Abstract

The purpose of this research was to know the influence of PBI model to self efficacy and students learning outcomes on the influence of population density to environment subject matter. The design of this research was control group pretest-posttest. The samples of this research were the students at VIIA and VIIB SMPN 2 Seputih Mataram which were chosen by purposive sampling. The learning outcomes were analyzed statistically by using one way anova. The qualitative data were the increasing of self efficacy which were obtained from questionaire and analyzed descriptively. The result showed that the average of self efficacy in experiment class (76) was higher than control class (67,8) and students learning outcomes increased significantly with the average in experiment class (62,2) and control class (54). Based on this research, it can be concluded that the PBI model gave influence to self efficacy and students learning outcomes.Penelitian ini bertujuan untuk mengetahui pengaruh model PBI terhadap Self efficacy dan hasil belajar siswa pada materi pokok pengaruh kepadatan populasi manusia terhadap lingkungan.

Abstract

The purpose of this research was to know the influence of problem based instructions model on self efficacy and students learning outcomes in environmental management . The design of this reserach was quasi experimental with non equivalent pretest-postest. Population were 7th grade student at SMP N 1 Seputih Mataram. Analysis of the quantitative data in this research was using ANOVA test. These result in ANOVA test showed a significance level of 5%. Qualitative data were self efficacy which was analyzed descriptively. Self efficacy average on experimental class get sufficient characteristic (82,94%). This increasing was followed by student learning outcome. The result showed that learning outcomes of experiment class was sufficient characteristic (63) and control class get low characteristic (42). Based on this research, it can be concluded that the problem based instruction model give influence to self efficacy and students learning outcomes in human role in environmental management to improve pollution and damage of environment subject matter.Penelitian ini bertujuan untuk mengetahui pengaruh model pembelajaran Problem Based Instruction terhadap self efficacy dan hasil belajar siswa pada materi pengelolaan lingkungan.
