ST-PCNN: Spatio-Temporal Physics-Coupled Neural Networks for Dynamics Forecasting

Ocean current, fluid mechanics, and many other physical systems with spatio-temporal dynamics are essential components of the universe. One key characteristic of such systems is that they can be represented by certain physics laws, such as ordinary/partial differential equations (ODEs/PDEs), irrespective of time or location. Physics-informed machine learning has recently emerged to learn physics from data for accurate prediction, but they often lack a mechanism to leverage localized spatial and temporal correlation or rely on hard-coded physics parameters. In this paper, we advocate a physics-coupled neural network model to learn parameters governing the physics of the system, and further couple the learned physics to assist the learning of recurring dynamics. Here a spatio-temporal physics-coupled neural network (ST-PCNN) model is proposed to achieve three goals: (1) learning the underlying physics parameters, (2) transition of local information between spatio-temporal regions, and (3) forecasting future values for the dynamical system. The physics-coupled learning ensures that the proposed model can be tremendously improved by using learned physics parameters, and can achieve useful long-range forecasting (e.g., more than two weeks). Experiments using simulated wave propagation and field-collected ocean current data validate that ST-PCNN outperforms typical deep learning models and existing physics-informed models.

Gains in active learning of physics: a measurement applying the test of understanding graphs of kinematics

To teach the subject of physics in the classroom it is required that the teacher has and plans to carry a didactic strategy with him. Within this context is the methodology called Active physics learning, which is a strategy within the classroom and in the laboratory, as it allows the student to learn physics without depending on a textbook or the teacher who guides the course. The test of understanding graphs of kinematics assesses students’ comprehension of kinematics. We report the application of an active learning experience for the conceptual learning of kinematics of students taking the subject of physics in an elementary and middle school. The study is quasi-experimental with a single group of 29 students using a pretest-intervention-posttest design. With the results of the pretest and posttest the Hake learning gain index was estimated and showed evidence of the implementation of active learning in the conceptual evolution of students in kinematic concepts and their representation by means of graphs. This becomes a precedent for the improvement of pedagogical practice in favor of quality education.

Application of Snowball Throwing Model to Improve Students’ Understanding of Concepts and Communication Skills in Gas Kinetic Theory

This research is based on the number of students who find it difficult to learn physics because of the lack of understanding of concepts and only memorization and still lack of communication skills of students. Based on this background, a study was conducted that aims to improve the understanding of students' concepts and communication skills by applying snowball throwing learning model on gas kinetic theory material. The method used in this study is experimental method, the population in this study is all students of XI IPA SMA IT Nurul Jannah and then selected with simple random sampling technique so that there are 23 students of grade XI IPA SMA IT Nurul Jannah. The result of the study is the application of snowball throwing model can improve the understanding of the concept with a pretest average of 25,6 and then increase by a posttest average of 57,4, with a large N-gain of 0,4 so that the medium category and t-test results of 7,65 are greater than the table t with a confidence level of 5%. The snowball throwing learning model can also improve students' communication skills, with an initial average of 45,41 and after the application of the model to 67,15, with a large N-gain of 0,4 so that the medium category, as well as the t-test results are 8,48 greater than the large, t-table that is 2,07. So, it can be concluded that the Learning Model of Snowball Throwing can improve the concept and communication skills understanding of student. For further research, it is recommended to utilize learning media to improve concept understanding by collaborating using snowball throwing learning models.

Provision of Physics Props and Bilingual E-Book for SMA YPK Merauke

Science is learned by bringing real objects in daily life into the classroom. Therefore, the props are needed in learning science to make it easier for students to observe the concepts of science contained in an object. However, not all schools have good props to use in learning. This dedication to society aims to provide props that can be used as a medium of physics learning at SMA YPK Merauke. The props are accompanied by bilingual guides so that students can learn physics and English at the same time. The devotional activities were carried out through the introduction of props to physics teachers, demonstrations on how to use bilingual tools and guides, and mentoring. At the end of the activity, physics teachers were given a user response sheet to find out the teachers' perception of the props given. The results of the user response sheet show that the props can be appropriately used as a learning medium. Then, more props are needed to be given to schools in Merauke that do not have good props. Abstrak Sains dipelajari dengan membawa objek yang nyata di kehidupan sehari-hari ke dalam kelas. Oleh karena itu, alat peraga diperlukan dalam belajar sains untuk memudahkan siswa mengamati konsep-konsep sains yang terdapat pada suatu objek. Akan tetapi, tidak semua sekolah memiliki alat peraga yang memadai untuk digunakan dalam pembelajaran. Kegiatan pengabdian masyarakat ini bertujuan untuk menyediakan alat peraga yang dapat digunakan sebagai media pembelajaran fisika di SMA YPK Merauke. Alat peraga tersebut disertai dengan panduan bilingual agar siswa dapat belajar fisika dan Bahasa inggris secara bersamaan. Kegiatan pengabdian dilakukan melalui pengenalan alat peraga kepada guru fisika, demonstrasi cara penggunaan alat dan panduan bilingual, serta pendampingan. Di akhir kegiatan, guru-guru fisika diberikan lembar respon pengguna untuk mengetahui persepsi guru-guru terhadap alat peraga yang diberikan. Hasil lembar respon pengguna menunjukkan bahwa alat peraga dapat digunakan dengan baik sebagai media pembelajaran. Ke depannya, diperlukan lebih banyak alat peraga untuk diberikan kepada sekolah-sekolah di Merauke yang belum memiliki alat peraga yang memadai.
