The population in this study were all students of class XI SMA Negeri 2 Koto Kampar Hulu Academic Year 2021/2022 with a sample of 52 students consisting of class XI MIPA 1 as an experimental class tota…
One of the problems facing education today is that the ability of students to solve problems when working on questions is still very low. Students still have difficulty solving problems and steps to solve problems given in the form of questions. Students' problem-solving abilities can be trained and improved by carrying out learning activities that invite students to explore, investigate, find …
the use of a learning model consisting of an arrangement of learning activities aimed at helping students to build their understanding of concepts. One model that can be done is Conceptual Understanding Procedures (CUPs). The type of research that will be used in this study is Quasi Experimental with the Posttest Only Control Group Design research design, namely using one experimental class and…

The ability to think creatively is part of the learning concept that must be improved and trained continuously in students. Improving the ability to think creatively in students aims to make students better understand and interpret learning concepts. This study aims to determine the effectiveness of e-modules based on creative problem solving (CPS) models assisted by comics on temperature, expa…
This study aims to describe and find out the differences in cognitive learning outcomes in classes that apply learning using laboratorium virtuals, PhET Simulation and the Physics Classroom, as an experimental class compared to a class that applies conventional learning as a control class. The type of research used is quantitative with the Quasi Experimental research method and the Nonequivalen…
The nation's current generation is required to be able to master 21st century skills, one of which is critical thinking skills needed to face today's world competition with rapid technological advances. The use of this contextual STEAM-based electrical KIT aims to describe students' critical thinking abilities and to find out the differences in critical thinking abilities between the experi…
The current low student physics learning outcomes are because students tend to feel less interested and bored in learning physics because they consider physics to be a difficult subject to learn, and students assume that physics lessons have no connection with their daily lives. Therefore, learning media innovations are needed that can visualize, provide materials, and provide competency te…
Physics lessons that are abstract in nature make it difficult for students to understand them so that students' motivation to learn physics is low. Therefore, teachers must be able to create learning that can foster student motivation to take part in physics lessons, especially in dynamic fluid material, namely by using interesting and easy-to-understand teaching materials such as dynamic fluid…
