Subclaims¶

q2 i? The developmental dynamic of connectedness (RE dropping, LCC/LSC rising) was interrupted between the third and fourth assessments, coinciding with school vacations, and the post-vacation pattern mirrored the beginning-of-year pattern; the authors interpret this as a school-environment effect. → Bárbara Malcorra 2024

q2 · i? · associational · r1

Interpretation of the longitudinal graph-attribute trajectories shown in Fig. 1c across the five assessments; the article describes the vacation-period interruption and the resumed pattern after returning to school as evidence of a school-environment effect.

"As short-range recurrences (RE) decrease, connected-ness (Largest Connected Component (LCC) and LSC) increases, with an interesting interruption of this dynamic between the third and the fourth measures (related to vacations in the middle of this school year). This result points to an effect related to the school environment."

Discussion¶

Learner Variables¶

• Oral Language — outcome: instruction changes it
• Time and Continuity — predictor: learners who differ on it differ in outcomes
