The Influence of Concept Attainment Models on Science Processes Skills

Abstract

Science process skills are very important in the learning process. Because science process skills impact learning effectiveness. The purpose of this study was to determine the effect of the Concept Attainment Model on the science process skills of students of class XI Science on fluid material in Adiluwih 1 State High School. The instrument used to collect data is using an observation sheet with LKPD assistance. This type of research is quasi-experimental with the Pretest-Posttest Control Group design and uses saturated sampling techniques. Hypothesis testing was carried out using t-test statistical techniques to test the difference in mean scores of students' scientific process skills with significance (= 0.05), the testing criteria that is if tcount < ttable then H0 is accepted, and if tcount ≥ ttable H0 is rejected. Based on the results of the hypothesis testing it appears that tcount> ttable, namely 4.183> 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.
