Timed and untimed writing and math: shared and differential cognitive predictors in primary school

Area of Science:

• Cognitive Psychology
• Educational Psychology
• Developmental Psychology

Background:

• The interplay between writing and mathematics achievement is not fully understood.
• Phonological awareness (PA), working memory (WM), and fine motor skills (FMS) are individually linked to writing and math, but rarely studied together.
• Understanding shared cognitive factors is crucial for addressing learning difficulties.

Purpose of the Study:

• To investigate the shared cognitive factors underlying both timed and untimed writing and math performance.
• To examine the differential effects of PA, WM, and FMS on various academic skills in elementary students.
• To explore the mediating roles of WM and PA in the relationship between FMS and academic outcomes.

Main Methods:

• A cross-sectional study involving 677 third- to fifth-graders with diverse academic abilities.
• Assessment of timed (fluency/automaticity) and untimed (spelling, math computation) writing and math skills.
• Statistical analysis to evaluate the relationships and mediating effects of PA, WM, and FMS.

Main Results:

• Working memory (WM) had a greater impact on timed writing than math; phonological awareness (PA) had a stronger effect on writing than math for both timed and untimed tasks.
• PA showed a stronger effect on untimed math compared to timed math.
• WM fully mediated the FMS-untimed writing link, while PA partially mediated WM's relationship with all writing and math skills.

Conclusions:

• Fine motor skills (FMS), working memory (WM), and phonological awareness (PA) are relevant to both writing and math achievement, both independently and collectively.
• The findings highlight the importance of considering these cognitive factors in educational interventions.
• This research contributes to a more robust theoretical and empirical understanding of the connections between writing and math.
