Effect of Marble Play on Handgrip Strength and Handwriting Among School Going Children.

In 2022, Audrey Saile and Mohd Hanafi Mohd Yasin hey conducted a study in Malaysia, to investigate the efficacy of fine motor training for improving handwriting legibility among students with special educational needs. Their study used a quasi-experimental pre-test/post test design but was limited by a very small, purposefully selected sample of only four students.

Despite this limitation, the results indicated a positive outcome: the treatment group showed an average 15-point increase on a modified Handwriting Legibility Scale, improving their performance from "very poor" to "moderate." The authors concluded that fine motor training is a valuable intervention for enhancing the handwriting skills of SEN students.

Current literature reveals a significant gap in research examining marble play as a targeted fine motor intervention. While existing studies have explored the effectiveness of various manipulative activities such as clay modeling, bead threading, and drawing exercises for fine motor development, there is a notable absence of research that specifically isolates and examines the unique benefits of marble play. This represents a critical oversight, given the accessibility and affordability of marbles as intervention tool. The findings of this study will provide much-needed, evidence-based guidance for educators and therapists, particularly those working in resource-limited environments.

Inclusion criteria

• Children enrolled in Grade 1-3 (typically aged 6-9 years)
• Children with normal cognitive development, as assessed by school records or teacher reports
• Students with average or below average handwriting fluency (based on teacher observation or pre-test).
• Parental or guardian consent obtained for participation.
• Regular school attendance and ability to participate in intervention sessions.

Exclusion criteria

• Children with significant visual or motor impairments that may affect fine motor coordination.
• Participants with a known history of dust allergy or diagnosed allergic rhinitis triggered by dust exposure will be excluded.
• Individuals with a current or recent (within the last 6 months) fracture of any upper, wrist, or hand) will be excluded.
• Students with a history of behavioral issues that would prevent consistent participation in structured play.
