Analysis of Students' Critical Thinking Skills Profile and Implementation of PBL onSound Wave Material

In the 21st century, students are expected to be able to have critical thinking skills to be able to read and solve problems in their daily lives. For this reason, it is important to determine appropriate learning models and media. Problem-Based Learning (PBL) is a learning model that can improve critical thinking skills. This research was conducted to determine students' critical thinking skills and determine the application of learning models in physics subjects, especially in the PBL learning model. The sample consisted of 50 class XI students in one of the high schools in Gresik. The research results from the question instruments show the low level of students' critical thinking skills. The results of interviews with physics educators explained that physics learning activities so far have used several innovative learning models and media. Questionnaire responses showed that students had the perception that they had met the indicators of critical thinking skills, and also showed interest in implementing the 3D digital module. So it can be concluded that there is a need to implement physics learning using the help of interactive learning media such as 3D digital modules to increase students' activeness in learning and train critical thinking skills.
