The Effectiveness of Using Learning Media 3D Pop-Up Chemistry Assisted by Project Based Learning (PjBL) Learning Model Against Student Learning Outcomes on the Subject of Colloid Systems in SMA Negeri 12 Samarinda

Abstract

Background: Learning media is one important aspect that can affect the quality of student learning at school. Lack of use of media in the learning process can affect student motivation and learning outcomes in schools, the growth of globalization and technological advances requires teachers and students to be more creative in using technology in the learning process. 3D Pop-Up Chemistry media is a medium that provides visualization of stories or concepts in an interesting way with an image or theory display that can stand when the page is opened with the effect of several movable parts, this media is equipped with a barcode system that will automatically be connected to the learning video and test online on chemical materials, namely the colloid system, to support the learning process and student activity, the project based learning (PjBL) learning model is used, the PjBL learning model is an innovative student-centered learning model and assigns teachers as motivators and facilitators, in which involves a project in the learning process. This study aims to determine the effectiveness of the use of 3D Pop-Up Chemistry learning media with the Project Based Learning (PjBL) learning model on the subject of the colloid system in SMA Negeri 12 Samarinda. Materials and Methods: This research is a type of quantitative research using pre-experimental design type one group pretest-posttest with 36 students as research subjects, the sampling technique is purposive sampling, data collection techniques are carried out through tests and observation sheets which are analyzed with the N-Gain test obtained from the students' pre-test and post-test scores. Results: The results showed that student learning outcomes before and after using media 3d pop-up chemistry with a project based learning model were 40.69 for the pre-test score and 82.85 for the post-test score with an N-gain value of 0.71 ( Very effective). Conclusion: Based on the research conducted, it was concluded that the learning media 3d pop-up chemistry with the project based learning (PjBL) learning model was very effective in the learning process of colloid material chemistry
