The role of education is very important to prepare students who have knowledge and skills in using technology. Physics learning in the 21st century requires teachers to make technology an efficient and innovative learning medium. One technology that is often used by students is a smartphone. Smartphones are a technology that can be used to motivate and motivate students' curiosity to learn. The purpose of this study is to see the use of smartphones in learning physics, especially sound wave material. This type of research is descriptive qualitative research. Research data were collected through questionnaires and interview sheets. Questionnaires are distributed using a rating scale. Price data is processed using a proportion technique. The results of this research are that on average students in five public senior high schools already have a smartphone. Smartphones have been used in learning. However, the use of smartphones is still limited. Smartphones have not been used as learning media in sound wave experiment activities. In addition, smartphones are more often used by students to play social media than studying. This shows that the use of smartphones by teachers and students has not been carried out optimally in learning physics, especially sound wave material.

Students need to develop their critical thinking skills, which include the 4Cs of the 21st century: creativity, collaboration, communication, and critical thinking. These 4Cs are qualities that are essential for success in the modern world. So it's important to acquire knowledge that can sharpen critical thinking abilities. In three high schools in Sungai Punuh City, the pupils' critical thinking abilities were not as good as anticipated. The first research revealed that the lack of connections between the teaching materials and the usage of physics in daily life was the root of the students' poor critical thinking skills. 77% of students said that the professors' teaching materials did not incorporate real-world applications of physics. Textbooks predominate in the instructional materials utilized, however they do not promote critical thinking or self-learning. Therefore, in order to develop students' critical thinking abilities, autonomous learning tools are required that meet their demands. In order to enhance critical thinking abilities, research was done on the construction of integrated e-modules using the CTL technique on material elasticity. The findings of expert validity tests are especially communicated in this study. Three experts from the FMIPA UNP Physics Department conducted the validity test, which had an average validity score of 85.7% in the extremely valid category. According to the validity test results, the e-module is combined with the CTL method to material elasticity to improve critical thinking abilities that are prepared to be evaluated for applicability and efficacy in the actual world.
