Insights
Mastery motivational climate (MMC) interventions improve fundamental motor skills (FMS) in preschoolers. Intervention length may be less critical than focusing on specific skill mastery patterns for optimal FMS development.
Area of Science:
- Child Development
- Motor Learning
- Educational Psychology
Background:
- Mastery motivational climate (MMC) interventions effectively enhance fundamental motor skill (FMS) competence in preschool children.
- The optimal duration or "dose" of MMC interventions for maximizing FMS gains remains unestablished.
- Understanding skill mastery progression is crucial for optimizing intervention strategies.
Purpose of the Study:
- To compare FMS competence in preschool children across two different doses of MMC interventions.
- To describe the changes and patterns of FMS "mastery" within these intervention doses.
- To investigate the relationship between intervention duration and FMS development.
Main Methods:
- Secondary data analysis from a larger MMC intervention study involving 32 preschool children (mean age 4.4 years).
- Fundamental motor skill competence assessed using the Test of Gross Motor Development, 3rd Edition (TGMD-3) at mid-intervention and post-intervention.
- Statistical analysis included a two-way mixed ANOVA to examine group and time effects on locomotor and ball skills.
Main Results:
- Both intervention groups showed significant improvements in locomotor skills over time, with the MMC group improving faster.
- For ball skills, the MMC group improved significantly by mid-intervention, while the comparison group improved only from pre- to post-intervention.
- Running and sliding were the most mastered locomotor skills; overhand and underhand throwing were the most mastered ball skills. Skipping, galloping, hopping, and striking skills were least mastered.
Conclusions:
- Intervention duration (instructional minutes) may not be the most effective measure for a dose-response relationship in MMC interventions.
- Focusing on the specific patterns of skill mastery is essential for informing practitioners on allocating instructional time effectively.
- Tailoring intervention delivery based on skill acquisition trajectories can optimize FMS competence in young children.
Abstract:
Previous mastery motivational climate (MMC) movement interventions have enhanced fundamental motor skill (FMS) competence across diverse groups of preschool-age children. Yet, an adequate intervention length has not been established. Our purposes in this study were to (i) compare FMS competence in preschool children across two doses of MMC interventions, and (ii) describe changes in children's FMS 'mastery' across doses. We used secondary data analysis from a larger MMC intervention study in which 32 children (M = 4.4) received FMS testing (TGMD-3) at the mid-point of intervention and at post-intervention. A two-way mixed ANOVA with Group as the independent variable and FMS competence across three Time points as the repeated measure was significant for both Group and Time main effects for locomotor and ball skill competences separately. There was a statistically significant interaction between Group and Time on locomotor (p = .02) and ball skills (p < .001). Both groups showed significant improvements in their locomotor skills at each time point, but the intervention group improved faster than the comparison group. For ball skills, only the MMC group significantly improved by mid-intervention, and the comparison group showed significant improvements from pre-to post-intervention only. Children in this study were most likely to show mastery in running first, followed by sliding at mid-intervention. Few children mastered skipping, galloping, and hopping across the study. For ball skills, overhand and underhand throwing were more likely to be mastered, and few children mastered one and two-hand striking across the study. Collectively, these findings suggest that duration of instructional minutes may not be the most effective proxy for identifying a dose-response relationship of MMC intervention. Moreover, focusing on the patterns of skill mastery can help inform researchers and practitioners as to how to allocate instructional time during MMC interventions to optimize FMS competence for young children.
