Abstract

The purpose of this study was to determine the effect of group investigation by sigil and learning motivation toward biology learning outcomes. This research is a quantitative research with an experimental method. The population of this study was all X grade students of IPA of SMA Negeri 61 Jakarta with a total of 140 students, the study sample was determined by a cluster sampling technique of 2 classes with a total sample of 70 students. The learning strategy in the experimental class used the group investigation by sigil with group discussion method while the control class used the lecture method. The research hypothesis test used two-way analysis of variance with a 2x2 factorial design and a significant level of 5%. The analysis prerequisite test that is carried out is the normality test using Kolmogorov Smirnov and homogeneity test using Barlett test. From the results of the analysis it can be concluded that (1) there was an influence of group investigation by sigil toward biology learning outcomes, (2) there was effect between the level of learning motivation in biology learning outcomes; 3) there was no interaction between group investigation by sigil and learning motivation toward biology learning outcomes.
