Learning devices are tools or equipment that are used by teachers in carrying learning activities. The learning tools are needed so that learning does not feel monotonous and boring, and can increase the activity of students. The learning tool developed is a learning device based on the Learning Cycle 7E model on work and energy materials for class X senior high school, which consists of a Lear…
Science learning is often considered a difficult subject that is identical to complex formulas that make students less interested in the learning being taught. Students find it difficult to understand the material because the implementation of learning in the classroom is still monotonous and the supporting media are less attractive, this makes students feel bored and bored until finally ma…

The design used is quasiexperimental: posttest only control group design.The study participants were 66 students in 11th graders. Data were collected through the test. The data collection instrument was in the form of sound waves science process skills test w…
Understanding is one of the cognitive abilities that students must have to master physics concepts. A low understanding of the concept of physics is a problem that must be solved. The selection of the right learning approach and the use of interactive media when learning is expected to increase the understanding of students' concepts. This study aims to determine the effectiveness of learning b…
Physics is a science that has an important role in the world of education, because physics is a tool that can be used to shape students to think critically, logically, analytically and systematically. Activeness in learning physics lies in two aspects, namely active in action (hands activity) and active thinking (minds activity). In addition, students will be active if students can relate new k…
Understanding is the level of ability expected by someone in understanding the meaning of the concept. Understanding the concept is a very important part in the learning process. The purpose of this study is to find out that the application of the predict-observe explain (poe) learning model can be an alternative solution to improve students' understanding of physics concepts. This study uses a…
Pembelajaran fisika merupakan suatu proses penemuan yang didalamnya terdapat keterampilan-keterampilan dasar yang biasa digunakan para ilmuwan dalam bekerja secara ilmiah untuk memperoleh produk atau pengetahuan yang diharapkan. Salah satu materi yang penting dalam pembelajaran fisika adalah materi hukum Newton. Namun ditemukan ketidaksesuaian antara kompetensi dasar materi hukum newton yang me…
Students science process skills are aspects that must be trained through hands-on practicals. In fact, the lack of adequate practicum facilities in the physics laboratory causes students to rarely do practicums so that students' scientific process skills do not develop. Along with the rapid development of technology, there has been an innovation in the form of a virtual laboratory as an alterna…
The type of research used is Research and Development (R & D) using the 4D model (Define, Design, Development and Dissemination) which aims to develop a summative test instrument in physics learning in the odd semester of X grade SMA assisted by Wondershare Quiz Creator software as a medium for making computer-based test. The test instrument consists of 40 multiple choice questions with 5 answe…
This study aims to determine students' science process skills after using the guided discovery model assisted by the virtual PhET lab on vibration and wave materials and the effectiveness of the application of the guided discovery learning model assisted by the virtual PhET lab. This research was conducted at SMPN 2 Siak. The research method used is a quasi-experimental design with a posttest o…
The ability to analyze physics is one of the skills needed in today's 21st century. This study aims to determine the ability to analyze students and to determine the difference in the ability to analyze high school students using the KIT Mechanics media and not using the media in the Business and Energy material for class X SMA Negeri 1 Kandis. This type of research is a quasi-experimental desi…
Physics is a subject that is less attractive to high school students in general, this is due to the lack of applications of physics in everyday life, especially in the matter of equilibrium and rotational dynamics. Therefore, the purpose of this study was to develop a video lesson on the subject of equilibrium and class rotation dynamics using a valid Adobe Flash application. The type of resear…
Concept understanding is defined as the ability of an individual to understand a certain concept. Students can not be said to have an understanding of the concept if students have not been able to explain the material that has been studied. At this time the learning process is still not optimal in developing the abilities of students. The application of the POE learning model assisted by PhET s…
The development of Science and Technology has led the word to the industrial revolution 4.0 which requires a teacher to be able to keep up with the times. In addition, the lack of use of innovative and interesting leanring tools for students, so it is necessary to develop practical and interesting teaching materials based on scientific investigation. Thare are also learning tools used in the fo…
This research aims to develop an experimental guide animation video using the Powtoon application on Momentum and Impulse material for class X SMA and to produce a valid experimental guide animation video media and worthy to be used as learning media in the classroom. The type of this research is Research and Development with ADDIE development model (Analysis, Design, Development, Implemen…
The purpose of this study is to describe the effectiveness of the application of learning media based on a scientific approach using augmented reality to improve students' critical thinking skills.
