The Influence of Concept Attainment Models on Students’ Conceptual Understanding

The purpose of this study was to determine the effect of applying the Concept Attainment model on students' conceptual understanding. The type of research used is quasi-experimental design with Pretest-Posttest Control Group using saturated sampling technique and obtained by class XI IPA2 as an experimental class and class XI IPA1 as a control class. The instrument used to collect data in this study is using multiple-choice tests with a reasonable number of 14 questions. Hypothesis testing is done by t-test statistic technique to test the mean difference of students' concept comprehension scores with significance (α = 0.05) with testing criteria if t-count t table H0 is rejected. Based on the results of the conceptual understanding hypothesis test of the control class and experimental class, it appears that t count> t table, namely 14.71> 2.015 so that the null hypothesis (H0) is rejected and the alternative hypothesis (H1) is accepted. With the acceptance of H1 in testing the hypothesis, it can be concluded that this study can test the validity of the hypothesis that there is a significant effect of using the Concept Attainment model on the understanding of the concept of class XI students on the fluid material.
