outcomes of grade one children from vulnerable environments. To fill this gap, this study evaluates the effects of a kindergarten phonological awareness intervention on grade one literacy skills in Spanish speaking children (N = 178) from low-income neighborhoods in Argentina. The three-month program delivered at the beginning of kindergarten included 34 lessons focused on phoneme segmentation, categorization, and blending, and letter-sound knowledge. Using a pretest-posttest comparison-group design, measures of phonological awareness, word reading, and spelling were collected before the intervention, immediately after the intervention, and one year later when children were finishing grade one. In addition, reading comprehension was examined at the end of grade one. Results reveal that the intervention had significant effects on phonological awareness, letter-sound knowledge, word reading, spelling, and reading comprehension. These findings suggest that a systematic, phonological awareness intervention program delivered during kindergarten to native speakers of Spanish has a positive impact on their grade one literacy outcomes.

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 itClassification
machine, unvalidatedMachine predicted; a candidate call from one teacher head, not a consensus.
