Application of PjBL Model by Utilizing Natural Materials Chemistry to Improve Students' 4C Skills

Abstract

The purpose of this study was to examine the effectiveness of implementing a project-based learning model by utilizing natural materials to improve students' 4C skills. 4C skills include critical thinking, communication, collaboration, and creativity skills. The sample used in this study were students who attended the R-001 class of natural material chemistry lectures in the 2023/2024 academic year of the Jambi University Chemistry Education Study Program. This research is a quasi-experimental type research with a one group pretest-posttest scheme design. Data on 4C skills were obtained using a questionnaire before and after the application of the project-based learning model by utilizing natural chemistry. Data on 4C skills were then subjected to paired samples t test. The results of the paired samples t test significance test showed a value of 0.00. These results are smaller than 0.05, so this study shows that the application of the project-based learning model by utilizing natural materials can improve students' 4C skills.

Increasing Student Creativity and Collaboration in Biochemistry Practicum through the Application of Project Based Learning Model

“…This demonstrates that using a project-based learning approach in the biochemistry practicum helps students become more creative and collaborative. The research Harizon & Ekaputra, (2023) indicating that the project-based learning model has an influence on developing communication skills, critical thinking, teamwork, and student creativity is compatible with the effectiveness of the model in enhancing student skills. Project-based learning makes student creativity increase in solving and solving problems encountered in the process of completing the project (Sari & Angreni, 2018).…”
