Longitudinal Model of Math and Vocabulary in Chilean Primary School Children

Table 1_A 7-year longitudinal model of math and receptive vocabulary in primary school is a dataset by Carolina Álvarez, last updated in May 2026. It contains results from a structural equation modeling study of 3,757 Chilean children, tracking predictors from age 3 to age 11. The analysis investigates indirect paths linking early language skills, executive functions, and home learning materials to later academic outcomes.

Use Cases

• Training predictive models for child academic development based on early cognitive and socio-economic factors mentioned in the description
• Analyzing mediation effects in educational psychology using the structural equation modeling results described
• Benchmarking interventions aimed at improving math or vocabulary skills based on the identified longitudinal paths

Strengths

• Dataset is based on a substantial sample of 3,757 children
• Longitudinal design covers a 7-year period from age 3 to age 11
• Clear methodological description using structural equation modeling

Limitations

• Row count and column-level documentation are unknown, which limits suitability assessment
• The dataset is very small (21.0 KB), suggesting it may contain only summary results or a single table
• Data reflects a specific geographic and temporal context (Chilean children), which may limit generalizability
