Effect of concept attainment model on student’s science process skills

Abstract

The research objective was to determine the effect of the concept approach model on students’ science process skills. The type of research used is experimental research with pre-experimental methods and one group pre-test post-test design. The research sample was selected for grade I at Peukan Bada Senior High School. Data collection used non-test instruments in the form of observation sheets to see students’ science process skills. The results of data analysis using the percentage formula showed an increase in science process skills from the first meeting to the third meeting. At the first meeting, the average percentage was 54.66%, which was categorized as sufficient, at the second meeting it was 76.66% which was categorized as good, while at the third meeting it was 84.47% which was categorized as very good. The indicators of science process skills with the highest improvement were observation, interpretation, prediction, and concept application. Meanwhile, the lowest indicators are classification, experimental design, and communication.
