The Effect of Using Simple Aircraft Concrete Media on the Mastery of Concepts in Inquiry Science Learning in Elementary School Students

This study aims to determine the increase in mastery of concepts in inquiry learning science through simple concrete media. This research is expected to help teachers solve the problems of learning science at the elementary school level. The research approach used quantitative research with a quasi-experimental method and a nonequivalent control group design. The study involved 60 fifth grade students of SDN 1 Nagrikidul, Purwakarta district. In the control class, conventional learning assisted by audio-visual media is applied. And the experimental class applied science learning by inquiry using concrete media. The results showed that the gain normalization test for increasing the mastery of science concepts in the experimental class (N-gain 0.44) was greater than the control class's gain value (N-gain 0.23). Based on the test results, the difference between the two means is obtained count = 3.368 ttable = 2.045, with a sig. 0.002 α amounting to 0.05, then H0 is rejected, and Ha is accepted. Therefore Inquiry science learning by utilizing concrete media can significantly improve the mastery of science concepts in elementary school students.

Pengembangan Bahan Ajar IPA Berbasis Inkuiri Terbimbing untuk Meningkatkan Literasi Sains

The purpose of this study is to produce a product in the form of science teaching materials that can improve the scientific literacy of students. This research is included in research and development of education which is a method for producing certain products and testing the effectiveness of these products. The product developed was validated by experts consisting of 3 people. Learning tools that are validated are syllabus, lesson plans, and scientific literacy instruments. The results of the study show that the learning device in the form of syllabus shows an average of 3.9 (78%) in the appropriate category, the Learning Implementation Plan (RPP) shows an average of 3.9 (78%) in the feasible category, and the items show the average value is 4.1 (82%) in the feasible category. Thus, inquiry-based science teaching materials developed in appropriate categories can be applied in learning. The results of the questionnaire response analysis of students showed that students' responses were very good for teaching materials because 77.8% of students were fluent that guided inquiry-based teaching material was interesting. In a large-scale trial, the N-gain value obtained in the experimental class was 70.74 with high criteria. Keywords: Science Teaching Materials; Guided Inquiry; Science Literacy
