Analysis of Increasing Students' Learning Interest Through the Implementation of the Project-Based Learning Model

The purpose of this study is (1) to find out whether there is an increase in students' interest in learning chemistry through the application of project-based learning methods, (2) to find out how much increase in students' interest in learning chemistry through the application of project-based learning methods to the material nature of chemistry. This research design uses Pre-Experiment: Group Pretest-Posttest. The population of this study was all students of class x, with a total of 35 samples. The research instrument in the form of observation sheets and questionnaire instruments amounted to 25 statements using a Likert scale, and the number of answer choices was a choice from never to always. The test requires analysis using the data before showing that the data is normally and evenly distributed. Hypothesis testing was carried out using a parametric test, namely the One Samples T-test, at a significance level of 0.05 with the help of the SPSS for Windows Version 22 program. The results of this study obtained t_count (122,978) > t_table (1,69092) and sig. 0.000 < 0.05. Based on data analysis and hypothesis testing, it is known that students' interest in learning chemistry increases through the application of project-based learning methods. Increasing students' interest in learning chemistry through applying project-based learning methods using gain testing with a score of 0.5 in the medium category.
