Abstract

Abstrack : This research aimed to know the effectiveness of guided inquiry learning model in improving the student achievement in class XI IPA SMAN 5 Pekanbaru. This research was a quasi experiment with randomized group pretest-posttes design. The sample of this study was XI IPA 5 as experiment class and XI IPA 6 as control class after being tested for normality and homogeneity tests. Normality test was performed using Liliefors test. The results of the Liliefors normality test obtained for all the data (material prerequisites, pretest, and posttest) normal distribution where L_maks ≤ L_tabel. The results of the homogeneity test, of F_hitung<F_tabel (1.23 <1.72 with α = 0.05, dk(36.36)) which means that the samples have the same variance (homogeneous). Data analysis technique used was t-test, obtained t_hitung≥ t_table (2.398> 1.67 with dk = n₁ + n₂ - 2 and α = 0.05) means that the application of guided inquiry learning model gave effect of 8.02% to the improvement of the student achievement.
