From movement to mind: Early fine motor skills are associated with cognitive performance at school age in very preterm infants.

Background: Although preterm birth is associated with deficits in both motor and cognitive functioning, the association between early motor skills and cognitive outcomes at a later age remains underexplored.

Aim: To evaluate associations between motor skills at age 5.5 and cognitive functioning at age 8.

The battle of question formats: a comparative study of retrieval practice using very short answer questions and multiple choice questions.

Background: Retrieval practice is a highly effective learning strategy that enhances long-term retention by encouraging the active recall of information. However, the optimal question format for maximizing knowledge retention remains uncertain. In this study, we compared the effect of very short answer (VSAQ) versus multiple-choice question (MCQ) practice tests on students' knowledge retention.
