Computational thinking (CT) is an essential skill in the twenty-first century. The computational physics course (CPC) is one subject that is designed to support students in the practice of CT. Many studies show that the worksheets could be a solution in a CPC as a scaffold to achieve the CT objectives both online and offline. The study aims to develop the worksheet and integrate it with CT in a computational physics course. This study applied the research and development (R & D) method with the ADDIE model approach. In the results, the evaluation test from the experts reached a very good interpretation score based on the learning media expert (96%), the teaching material expert (95%), and the pedagogy experts (92%). So that this media is declared feasible to be used in the CPC. Furthermore, after the experimental study of students who took the computational physics course (n = 31), the study showed that the modified course could significantly improve student skills regarding overall CT (p value <0.05). However, this research also found that cooperative learning as part of CT had no improvement (p value >0.05). The experiment was conducted amid the COVID 19 pandemic wherein the students could only study at home for the whole semester. These findings indicate that the pandemic has impacted the collaborative skills of students on the course.

This study aims to disclose how virtual reality technology has been applied to studies of learning and the possibility of virtual reality by reviewing studies that have employed the virtual reality approach. A total of 15 papers were selected from the Scopus Index database from 2015 to 2020. Content analysis showed that virtual reality and physics learning had received the most attention under the theme of student perception, especially in self-efficacy and experience, followed by satisfaction, motivation, and engagement. Trends of research development show that the use of virtual reality has proliferated recently. Moreover, HTC Vive is the most powerful device to conduct the VR study for the tool device. This study concludes that virtual reality technology provides a promising media for educational researchers.

Exploration can be done by reading, discussing, or experimenting with collecting and processing data. In fluid material, students can explore by looking at the phenomena related to the application of Archimedes' law, Pascal's law, and Bernoulli's law. This study aims to develop teaching materials that can improve students' ability to explore fluid material. The research method used is the 4D model development research. The study results were in marker applications and augmented reality, which was validated by material experts, learning media. This application has also gone through field trials. The validation value of material experts is 86%, and media experts are 82.5%. Meanwhile, the test results for the teacher obtained 83.75%, and the students obtained 83.45%. Based on the validation results, this media is feasible to be used as a learning medium that helps students improve fluid material.

The simulation of physical phenomena between fluid and its boundary is a fascinating study because of its application in various fields of engineering. In this simulation, we analyze how fluids are arranged as granular particles with certain conditions interacting with the wall. The walls are varied as the characters that represent the shape of the breakwater building. This simulation compares the effectiveness of commonly used wave barriers. Wave barriers are used to hold the waves from reaching the land. In this, the simulation used two types of wave holders in the form of tetrapod and cubic, which are placed on a sloping surface. Next, an analysis of the farthest distances from the variations in the speed of the waves and the types of waves holds. Simulation results show that tetrapods are able to withstand wave speeds better than cubic.

Simulations were performed using markerless augmented reality on the concept of Compton scattering. Compton scattering identifies that photons can not only behave as waves but also behave like particles. The process of colliding photons with electrons causes dispersion which shows that the photon has momentum. This article will explain a photon collision simulation to prove the state of light dualism by utilizing augmented reality technology. The development of this simulation was tested using the black-box testing method. Interactive media using augmented reality for Compton scattering simulations can display the concept of collisions between photons and electrons. Our simulation successfully simulates the mechanism of energy release and momentum changes before and after the contact.

Granular simulations have been carried out to visualize attached to porous vertical surfaces. We simulate the optimal ratio of dry surfaces. This simulation uses the uFlex particle with three pore sizes. The movement particle using parabolic motion with the initial horizontal speed only. The simulation results show that for uniform particle velocities, the number of particles that are attached depends on the size of the particle sphere itself. These results can combine with the previous study to use in future research.

Hajj is one of the five pillars of Islam and is obligatory for qualified Muslims. This study aims to make a virtual reality application for hajj simulation. This study uses descriptive analysis method. The result of this research is an application that consists of 6 features, namely: features (hajj series, hajj series guide, Arabic language, floor plans, frequently asked questions, instructions for use). The Free Hajj will learn how to perform the Hajj not just a theory but also presents ideas, practices and actual conditions. Like being directly in Mecca.

Physics is not only learning through the presentation of concepts or formulas, but many events can be understood through various learning media. Evidently, students better understand the material if they can interact directly with the topic of the lesson. In addition, the rapid internet makes teachers are required to actively develop learning media. This research aims to develop physics learning using E-Learning learning media on the Special Theory of Relativity material for high school students in class XII. This study uses research and development methods that refer to the ADDIE model. This research is limited to making applications. Based on the results of research, this development has produced products that function well and present features that support student learning. Available features include quizzes, learning videos, materials and simulations that students can access. E-learning developed using Schoology can support learning through the online platform. E-learning using Schoology can display the stages of stimulus that can be determined by educators when using this e-learning. Therefore, e-learning learning that utilizes Schoology on relativity material can be designed and developed according to the needs of teachers and students in the learning process in class.
