q2 i3 The experimental group (N=124) increased LPCI overall scores from 21.2% to 33.7%, F(1, 123) = 72.7, p < 0.001, partial eta-squared = 0.371. → Jennifer Wilhelm 2009 q2 i3 The control group (N=66) increased LPCI overall scores from 26.6% to 38.5%, F(1, 65) = 48.1, p < 0.001, partial eta-squared = 0.422. → Jennifer Wilhelm 2009 (2)

q2 · i3 · causal · r1

Repeated measures ANOVA on the experimental group's LPCI pre-post scores (N=124) in this quasi-experimental study. The article reports a "significant increase in the mean valXes" with partial eta-squared 0.371; gain scores were 12.1% for males and 13.0% for females.

"A 5MA129A revealed a significant increase in the mean valXes from pre (21.2%) to post (33.7%) on overall test scores, F(1, 123) 72.7, p 0.001, partial 2 0.371."

q2 · i3 · causal · r1

Repeated measures ANOVA on the control group's LPCI pre-post scores (N=66), taught by a teacher with 29 years experience using her regular Earth/Space lessons. The article reports a "significant increase in the mean valXes" with partial eta-squared 0.422.

"A 5MA129A revealed a significant increase in the mean valXes from pre (26.6%) to post (38.5%) on overall test scores, F(1, 65) 48.1, p 0.001, partial 2 0.422."

• Experimental students gained on lunar periodicity LPCI domains while only the control group gained on the phase/Sun-Earth-Moon positions domain — related
• Post-test scores on the LPCI, GSA, and PSVT-Rot were significantly correlated for every group except control males on PSVT-Rot versus LPCI — related
• Only female students made significant gains on the Geometric Spatial Assessment, and no male group gained on any GSA domain — related
