Abstract

The purpose of this study was to determine the differences in learning outcomes using Guided Inquiry learning model with Guided Discovery in Human Population Density Influence matter to the Environment. The design of research was the randomized pretest-posttest control group design. Quantitative data were such as cognitive learning results obtained from the value of pretest, posttest, and N-gain were analyzed using t test and U at the level of 5%. Qualitative data were the data obtained from the affective observation sheet and analyzed descriptively. The Results showed that the average of N-gain using Guided Inquiry was higher (61.87%) compared to Guided Discovery (26.53%). The average percentage of affective student experiment class I (83.33%) and experiment II (81.62%) had a good criteria. Thus there is a difference between Guided Inquiry learning model with Guided Discovery on student learning outcomes.Tujuan penelitian ini untuk mengetahui perbedaan hasil belajar dalam menggunakan model pembelajaranGuided InquirydenganGuided Discoverypada materi Pengaruh Kepadatan Populasi Manusia Terhadap Lingkungan.
