Team Teaching Models in Primary Physical Education: Effects on Basic Motor Competencies and Self-Reported Physical Literacy

Background/Objectives: To address the inconsistent provision of specialist physical education (PE) in primary schools, this study investigated the comparative efficacy of distinct team-teaching configurations. The objective was to compare these instructional models' impact on students' basic motor competencies (MC) and self-reported physical literacy (PL). Methods: This quasi-experimental, cluster-randomized study involved N=266 students (grades 1-4) assigned to one of five instructional models: single PE teacher or four team-teaching configurations (Generalist Teacher + PE Teacher [GT+PE T], Generalist Teacher + Assistant Teacher [GT+AT], Generalist Teacher + Sports Coach [GT+C], and PE Teacher + Assistant Teacher [PE T+AT]). The five-month intervention included two 45-minute PE lessons weekly. Motor competence (MC, MOBAK) and perceived physical literacy (PL, PLAYSelf) were assessed pre- and post-intervention. Given the cluster design and non-normal data, non-parametric tests were used; Kruskal-Wallis H-test compared change scores between groups, complemented by Spearman’s rank-order correlations for construct alignment and covariate analysis. Results: Statistically significant within-group overall MC gains were achieved exclusively by configurations including a qualified PE teacher (GT+PE T and PE T+AT; p < 0.05). The GT+PE T model showed the largest positive change, including significant PL improvement (Δ = +5.65). Conversely, the GT+C model resulted in a significant decline in self-reported PL (Δ = -9.16). A small but significant positive correlation (ρ = 0.149) emerged between Object-Movement skills and Perceived Physical Literacy post-intervention. Conclusions: The effectiveness of collaborative PE instruction is highly dependent on the explicit inclusion of a qualified PE teacher, reinforcing the crucial role of specialized pedagogical content knowledge. Models lacking this core expertise may be detrimental to both motor skill development and the affective components of physical literacy. These findings highlight the need for policy focused on high-quality, PE teacher-led primary PE.
