Subclaims¶

q3 i? Logistic regression showed no significant relationship between declarative knowledge of a feature and positive pre-to-post change in its execution, for any of the five features. → Christian Leukel 2025

Evidence¶

Christian Leukel 2025¶

Christian Leukel, Katharina Loibl. (2025). Problem-solving prior to instructional explanations when learning javelin throwing in primary school. Instructional Science. https://doi.org/10.1007/s11251-024-09700-9

q3 · i? · causal · r1

Logistic regressions tested whether declarative knowledge of each feature predicted positive pre-to-post change in its execution; none improved significantly over the null model (e.g., javelin orientation p =.09; arm positioning p =.18; impulse step p =.64; bracing step p =.15; elbow positioning p =.33).

"For the orientation of the javelin relative to the shoulder axis, logistic regression analysis with declarative knowledge as the predictor did not demonstrate a significant improvement over the null model (N = 42; model X2 = 4.07, p =.09, OR = 6.6 (95% CI: 1.0 and 131), deviance = 4.1, pseudo R 2 = 0.22)."

Discussion¶

Related Claims¶

• Adding a practice phase after instruction (PS-I + P) did not improve javelin throwing performance over PS-I alone
• Primary school children improved execution of movement features but showed no improvement in javelin throwing distance across all conditions
• Movement-feature performance predicted javelin throwing distance, with the bracing step contributing most
• In primary school children learning javelin throwing, PS-I did not outperform I-PS on throwing distance or movement-feature execution
• Working memory capacity did not moderate learning gains in PS-I and I-PS, but digit recall correlated with declarative knowledge of the features
