Abstract
Abstract: Learning models play an essential role in the implementation of the learning process to achieve optimal learning outcomes. The choice of learning model needs to be adjusted to the characteristics of the students and the material. This research aims to determine the effectiveness of the Investigation Through Cooperative Problem Solving (ITCPS) learning model on science learning outcomes. This research uses a quasi-experimental approach with a pretest-posttest control group design and cluster random sampling techniques. The population of this study was class VII of Junior High Schools in Karanganyar, Surakarta, Central Java, Indonesia. Collecting data on Class VII living creature classification material uses technical tests for the knowledge aspect, questionnaires for the attitude aspect, and observation sheets for the skills aspect. Analysis used the Wilcoxon test, independent sample t-test, and n-gain score. The research results show that the ITCPS learning model is adequate for learning outcomes in science knowledge aspects with a positive rank value that is greater than the control class and an n-gain test score of 30.15 (moderate increase). The learning outcomes for the attitude and skills aspects show the value of Asymp. Sig. (2-tailed) is less than 0.05, thus interpreting the difference in influence in the two classes. This research implies that the ITCPS learning model is effective in science learning outcomes.
